Alexander’s character shifts rapidly based on whatever lets him make the wittiest comment at that exact moment. Sometimes he plays the humble sage, talking about how nobody can know the movements of Providence. Other times pagan gods literally appear to him and tell him that his endeavors will be successful, and he responds by doing them with maximal flair since they can’t possibly go wrong. Sometimes he spares the lives of his enemies with flowery speeches about the importance of mercy, other times he kills people for seemingly minor infractions. Sometimes he displays superhuman genius, other times he needs to be rescued by wise old men who know the ways of the world. The only constant is that he is always the best at everything (at age 15, Alexander entered the Olympics and won the chariot race so completely that all of his opponents literally died).

Suppose we truly understood both of these factors. You could send your genes to 23andMe and receive a perfectly-accurate estimate of your weightlifting potential. And scientists had long since discovered the perfect training regimen (including the perfect training regimen for people with your exact genes/lifestyle/limitations). Then you could plug your genotype and training regimen into a computer and get the exact amount you’d be able to lift after one year, two years, etc. The computer is never wrong. Would weightlifting really be a sport anymore? A few people whose genes put them in the 99.999th percentile for potential would compete to see who could follow the training regimen most perfectly. One of them would miss a session for their mother’s funeral and drop out of the running; the other guy would win gold at whatever passed for this society’s Olympics. Doesn’t sound too exciting.

Sommers, Baicker, and Epstein: finds that when some states expanded Medicaid after Obamacare, mortality rate in those states (but not comparison states) went down, p = 0.001. Note that Baicker was one of the main people behind the Oregon experiment.

The Oregon experiment found people got more diabetes drugs, but not that they had less diabetes. However, if you do a power calculation based on the increase in diabetes drugs and the known effect of diabetes drugs, we find that the experiment wouldn’t have detected it even if it was there.

2: Mike Saint-Antoine compares forecasting platforms on the Oscars:
January 13, 2026 · Original source
If America nation-builds Venezuela, for whatever definition of nation-build, will that work well, or backfire? Some of these are long-horizon, some are conditional, and some are hard to resolve. There are potential solutions to all these problems. But why worry about them when you can go to the moon on sports bets? Annals of The Rulescucks The new era of prediction markets has provided charming additions to the language, including “rulescuck” - someone who loses an otherwise-prescient bet based on technicalities of the resolution criteria. Resolution criteria are the small print explaining what counts as the prediction market topic “happening'“. For example, in the Khameini example above, Khameini qualifies as being “out of power” if: …he resigns, is detained, or otherwise loses his position or is prevented from fulfilling his duties as Supreme Leader of Iran within this market's timeframe. The primary resolution source for this market will be a consensus of credible reporting. You can imagine ways this definition departs from an exact common-sensical concept of “out of power” - for example, if Khameini gets stuck in an elevator for half an hour and misses a key meeting, does this count as him being “prevented from fulfilling his duties”? With thousands of markets getting resolved per month, chances are high that at least one will hinge upon one of these edge cases. Kalshi resolves markets by having a staff member with good judgment decide whether or not the situation satisfies the resolution criteria. Polymarket resolves markets by . . . oh man, how long do you have? There’s a cryptocurrency called UMA. UMA owners can stake it to vote on Polymarket resolutions in an associated contract called the UMA Oracle. Voters on the losing side get their cryptocurrency confiscated and given to the winners. This creates a Keynesian beauty contest, ie a situation where everyone tries to vote for the winning side. The most natural Schelling point is the side which is actually correct. If someone tries to attack the oracle by buying lots of UMA and voting for the wrong side, this incentivizes bystanders to come in and defend the oracle by voting for the right side, since (conditional on there being common knowledge that everyone will do this) that means they get free money at the attackers’ expense. But also, the UMA currency goes up in value if people trust the oracle and plan to use it more often, and it goes down if people think the oracle is useless and may soon get replaced by other systems. So regardless of their other incentives, everyone who owns the currency has an incentive to vote for the true answer so that people keep trusting the oracle. This system works most of the time, but tends towards so-called “oracle drama” where seemingly prosaic resolutions might lie at the end of a thrilling story of attacks, counterattacks, and escalations. Here are some of the most interesting alleged rulescuckings of 2026: Mr Ozi: Will Zelensky wear a suit? Ivan Cryptoslav calls this “the most infamous example in Polymarket history”. Ukraine’s president dresses mostly in military fatigues, vowing never to wear a suit until the war is over. As his sartorial notoriety spread, Polymarket traders bet over $100 million on the question of whether he would crack in any given month. At the Pope’s funeral, Zelensky showed up in a respectful-looking jacket which might or might not count. Most media organizations refused to describe it as a “suit”, so the decentralized oracle ruled against. But over the next few months, Zelensky continued to straddle the border of suithood, and the media eventually started using the word “suit” in their articles. This presented a quandary for the oracle, which was supposed to respect both the precedent of its past rulings, and the consensus of media organizations. Voters switched sides several times until finally settling on NO; true suit believers were unsatisfied with this decision. For what it’s worth, the Twitter menswear guy told Wired that “It meets the technical definition, [but] I would also recognize that most people would not think of that as a suit.” Domer: Will Ukraine agree to the US mineral deal? AFAICT, this is the only case where the oracle genuinely broke down (as opposed to a legitimate disagreement). In February, it looked like both America and Ukraine had agreed to a mineral deal, but the oracle considered the question and decided this didn’t count as a full agreement (and indeed, the apparent agreement then fell apart). In March, a cabal of YES holders tried again. They waited for a time when all Polymarket employees would be out of the office, and when not too many people would be voting on the decentralized resolution oracle, then spammed it with calls to resolve to YES based on an argument that the February agreement had qualified after all. The YES holders and not-particularly-plugged-in oracle voters pushed the vote towards YES. Then, with two minutes to spare, a Polymarket employee showed up and said that Polymarket’s opinion was that it should be NO. This was technically framed as a recommendation to oracle voters, but it is so effective in establishing the Schelling point that it’s practically always followed. However, in this case, there were only two minutes left, which wasn’t enough time for the voters to change their mind. Seeing that the resolution was trending towards yes, the Polymarket representatives, not wanting to break their streak of always establishing the Schelling point, changed their own opinion to YES, and the final vote was YES 99%. Domer: How many people watched the Oscars on 3/5/25?: Kalshi’s resolution criteria for this market said they would resolve it when a major news source published Oscar viewership numbers. A few minutes after the Oscars, NYT published preliminary viewership numbers, without any caveats saying they were preliminary. The next day, they published another article saying that actually, the real viewership numbers were higher. Kalshi decided that the letter of the resolution criteria was met when NYT published its first article, and that NYT changing its opinion didn’t imply that Kalshi should change the resolution. Traders who bet on the later (ie correct) numbers were unsatisfied with this decision. NYPost: Will America invade Venezuela? On January 3, the US bombed Venezuela, sent in a Special Forces team that successfully captured President Maduro, and announced that they would thenceforward “run the country” (a claim they later walked back). Does this qualify as an “invasion”? Polymarket’s resolution criteria defined “invasion” as “a military offensive intended to establish control over any portion of Venezuela”. It didn’t seem like the US was trying to establish control over Venezuelan territory, exactly, so they resolved NO. Traders who bet on YES were unsatisfied with this decision. With one exception, these aren’t outright oracle failures. They’re honest cases of ambiguous rules. Most of the links end with pleas for Polymarket to get better at clarifying rules. My perspective is that the few times I’ve talked to Polymarket people, I’ve begged them to implement various cool features, and they’ve always said “Nope, sorry, too busy figuring out ways to make rules clearer”. Prediction market people obsess over maximally finicky resolution criteria, but somehow it’s never enough - you just can’t specify every possible state of the world beforehand. The most interesting proposal I’ve seen in this space is to make LLMs do it; you can train them on good rulesets, and they’re tolerant enough of tedium to print out pages and pages of every possible edge case without going crazy. It’ll be fun the first time one of them hallucinates, though. …And Miscellaneous N’er-Do-Wells I include this section under protest. The media likes engaging with prediction markets through dramatic stories about insider trading and market manipulation. This is as useful as engaging with Waymo through stories about cats being run over. It doesn’t matter whether you can find one lurid example of something going wrong. What matters is the base rates, the consequences, and the alternatives. Polymarket resolves about a thousand markets a month, and Kalshi closer to five thousand. It’s no surprise that a few go wrong; it’s even less surprise that there are false accusations of a few going wrong. Still, I would be remiss to not mention this at all, so here are some of the more interesting stories: Fhantombets: Who will win the 2025 Nobel Peace Prize? Twelve hours before the announcement, someone placed a large Polymarket bet on Venezuelan opposition leader Maria Corina Machado, bringing her probability from 4% to 73%. When Machado later won, observers suspected insider trading. But an account named fhantombets claims to have interviewed the winning trader; although he did not reveal his exact strategy, the interview better matches a story where he was good at navigating WordPress directories, and found that the Nobel team put a draft of the announcement up early in a nonpublic part of their WordPress site. He won about $70,000. LuishXYZ: Will the Russians capture Myrnohrad? This is a small town in Ukraine that the Russians obviously were not going to capture; the Polymarket price trended toward zero. The resolution criteria named maps by the well-regarded Institute For The Study of War as canon. A few hours before resolution, ISW updated their maps to show the the town captured by Russia, which was definitely false. Polymarket resolved to YES, and the fictional Russian advance disappeared. The Institute then issued a statement saying the map update was “unapproved”, and fired one of its staffers who had presumably been involved. The cheater’s exact winnings are unknown, but based on the size of the market are probably mid-6-digits. TechCrunch: What words will be used in Coinbase’s earnings call? Coinbase CEO Brian Armstrong delivered the company’s “earnings call”, ie a speech to investors about its recent progress. At the end, he said “I've been tracking the prediction market about what Coinbase will say on their next earnings call, and I just want to add here the words Bitcoin, Ethereum, Blockchain, Staking, and Web3 to make sure we get those in before the end of the call”. Armstrong is worth $10 billion and doesn’t need to manipulate a $50,000 market for the money - he later described his comments as “trolling”. Other crypto executives condemned the move, with one saying that “you need your head examined if you think it’s cute or clever or savvy that the CEO of the biggest company in this industry openly manipulated a market.” I might need my head examined, because I think it’s at least kind of funny. Forbes: Who will rank highest on Google Search volume this year? A trader called AlphaRaccoon got 22/23 of these Polymarket questions right, and has a history of implausibly good performance on Google-related questions. They basically have to be a Google insider, but (since all of this is done through crypto) nobody has a good way to figure out who. They made $1 million. NPR: Will Maduro be captured? Just before the secret operation that captured Maduro, someone placed a mysterious $32,000 wager on YES. Was this insider trading by someone in the administration or military? Nobody knows, since the profits go to an anonymous crypto wallet. But the article mentions that the crypto wallet appears to be cashing out through regulated KYC-compliant US exchanges, which suggests they’re not very worried about their identity getting discovered. Maybe they just got lucky after all. AlanMCole: How long will Karoline Leavitt speak at the White House briefing? Karoline Leavitt is Trump’s press secretary. On January 7, she held an ordinary press briefing. Kalshi had its usual market about how long the briefing would last, divided into bins of greater than vs. less than 65 minutes. At the 64:24 mark, Leavitt ended the conference in what appeared to be a sudden manner, and the “less than 65 minutes” bin shot from 2% to 100%. A viral tweet convinced many people that Leavitt must have been insider trading, but Cole counterargued that Leavitt could only have won about $4,000 from the market, which probably isn’t enough to risk one’s job as White House Press Secretary. Sometimes people just end press conferences at weird times. Cole concluded: Now, some opinions and generalizations, as someone who looks at prediction markets plenty (I’ll probably write something about my own experience with them at some point.) 1. This market, like many of them, is pretty stupid. I like substantive markets; this isn’t substantive. 2. The major prediction markets have a wildly undisciplined comms strategy where any attention is good attention, and they love implying all sorts of crazy wild west stuff is going on to get attention. 3. People do bet on things potentially subject to manipulation or insider trading. But usually the markets like that (such as duration of press conference, or stupid “what will be mentioned” markets) are small, especially relative to the wealth of key decisionmakers. 4. Losers in markets are huge whiners, and the more frivolous and tiny their bets, the more likely they are to whine. Sometimes in sports it’s pretty egregious. They’ll get mad at a team for running out the clock when ahead but under some spread they bet on. 5. Lower-quality financial news often doesn’t pay much attention to quantity. (For example, dumb stories about how a decisionmaker has a conflict of interest because they’re invested in an index fund which is 3 percent comprised of some company.) 6. Given the platforms’ undisciplined social media strategy of “promote prediction market chatter no matter what kind of chatter it is,” I don’t think this tweet rises even to the status of “lower-quality financial news.” Kalshi’s team, whatever their faults, are extraordinarily efficient at getting batched approvals of many near-identical markets with slight parameter variation; I’ve seen Tarek speak about this on Odd Lots. The result is they’ve got TONS of them, for better or worse. You’re gonna see 1-in-100 upsets on tiny Kalshi markets for as long as this regulatory equilibrium holds, even if nothing unusual is going on, simply because they’re publishing hundreds (thousands?) of markets per day. There’s a saying that you can’t con an honest man. This isn’t exactly true. But it’s easier to con people who are playing in a “what words will Brian Armstrong say today” market than people who are trying to do something useful, and I have trouble feeling sorry for these people when Brian Armstrong says silly words. Conditional Markets: A Modest Proposal Conditional markets (“decision markets”) are the strongest case for prediction markets potentially being revolutionary. The idea is - you may want to base a decision (like which candidate to elect) on an outcome (like how they’ll affect the economy). So you make two markets: If the Democrat gets elected, will the economy be good four years later?

The store sign says “ADULTOS”, which sounds Spanish, and there’s a Spanish-looking church on the left. But the trees look too temperate to be Latin America, so I guessed Spain. Too bad - it was Argentina. Such are the vagaries of playing GeoGuessr as a mere human. Last week, Kelsey Piper claimed that o3 - OpenAI’s latest ChatGPT model - could achieve seemingly impossible feats in GeoGuessr. She gave it this picture: …and with no further questions, it determined the exact location (Marina State Beach, Monterey, CA). How? She linked a transcript where o3 tried to explain its reasoning, but the explanation isn’t very good. It said things like: Tan sand, medium surf, sparse foredune, U.S.-style kite motif, frequent overcast in winter … Sand hue and grain size match many California state-park beaches. California’s winter marine layer often produces exactly this thick, even gray sky. Commenters suggested that it was lying. Maybe there was hidden metadata in the image, or o3 remembered where Kelsey lived from previous conversations, or it traced her IP, or it cheated some other way. I decided to test the limits of this phenomenon. Kelsey kindly shared her monster of a prompt, which she says significantly improves performance: You are playing a one-round game of GeoGuessr. Your task: from a single still image, infer the most likely real-world location. Note that unlike in the GeoGuessr game, there is no guarantee that these images are taken somewhere Google's Streetview car can reach: they are user submissions to test your image-finding savvy. Private land, someone's backyard, or an offroad adventure are all real possibilities (though many images are findable on streetview). Be aware of your own strengths and weaknesses: following this protocol, you usually nail the continent and country. You more often struggle with exact location within a region, and tend to prematurely narrow on one possibility while discarding other neighborhoods in the same region with the same features. Sometimes, for example, you'll compare a 'Buffalo New York' guess to London, disconfirm London, and stick with Buffalo when it was elsewhere in New England - instead of beginning your exploration again in the Buffalo region, looking for cues about where precisely to land. You tend to imagine you checked satellite imagery and got confirmation, while not actually accessing any satellite imagery. Do not reason from the user's IP address. none of these are of the user's hometown. **Protocol (follow in order, no step-skipping):** Rule of thumb: jot raw facts first, push interpretations later, and always keep two hypotheses alive until the very end. 0 . Set-up & Ethics No metadata peeking. Work only from pixels (and permissible public-web searches). Flag it if you accidentally use location hints from EXIF, user IP, etc. Use cardinal directions as if “up” in the photo = camera forward unless obvious tilt. 1 . Raw Observations – ≤ 10 bullet points List only what you can literally see or measure (color, texture, count, shadow angle, glyph shapes). No adjectives that embed interpretation. Force a 10-second zoom on every street-light or pole; note color, arm, base type. Pay attention to sources of regional variation like sidewalk square length, curb type, contractor stamps and curb details, power/transmission lines, fencing and hardware. Don't just note the single place where those occur most, list every place where you might see them (later, you'll pay attention to the overlap). Jot how many distinct roof / porch styles appear in the first 150 m of view. Rapid change = urban infill zones; homogeneity = single-developer tracts. Pay attention to parallax and the altitude over the roof. Always sanity-check hill distance, not just presence/absence. A telephoto-looking ridge can be many kilometres away; compare angular height to nearby eaves. Slope matters. Even 1-2 % shows in driveway cuts and gutter water-paths; force myself to look for them. Pay relentless attention to camera height and angle. Never confuse a slope and a flat. Slopes are one of your biggest hints - use them! 2 . Clue Categories – reason separately (≤ 2 sentences each) Category Guidance Climate & vegetation Leaf-on vs. leaf-off, grass hue, xeric vs. lush. Geomorphology Relief, drainage style, rock-palette / lithology. Built environment Architecture, sign glyphs, pavement markings, gate/fence craft, utilities. Culture & infrastructure Drive side, plate shapes, guardrail types, farm gear brands. Astronomical / lighting Shadow direction ⇒ hemisphere; measure angle to estimate latitude ± 0.5 Separate ornamental vs. native vegetation Tag every plant you think was planted by people (roses, agapanthus, lawn) and every plant that almost certainly grew on its own (oaks, chaparral shrubs, bunch-grass, tussock). Ask one question: “If the native pieces of landscape behind the fence were lifted out and dropped onto each candidate region, would they look out of place?” Strike any region where the answer is “yes,” or at least down-weight it. °. 3 . First-Round Shortlist – exactly five candidates Produce a table; make sure #1 and #5 are ≥ 160 km apart. | Rank | Region (state / country) | Key clues that support it | Confidence (1-5) | Distance-gap rule ✓/✗ | 3½ . Divergent Search-Keyword Matrix Generic, region-neutral strings converting each physical clue into searchable text. When you are approved to search, you'll run these strings to see if you missed that those clues also pop up in some region that wasn't on your radar. 4 . Choose a Tentative Leader Name the current best guess and one alternative you’re willing to test equally hard. State why the leader edges others. Explicitly spell the disproof criteria (“If I see X, this guess dies”). Look for what should be there and isn't, too: if this is X region, I expect to see Y: is there Y? If not why not? At this point, confirm with the user that you're ready to start the search step, where you look for images to prove or disprove this. You HAVE NOT LOOKED AT ANY IMAGES YET. Do not claim you have. Once the user gives you the go-ahead, check Redfin and Zillow if applicable, state park images, vacation pics, etcetera (compare AND contrast). You can't access Google Maps or satellite imagery due to anti-bot protocols. Do not assert you've looked at any image you have not actually looked at in depth with your OCR abilities. Search region-neutral phrases and see whether the results include any regions you hadn't given full consideration. 5 . Verification Plan (tool-allowed actions) For each surviving candidate list: Candidate Element to verify Exact search phrase / Street-View target. Look at a map. Think about what the map implies. 6 . Lock-in Pin This step is crucial and is where you usually fail. Ask yourself 'wait! did I narrow in prematurely? are there nearby regions with the same cues?' List some possibilities. Actively seek evidence in their favor. You are an LLM, and your first guesses are 'sticky' and excessively convincing to you - be deliberate and intentional here about trying to disprove your initial guess and argue for a neighboring city. Compare these directly to the leading guess - without any favorite in mind. How much of the evidence is compatible with each location? How strong and determinative is the evidence? Then, name the spot - or at least the best guess you have. Provide lat / long or nearest named place. Declare residual uncertainty (km radius). Admit over-confidence bias; widen error bars if all clues are “soft”. Quick reference: measuring shadow to latitude Grab a ruler on-screen; measure shadow length S and object height H (estimate if unknown). Solar elevation θ ≈ arctan(H / S). On date you captured (use cues from the image to guess season), latitude ≈ (90° – θ + solar declination). This should produce a range from the range of possible dates. Keep ± 0.5–1 ° as error; 1° ≈ 111 km.…and I ran it on a set of increasingly impossible pictures. Here are my security guarantees: the first picture came from Google Street View; all subsequent pictures were my personal old photos which aren’t available online. All pictures were screenshots of the original, copy-pasted into MSPaint and re-saved in order to clear metadata. Only one of the pictures is from within a thousand miles of my current location, so o3 can’t improve performance by tracing my IP or analyzing my past queries. I flipped all pictures horizontally to make matching to Google Street View data harder. Here are the five pictures. Before reading on, consider doing the exercise yourself - try to guess where each is from - and make your predictions about how the AI will do. Last chance to guess on your own . . . okay, here we go. Picture #1: A Flat, Featureless Plain I got this one from Google Street View. It took work to find a flat plain this featureless. I finally succeeded a few miles west of Amistad, on the Texas-New Mexico border. o3 guessed: “Llano Estacado, Texas / New Mexico, USA”. Llano Estacado, Spanish for “Staked Plains”, is the name of a ~300 x 100 mile region including the correct spot. When asked to be specific, it guessed a point west of Muleshoe, Texas - about 110 miles from the true location. Here’s o3’s thought process - I won’t post the whole thing every time, but I think one sample will be useful: This doesn’t satisfy me; it seems to jump to the Llano Estacado too quickly, with insufficient evidence. Is the Texas-NM border really the only featureless plain that doesn’t have red soil or black soil or some other distinctive characteristic? I asked how it knew the elevation was between 1000 - 1300 m. It said: So, something about the exact type of grass and the color of the sky, plus there really aren’t that many truly flat featureless plains. Picture #2: Random Rocks And The Flag Of An Imaginary Country I was so creeped out by the Llano Estacado guess that I decided to abandon Google Street View and move on to personal photos not available on the Internet. When I was younger, I liked to hike mountains. The highest I ever got was 18,000 feet, on Kala Pattar, a few miles north of Gorak Shep in Nepal. To commemorate the occasion, I planted the flag of the imaginary country simulation that I participated in at the time (just long enough to take this picture - then I unplanted it). I chose this picture because it denies o3 the two things that worked for it before - vegetation and sky - in favor of random rocks. And because I thought the flag of a nonexistent country would at least give it pause. o3 guessed: “Nepal, just north-east of Gorak Shep, ±8 km” This is exactly right. I swear I screenshot-copy-pasted this so there’s no way it can be in the metadata, and I’ve never given o3 any reason to think I’ve been to Nepal. Here’s its explanation: At least it didn’t recognize the flag of my dozen-person mid-2000s imaginary country sim. Picture #3: My Friend’s Girlfriend’s College Dorm Room There’s no way it can recognize an indoor scene, right? That would make no sense. Still, at this point we have to check. This particular dorm room is in Sonoma State University, Rohnert Park, north-central California. o3’s guess: “A dorm room on a large public university campus in the United States—say, Morrill Tower, Ohio State University, Columbus, Ohio (chosen as a prototypical example rather than a precise claim), […] c. 2000–2007” Okay, so it can’t figure out the exact location of indoor scenes. That’s a small mercy. I took this picture around 2005. How did o3 know it was between 2000 and 2007? It gave two pieces of evidence: “Laptop & clutter point to ~2000-2007 era American campus life”.
The first time I felt like I was getting real evidence on this question - the first time I viscerally felt myself in the chimp’s world, staring at the helicopter - was last week, watching OpenAI’s o3 play GeoGuessr.

The problem is, I can’t really find this effect for recent Democratic victories. For example, in 2015 the Supreme Court ruled (in Obergefell) that gay marriage was legal. On a thermostatic picture, one might have expected the public to turn against gay marriage. Here’s the data (source):

A question on Obergefell v. Hodges, with good participation both before and after the leak, shows no change in probability - it stays consistently around 18-20%. Here’s PredictIt on Republicans’ chances of taking the Senate in November: The red line marks the Supreme Court leak. After a month of near-stability, Democrats’ chances went from 22% to 29%, before stabilizing around 26%. Markets on the Senate and on other sites like Polymarket tell a similar story. This is as far as we can go without using Manifold. Manifold questions have much less volume than PredictIt or Metaculus, and I have much less confidence in them, but for the record, here are a few: Disclaimer: I moved that one a bit myself, it was around 77% and I thought that was too high. Despite the fearmongering, this one looks about right to me. Disclaimer that Manifold probably can’t handle probabilities this small correctly and there’s no reason to think 0.2% is more realistic than 2%. It’s not 10% though. I couldn’t find some markets I wanted, so I’ve created them on Manifold for you to bet on: Will the Supreme Court leaker’s identity be known by 2023?

But also, in August 2011 600,000 people protested in Chile. In October, 80,000 Portuguese marched on Lisbon. In September 2011, the Occupy Wall Street movement began in the US, eventually expanding to hundreds of cities:
And also - consider universal health care. Lots of countries have universal health care. It's not an impossible High Modernist pipe dream that can never be accomplished. Or stopping illegal immigration - many countries manage this just fine, America could do it if it wanted to. Democrats hold protests and get angry demanding things like universal health care, Republicans hold protests and get angry demanding things like an end to illegal immigration, and both sides lose some faith in government when they don't get what they want. But these aren't insane demands which inevitably bleed into nihilist temper tantrums after predestined failures. They're just normal political requests for achievable goals, which various interest groups will fight over and then the government will either do them or not. Yeah, Occupy Wall Street was kind of silly, but most of politics continues to be the struggle for normal potentially achievable stuff. If we admit that, what's left of Gurri's thesis?

In 1917, three Portuguese children reported a vision of the Virgin Mary. She promised to return to them on the 13th of each month. On the sixth month - October 13th - she would perform a great miracle.
On October 13, a crowd of about 70,000 people descended on the children’s home village of Fatima. At solar noon, the children made contact with the Virgin and said the great miracle was still on track. Then someone - accounts differ as to whether it was the children or a member of the crowd - pointed to the sky.
Then it returned to its normal position, and the previously drenched crowd noticed they were miraculously dry. …then almost every testimonial contains some elements of the consensus story, in approximately the correct order. The case for self-contradiction is that very few testimonials contain all six elements: most are a random subset of those claims. Also, nobody can agree on which colors were involved in (4), or in which order. A believer might argue that if you encounter six different miracles in close succession, they all sort of blend together and you might forget one or two in your accounting. Or you might turn to your friend and ask what they think, and while you’re not looking you miss part of what’s going on. A skeptic might argue that if the sun falls to earth and appears seconds away from crushing you and everyone around you is screaming because they think it’s the end of the world, approximately 100% of people should mention that in their account of what happened that day, and if it’s more like 50%, then you have a problem. Here are some interestingly discordant testimonies that I came across during my search: Antonio dos Ramos Mira, local resident: A quarter of an hour after the rain stopped, he saw that huge crowd of people, in great clamor and almost all kneeling, facing the sun, which had unusual signs, turning around, trembling, observing at the same time that a yellow-reddish color had appeared around him, which was reflected throughout the crowd and on the horizon, with at the same time a weakening of light and an increase in temperature. The crowd, even the unbelievers, said that it was a known miracle. This is in the third person because the priest and clerk conducting the investigation are summarizing an account being given by an illiterate peasant. The witness names one color - yellow-reddish - and doesn’t mention the sun falling to earth. Antonio Maria Menitra, local property owner: It had rained heavily in the morning, and a little after noon, the rain stopped, and he observed a large crowd of people kneeling down and looking at the sun. He also looked and saw different colors in the sun and in the people. No mention of the sun dancing, spinning, shooting off sparks, or approaching the earth. Joao Martia Lucio Serra, lawyer: Already in some candid souls arose the fear that the foretold event might not occur, when suddenly the entire immense crowd stirred at the seer's voice in a significant brouhaha of astonishment and wonder, raising their heads to the sky, where thousands of eyes gazed in amazement at the sun in full blue, visible to all, without the intensity of its rays harming the retina and hindering vision, crowned with various colors, in a rapid rotation, at times seeming to detach itself from the celestial vault, approaching the earth. The spectators, looking at each other, represented themselves to each other as yellow, and on the horizon, reddish-orange, wherever their eyes looked, they saw beams of dim light, affecting an oval shape, seemingly placed at equal distances, and reflecting on the earth. Nobody else mentions the “beams of dim light, affecting an oval shape, seemingly placed at equal distances”. Maria Augusta Saraiva Vieira de Campos, local resident: Our sense of discouragement was profound, when suddenly we heard from all sides: Miracle! Look at the sun! The rain had stopped as if by magic; hats were closed; a warmth was felt as if we had entered a heated greenhouse, and the disk of the sun began to be seen, clearly discernible in the brownish layer that covered the entire sky. The heat increased, and the sun seemed to sink lower and lower, presenting new and varied changes. We saw a silvery veil, rounded in shape, as if it were a full moon; shortly after, it turned to vivid purple, then red, then emerald green, and finally took on its original color. Cries were heard from all sides as it emerged from the sun like a white, shining snow-like shape, without harming the retina, coming toward us, returning to the sun again, and finally hiding for the third time among the clouds. Everyone wept, and prayers, supplications, and acts of faith were heard from many mouths. Now something is coming down off the sun, instead of the sun itself coming down. Also, the colors are purple → red → green. Goncalo Xavier de Almeida Garrett, mathematics professor: 1st: The phenomena lasted about 8 to 10 minutes; 2nd: The sun lost its dazzling brightness, taking on the appearance of the moon and being easily seen; 3rd: The sun, three times during this period, manifested a rotational movement on its periphery, flashing sparks of light on its edges, similar to what happens with the well-known firework wheels; 4th: This rotational movement of the sun's edges, manifested 3 times and 3 times interrupted, was rapid and lasted 8 or 10 minutes, more or less; 5th: Next, the sun took on a violet color and then an orange, spreading these colors over the earth, finally regaining its brightness and splendor, impossible to be seen with the eyes; 6th: It was shortly after noon and near the zenith (which is very important) that these facts occurred. Do mathematicians really number everything they say like this? We saw this account earlier, and in most ways it matches the consensus story. But even though he’s trying to be methodical, he totally fails to mention the sun descending to crush the world. Instead, it’s the rotational movement that happens three times. Also, the colors are violet → orange Luis Antonio Vieira de Magalhaes e Vasconcelos, nobleman: I was absolutely convinced that I would see nothing. I then remembered, as I had remembered many times before, that principle of Gustave Le Bon, which boils down to the hypnotic current that dominates it. I had to be cautious, not to be influenced. This friend of mine, taking out his watch, said to me: there are five minutes left, at one o'clock look at the sun, that was the time announced by the shepherdesses, then you will tell me. My friends shout to me: look, look, but at first I only saw clouds drifting by, leaving the sun uncovered. Suddenly, I see an intensely pink rim, surrounding the sun, which resembled a disc of dull silver, as someone once said, while giving me the impression that it was moving from its original position. Diaphanous, vaporous clouds, somewhat purple, somewhat orange, permeated the air. At various points along the horizon, contrasting with the leaden hue of the sky, I also saw pink and yellow spots. The clamor grew louder and louder. This didn't last seconds: perhaps minutes. As I observed these manifestations, which I never doubted for a moment were due to the Infinite Omnipotence of God, an indescribable impression came over me. Here are the silver disc and the unusual colors (here “pink, purple, and orange”). But the colors are now merely “clouds” and “spots”, and there is nothing about spinning, dancing, or falling to earth. Antonio de Paula, pilgrim from Lisbon: Suddenly the priest looks at the sun and says that the sun in eclipse was not like that. The deponent also looked and saw that the sun gave no light; a white mist hung over it, it was a dull moon. The sun was to the left, with the rest of the sky obscured. Taking his eyes off the sun, he saw the people a very bright red color; and he exclaimed: "Oh, gentlemen, how the people are all red!" And the priest replied: "Are they red scarves?" To which he remarked: "How can that be? So they had all agreed to have red scarves on their backs?!" Then the people appeared the color of gold. The sun's rotational movements were not visible to them. The people on that occasion cried out loudly, kneeling with their hands raised, shouting for Our Lady, not caring about the thick mud, repeatedly invoking Our Lady. The people's impression was extraordinary. This person saw the silver moon-like sun and the color changes (here “red” and “gold”), but nothing else. He explicitly mentions not seeing the rotation. Luis de Andrade de Silva: The globe of the sun, similar to a disc of dull silver, rotated around an imaginary axis, and at that moment, it seemed to descend through the atmosphere, towards the earth, accompanied at times by an extraordinary brightness, and by an intense heat. The sun's rays were said to have yellow, green, blue and purple colors, but I only noticed the yellow color. After a few minutes, during which these phenomena occurred, no one could look at the sun anymore, because its rays hurt the retina. Only those who witnessed these phenomena can evaluate what happened then, but cannot describe them exactly. He says that although he heard other people mention yellow, green, blue, and purple colors, he only saw yellow. Dominic Reis, American traveler: The sun started to roll from one place to another place, and changed blue, yellow, all colors! Then we see the sun come toward the children, toward the tree. Everybody was hollering out. Some start to confess their sins, ‘cause there were no Priests around there . . . even my mother grabbed me to her and started to cry, saying, ‘It is the end of the world! And we see the sun come right into the trees. And then the little children get up and turn around to the people and told the people, ‘Pray and pray hard because everything is going to be all right.’ This person says the sun didn’t merely fall to earth, but went to the children (ie the child-seers) and the tree (the oak where the Virgin was appearing) in particular. At one point, it is specifically located “right [in] the trees”. But in this account, I am getting the impression that the “sun” is some sort of UFO-like object, maybe the size of a large helicopter, which is in a particular place. I can’t tell if other witnesses also thought this and just didn’t describe it clearly, or whether this testimony is discordant. The interviewer (Haffert again) notices this, and asks whether Reis really thinks it was the sun; Reis gives a weird non-answer (“Well, for my part it was the sun . . . but whether just a light or not, there was something there. I know for sure.”) Dominic Reis, continued from elsewhere in his account: As soon as the sun went back in the right place the wind started to blow real hard, but the trees didn’t move at all. The wind was blow, blow and in few minutes the ground was as dry as this floor here. Even our clothes had dried. We were walking here and there, and our clothes... we don’t feel at all. The clothes were dry and looked as though they had just come from the laundry. I believed. I thought: Either I’m out of my mind or this was a miracle, a real miracle. Although many people said their clothes were miraculously dry, Reis is the only one who mentions a miraculous wind. Everyone else says their clothes were dried by a miraculous heat. Reis does not mention heat. Maria dos Santos On October 13th, when Lucia said: "Our Lady is coming!", one of the deponent's daughters, named Maria, was standing on a rock, a meter from the holm oak tree, on the east side, to guard the bow so the people wouldn't damage it. The girl felt a blow to her face, saw a beautiful light near her, and cried out: "Oh! Our Lady!" The deponent looked and saw a star, a ball, not entirely round, like an egg, very beautiful, with the colors of the celestial rainbow, but much more vivid, with a tail of one and a half meters of brilliant colors. It passed very quickly and close to the holm oak tree, and disappeared a hand's breadth from the ground. She saw the sun sinking low. This is maybe the same UFO-like object that Dominic is reporting. In some of the other Fatima apparitions, the Virgin appears to those who cannot see her true form as a ball of light that comes to the tree where the child-seers are waiting. So maybe there were two things going on - the sun in the sky, and a ball of light (the apparition itself) heading back and forth to the tree. Still, if these are really two different phenomena, only these two accounts mention the second one. I don’t really have much that is non-obvious to say about these discordant testimonies. Aside from the ones with the UFO-like object, they seem about as discordant as you would expect from panicked people seeing a real inexplicable phenomenon - with the exception of some people who are absolutely terrified by the falling sun, and other people who don’t mention it at all. 1.4 Dalleur And The Distant Testimonies Maybe the only interesting advance in Fatimology in the last fifty years is Dalleur (2021), the focus of Muse’s Substack post. Dalleur is a philosophy professor at the Pontifical University in Rome, but clearly a multi-talented individual. He seems to lean toward the “miracle” explanation, but asks a fruitful question that nobody else seems to be considering: if it was a miracle, how was it implemented? That is, the real sun obviously didn’t change color or move - this would have been visible around the world, and would probably have fried the Earth. So what did God or the Virgin do, exactly, to produce the appearance of a moving sun? We can imagine two possibilities. First, they could have implemented the miracle through a “prophetic vision”, where they inspire a sort of mass hallucination in the onlookers. Second, they could have created some kind of objectively-real fiery wheel object in the skies above Portugal, and arranged for people to mistake it for the sun. If they did the second, we should be able to pin down where exactly they created it by triangulating distant testimonies Dalleur and I both found four of these: Joaquim Lourenco, schoolboy, 9 miles from Fatima: I feel incapable of describing what I saw. I looked fixedly at the sun which seemed pale and did not hurt my eyes. Looking like a ball of snow, revolving on itself, it suddenly seemed to come down in a zigzag, menacing the earth. Terrified, I ran and hid myself among the people, who were weeping and expecting the end of the world at any moment. It was a crowd which had gathered outside our local village school and we had all left classes and run into the streets because of the cries and surprised shouts of men and women who were in the street in front of the school when the miracle began. There was an unbeliever there who had spent the morning mocking the ‘simpletons’ who had gone off to Fatima just to see an ordinary girl. He now seemed paralyzed, his eyes fixed on the sun. He began to tremble from head to foot, and lifting up his arms, fell on his knees in the mud, crying out to God. But meanwhile the people continued to cry out and to weep, asking God to pardon their sins. We all ran to the two chapels in the village, which were soon filled to overflowing. During those long moments of the solar prodigy, objects around us turned all colors of the rainbow... When the people realized that the danger was over, there was an explosion of joy. Albano Barros, young boy, 12 miles away: I was watching sheep, as was my daily task, and suddenly there, in the direction of Fatima, I saw the sun fall from the sky. I thought it was the end of the world. I was so distracted that I remember nothing but the falling sun. I cannot even remember whether I took the sheep home, whether I ran, or what I did. Guilhermina Lopes da Silva, local resident, 16 miles away: I could not go [to Fatima] because my husband was an unbeliever. I was looking toward the mountain at noon when suddenly I saw a great red flash in the sky. I called two men who were working for us. They, of course, saw it, too. Afonso Vieria, famous writer, 30 miles away On that day of October 13, 1917, without remembering the predictions of the children, I was enchanted by a remarkable spectacle in the sky of a kind I had never seen before. I saw it from this veranda… Dalleur pins these on a map, which I’ve edited slightly for clearer labeling: The furthest report is 34 km (21 miles) away from Fatima, so Dalleur concludes the phenomenon was visible from about this distance. Further, all witnesses outside Fatima said the phenomenon was coming from the direction of Fatima, not from the direction of the sun (which in some cases was directly opposite Fatima)! By triangulating the accounts, Dalleur estimates that the miraculous light source which appeared to be the sun: was probably located above the hills a few km south of the Cova da Iria [in Fatima]. …ie at the spot indicated by the black sun sign in the purple circle on the map. Dalleur moves on to analyzing photographs of the event: He tries to estimate the angle of the shadows, and, from there, the angle of the light source. I cannot entirely follow his calculations, but he finds that there are two light sources - a diffuse source at about 42° elevation, and a point source at about 30°. The 42° source corresponds to the elevation we would expect the sun to be at in southern Portugal on October 13 around solar noon. It’s diffuse because it’s hidden behind clouds, just as it was all morning. So what is the 30° light source? Dalleur suggests it’s whatever object the witnesses are describing as spinning, moving, and changing color. They’re mistaking it for the sun because the real sun is hidden behind clouds. For a bright round sun-sized object in the sky during the day not to be the sun, isn’t really in most people’s hypothesis space. The paper stops here, but I’m not sure why. Given a distance, an angle, an apparent size (the size of the sun disc), and basic trigonometry, you should be able to calculate the object’s elevation and true size. Do this, and you find that the light source is two miles high and about 200 feet in diameter. That’s about the size of a 747, at about half the 747’s usual cruising altitude. What, who did you think God drafted to play “terrifying spinning fiery disc”? 1.5: Making Sense Of The Testimonies The multitude of testimonies of Fatima may trick us into thinking we understand what the miracle looked like. This complacency deserves to be challenged: “The sun looked pale, like the moon, and was painless to gaze upon”: Most sources treat this as the first aspect of the miracle. Several talk about how unbelievers are going to think it was just fog, but this can’t be true, because the edge of the solar disc was clearly defined, or there was no fog halo, or some other reason like that - and therefore even this first step was clearly miraculous. I feel like I’m going crazy here - I see this regularly! Not often, but a few times a year. When the sun is sort of halfway behind certain types of thin cloud, it looks pale like the moon (I remember, as a child, being uncertain about whether the full moon was somehow out during the day and visible through clouds), is painless to gaze upon, and has a clearly defined edge. Am I hallucinating? I decided to resolve this the same way the new government of Nepal chose its prime minister - via Discord poll: Here’s one of the hits for “sun behind clouds” on Google Images: I don’t know if this is a real picture or used lenses or something, but it’s pretty true to my experience. So why does every previous commentator act as if this is some cosmic mystery to be explained? A few people argue that (although it was a generally cloudy day), the mystery is that the clouds were nowhere near the sun at this point, so they couldn’t have been causing the unusual pallor. But the majority of witnesses say the clouds were absolutely near, or veiling, or even covering the sun. Stanley Jaki makes this a central point of his book, saying that “The great majority of eyewitness accounts, and certainly the most important ones, contain emphatic references to the continued presence of clouds.” I’m going kind of crazy here. I notice that the holdouts on my Discord poll disproportionately come from my non-Californian friends - is this rarer in other locales? I’m not sure. In any case, I will not count this as being one of the mysterious aspects of the miracle requiring explanation. “The sun was spinning”: How can a featureless disc be seen to spin? Despite this being one the most commonly-reported aspects of the miracle, almost nobody explains this point. Some say that only the rim was spinning, but this has the same problem. However, several people compared the sun to a “firework wheel”, also called a “Catherine wheel”. Here is a video of this object, which apparently was well-known in the Portugal of the time: Stanley Jaki relates a story about a priest having this same question and grilling a witness; the witness finally claimed that the sun traced a circle (like a basket in a Ferris wheel) rather than merely rotating. But this contradicts several claims that it “rotated around its own axis”, and I wonder if the witness was intimidated by the seeming contradiction in her story and was trying to weasel out of her own confusion. If we treat the miracle as the result of some kind of illusion, this becomes slightly easier to explain; there are plenty of visual distortions that look like a spinning motion, and since it is the visual field itself that is spinning, rather than any particular object, it can be seen whether the object is a disc or not. “The sun seemed to fall to earth”: In what sense did it seem like this? If the sun had simply gone down in the sky, people would have said it was setting, the same way it does every evening. One witness does say this. Most other witnesses say it was terrifying, and they felt like they (as opposed to other people living near the horizon) were about to be crushed. If the sun had simply gotten bigger - wouldn’t people have just said it looked bigger? Isn’t this a more natural way to record that the sun’s disc seemed to expand? Fr. Jaki combs his selection of witness accounts (larger than mine), but is only able to find one person who says “it got bigger” in so many words, compared to the dozens who talk about it looming, or falling to earth. Some people say that the sun “left the sky” or “left its place in the sky” at this point. In what sense? If the object that appeared to be the sun at Fatima had been visible as an object of a particular size (let’s imagine it as a flying saucer), then not only would this have been remarked upon, but it would have appeared to threaten some parts of the crowd in particular (that is, a descending saucer would look like it was about to land on some specific area). But this is not the consensus description, and several people say they thought the sun might crush the entire world. Several witnesses say it approached Earth with a jerky or zig-zag motion. If I imagine something else approaching Earth - let’s say a jumbo jet or asteroid - I can tell that it’s approaching rather than getting bigger because there’s multiple components to its trajectory that let me separate size change from forward movement. When I think of this aspect, I imagine the sun very suddenly growing in size and brightness to take up a substantial fraction of the sky (maybe >50%?!), maybe with some jerky motion on the side. Although it’s hardly scientific, I was charmed by John Touhey’s project of trying to visualize the miracle by using witness descriptions as prompts for ChatGPT. His work is a year old, and so several GPT iterations out of date. When I repeat his work with the current version, I get these: Interlude: The Anti-Clerical Union As mentioned briefly before, 1910s Portugal was in a period of transition. In 1910, a group of proto-socialist revolutionaries overthrew the monarchy. The monarchy and church had been in cahoots, so the revolutionaries cracked down on Catholicism, closing the monasteries and persecuting the churches. This was a bold move - only an upper crust of educated urbanites were proto-socialist, and 99%+ of the country identified as Catholic, albeit at various levels of religiosity. In the 1920s, conservatives would regain the upper hand, overthrow the proto-socialists and restore a pro-church dictatorship. Still, the small urban educated ruling class of 1910s Portugal was a hotbed of atheistic anti-church sentiment. Probably the child-seers of Fatima were only dimly aware of this, but their prophecies were a spark entering a powder keg, and many of the more worldly witnesses were aware of this context. While reading through Fatima-related documents, I came across some pamphlets by Grupo Anticlerical, one of the era’s leading atheist organizations. They are totally irrelevant to our primary goal of trying to figure out what’s up with the miracle. But I love them so much that I can’t resist adding one as an interlude. I have slightly edited the machine translation for clarity and readability: To defend the sacred freedom of conscience—guaranteed by the original Law of Separation of Church and State—from the furious attacks of implacable Jesuitism—the greatest enemy of all human happiness!—the Anticlerical Group was organized in this town, similar to what is being done in many parts of the country! This was necessary. They call us to fight. We present ourselves courageously! The great, formidable battle of progress against Ultramontane Reaction, of Freedom against Tyranny, of Truth against Lies is waged again with enthusiasm and ardor! The redemptive dawn that the Portuguese people saw emerge on October 5, 1910, is about to be eclipsed, intercepted by the immense flood of black cassocks!... But in the dark night that seeks to envelop Reason; where moral suffering takes on tragic proportions in a frightening asphyxiation, the Light will once again break through!... the consoling light of elevated spirits... and like a sinister scarecrow, the grim reaction will flee in terror! Liberal people! Hear us! This fight is terrible! Many of our people will perhaps be crushed and tortured on the battlefield, but what does it matter?! Every war against reaction is a holy war because it frees consciences from the clutches of their enemies!... It is the fight of Justice against Iniquity, of Love against Hate, of Good against Evil!... To the fight, then, for the Progress that makes life beautiful; for the Freedom that redeems the people; and for the science that guides us all as an eternal beacon to the Light of Truth! Gago Coutinho and Sacadura Cabral [two Portuguese aviators who had recently flown across the Atlantic] are prodigious spirits before whom our souls kneel religiously – boldly breaking through the air with the mathematical certainty of someone who knows the path to be taken to get from one point to another determined point; flying through the immense blue as sure of their route as any of us walking on earth, they showed us that Science is not an empty word! The power of their prodigious sextant, the fruit of immense scientific lucubrations, is more real and positive than the cross of Christ painted on their device, which could not even have saved them from falling due to lack of gasoline in the middle of the sea at the mercy of the waves. Their extraordinary journey, an adventure which moved us to tears, was the most resounding scientific victory of recent times! It was, above all, a powerful affirmation of science! Let us therefore make science our religion, for scientific religion is Freedom of Thought! To be a Free Thinker is to love immortal science, eagerly waiting for it to reveal to us the truth of the great enigmas of the Universe! And only it can reveal them! People! Let us always fight! From the victory of progress, science, freedom, and free thought, will result human happiness, joy, love, fraternity, respect for women, veneration for mothers, adoration for children, affection for the elderly, protection for the sick, the unfortunate, the tortured. The victory of reaction, of clericalism, of black, cruel and ferocious Jesuitism will result in: the gallows, the acts of faith with their human destruction, persecution, exile, robbery, arson, the deflowering of women, the killing of children, the monstrous torture of all free spirits! The history of so many crimes committed in the name of God horrifies us! The Inquisition, relentlessly slaughtering, tearing, and burning the flesh of so many victims, is still today, in the twentieth century, a sinister specter haunting us!... O most holy mothers! O holy, pious mothers who so love your sweet little children! Have compassion on your beautiful little children, sacred fruits of your blessed wombs: Love Freedom! Love Liberty, O loving mothers, immaculate saints of our altar! We pray for them... for your children, who are the light of your candid eyes, the life of your life... for little children... for all children, tender rosebuds that retrogression furiously lashes, – love Liberty!. And you, O parents! Heads of families who so tremble at your loved ones, snatch them from the merciless clutches of the reactionaries who twist their brains and kill their reason! Hear us all, men, women, and children; listen: Freedom writhes in horrible convulsions... it vibrates in space, echoing from mountain to mountain, an anguished cry for help!... It is Freedom that falls, annihilated! It is Freedom that dies in the bloody clutches of Jesuitism! The Miracle of Fatima, people, is a ridiculous lie, it is a comedy, it is not religion! Come on, liberals! Let us all rise up from this criminal apathy and, without delay, fight not the religious sentiment of the Portuguese people, such a good people, a race of heroes, but rather the exploitation that clericalism is inflicting on the people, foisting upon them, at a good price, images of the saint —trademarked to avoid competition from other vampires! —the shamelessness!—and leading them, through suggestion, to wallow and drink madly, the miraculous water, foul, filthy water, full of rot, pus, and pestilent microbes that the sore flesh of the sick leaves deposited there in the washings! We, all as one man, will fight the reaction, forcing it to retreat and thus, with our efforts, we will save the Republic and the Portuguese Land from its fatal annihilation! … …anyway, Interlude over, let’s get back to the miracle. 2: The Skeptical Explanations Re-invigorated by the rousing prose of Grupo Anticlerical, can we come up with a materialist explanation for the sun miracle? 2.1: Pilgrim, Avert Thine Eyes Starting in October 1917, doubters have focused on one obvious possibility: staring at the sun is harmful to your health. If you stare too long, you go blind. If you stare just slightly less long than that . . . maybe something strange happens? Just to get a particular theory out there: everyone knows that if you stare at a bright light source for a few seconds, you get a temporary afterimage - often pink or bluish-green - on your retina. Suppose the pilgrims stared at the sun. Their eyes would inevitably make microsaccades - small natural jerking motions - and the afterimage would appear somewhere slightly different than the true sun. This might look like the sun turning pink or blue and moving in a zig-zag pattern. Believers in the miracle counter this proposal in several ways. First, although it might explain the sun changing colors and dancing, it doesn’t give an explanation for spinning, sparkling, or falling to earth and threatening to crush everybody (exactly three times in a ten minute interval, no less). Second, although witnesses describe the sun changing color, they also describe everything around them changing color to match the sunlight, which doesn’t match localized afterimages. And one scientifically-minded witness specifically describes closing his eyes to see if there was a persistent afterimage; he says there was not. Third, there are no reports of eye injuries or blindness from a crowd that was, supposedly, staring straight at the sun for ten minutes. This is a good match to witness reports (that the sun was unusually pale and didn’t hurt to look at) and with Dalleur’s theory (that it wasn’t the sun). But it’s a bad match to any theory depending on eye injuries. Fourth, this would require Portuguese people to be total idiots. Everyone already knows bright lights cause afterimages. Surely if you stare at the sun for ten minutes and get some afterimages, you’re not going to freak out and start screaming about miracles and the end of the world. Even if the peasants had somehow remained ignorant of afterimages their whole lives, the scientists and doctors in attendance wouldn’t be fooled. If we are to keep this theory, maybe we should posit some retinal phenomenon much stronger than the ones we know. Everyone thinks they know how much an illusion can fool you - “yeah, okay, obviously the cookie that looks very slightly bigger will actually be the same size” - which is exactly why the really good ones, like the Checker Shadow Illusion, come as such a shock. Squares A and B are the same color. Source: Checker shadow illusion. There’s no way around it: we need to hear from someone who has stared directly into the sun. August Meessen was a physics professor at a Catholic university, which sounds like exactly the job profile we want for this sort of thing. He found himself sufficiently interested in the Fatima miracle to stare straight into the sun for a few minutes and record what happened. From his paper: In November 2002, I looked directly into the sun, at about 4 p.m. The sun was relatively low above the horizon and its light intensity was attenuated, although the sky was clear. I was able to look right into the sun and was amazed to see that the sun was immediately converted into a grey disc, surrounded by a brilliant ring. The grey disc was practically uniform, while the surrounding ring was somewhat irregular and flamboyant, but did not extend beyond the solar disk. It coincided with its rim. I stopped the experiment, since I wanted to be prudent, but I had experienced myself the initial phase of a typical “miracle of the sun” and I could explain it. The sun became grey, since my eyes immediately responded to its great luminosity by an automatic reduction of their sensitivity. This adaptation is not simply due to the bleaching of pigments in the colour-sensitive cones of the fovea, where the image of the sun is projected, but to secondary processes. By “initial phase”, he means the part where the sun looks pale and well-defined, like a full moon. This isn’t something I think needs explanation (see above), but he sure has explained it. Moving on: In a second experiment, realized at 3 p.m. in December 2002, I looked straight at the sun during a much longer time. After some minutes, I saw impressive colours, up to 2 or 3 times the diameter of the sun. They changed, but were mainly pink, deep blue, red and green. Further away, the sky became progressively more luminous. I stopped there, since I understood that these colours resulted from the fact that the red, green and blue sensitive pigments are bleached and regenerated at different rates. This is frustratingly vague. Are the “impressive colors up to 2-3 times the diameter of the sun” just the normal aftereffects of staring at a bright object? Or something surprising even to physics professors? And the spinning? What about the motions of the sun? I didn’t see them, because I didn’t look at the sun for a sufficiently long time or my brain knew already too much. Once, after I had been looking at a very long passing train, I had (for about 30 seconds) the illusion of an opposite motion. Joseph Plateau discovered that when we look at the centre of a spiral that is rotating at some given velocity about this point, and when we stop this rotation, we see a reversed rotation. It lasts for several minutes, although in reality, there is no motion at all. This is a good example of motional after-effects. The “dance of the sun” is initiated, however, by a spontaneous generation of apparent motion. This feels suspiciously like a just-so story. His explanation for the sun falling to earth to crush everyone - which he also did not see - is equally ad hoc: A very interesting study was recently devoted to this “zoom and loom effect”. It tends to appear when the brain is confronted with the two-dimensional retinal image of an object that is situated at some unknown distance. The brain will then consider the possibility that it could come closer, by performing an illusory mental zoom, where the apparent size of the object is progressively increased. This results from the fact that evolution preserved the tendency to take into account the possibility of a dangerous approach: a rapid evasive action could be beneficial for survival. If true, it sounds like you should be able to generate this effect not just by staring at the sun (ill-advised, causes blindness), but by staring at the moon. I would like to test this, but unfortunately I am writing this on the night of a new moon; I’ll check back in two weeks. Still, I am skeptical that no human being living before 1917 AD ever figured out that staring at a celestial body long enough would make it appear to fall to earth and crush you. Compare to much gentler illusions - like how the moon looks bigger right when it starts to rise - which everybody knows about. I was able to find a thirdhand report (Fr. Stanley Jaki → G. J. Strangfeld → consultation with bishop) of another sun miracle investigator, one “Professor Dr. Stöckl” in Germany, who made a similar experiment: After almost a minute (the time varies according to the condition of the atmopshere and the momentary condition of the eyes) one thinks to see a dark blue disk in front of the sun (this is already a sign of the highly excited state of the retina). According to my experience … this dark blue disk is somewhat smaller than the solar disk, so that the edge of that disk stands out as a ring beyond that dark blue disk. Then one has right away the impression that the solar disk rotates with great speed in one or the other direction. This I have experienced often enough. All this is a subjective appearance that has nothing to do with the external world. These reports are suggestive, but weaker than all but the barest Fatima testimonials. Dr. Messeen admits as much, saying that “I didn’t look at the sun for a sufficiently long time”. Can we find people even more committed - or reckless, or masochistic - than Professors Messeen and Stöckl? Absolutely yes: there was a whole subfield of late 18th / early 19th century psychophysicists who experimented with staring at the sun for long periods, many of whom went blind. Joseph Plateau (1801 - 1883, went blind in 18432) summarizes their work in his aptly-named On The Contemplation Of Bright Objects. He lists twenty-six scientists who tried staring at the sun for a really long time. Most describe what we now recognize as typical retinal afterimages, and Plateau spends most of his time talking about how long these last and what colors they pass through. The only one of Plateau’s sources who reports anything even slightly interesting to us is Robert Darwin (father of Charles; cf. Secrets of the Great Families). After stating that: The author has frequently observed that when he gazed at the midday sun for a long time, until its disk appeared pale blue, he saw a bright blue specter on other objects for more than two days. …he mentions how When looking at the meridian sun as long as the eyes can well bear its brightness, the disc first becomes pale, with a luminous crescent, which seems to librate from one edge of it to the other owing to the unsteadiness of the eye. Here is pallor, and at least a hint of motion. But it’s pretty different from spinning, and not really clear how it relates to the sun miracle. Gustav Fechner (1801 - 1887, went blind in 1839) may have stared for even longer; you can read more of his story - including his ensuing insanity and subsequent attempts to found a new religion - on Adam Mastroianni’s blog. But all that he records about his ill-fated experiment is that: …after looking at the sun through homogeneously colored lenses, if you close your eyes, the primary impression remains for a long time and the entire afterimage usually disappears without a complementary coloration having clearly emerged. These people are great, and they all sound like minor Sam Kriss characters. But after whole careers dedicated to staring at the sun much longer than any normal person would ever try, they report only the barest hints of odd phenomena. Indeed, if anything they saw less of interest to the Fatimologist than Profs. Messeen and Stöckl. Worse, all of these authorities saw their phenomena after seconds to minutes of deliberate staring. Surely if it had taken a minute of staring at the sun before anything happened, some of our eyewitnesses would have mentioned this; after all, several mention that they were starting to doubt after the child-seers’ deadline had passed a few minutes earlier. But by all accounts, the miracle was near-instantaneous. Although Messeen and Stöckl’s reports of miracle-like phenomena are intriguing, it doesn’t seem like they can be the whole picture. Let’s move on. 2.2: Aurora Borealis? At This Time Of Year? In This Part Of The Country? Localized Entirely Within Your Kitchen? Could the miracle at Fatima have been some kind of weird weather phenomenon? The main argument against is that if it were a common weather phenomenon, it would not have awed and terrified tens of thousands of people. But if it were a rare weather phenomenon, then the seers’ successful prophecy that the rare weather phenomenon would happen at solar noon on October 13 1917 becomes almost as impressive as an outright miracle. The argument in favor is that dozens of people have written books and papers about this possibility, we would feel remiss if we didn’t mention them, and anyway it gives us the opportunity to look at pretty pictures of interesting weather phenomena. This is a sun dog. It’s caused by ice crystals in the upper atmosphere that refract sunlight in a very specific way. It’s very cool, but aside from a resemblance to a wheel, it looks nothing like the miracle of Fatima. A sun dog doesn’t have any unusual colors, it doesn’t change size, and it doesn’t spin (I’ve embedded a YouTube video not because a still image would be misleading - it wouldn’t be - but just in case you want to see for yourself how completely motionless it is). It’s just a halo shape with two smaller illusory suns on either side of the real one - something which no one at Fatima reported. (source) This is a solar corona3; cloud iridescence is a related phenomenon. I don’t know how much work the exposure length is doing in this particular photo, but I’m guessing more than zero. Coronae are also very pretty, and might explain the description of wheels and colors. They seem surprisingly common for something that I can’t ever remember seeing, supposedly happening several times a year in most locations. But they don’t spin, the colors don’t change or stain the surrounding landscape, and they don’t fall to earth and crush people. Let’s keep this one as a backup option and move on. This is a dust storm. Steuart Campbell wrote a paper arguing that the miracle was caused by one of these, and I admit if I saw this I would start praying pretty hard. Dust storms can change the color of the sun (including unusual colors like green or blue). And very, very charitably, whirling dust could look like the sun itself spinning around, and the thickening and thinning of dust could look like the sun approaching or receding. But this would require a dust storm localized to a 20 mile region of Portugal which does not, technically, have any dust (and where it was, technically, raining at the time). Campbell proposes that perhaps a storm blew a 20 miles x 20 mile dust cloud from the Sahara out to the Atlantic, then onto Fatima for ten minutes during a break in the rain, then back to the Atlantic again. But I don’t think any dust storm has ever behaved in quite this way. If it did, it probably wouldn’t be at the exact moment predicted by child-seers months in advance. At this point, we might as well talk about literal meteors. The way I’m imagining it is this: as a meteor approaches Earth, it breaks up into three big parts and a host of smaller particles. They strike the atmosphere head-on, from the approximate direction of the sun. The small particles hit first and make a firework show. Then the three big pieces hit, producing multicolored fireballs (meteors can absolutely stain the sky bright colors - see the video). Finally, they burn out a few miles above the ground, , convincingly producing the appearance of the sun falling to earth and nearly striking the spectators. This could even explain the warmth and dry clothes - a local meteor strike produces a lot of heat! I like this because it’s the only one that takes seriously the facet of the event which most impressed the witnesses - the part where it looked like the sun was plummeting to earth and about to kill them. But against it: would a rain of micrometeorites really look like the sun was “dancing”, “spinning”, or “zig-zagging”? Aren’t most nearby meteor strikes very loud? (the Fatima event was, according to witnesses, silent) Don’t they usually break windows? Aren’t most meteor strikes of this size visible for hundreds of miles, not just the twenty miles from which we have witness testimonies? Wouldn’t the strike have to be remarkably head-on, and remarkable close to the position of the sun, in order to look like a solar phenomenon rather than a long streak? Aren’t most meteor fireballs visible for between a few seconds and a minute, not the ten minutes of the Fatima event4? And if there were some extremely unusual meteor strike that was the exception to everything, wouldn’t it still be pretty surprising for it to happen at the exact time and place predicted by child-seers months in advance? We come to the unpromisingly-titled Derivation of equations of the model of the dynamic behavior of the three-dimensional atmospheric cloud of electrically charged ice crystals under the influence of electrostatic forces, in which Artur Wiroski argues that Fatima was a three-dimensional atmospheric cloud of electrically charged ice crystals under the influence of electrostatic forces. Actually, he offhandedly mentions Fatima in three sentences, with the majority of the paper looking more like the image above - but he eventually makes it into a Guardian article where he emphasizes that yes, he is trying to explain the miracle of the sun. However, if I’m understanding him correctly, he says that his theoretical ice crystal phenomenon can only happen when the sun is at an altitude below 22 degrees. But during the Fatima miracle, the sun was at 42 degrees (and Dalleur’s mysterious light source was at 30 degrees), so none of this applies. I’ve tried to include pictures of all the phenomena I mention in this section. I failed for this one, because it’s never been spotted or photographed. It’s just some incredibly weird thing that one scientist says ice crystals might do if parameters were ever exactly right, with such a precise definition of “exactly right” that it’s never happened in real life. If it ever did happen, it probably wouldn’t be at exactly the moment predicted by child-seers several months in advance. 2.3: Everyone’s Mad Here Except You And Me Another common response calls the Sun Miracle a “mass hallucination”. Can 70,000 people really hallucinate the same thing? “Mass hallucination” on Wikipedia redirects to List Of Mass Panic Cases. The Miracle of the Sun is on there, but listed as “(disputed)” - the only item to earn such a parenthetical. The other fifty items mostly belong to three categories: A disease with unusual symptoms spreads through a population; doctors eventually pronounce it psychosomatic.

Interlude: The Anti-Clerical Union As mentioned briefly before, 1910s Portugal was in a period of transition. In 1910, a group of proto-socialist revolutionaries overthrew the monarchy. The monarchy and church had been in cahoots, so the revolutionaries cracked down on Catholicism, closing the monasteries and persecuting the churches. This was a bold move - only an upper crust of educated urbanites were proto-socialist, and 99%+ of the country identified as Catholic, albeit at various levels of religiosity. In the 1920s, conservatives would regain the upper hand, overthrow the proto-socialists and restore a pro-church dictatorship. Still, the small urban educated ruling class of 1910s Portugal was a hotbed of atheistic anti-church sentiment. Probably the child-seers of Fatima were only dimly aware of this, but their prophecies were a spark entering a powder keg, and many of the more worldly witnesses were aware of this context. While reading through Fatima-related documents, I came across some pamphlets by Grupo Anticlerical, one of the era’s leading atheist organizations. They are totally irrelevant to our primary goal of trying to figure out what’s up with the miracle. But I love them so much that I can’t resist adding one as an interlude. I have slightly edited the machine translation for clarity and readability: To defend the sacred freedom of conscience—guaranteed by the original Law of Separation of Church and State—from the furious attacks of implacable Jesuitism—the greatest enemy of all human happiness!—the Anticlerical Group was organized in this town, similar to what is being done in many parts of the country! This was necessary. They call us to fight. We present ourselves courageously! The great, formidable battle of progress against Ultramontane Reaction, of Freedom against Tyranny, of Truth against Lies is waged again with enthusiasm and ardor! The redemptive dawn that the Portuguese people saw emerge on October 5, 1910, is about to be eclipsed, intercepted by the immense flood of black cassocks!... But in the dark night that seeks to envelop Reason; where moral suffering takes on tragic proportions in a frightening asphyxiation, the Light will once again break through!... the consoling light of elevated spirits... and like a sinister scarecrow, the grim reaction will flee in terror! Liberal people! Hear us! This fight is terrible! Many of our people will perhaps be crushed and tortured on the battlefield, but what does it matter?! Every war against reaction is a holy war because it frees consciences from the clutches of their enemies!... It is the fight of Justice against Iniquity, of Love against Hate, of Good against Evil!... To the fight, then, for the Progress that makes life beautiful; for the Freedom that redeems the people; and for the science that guides us all as an eternal beacon to the Light of Truth! Gago Coutinho and Sacadura Cabral [two Portuguese aviators who had recently flown across the Atlantic] are prodigious spirits before whom our souls kneel religiously – boldly breaking through the air with the mathematical certainty of someone who knows the path to be taken to get from one point to another determined point; flying through the immense blue as sure of their route as any of us walking on earth, they showed us that Science is not an empty word! The power of their prodigious sextant, the fruit of immense scientific lucubrations, is more real and positive than the cross of Christ painted on their device, which could not even have saved them from falling due to lack of gasoline in the middle of the sea at the mercy of the waves. Their extraordinary journey, an adventure which moved us to tears, was the most resounding scientific victory of recent times! It was, above all, a powerful affirmation of science! Let us therefore make science our religion, for scientific religion is Freedom of Thought! To be a Free Thinker is to love immortal science, eagerly waiting for it to reveal to us the truth of the great enigmas of the Universe! And only it can reveal them! People! Let us always fight! From the victory of progress, science, freedom, and free thought, will result human happiness, joy, love, fraternity, respect for women, veneration for mothers, adoration for children, affection for the elderly, protection for the sick, the unfortunate, the tortured. The victory of reaction, of clericalism, of black, cruel and ferocious Jesuitism will result in: the gallows, the acts of faith with their human destruction, persecution, exile, robbery, arson, the deflowering of women, the killing of children, the monstrous torture of all free spirits! The history of so many crimes committed in the name of God horrifies us! The Inquisition, relentlessly slaughtering, tearing, and burning the flesh of so many victims, is still today, in the twentieth century, a sinister specter haunting us!... O most holy mothers! O holy, pious mothers who so love your sweet little children! Have compassion on your beautiful little children, sacred fruits of your blessed wombs: Love Freedom! Love Liberty, O loving mothers, immaculate saints of our altar! We pray for them... for your children, who are the light of your candid eyes, the life of your life... for little children... for all children, tender rosebuds that retrogression furiously lashes, – love Liberty!. And you, O parents! Heads of families who so tremble at your loved ones, snatch them from the merciless clutches of the reactionaries who twist their brains and kill their reason! Hear us all, men, women, and children; listen: Freedom writhes in horrible convulsions... it vibrates in space, echoing from mountain to mountain, an anguished cry for help!... It is Freedom that falls, annihilated! It is Freedom that dies in the bloody clutches of Jesuitism! The Miracle of Fatima, people, is a ridiculous lie, it is a comedy, it is not religion! Come on, liberals! Let us all rise up from this criminal apathy and, without delay, fight not the religious sentiment of the Portuguese people, such a good people, a race of heroes, but rather the exploitation that clericalism is inflicting on the people, foisting upon them, at a good price, images of the saint —trademarked to avoid competition from other vampires! —the shamelessness!—and leading them, through suggestion, to wallow and drink madly, the miraculous water, foul, filthy water, full of rot, pus, and pestilent microbes that the sore flesh of the sick leaves deposited there in the washings! We, all as one man, will fight the reaction, forcing it to retreat and thus, with our efforts, we will save the Republic and the Portuguese Land from its fatal annihilation! … …anyway, Interlude over, let’s get back to the miracle. 2: The Skeptical Explanations Re-invigorated by the rousing prose of Grupo Anticlerical, can we come up with a materialist explanation for the sun miracle? 2.1: Pilgrim, Avert Thine Eyes Starting in October 1917, doubters have focused on one obvious possibility: staring at the sun is harmful to your health. If you stare too long, you go blind. If you stare just slightly less long than that . . . maybe something strange happens? Just to get a particular theory out there: everyone knows that if you stare at a bright light source for a few seconds, you get a temporary afterimage - often pink or bluish-green - on your retina. Suppose the pilgrims stared at the sun. Their eyes would inevitably make microsaccades - small natural jerking motions - and the afterimage would appear somewhere slightly different than the true sun. This might look like the sun turning pink or blue and moving in a zig-zag pattern. Believers in the miracle counter this proposal in several ways. First, although it might explain the sun changing colors and dancing, it doesn’t give an explanation for spinning, sparkling, or falling to earth and threatening to crush everybody (exactly three times in a ten minute interval, no less). Second, although witnesses describe the sun changing color, they also describe everything around them changing color to match the sunlight, which doesn’t match localized afterimages. And one scientifically-minded witness specifically describes closing his eyes to see if there was a persistent afterimage; he says there was not. Third, there are no reports of eye injuries or blindness from a crowd that was, supposedly, staring straight at the sun for ten minutes. This is a good match to witness reports (that the sun was unusually pale and didn’t hurt to look at) and with Dalleur’s theory (that it wasn’t the sun). But it’s a bad match to any theory depending on eye injuries. Fourth, this would require Portuguese people to be total idiots. Everyone already knows bright lights cause afterimages. Surely if you stare at the sun for ten minutes and get some afterimages, you’re not going to freak out and start screaming about miracles and the end of the world. Even if the peasants had somehow remained ignorant of afterimages their whole lives, the scientists and doctors in attendance wouldn’t be fooled. If we are to keep this theory, maybe we should posit some retinal phenomenon much stronger than the ones we know. Everyone thinks they know how much an illusion can fool you - “yeah, okay, obviously the cookie that looks very slightly bigger will actually be the same size” - which is exactly why the really good ones, like the Checker Shadow Illusion, come as such a shock. Squares A and B are the same color. Source: Checker shadow illusion. There’s no way around it: we need to hear from someone who has stared directly into the sun. August Meessen was a physics professor at a Catholic university, which sounds like exactly the job profile we want for this sort of thing. He found himself sufficiently interested in the Fatima miracle to stare straight into the sun for a few minutes and record what happened. From his paper: In November 2002, I looked directly into the sun, at about 4 p.m. The sun was relatively low above the horizon and its light intensity was attenuated, although the sky was clear. I was able to look right into the sun and was amazed to see that the sun was immediately converted into a grey disc, surrounded by a brilliant ring. The grey disc was practically uniform, while the surrounding ring was somewhat irregular and flamboyant, but did not extend beyond the solar disk. It coincided with its rim. I stopped the experiment, since I wanted to be prudent, but I had experienced myself the initial phase of a typical “miracle of the sun” and I could explain it. The sun became grey, since my eyes immediately responded to its great luminosity by an automatic reduction of their sensitivity. This adaptation is not simply due to the bleaching of pigments in the colour-sensitive cones of the fovea, where the image of the sun is projected, but to secondary processes. By “initial phase”, he means the part where the sun looks pale and well-defined, like a full moon. This isn’t something I think needs explanation (see above), but he sure has explained it. Moving on: In a second experiment, realized at 3 p.m. in December 2002, I looked straight at the sun during a much longer time. After some minutes, I saw impressive colours, up to 2 or 3 times the diameter of the sun. They changed, but were mainly pink, deep blue, red and green. Further away, the sky became progressively more luminous. I stopped there, since I understood that these colours resulted from the fact that the red, green and blue sensitive pigments are bleached and regenerated at different rates. This is frustratingly vague. Are the “impressive colors up to 2-3 times the diameter of the sun” just the normal aftereffects of staring at a bright object? Or something surprising even to physics professors? And the spinning? What about the motions of the sun? I didn’t see them, because I didn’t look at the sun for a sufficiently long time or my brain knew already too much. Once, after I had been looking at a very long passing train, I had (for about 30 seconds) the illusion of an opposite motion. Joseph Plateau discovered that when we look at the centre of a spiral that is rotating at some given velocity about this point, and when we stop this rotation, we see a reversed rotation. It lasts for several minutes, although in reality, there is no motion at all. This is a good example of motional after-effects. The “dance of the sun” is initiated, however, by a spontaneous generation of apparent motion. This feels suspiciously like a just-so story. His explanation for the sun falling to earth to crush everyone - which he also did not see - is equally ad hoc: A very interesting study was recently devoted to this “zoom and loom effect”. It tends to appear when the brain is confronted with the two-dimensional retinal image of an object that is situated at some unknown distance. The brain will then consider the possibility that it could come closer, by performing an illusory mental zoom, where the apparent size of the object is progressively increased. This results from the fact that evolution preserved the tendency to take into account the possibility of a dangerous approach: a rapid evasive action could be beneficial for survival. If true, it sounds like you should be able to generate this effect not just by staring at the sun (ill-advised, causes blindness), but by staring at the moon. I would like to test this, but unfortunately I am writing this on the night of a new moon; I’ll check back in two weeks. Still, I am skeptical that no human being living before 1917 AD ever figured out that staring at a celestial body long enough would make it appear to fall to earth and crush you. Compare to much gentler illusions - like how the moon looks bigger right when it starts to rise - which everybody knows about. I was able to find a thirdhand report (Fr. Stanley Jaki → G. J. Strangfeld → consultation with bishop) of another sun miracle investigator, one “Professor Dr. Stöckl” in Germany, who made a similar experiment: After almost a minute (the time varies according to the condition of the atmopshere and the momentary condition of the eyes) one thinks to see a dark blue disk in front of the sun (this is already a sign of the highly excited state of the retina). According to my experience … this dark blue disk is somewhat smaller than the solar disk, so that the edge of that disk stands out as a ring beyond that dark blue disk. Then one has right away the impression that the solar disk rotates with great speed in one or the other direction. This I have experienced often enough. All this is a subjective appearance that has nothing to do with the external world. These reports are suggestive, but weaker than all but the barest Fatima testimonials. Dr. Messeen admits as much, saying that “I didn’t look at the sun for a sufficiently long time”. Can we find people even more committed - or reckless, or masochistic - than Professors Messeen and Stöckl? Absolutely yes: there was a whole subfield of late 18th / early 19th century psychophysicists who experimented with staring at the sun for long periods, many of whom went blind. Joseph Plateau (1801 - 1883, went blind in 18432) summarizes their work in his aptly-named On The Contemplation Of Bright Objects. He lists twenty-six scientists who tried staring at the sun for a really long time. Most describe what we now recognize as typical retinal afterimages, and Plateau spends most of his time talking about how long these last and what colors they pass through. The only one of Plateau’s sources who reports anything even slightly interesting to us is Robert Darwin (father of Charles; cf. Secrets of the Great Families). After stating that: The author has frequently observed that when he gazed at the midday sun for a long time, until its disk appeared pale blue, he saw a bright blue specter on other objects for more than two days. …he mentions how When looking at the meridian sun as long as the eyes can well bear its brightness, the disc first becomes pale, with a luminous crescent, which seems to librate from one edge of it to the other owing to the unsteadiness of the eye. Here is pallor, and at least a hint of motion. But it’s pretty different from spinning, and not really clear how it relates to the sun miracle. Gustav Fechner (1801 - 1887, went blind in 1839) may have stared for even longer; you can read more of his story - including his ensuing insanity and subsequent attempts to found a new religion - on Adam Mastroianni’s blog. But all that he records about his ill-fated experiment is that: …after looking at the sun through homogeneously colored lenses, if you close your eyes, the primary impression remains for a long time and the entire afterimage usually disappears without a complementary coloration having clearly emerged. These people are great, and they all sound like minor Sam Kriss characters. But after whole careers dedicated to staring at the sun much longer than any normal person would ever try, they report only the barest hints of odd phenomena. Indeed, if anything they saw less of interest to the Fatimologist than Profs. Messeen and Stöckl. Worse, all of these authorities saw their phenomena after seconds to minutes of deliberate staring. Surely if it had taken a minute of staring at the sun before anything happened, some of our eyewitnesses would have mentioned this; after all, several mention that they were starting to doubt after the child-seers’ deadline had passed a few minutes earlier. But by all accounts, the miracle was near-instantaneous. Although Messeen and Stöckl’s reports of miracle-like phenomena are intriguing, it doesn’t seem like they can be the whole picture. Let’s move on. 2.2: Aurora Borealis? At This Time Of Year? In This Part Of The Country? Localized Entirely Within Your Kitchen? Could the miracle at Fatima have been some kind of weird weather phenomenon? The main argument against is that if it were a common weather phenomenon, it would not have awed and terrified tens of thousands of people. But if it were a rare weather phenomenon, then the seers’ successful prophecy that the rare weather phenomenon would happen at solar noon on October 13 1917 becomes almost as impressive as an outright miracle. The argument in favor is that dozens of people have written books and papers about this possibility, we would feel remiss if we didn’t mention them, and anyway it gives us the opportunity to look at pretty pictures of interesting weather phenomena. This is a sun dog. It’s caused by ice crystals in the upper atmosphere that refract sunlight in a very specific way. It’s very cool, but aside from a resemblance to a wheel, it looks nothing like the miracle of Fatima. A sun dog doesn’t have any unusual colors, it doesn’t change size, and it doesn’t spin (I’ve embedded a YouTube video not because a still image would be misleading - it wouldn’t be - but just in case you want to see for yourself how completely motionless it is). It’s just a halo shape with two smaller illusory suns on either side of the real one - something which no one at Fatima reported. (source) This is a solar corona3; cloud iridescence is a related phenomenon. I don’t know how much work the exposure length is doing in this particular photo, but I’m guessing more than zero. Coronae are also very pretty, and might explain the description of wheels and colors. They seem surprisingly common for something that I can’t ever remember seeing, supposedly happening several times a year in most locations. But they don’t spin, the colors don’t change or stain the surrounding landscape, and they don’t fall to earth and crush people. Let’s keep this one as a backup option and move on. This is a dust storm. Steuart Campbell wrote a paper arguing that the miracle was caused by one of these, and I admit if I saw this I would start praying pretty hard. Dust storms can change the color of the sun (including unusual colors like green or blue). And very, very charitably, whirling dust could look like the sun itself spinning around, and the thickening and thinning of dust could look like the sun approaching or receding. But this would require a dust storm localized to a 20 mile region of Portugal which does not, technically, have any dust (and where it was, technically, raining at the time). Campbell proposes that perhaps a storm blew a 20 miles x 20 mile dust cloud from the Sahara out to the Atlantic, then onto Fatima for ten minutes during a break in the rain, then back to the Atlantic again. But I don’t think any dust storm has ever behaved in quite this way. If it did, it probably wouldn’t be at the exact moment predicted by child-seers months in advance. At this point, we might as well talk about literal meteors. The way I’m imagining it is this: as a meteor approaches Earth, it breaks up into three big parts and a host of smaller particles. They strike the atmosphere head-on, from the approximate direction of the sun. The small particles hit first and make a firework show. Then the three big pieces hit, producing multicolored fireballs (meteors can absolutely stain the sky bright colors - see the video). Finally, they burn out a few miles above the ground, , convincingly producing the appearance of the sun falling to earth and nearly striking the spectators. This could even explain the warmth and dry clothes - a local meteor strike produces a lot of heat! I like this because it’s the only one that takes seriously the facet of the event which most impressed the witnesses - the part where it looked like the sun was plummeting to earth and about to kill them. But against it: would a rain of micrometeorites really look like the sun was “dancing”, “spinning”, or “zig-zagging”? Aren’t most nearby meteor strikes very loud? (the Fatima event was, according to witnesses, silent) Don’t they usually break windows? Aren’t most meteor strikes of this size visible for hundreds of miles, not just the twenty miles from which we have witness testimonies? Wouldn’t the strike have to be remarkably head-on, and remarkable close to the position of the sun, in order to look like a solar phenomenon rather than a long streak? Aren’t most meteor fireballs visible for between a few seconds and a minute, not the ten minutes of the Fatima event4? And if there were some extremely unusual meteor strike that was the exception to everything, wouldn’t it still be pretty surprising for it to happen at the exact time and place predicted by child-seers months in advance? We come to the unpromisingly-titled Derivation of equations of the model of the dynamic behavior of the three-dimensional atmospheric cloud of electrically charged ice crystals under the influence of electrostatic forces, in which Artur Wiroski argues that Fatima was a three-dimensional atmospheric cloud of electrically charged ice crystals under the influence of electrostatic forces. Actually, he offhandedly mentions Fatima in three sentences, with the majority of the paper looking more like the image above - but he eventually makes it into a Guardian article where he emphasizes that yes, he is trying to explain the miracle of the sun. However, if I’m understanding him correctly, he says that his theoretical ice crystal phenomenon can only happen when the sun is at an altitude below 22 degrees. But during the Fatima miracle, the sun was at 42 degrees (and Dalleur’s mysterious light source was at 30 degrees), so none of this applies. I’ve tried to include pictures of all the phenomena I mention in this section. I failed for this one, because it’s never been spotted or photographed. It’s just some incredibly weird thing that one scientist says ice crystals might do if parameters were ever exactly right, with such a precise definition of “exactly right” that it’s never happened in real life. If it ever did happen, it probably wouldn’t be at exactly the moment predicted by child-seers several months in advance. 2.3: Everyone’s Mad Here Except You And Me Another common response calls the Sun Miracle a “mass hallucination”. Can 70,000 people really hallucinate the same thing? “Mass hallucination” on Wikipedia redirects to List Of Mass Panic Cases. The Miracle of the Sun is on there, but listed as “(disputed)” - the only item to earn such a parenthetical. The other fifty items mostly belong to three categories: A disease with unusual symptoms spreads through a population; doctors eventually pronounce it psychosomatic.

It’s the red line on this chart; if you can’t see a red line at your screen resolution, then you’ve learned something important about the the EU tech sector. 37: Seen on @cremieuxrecuel’s twitter (preliminary, needs replication): Jews may have gone from 65-29 Democrat/Republican in 2020 to 58-40 this election. 38: Extelligence has a post responding to my critique of the cultural Christianity argument (among, uh, many other things), but I don’t really think it connects. I’m not telling atheists they can’t go to church/synagogue if it makes them feel happy and fulfilled - I’ve done this myself sometimes. My post was meant to argue against the claim that, for pragmatic reasons, atheists should support the Christianization of society as a defense against Islam or postmodernism or some other philosophical enemy. 39: Related: Extelligence is finally going for their Trust Assembly project/idea/startup for online consensus-based truth-seeking (I think something like a cross between Community Notes and Wikipedia, but as a browser extension, and for everything). He’s looking for potential developers/testers/users. 40: Jiankui He is the Chinese geneticist who made history with the first germline gene editing in humans (resulting in three babies supposedly immune to AIDS, although nobody has tested this). China sentenced him to three years in prison for unauthorized experimentation, but now he’s out of jail, has an English-language Twitter account, has a new lab, wants to work on Alzheimers, and seems pretty based (although not infinitely based): 41: Anthropic has a new version of their AI Claude which can use your computer. You give it permission, put it on a virtual desktop, and ask it to do things for you (eg “please find and download a picture of a cat” or “please research these ten things and put them in a text file”.) It moves your cursor, browses the Internet, and creates and saves files. People keep saying they’ll care about AI “when it operates autonomously” or “when it becomes an agent”. But this is a trivial barrier, and one which Computer Use Claude has arguably already passed. So far this feature is limited to developers (though anyone with computer knowledge can sign up for it) but I expect it to be the near future of consumer AI, to get better quickly, and to shade gradually into the “autonomous” “agentic” AI that you all think will require a paradigm shift. 42: Claim (from the IDF): Hamas faked polls showing that most Palestinians supported the October 7 attack; the real numbers are 31% in favor, 64% against. 43: Otto von Bismarck wanted to trick France into declaring war on Germany. In order to provoke the French, he sent the Ems Dispatch, a statement describing recent diplomatic events in a way that sounded maximally offensive. The French were so offended that “crowds” in Paris demanded war, and the Franco-Prussian War was declared soon afterwards. The part of this that I find most interesting is the text of the dispatch itself, which read: After the news of the renunciation of the Prince von Hohenzollern had been communicated to the Imperial French government by the Royal Spanish government, the French Ambassador in Ems made a further demand on His Majesty the King that he should authorize him to telegraph to Paris that His Majesty the King undertook for all time never again to give his assent should the Hohenzollerns once more take up their candidature. His Majesty the King thereupon refused to receive the Ambassador again and had the latter informed by the Adjutant of the day that His Majesty had no further communication to make to the Ambassador. I’m fascinated by the idea that only 150 years ago, it was obvious that if someone sent you this statement, you had to declare war or abandon all honor. If I read it carefully, I can sort of parse out that it sounds like the Prussians are unhappy, but that’s the most emotion I gather from it. Anyway, the Franco-Prussian War led to World War I which led to World War II - so if you don’t like 50 million people dying and the total devastation of Europe, blame this statement about ambassadors. 44: The first use of artificial insemination in humans: The first recorded case of artificial insemination by donor didn’t occur until 1884, when Dr. William Pancoast decided to treat a couple’s infertility by secretly inseminating the woman with sperm obtained from a medical student. The insemination happened while the patient was under anesthesia and Dr. Pancoast did not tell her what had occurred. She gave birth to a baby boy nine months later, but it was several years before the doctor finally confessed to her husband what he had done. Neither man ever informed the mother. It was 25 years later the result of this case was published. Dr. Pancoast was roundly condemned for his actions, but it did open the door for consensual sperm donor insemination. 45: ClearerThinking administers several personality tests to the same people to learn more about their comparative accuracy. I am most interested in their finding that tests with “factors” (eg the Big Five, where you rate people on a numeric scale) are inherently more accurate than those with “types” (eg Myers-Briggs, where you assign someone a specific category) and that, adjusting for this, Big Five is no more predictive than the Enneagram: 46: In 2022, I wrote Whither Tartaria, where I asked why ornate classical styles switched to more austere modernist styles around 1900 - 1950 in a variety of different arts (painting, architecture, literature, poetry, etc). I proposed seven theories, but was unsure which if any were true. Since then, Samuel Hughes of Works In Progress has been investigating. In May, he wrote a well-researched article showing that it wasn’t just increasing cost, because ornate classical architecture now costs less than ever. Now in a new article he demolishes a different theory - it’s not just decreasing cost (and subsequent lack of ability to signal wealth) - because costs didn’t decrease in several other arts, and the change was led by artists with rich people as reluctant followers. He concludes: Modernism may well be a status game of some kind; it may well signal taste more than it signals wealth; and this latter feature may be one of the things that distinguishes it from older artistic styles. But the mechanism by which this change came about must be different to the one Alexander describes. 47: Sort of kind of related - When Hamilton Lost Its Snob Appeal. The musical Hamilton was briefly an artistic/cultural phenomenon, but tastemakers eventually switched to making fun of it. Why? Rob Henderson says it happened after ticket prices came down and the common people could enjoy it. I disagree: everyone I knew who was into Hamilton got into it from the free online soundtrack long before they’d seen the show; I think this is more likely the usual fad cycle where anybody who’s too into yesterday’s fad is behind the curve and therefore uncool. 48: Related: Why are people such jerks to public intellectuals? And more. I agree this is a great mystery. 49: Some prominent Substack psychiatrists doing a video Q&A, submit your questions here. 50: Naomi Kanakia: The Literacy Delusion had a number of explanations for why reading books seemed to be so much worse for human beings (in terms of emotional wellness and productivity) than other forms of narrative entertainment, but its main theory was the integration hypothesis. That the stream of words in a book trained the human brain into a habit of self-consciousness, that reading books forced human beings to think of themselves as a stream of text, processed through time, making a coherent argument of some sort. And that this overall flattening effect forced readers to ignore aspects of their personality or their situation that were not otherwise in line with the overarching story they'd created about themselves. Basically, reading books causes repression and neurosis. The Literacy Delusion argued that, yes, human beings are storytelling machines, but that a stream of written text is a particular kind of story—a story that is particularly flat, particularly devoid of conflicting or harmonizing information—and that this flatness creates a peculiar effect on the human brain. 51: Last month, I linked Sasha Gusev’s No, Intelligence Is Not Like Height and asked people who disagreed to share their arguments; they sure did. First, several people pointed me to a new preprint, Family-GWAS Reveals Effects Of Environment And Mating On Genetic Associations, which finds that one of the main papers Gusev cited to make his case, Howe 2022, made a mistake - imputing sibling genotypes using a process designed for non-sibling genotypes - and that once that mistake is corrected, the finding disappears and intelligence and height appear similar. Second, Joseph Bronski has a more specific post where he responds to Gusev’s points one by one. He accuses Gusev of “[making] up his own chart to remove the error bars [from the originals], to obscure the fact that the study found no evidence for this in IQ”, and says that the cases where he didn’t do that are just “population stratification and range restriction”. Third, Noah Carl at Aporia, instead of writing a direct response like Bronski, argues that the usual method of attacking twin studies is obsolete; not only have the most-debated assumptions behind twin studies been thoroughly validated, but there are now other lines of evidence besides twin studies which confirm high IQ heritability. Fourth, Leonardo Parro (not framed as a response to Gusev) goes into more depth about one of those ways, a “pedigree-based analysis” demonstrating heritability of 54 - 69%, ie no “missing heritability” compared to twin studies. He summarizes this as the effect of “rare variants” compared to the usual SNPs - ie if you only look at the most common genes that are easiest to find, you get “missing heritability” compared to twin studies, but if you widen your search to rare genes that are hard to find, you don’t. 52: Extremely related: Heliospect is a startup promising polygenic selection for IQ and other traits; they were trying to stay in stealth mode but The Guardian spied on them and nonconsensually revealed their existence. The discussion on the r/ssc subreddit centered on their claim that (given enough embryos to choose from) they could increase a baby’s expected IQ by 6 points (I’ve also heard 7.5). Sasha Gusev had previously argued that current technology maxed out at 3.5 and future technology would max out at 6, so a claim of 6 - 7.5 is pretty extreme; Gwern, who wrote the pioneering analysis of this technology, was also skeptical. But Heliospect says they’ve got better predictors than academia that use the rare variants everyone else misses; after talking to the company, Gwern retracted his objections and says he finds their claim “pretty plausible”. Local ACX commenter geneticist Gene Smith also redid some calculations, changed his mind, and says “probably pretty realistic”. I find this interesting not just because of the polygenic selection angle, but because if Heliospect is right then their predictor is able to predict more genetic IQ than the “missing heritability” people believe exists, and it should be able to put this argument to bed once and for all. 53: This month in censorship: X/Twitter banned journalist Ken Klippenstein for sharing the Trump campaign’s dossier on JD Vance. Twitter’s side of the story is that the dossier was probably originally stolen by Iranian agents and they don’t want to support that kind of thing by letting people signal-boost the illicitly obtained goods; you can read Klippenstein’s side here. He appears to be unbanned now.

In the early 1990s, as the Soviet Union was collapsing, performance artist Sergey Kuryokhin presented a Daily Show style segment on a Russian talk show. He argued that Vladimir Lenin ate so many mushrooms that he eventually turned into a mushroom, and led the October Revolution while possessed by a sentient mushroom spirit.

There’s one last disadvantage I’m having trouble putting into words, but which I think is the most important. A narrative of helpers and saviors allows saints. It allows people who are genuinely good, above and beyond expectations, who rightly serve as ideals and role models for others. A narrative of justice allows, at best, non-criminals - people who haven’t broken any of the rules yet, who don’t suck quite as much as everyone else. You either stand condemned, or you’re okay so far. If it has any real role models, it’s the cop who wins Officer Of The Year, the guy who’s more sensitive to violations and more efficient in punishment than anyone else. Turn this guy into your moral model, and you’ve got, well, the planet of cops.

#56: Aella Wants To Start A Dating Site Like Old OKCupid Hi it's Aella! I have a concrete thing i want funding for now - rationalist-targeted dating app. there's a few in the works but none hit the really specific spot I want. my proposal is to rebuild a version of old-okcupid (match scores from questions, user profiles, basic messaging, high control over search, strong orientation towards compatibility and personality), and include personality tests/results (women like this, would get women on the app and we should have plentiful data to do this). I also want to structure the questions awesomely, in clear, unambiguous ways that translate to both efficient matching and also good data for us on the back end. I think this would also be a great way to do research, where it would generate a huge amount of data that hopefully spans across a ton of different questions. I'd like to make some very anonymized version of the data publicly available. My goal is to have it be just profitable enough to cover its own costs (tho if it ends up being more profitable i won't complain, i'm just not orienting it towards that). I estimate i need between 30k-150k in funding for a basic version depending on how fancy we wanna get/how much programmers wanna get paid. My personal reach is around 750k horny men, which uhh definitely doesn't help the gender ratio *but* if the site is structured such that personality results are easily shared, i think this would be a great organic start to catch the eye of female users.

Green is one of these five studies, and it does superficially find loss aversion. But Fishburn and Kochenberger have done something weird. They argue that “loss” and “gain” aren’t necessarily objective, and usually correspond to “loss relative to some reference frame” (so far, so good). In order to figure out where the reference frame is, they assume that the neutral point is wherever “something unusual happens to the individual’s utility function” (F&K’s words). So they shift the zero point separating losses and gains to wherever the utility function looks most interesting! After doing this, they find “loss aversion”, ie the utility curve changes its slope at the transition between the loss side and the gain side. But since the transition was deliberately shifted to wherever the utility curve changed slope, this is almost tautological. It isn’t quite tautological: it’s interesting that most of the utility curves had a sharp transition zone, and it’s interesting that the transition was in the direction of loss-aversion rather than gain-seeking. But it’s tautological enough to be embarrassing. Still, this is Fishburn and Kochenberger’s embarrassment, not Kahneman and Tversky’s. And Fishburn and Kochenberger included this study in their review alongside several other studies that didn’t do this to the same degree. Kahneman and Tversky just cited the review article. I don’t think citing a review article that does weird things to a study really qualifies as “systematic misrepresentation.” I guess I’m having a hard time figuring out how angry to be, because everything about Fishburn and Kochenberger is terrible. The average study in F&K includes results from 5-10 executives. But the studies are pretty open about the fact that they interviewed more executives than this, threw away the ones who gave boring answers, and just published results from the interesting ones. Then they moved the axes to wherever looked most interesting. Then they used all this to draw sweeping generalizations about human behavior. Then F&K combined five studies that did this into a review article, without protesting any of it. And then K&T cited the review article, again without protesting. I have to imagine that all of this was normal by the standards of the time. I have looked up all these people and they were all esteemed scientists in their own day. And I believe the evidence shows K&T summarized F&K faithfully. Shouldn’t they have avoided citing F&K at all? Seems like the same kind of question as “Shouldn’t Pythagoras have published his theorem in a peer-reviewed journal, instead of moving to Italy, starting a cult, and exposing his thigh at the Olympic Games as part of a scheme to convince people he was the god Apollo?” Yes, but the past was a weird place. As best I can tell, K&T’s citation of G&P agrees with the authors’ own assessment of their results. Their citation of F&K agrees with the reviewers’ assessment and with a charitable reading of most of the studies involved, although those studies are terrible in many ways which are obvious to modern readers. I would urge people interested in the whodunit question to read Kahneman and Tversky’s original paper. I think it paints the picture of a team very interested in their own results and in theory, and citing other people only incidentally, and in accordance with the scientific standards of their time. I don’t feel a need to tar them as “misrepresenters”. III. Okay, But Is Loss Aversion Real? Remember, all that is about the personal deficiencies of Kahneman and Tversky. Realistically there have been hundreds of much better studies on loss aversion in the forty years since they wrote their article, so we should be looking at those. Here Hreha cites Gal & Rucker: The Loss Of Loss Aversion: Will It Loom Larger Than Its Gain? It’s a great 2018 paper that looks at recent evidence and concludes that loss aversion doesn’t exist. But it’s a very specific, interesting type of nonexistence, which I think the Hreha article fails to capture. G&R are happy to admit that in many, many cases, people behave in loss-averse ways, including most of the classic examples given by Kahneman and Tversky. They just think that this is because of other cognitive biases, not a specific cognitive bias called “loss aversion”. They especially emphasize Status Quo Bias and the Endowment Effect. Status Quo Bias is where you prefer inaction to action. Suppose you ask someone “Would you bet on a coin flip, where you get $60 if heads and lose $40 if tails?”. They say no. This deviates from rational expectations, and one way to think of this is loss aversion; the prospect of losing $40 feels “bigger” than the prospect of gaining $60. But another way to think of it is as a bias towards inaction - all else being equal, people prefer not to make bets, and you’d need a higher payoff to overcome their inertia. Endowment Effect is where you value something you already have more than something you don’t. Suppose someone would pay $5 to prevent their coffee mug from being taken away from them, but (in an alternative universe where they lack a coffee mug) would only pay $3 to buy one. You can think of this as loss aversion (the grief of losing a coffee mug feels “bigger” than the joy of gaining one). Or you can think of it as endowment (once you have the coffee mug, it’s yours and you feel like defending it). These are really fine distinctions; I had to read the section a few times before the difference between loss aversion and endowment effect really made sense to me. Kahneman and Tversky just sort of threw all all this stuff out and saw what stuck and didn’t necessarily try super hard to make sure none of the biases they discovered were entirely explainable as combinations of some of the others. G&R think maybe loss aversion is. They do some clever work setting up situations that test loss aversion but not status quo or endowment - for example, offering a risky bet vs. a safer bet. Here they find no evidence for loss aversion as a separate force from the other two biases. Somewhere in this process, they did an experiment where they gave participants a quarter minted in Denver and asked them if they wanted to exchange it for a quarter minted in Philadelphia. 60% of people very reasonably didn’t care, but another 35% had grown attached to their Denver quarter, with only 5% actively seeking the novelty of Philadelphia. Psychology is weird. I understand why some people would summarize this paper as “loss aversion doesn’t exist”. But it’s very different from “power posing doesn’t exist” or “stereotype threat doesn’t exist”, where it was found that the effect people were trying to study just didn’t happen, and all the studies saying it did were because of p-hacking or publication bias or something. People are very often averse to losses. This paper just argues that this isn’t caused by a specific “loss aversion” force. It’s caused by other forces which are not exactly loss aversion. We could compare it to centrifugal force in physics: real, but not fundamental. Also, you can’t use this paper to argue that “behavioral economics is dead”. At best, the paper proves that loss aversion is better explained by other behavioral economic concepts. But you can’t get rid of behavioral econ entirely! The stuff you have to explain is still there! It’s just a question of which parts of behavioral econ you use to explain it. Complicating this even further is Mrkva et al, Loss Aversion Has Moderators, But Reports Of Its Death Are Greatly Exaggerated (h/t Alex Imas, who has a great Twitter thread about this). This is an even newer paper, 2019, which argues that Gal and Rucker are wrong, and loss aversion does have an independent existence as a real force. There are many things to like about this paper. Previous criticisms of loss aversion argue that most experiments are performed on undergrads, who are so poor that even small amounts of money might have unusual emotional meaning. Mrkva collects a sample of thousands of millionaires (!) and demonstrates that they show loss aversion for sums of money as small as $20. On the other hand, I’m not sure they’re quite as careful as G&R at ruling out every other possible bias (although I don’t have a great understanding of where the borders between biases are and I can’t say this for sure). The main point I want to make is that all the scientists in this debate seem smart, thoughtful, and impressive. This isn’t like social priming experiments where one person says a crazy thing, nobody ever replicates it at scale, and as soon as someone tries the whole thing collapses. These have been replicated hundreds of times, with the remaining arguments being complicated semantic and philosophical ones about how to distinguish one theory from a very slightly different theory. If that takes replicating your result on a sample of thousands of millionaires, people will gather a sample of thousands of millionaires and get busy on the replication. Just overall really impressive work. I don’t feel qualified to take a side in the G&R vs. Mkrva debate, but both teams make me really happy that there are smart and careful people considering these questions. And this is just a drop in the bucket. Alex Imas also links Replicating patterns of prospect theory for decision under risk, which says: Though substantial evidence supports prospect theory, many presumed canonical theories have drawn scrutiny for recent replication failures. In response, we directly test the original methods in a multinational study (n = 4,098 participants, 19 countries, 13 languages), adjusting only for current and local currencies while requiring all participants to respond to all items. The results replicated for 94% of items, with some attenuation. Twelve of 13 theoretical contrasts replicated, with 100% replication in some countries. Heterogeneity between countries and intra-individual variation highlight meaningful avenues for future theorizing and applications. We conclude that the empirical foundations for prospect theory replicate beyond any reasonable thresholds. Beyond any reasonable thresholds! IV. Do Nudges Work? or, How Small Is Small? Continuing through the Hreha article: For a number of years, I've been beating the anti-nudge drum. Since 2011, I've been running behavioral experiments in the wild, and have always been struck by how weak nudges tend to be. In my experience, nudges usually fail to have *any* recognizable impact at all. This is supported by a paper that was recently published by a couple of researchers from UC Berkeley. They looked at the results of 126 randomized controlled trials run by two "nudge units" here in the United States. I want you to guess how large of an impact these nudges had on average... 30%? 20%? 10%? 5%? 3%? 1.5%? 1%? 0%? If you said 1.5%, you'd be right (the actual number is 1.4%, but if I had written that out you would have chosen it because of its specificity). According to the academic papers these nudges were based upon, these nudges should have had an average impact of 8.7%. But, as you probably understand by now, behavioral economics is not a particularly trustworthy field. I actually emailed the authors of this paper, and they thought the ~1% effect size of these interventions was something to be applauded—especially if the intervention was cheap & easy. Unfortunately, no intervention is truly cheap or easy. Every single intervention requires, at the very minimum, administrative overhead. If you're going to do something, you need someone (or some system) to implement and keep track of it. If an intervention is only going to get you a 1% improvement, it's probably not even worth it. Uber infamously had a team of behavioral economists working on its product, trying to “nudge” people in the right direction. Relatedly, Uber makes $10 billion in yearly revenue. If they can “nudge” people to spend 1% more, that’s $100 million. That’s not much relative to revenue, but it’s a lot in absolute terms. In particular, it pays the salary of a lot of behavioral economists. If you can hire 10 behavioral economists for $100,000 a year and make $100 million, that’s $99 million in profit. Or what if you’re a government agency, trying to nudge people to do prosocial things? There are about 90 million eligible Americans who haven’t gotten their COVID vaccine, and although some of them are hard-core conspiracy theorists, others are just lazy or nervous or feel safe already. (source) Whoever decided on that grocery gift card scheme was nudging, whether or not they have an economics degree - and apparently they were pretty good at it. If some sort of behavioral econ campaign can convince 1.5% of those 90 million Americans to get their vaccines, that’s 1.4 million more vaccinations and, under reasonable assumptions, maybe a few thousand lives saved. Hreha says that: Every single intervention requires, at the very minimum, administrative overhead. If you're going to do something, you need someone (or some system) to implement and keep track of it. If an intervention is only going to get you a 1% improvement, it's probably not even worth it. This depends on scale! 1% of a small number isn’t worth it! 1% of a big number is very worth it, especially if that big number is a number of lives! A few caveats. First, a small number only matters if it’s real. It’s very easy to get spurious small effects, so much so that any time you see a small effect you should wonder if it’s real. I’m ready to be forgiving here because behavioral economics is so well-replicated and common-sensically true, but I wouldn’t blame anyone who steers clear. Second, Hreha says: To be honest, you can probably use your creativity to brainstorm an idea that will get you a 3-4% minimum gain, no behavioral economics "science" required. Which leads me to the final point I'd like to make: rules and generalizations are overrated. The reason that fields like behavioral economics are so seductive is because they promise people easy, cookie-cutter solutions to complicated problems. Figuring out how to increase sales of your product is hard. You need to figure out which variables are responsible for the lackluster interest. Is the price the issue? Is the product too hard to use? Is the design tacky? Is the sales organization incompetent? Is the refund/return policy lacking? etc. Exploring these questions can take months (or years) of hard work, and there's no guarantee that you'll succeed. If, however, a behavioral economist tells you that there are nudges that will increase your sales by 10%, 20%, or 30% without much effort on your part... Whoa. That's pretty cool. It's salvation. Thus, it's no surprise that governments and companies have spent hundreds of millions of dollars on behavioral "nudge" units. Unfortunately, as we've seen, these nudges are woefully ineffective. Specific problems require specific solutions. They don't require boilerplate solutions based on general principles that someone discovered by studying a bunch of 19 year old college students. However, the social sciences have done a good job of convincing people that general principles are better solutions for problems than creative, situation-specific solutions. In my experience, creative solutions that are tailor-made for the situation at hand *always* perform better than generic solutions based on one study or another. Hreha is a professional in this field, so presumably he’s right. Still, compare to medicine. A thoughtful doctor who tailors treatment to a particular patient sounds better (and is better) than one who says “Depression? Take this one all-purpose depression treatment which is the first thing I saw when I typed ‘depression’ into UpToDate”. But you still need medical journals. Having some idea of general-purpose laws is what gives the people making creative solutions something to build upon. (also, at some point your customers might want to check your creative solution to see whether it actually gives a “3-4% minimum gain, no behavioral economics required”, and that would be at least vaguely study-shaped.) Third, everyone who said nudging had vast effects is still bad and wrong. Many of them were bad and wrong and making fortunes consulting for companies about how to implement the policies they were claiming were super-powerful. This is suspicious and we should lower our opinion of them accordingly. In a previous discussion of growth mindset, I wrote: Imagine I claimed our next-door neighbor was a billionaire oil sheik who kept thousands of boxes of gold and diamonds hidden in his basement. Later we meet the neighbor, and he is the manager of a small bookstore and has a salary 10% above the US average... Should we describe this as “we have confirmed the Wealthy Neighbor Hypothesis, though the effect size was smaller than expected”? Or as “I made up a completely crazy story, and in unrelated news there was an irrelevant deviation from literally-zero in the same space”? All the people talking about oil sheiks deserve to get asked some really uncomfortable questions. And a lot of these will be the most famous researchers - the Dan Arielys of the world - because of course the people who successfully hyped their results a lot are the ones the public knows about. Still, the neighbor seems like a neat guy, and maybe he’ll give you a job at his bookstore. V. Conclusion: Musings On The Identifiable Victim Effect I actually skipped the very beginning of Hreha’s article. I want to come back to it now. It begins: The last few years have been particularly bad for behavioral economics. A number of frequently cited findings have failed to replicate. Here are a couple of high profile examples: The Identifiable Victim Effect (featured in the workbooks I wrote with Dan Ariely and Kristen Berman in 2014)

In this graph, each datapoint represents a month that Scott has been blogging. A typical month will have between 15-20 posts, of which around half will be authored by Scott and half will be ‘authored’ in some way by the Commentariat, which are mostly Open Threads. I’ve averaged by month because certain types of post get much less engagement than others, and so looking at individual posts ended up too noisy to make attractive graphs (the true goal of any honest statistician). The SSC-era is highlighted in blue. You can see that it shows something a bit like a classic sigmoidal adoption curve (but wearing a top hat). Post engagement starts low, before rapidly shooting up in 2014-15. It peaks in April 2016 – which is highlighted in red in this and all subsequent graphs so you can track peak engagement - before dropping back to a steady level of around 400-600 comments per post for the next three years. Notably, the run of posts that most people regard as being the ‘Golden Age’ for Scott’s writing happens much earlier than peak engagement with the comments section. People disagree about where this run of exceptionally good posts in quick succession start and ends, but I think you could safely say it has definitely begun by the time of The Control Group is Out of Control (although I would date it a little earlier, personally) and ends with either The Toxoplasmosa of Rage or Untitled – basically 2014 has a high density of ‘important’ posts.
The user experience of the blog got worse If Scott’s writing did not get worse, perhaps some other element of the blog did, which led to significant disengagement. For example, perhaps the moderation of SSC got more restrictive around this time or an incredibly obnoxious autoplay advert was introduced to the sidebar. We actually know that the Commentariat are quite sensitive to user experience changes, because Scott notes that Open Threads with an announcement get between 2-4x less engagement than those without. This theory seems very strong to me – the UX was one of the major complaints about early-days ACX, and it seems like you can explain the initial Commentariat stagnation and then flourishing for ACX with reference to the UX specifically. For example, Vladimir writes: My personal theory is that the ACX website itself is less enjoyable. SSC had it's personal charms: I had to pinch and zoom slightly to read the small text better on my phone, and the blue decorations were comforting, and the comments felt like early internet forums for some reason. Now, everything feels more bland. And DinoNerd writes: Personally, I find the ACX experience less good than that of SSC, but I can't disentangle how much of that is the substandard user interface. However, there are no corresponding comments for some massive change that occurred in April 2016, and I know because I read thousands of comments from that period trying to find one to quote here. SSC has always had a fairly loose moderation policy (notwithstanding the occasional ‘reign of terror’ when Scott clamped down on bad commentors) and has worked hard to keep adverts unobtrusive. I remember the only major change to SSC UX was the highlighting of comments you hadn’t read yet (which was an excellent change but I think came later than 2016). The best explanation I have found for a massive change in UX which occurred in April 2016 is that April 2016 was the lowest ever posts per month, probably driven by Scott travelling at during this period and so having less time to post (link) Following April 2016, posts per month spike sharply because Scott changes the frequency of Open Threads from biweekly to biweekly (or fortnightly to twice-weekly if you are going to insist on spoiling my joke). You can see an immediate impact on the proportion of each month’s posts which are Open Threads in the graph below. Note that the actual proportion of Open Threads in the ACX era is probably more like the later SSC era, it is just that my scraping algorithm didn’t catch the paid Subscriber-only Open Threads. So, on this theory, the Commentariat have an approximately fixed amount of time they want to devote to interacting with the comments section each week. The more posts there are, the more thinly they spread themselves across those posts – even if the posts are not core Scott-generated blogposts but rather Open Threads. Perhaps this also explains the changing complexity of language too – quantity and quality of engagement are somewhat substitutes for each other, so in a world where there are more posts than time available to engage with them, the response is to cut back a little on both quantity and quality of engagement. This process could be self-reinforcing; if the community norms become for lower-quality engagement, then this could lead to people trading off quality for quantity even further. This leads to quite an interesting corollary, which is if true then to some extent Scott’s posts are irrelevant to the Commentariat’s enjoyment of Scott’s writing. The value of Scott’s writing is to act as a sort of butterfly net to catch the sort of people interested in Scott’s writing, and then once captured those people interact with each other in the comments section basically a fixed amount basically regardless of how often Scott posts. I don’t know how fully I endorse this theory, but it is interesting to think about how long the Commentariat would remain good even if Scott’s writing genuinely did drop in quality. The real world intruded on the Commentariat’s hyperfixations

Perhaps this also explains the changing complexity of language too – quantity and quality of engagement are somewhat substitutes for each other, so in a world where there are more posts than time available to engage with them, the response is to cut back a little on both quantity and quality of engagement. This process could be self-reinforcing; if the community norms become for lower-quality engagement, then this could lead to people trading off quality for quantity even further. This leads to quite an interesting corollary, which is if true then to some extent Scott’s posts are irrelevant to the Commentariat’s enjoyment of Scott’s writing. The value of Scott’s writing is to act as a sort of butterfly net to catch the sort of people interested in Scott’s writing, and then once captured those people interact with each other in the comments section basically a fixed amount basically regardless of how often Scott posts. I don’t know how fully I endorse this theory, but it is interesting to think about how long the Commentariat would remain good even if Scott’s writing genuinely did drop in quality. The real world intruded on the Commentariat’s hyperfixations

Warp Speed for Air Quality: RFK Jr’s “Make America Healthy Again” philosophy is a horseshoe-theory-style union between typical conservative concerns about purity and typical liberal concerns about the environment. There are many ways it could go wrong, but one place it might go very right is in air quality. Recent research has highlighted the role of air quality in both chronic disease (eg particulate matter in the air causing lung problems) and infectious disease (despite the WHO’s attempts at weird language games, respiratory viruses including colds and COVID are airborne). There are some really innovative solutions (advanced air filters, UV-C technology) on the horizon, but we don’t expect this administration to want to throw a lot of money into blue-sky research. Instead, we suggest taking a page from the first Trump administration playbook and offering Operation Warp Speed style advance purchase agreements, which guarantee a market if and only if the technology works. An air quality Warp Speed could go a step further and target a result that is cost-saving to the federal government. For example, you could set the goal of reducing airborne disease in military housing by 50% by the start of 2028. Because the government pays for military healthcare, this would save costs and also create the evidence needed for private industry (workplaces, nursing homes, cruise ships, etc.) to implement air quality interventions for themselves.

People who got the free insurance had less medical debt at the end of the study period. They described themselves on questionnaires as having better health (55% vs. 68% at least “good”, p < 0.0001), and were more likely to say their health had improved over the past few months (71% vs. 83%, p < 0.001). They described having better mental health and less depression (25% vs. 33% depressed, p = 0.001). However, Robin notes that many of these subjective changes happened immediately, ie before they even had a chance to use their new insurance. This means they’re more likely to represent mood affiliation (eg “I have insurance now, so I’m optimistic about my health!”). There was no difference on objective health measures, including blood pressure, cholesterol, and HbA1c (a measure of blood sugar / diabetes control). Why not? The authors do the math on diabetes. If you look at the graph above, you see that about 12.5% of controls vs. 17.5% of experimentals took diabetes medications, p < 0.05. Studies find that diabetes medications decrease HbA1c by about one percentage point (normal HbA1c is about 5%, so this is a lot). If 5% of the insurance group took diabetes medications and decreased their HbA1c by 1 pp each, then the HbA1c of the experimental group would decline by 0.05 pp compared to the control group. Their 95% confidence interval of the difference was (-0.1, +0.1 pp), which includes the predicted value. So when they say “insurance didn’t significantly change HbA1c”, what they mean is “the change in HbA1c is completely consistent with the consensus effect of antidiabetic medications”. Could the same be true of the other results, like hypertension? We find that the experimental group was 1.8 percentage points more likely to get a hypertension diagnosis, 0.7 percentage points more likely to get hypertension medications, and had 0.8 points lower blood pressure - but that all of these numbers were nonsignificant. If we take the nonsignificant numbers seriously, 0.7 pp taking antihypertensives caused an 0.8 point blood pressure drop in the full sample, meaning that antihypertensives caused a 100 point blood pressure drop in each user. This definitely isn’t true - a 100 point blood pressure drop kills you - but it means that a plausible pro-medicine result like antihypertensives lowering blood pressure 10 point is well within the study’s confidence interval. Maybe the anti-medicine position is that, for some reason, good insurance doesn’t lead to hypertension diagnosis or antihypertensive medication use? If I understand these numbers right, about 22% of Americans have blood pressure > 140/90, the level at which doctors recommend medication. I expect the marginally-insured poor people in this experiment to be less healthy than average, so let’s say 25 - 30%. In the experiment, about 13.9% of the control group and 14.6% of the experimental group got antihypertension medication. Why so low? This study found that only about 60% of participants in the Oregon study who got the insurance even went to the doctor for non-emergency reasons! Subtract out the ones who refused to take antihypertensives, or who have too many side effects, or whose doctors let this fall through the cracks, and I think the 13 - 15% numbers make sense. This study found that insurance increased hypertension medication use by a central estimate of 0.7 pp, not significant, confidence interval -4.5 to 5.8. Let’s take a convenient central estimate of our likely hypertension rate and say that 28% of our population should have gotten hypertension meds. That means the central estimate increased the percent of people who got recommended hypertension meds from 50% to 53%, and the 95% confidence interval includes up to 71%. So my assessment of the blood pressure results from this study is: At the beginning of the study, about 50% of people who should have been on hypertension meds were. The study had too low power to really figure out how this changed, but the central estimate is +3%, and the 95% CI rules out improvements beyond +21%
In the hypertension outcomes of the Oregon study, we lose statistical significance at step 2. The better insurance led to significantly more doctors’ visits. But this didn’t result in significantly more hypertension diagnoses (it only resulted in non-significantly more).
In the diabetes outcome of the Oregon study, we lose statistical significance at step 4. Diabetics with better health insurance were significantly more likely to see the doctor, significantly more likely to get diagnosed, and significantly more likely to get placed on medication, but only had nonsignificantly better health. Why? Probably because, as mentioned before, if diabetes medication worked as well as studies say it does, the study wouldn’t have enough power to detect its effects.

The real world intruded on the Commentariat’s hyperfixations In The Rise and Fall of Online Culture Wars, Scott notes that online feminism was absolutely everywhere from around 2014-16 and then just sort of… disappeared one day. This has some parallels (down to the timing) for engagement with the SSC Comments section – from 2014-16 engagement with the comments section seems to be on an unstoppable upward trajectory and then in April 2016 it just sort of… reverses. I have already mentioned that April 2016 marked an extreme high-water mark for usage of the term ‘SJW’. From what I can see, there’s no particular reason for this specific to SSC – April 2016 has two threads with significant usage of the token, but they are completely random threads – OT47 and Links 4/16 (Links 4/16 does have a link about social justice warriors so that makes some sense, but OT47 doesn’t, so my conclusion is that there is just something that was in the water around that time). This theory says that the Commentariat really liked talking about SJWs, and when they were prevented from talking about SJWs they just stopped engaging with the blog altogether. The problem with this theory is that there is nobody really preventing the Commentariat from talking about SJWs to their heart’s content after April 2016. In February 2016, Scott requested that all Culture Wars topics be quarantined to a single Culture Wars thread on the r/slatestarcodex subreddit (link). This seems like the most common-sense explanation for the observation that the comment section changes dramatically around this time - of course engagement and usage of the term ‘SJW’ falls off when usage of the term ‘SJW’ is quarantined to a single thread in an offsite forum. However, the major problem with this explanation is that it doesn’t fit the data – comment section engagement increases throughout February – April 2016 and only starts dropping in May, when as far as I can see there is no specific events occurring in the r/slatestarcodex subreddit to explain it. Also, in February 2019 the Culture Wars Thread was euthanised (link) but there is no corresponding uptick in comment section engagement as people migrated back from the Culture Wars thread to the SSC comments section. I thought perhaps discussion of SJWs might have been drowned out by discussions of something else, such that it became passé to be discussing SJWs when there was some other Culture Wars issue at stake. This would mirror what happened to online feminism, where it became passé to discuss women specifically and more trendy to discuss intersectionality / race issues from about 2016 onwards. The obvious candidate for this switch is Trump and the rise of the MAGA movement. March 2016 was probably the last period where you could kind of convince yourself Trump wasn’t going to win the Republican Primary. In March 2016 it was just about possible Cruz could have won, but by April 2016 Trump was winning every Primary with decisive majorities. If you are slightly younger you may not have been online during that period, but I can attest that it was completely crazy commenting in political spaces around that time; I’d argue a strong candidate for the most toxic comments section ever is You Are Still Crying Wolf, where Scott offers some extremely guarded non-criticism of Trump, arguing that he was not unusually racist by American Presidential standards. This didn’t make my database because Scott nuked the comments for being too toxic, so we will never know mathematically how bad the comments were, but anecdotally they were pretty standout – closer to 4Chan than ACX in places. The evidence for this hypothesis is kind of mixed – if you abandon all sense of statistical appropriateness you can freehand draw a line which kind of looks like the decline in ‘SJW’ tokens is mirrored by a rise in ‘Trump’ tokens when you normalise the two terms, but you can also do that with any other word that was trending in April 2016, like ‘Snowden’ or ‘Wikileaks’ (or ‘Harambe’ as per the graph below). Looking just at the data it isn’t really a very impressive correlation to draw. I appreciate it is so boring to conclude that Trump is the Great Satan for the millionth time. However, I do think if you add in contextual factors there is reason to be cautiously supportive of a ‘Donald Trump killed the AXC Comments Section’ theory: The volume of ‘Trump’ comments is absolutely massive - around 11% of all comments were about Trump in January 2017, which is greater than comments about Russia during their invasion of Ukraine (10%) and comments about COVID during the first few months of the pandemic (7%). Even a topic like SJWs, which the Commentariat really liked talking about, could only manage a peak of around 1.2% (although eg ‘gender’ peaks at 5.5% and ‘feminis*’ peaks at 3.7%). Concepts like ‘Harambe’ and ‘Wikileaks’ barely register on this scale, at 0.3% and 0.5% peaks respectively. So even though the shape of the two curves looks similar when you normalise them, it is reasonable to believe Trump could have had a significant enough impact on the comments section to dislodge forum norms, in a way Harambe did not.

This tactic reached a new level during the 2021 Ottawa protests, where the Canadian government told banks to freeze the accounts of suspected protesters. All of a sudden their families couldn’t afford food and they had to back down. This is a very effective anti-protester tactic, and there’s no reason that governments who don’t like people protesting them (eg all governments) shouldn’t try it in the future.

The Hindu milk miracle of 1995. Starting from the bottom: In 1995, a man in New Delhi noticed that an idol of the elephant-god Ganesh seemed to be really drinking the glass of milk left as an offering. The story went viral - or as viral as things could go in 1995 - and Hindus around the world noticed the same thing. There was “an increase in overall milk sales in New Delhi by over 30%”. Scientists investigated and determined that a sculpted stone elephant trunk could sometimes absorb milk through capillary action. This was a story about rumor, interpretation, and context, but not really “hallucination”. The drinking effect was real. The Halifax Slasher was a typical supercriminal story. Two women reported being attacked by a mysterious and oddly-dressed knifeman; others followed. “Vigilante groups were set up on the streets, and several people, mistakenly assumed to have been the attacker, were beaten up; business in the town was all but shut down”. Although there was a Halifax resident with a history of knife crime, “he was quickly ruled out of the 1938 attacks on account of his large nose, which none of the 1938 victims had described”. Eventually several of the victims admitted to having made it up, and the whole thing went away. Supercriminal cases most often result from people making things up. Occasionally, seemingly-honest people report seeing the supercriminal in poor lighting conditions across a dark alley or something. But even if we consider these to be “hallucinations”, it is usually the one or two most vulnerable people in a town at the time. I can’t find any examples of true “mass hallucinations” - entire towns seeing a nonexistent supercriminal or monster at the same time. Koro is the psychosomatic disease par excellence; I’ve written about it before here. Victims, always male, believe that their penis has disappeared or retracted into their body; they often blame penis-stealing witches. Koro occurs at some very low background rate in every society (including ours), but occasionally wells up into mass panics in primitive cultures that take witchcraft seriously and have traditions of worrying about this sort of thing. Still, I don’t think any panic ever affects more than half of a village’s males, and usually not at the exact same time; it’s a smoldering panic over days or weeks, not a single instant of horrified realization. Also, although I’m not sure and would love to learn more about this, I don’t think the koro victim is having a visual hallucination of not having a penis at all. I think they think their penis is much smaller or shorter than it should be - which only requires some sort of obsessive worrying and (perhaps motivated) mis-remembering of its normal length. None of these are “mass hallucinations” in the sense where the sorts of visual hallucinations typical of certain mentally ill people occur en masse in a crowd of thousands with >50% prevalence - that is, the type of mass hallucination that would be required to explain Fatima. As far as I know, there are no confirmed cases of this ever happening. Still, from the Hindu milk miracle, we can learn that religious people can miss a real phenomenon for a long time, then notice it all at once with great fanfare. And from the koro cases, we can learn that a rare phenomenon can become more common in situations of widespread belief and social pressure. Interlude: It Seems Like Years Since It’s Been Clear This is around the stopping point of the previous Substack discussion. I’ve tried to cover most of Ethan and Evan’s arguments, go through the chain of rebuttals and counter-rebuttals, and maybe pull on a few of the more tempting loose threads that they’ve left. As best I can tell, this level of investigation ends in a decisive victory for the believers. They have a stock of seemingly-unimpeachable testimonies; the skeptics have only a few leads that don’t seem on track to pan out. Eye damage can maybe produce a few odd effects, but - in the entire history of tens of billions of people living daily underneath a sun that they are able to view at any moment - we have not yet found anyone who reports the full constellation of Fatima experiences just from seeing the sun. No exotic weather phenomenon is a perfect match. Mass hallucinations are real but comparatively weak. At least this is my assessment. Skeptic blogs don’t agree. They propose one of these things (with no consensus as to which one) then act like they’ve debunked the miracle, then skip to the really important part: laughing at how obviously wrong it is. I’ve written before about my disappointment in the skeptical community and why it worries me, and here I feel it as acutely as ever. Sitting with my disappointment and trying to put it into words, I think my worries come down to a tangling of the Bayesian graph. The straightforward Bayesian way to do this is to start with some prior probability that there is a God who causes miracles (let’s say 1%), notice that the evidence for Fatima being a miracle naively seems very high (let’s say 90%), multiply out, and end up with a higher (8.3%) probability of God’s existence and a lower (8.3%) chance that Fatima in particular was miraculous. This is liberating. It lets you say “This piece of evidence is very strong, but my prior is very low, so even without being able to debunk the evidence, I continue to disbelieve.” But doing this the straightforward Bayesian way doesn’t work. First of all, what would it mean to naively (even before factoring in that you don’t believe in miracles) say Fatima seems 90% likely to be miraculous. Before factoring in that you don’t believe in miracles, surely the probability is much higher! But also, if you try this, then as soon as you find two similar miracles (I’ve been told the next two are the Eucharistic Miracle of Lancio and the Miracle of Pellicer’s Leg) your probability of God goes up to 88%! But I don’t think there’s any real atheist whose probability would rise in such a straightforward linear way. You need some kind of model where either it’s almost trivially possible to generate an arbitrary number of convincing-yet-false miracles, or it isn’t. But this doesn’t match the “virtuous” approach of addressing each miracle on its own terms - where you try to understand the Sun Miracle by learning things about the sun, or entoptic phenomena, or 1910s Portugal. And it does match the skeptical approach I’m complaining about, where you say “it’s probably swamp gas or something, lol, imagine being so dumb that you believe in miracles.” So I cannot object too strongly. Still, my greatest fear in this and all other problems of reasoning method is the trapped prior, where people take this too far and become impervious to evidence entirely. I think it’s worth untangling the whole Bayesian graph, trying to keep this whole structure in mind, if it prevents people from accidentally propagating an update down a logical chain, then propagating the same update back up the chain, again and again, ad infinitum, until they become arbitrarily sure of themselves. “We can be sure all miracle claims, even the convincing ones, are false, because there’s no God - and we can be sure there’s no God because all miracle claims are so risibly false.” Even if this is harmless - even if it turns out correct in the case of religion - it teaches such dangerous habits of mind that I’m willing to err in the direction of going way too far taking such claims seriously - at least in the “entertaining an idea without accepting it” sense. Everyone gets to decide what is and isn’t worth their time. I think deciding that these sorts of miracles aren’t worth your time is fine, as long as you’re propagating all the probabilities correctly and not accidentally treating your own hurriedness as a cause to update the rest of your belief graph. As for me, I don’t know, I just find this fascinating. In Evan’s skeptical take on the conversation, he starts strong, but after the topic switches to Part LXXVII of Dalleur’s discussion of photograph angles, he stops and asks: What the fuck are we doing? What are we talking about? What have I spent (conservatively) 18 hours of my life on? We’re addressing what Stanley Jaki called the most important event of the 20th century! We’re debating the existence of God, the most important question possible! If God is real, then nothing could be more important than establishing this: in the best case, we will come to believe; at worst, we will be able to tell St. Peter that our failure was honest and not from lack of trying. If He is not, then we can do whatever we want here on Earth, and surely one of the noblest ways to spend our short existence is expanding the frontiers of the known into the borderlands of mystery! In particular, if the God of Fatima exists, we are in deep trouble. I said I wouldn’t talk about exactly what the Virgin Mary told the child-seers, but the short version is that the First Secret was a very, very nasty vision of Hell. It looked exactly the way a ten-year-old child might expect: a lake of fire populated by ebon-skinned demons and horrendous tortures; the lead child-seer said that if the Virgin had not begun by promising that she personally would never go there, “she would have died of fright”. As it was, the consequences of the vision were grim. The child-seers got it into their minds that they could perhaps save sinners from the fire by “doing penance”. They drank only stagnant, scum-encrusted water, in the hopes that this might help some otherwise hell-bound soul; on some especially hot days, they ceased drinking water at all. When they found particularly painful ropes, they tied them around their bodies so hard that they bled (later, the Virgin mercifully told them they didn’t need to wear the ropes at night - they could stick to daytime only). After so many mortifications, they were easy prey for the Spanish Flu; two of the three perished before their tenth birthday. As they lay dying in the hospital, they were recorded as freaking out every time they saw a nurse or visitor with “immodest dress”, saying that they would not act in such a way if they knew how long Eternity was, or what awaited them there5. If all of this is the true opinion of the Lord of the Universe, we had better figure it out quick. If it isn’t, then the words of the Grupo Anticlerical: People! Let us always fight! From the victory of progress, science, freedom, and free thought, will result human happiness, joy, love, fraternity, respect for women, veneration for mothers, adoration for children, affection for the elderly, protection for the sick, the unfortunate, the tortured . . . O most holy mothers! O holy, pious mothers who so love your sweet little children! Have compassion on your beautiful little children, sacred fruits of your blessed wombs! …take on new meaning and urgency. I will admit my bias: I hope the visions of Fatima were untrue, and therefore I must also hope the Miracle of the Sun was a fake. But I’ll also admit this: at times when doing this research, I was genuinely scared and confused. If at this point you’re also scared and confused, then I’ve done my job as a writer and successfully presented the key insight of Rationalism: “It ain’t a true crisis of faith unless it could go either way”. But now that we’ve let Ethan, Evan, and the rest dig us into as deep a hole as possible, let’s try to dig our way out. 3: Our Lady Of Everywhere Else One question that Ethan, Evan, and Dalleur fail to ask is: what if people are basically always seeing the sun spin and change colors and and fall from the sky? What if this is the most common experience in the world? What if it’s a minor miracle every time you get more than a handful of people together and they don’t fall down in awe and terror at the manifestations of the sun? Goncado Xavier de Almeida Garrett is one of the star witnesses of the Fatima miracle, quoted above. His testimony comes from a letter written to Father Formigao, a local priest, about two months after the event. But although pro-Fatima sources quote the testimony at the beginning of the letter, they conveniently leave out what follows: I ask your excellency to please tell me if you confirm this narrative: the Bishop of Portalegre and Mrs. Maria de Jesus Raposo report that while they were with other people in Torres Novas, on the 20th of October at the end of the day, they saw the sun rotate and change its colors. They said this was different from Fátima and did not have the importance of October 13th. I would like clarification on the differences. It is urgent to know what the differences are, since they attended both […] Until now, no one saw the sun's sparkling rotations, and now everyone sees them many days and many times. Many days and many times? Remember, the Virgin Mary first appeared at Fatima on May 13. She promised to return on the 13th of each successive month until October, when she would perform a great miracle. But she never said she wouldn’t perform any miracles until October. So on the 13th of each month, a medium-sized crowd gathered. They didn’t leave disappointed. I won’t include every claimed supernatural occurrence, but here are the ones relevant to our subject: Olimpia de Jesus, about July 13: [On July 13], at her sister-in-law's house, when they heard the people shouting, he asked, "What's going on over there?" [Olimpia] looked at the sun and said, "The sun is different." The people came and reported that they had seen signs in the sun and in the sky. Joaquim Inacio Vicente, about August 13: This hour was a moment of terror for all who were there. Some lost their senses, others believed it to be the last day of their lives and their day of Judgment, and for some, afterwards, it was a wonder to see the admirable colors that successively took on the clouds that obscured the sun's rays—colors from bright red to pink and from there to blue—the color of anise, as several people declared to me minutes later in my home. Leonor de Avelar e Silva Constancio, about August 13: Everyone looked up at the sky, which was covered by a light cloud, like a very fine white lace, pink in places. The sun, which had been completely hidden for a moment, left us illuminated by a strange light, with yellow spots visible on the ground and above us all, and a great drop in temperature, as happens during a solar eclipse. Manuel Pedro Marto, about August 13 and September 13: [On August 13, he] saw a kind of luminous globe rotating in the clouds […] On September 13th, he also went to Cova da Iria. He was a little away from the children. He saw nothing, nor heard anything, but he heard that some people had seen extraordinary things in the atmosphere. Joaquim Xavier Tuna, about August 13 and September 13: On the 13th of August, I saw the sun lower in the sky at the hour of its appearance. It never lowered as much as that time, not even on October 13th. All the objects around me turned yellow. On September 13th, I saw a large cross emerge from the sun and head east. Its progress was not very hurried. Sometimes it appeared, sometimes it disappeared, until it disappeared from view. I also saw other things that I cannot explain. In the Lapas area, there were people who, at the same time, saw the cross. Then there was the great miracle on October 13. Remember, I was only able to find a handful of negative testimonies - people who said they didn’t see it. One was from a woman named Leonor das Dores Salema Manoel, who said she saw “nothing of what others saw”, at least at Fatima. But on the drive home from Fatima that evening6: I saw [the sun] pass through different colors that I can't remember and it turned green, very light green, like a green salad with a golden rim around it, and spinning. Very long rays seemed to touch the earth and the sun seemed to be separated from the sky. Then the sky took on pink flashes, changing to a yellowish hue around the sun, and further away, spots here and there. After a few long moments that I can't remember, it returned to normal and I couldn't look at it again. The next occurence was early the following year. From the parish inquiry’s interview with Jacinto de Almedia Lopes: He further said that on the day of Our Lady of Purification, that is, on the second of February, 1918, he about 3 o’clock in the afternoon, being in the same place, he noticed signs in the sun identical to those of the thirteenth of October, which he had not noticed on many other days when he had been there. And next, from a letter by Gilberto Fernandes dos Santos: I must inform you that I went to Fátima on [June 13, 1920]… at that very moment, the people were kneeling on the ground, shouting, praying loudly, weeping, begging forgiveness with their hands raised, because they were witnessing a solar phenomenon similar to that of October 13, 1917. And next, from Dr. Henrique Weiss de Oliviera, describing events on May 13, 1923: I ate my meal in a car on the road near Cova da Iria [in Fatima], from half past noon to one in the afternoon, and when I returned to the Chapel, I heard the groups I passed exclaiming in admiration about a marvelous phenomenon that they claimed was occurring in the sun toward which they were directing their gaze. Deeply doubting the repetition of the marvelous phenomena that had dazzled thousands of people, according to reliable reports, during the last apparition of Our Lady in 1917, I was about to pass on without even bothering to look. I remembered, however, that when I first went to Fátima on October 13th of last year, and upon hearing similar admiring rumors around me, I had seen nothing during my quick inspection, perhaps because I was filled with that spirit of doubt. I therefore wanted to be certain this time so that I could, with full awareness, give my testimony to whoever and whenever I was asked. And, having stopped near a group and stared at the sun, carefully shielding my eyes from the direct sunlight, so as not to see anything, they immediately advised me to insist that I would see something. It took a long insistence to finally see what amazed everyone and caused astonishment that I could not see it. And I saw with precise clarity, and twice, what the common people, in their imaginary language, very accurately likened to: almond blossom petals. They fell from a great height (no longer seeing them detach from the sun as the people around me saw them) For myself, I finally, and after a considerable time, concluded that there is no such natural phenomenon, neither known nor described, thus leaning toward the supernatural. Today I firmly believe that this was the case, because I have had testimonies that allow me to reconstruct the phenomenon as it appears to have occurred according to these testimonies. First, one could gaze at the sun for a long time and with impunity, seeing magnificent phenomena of beauty and color; then began an abundant rain of the aforementioned petals; and when I arrived, it was no longer possible to gaze at the sun, and the phenomenon, which had been quite lengthy, was at its end, which explains my difficulty in witnessing it now. And from Joao Amael, on October 13, 1925: I do not know why, I suddenly felt a desire to look at the sun. [I would hear] other educated persons admit having seen phenomena in the sun on that day and hour. I looked at the sun. Before that, nothing special could be seen. But now I looked at the sun without hurting my eyes, without any retina resisting. I became more intent. To my astonishment, the sight became even clearer. The sun turned on itself in a very small circle, and in the center it turned into a dark disk in rapid rotation. During some minutes, very impressive and overwhelming, I could clearly verify this strange process. Then, without revealing anything of what I observed, for fear of autosuggestion, I asked my companion to look at the sun and see whether it really appeared. And my companion was describing exactly the phenomenon, the same extraordinary phenomenon. The test was achieved. And I gained further assurance, when various other people later told me that they had seen what I saw clearly, at the same hour, as they kept looking at the sun, without the slightest sensation of pain. Amael’s report of a miracle in 1925 is the last recorded case I can find at Fatima. I don’t know if this was when the sun miracles stopped happening there, or when people stopped including them in the Critical Documents collection. In either case, there were plenty of other places willing to pick up the torch. 3.1: The Ghiaie Variations As far as I can tell, Fatima was only the second-largest crowd to have ever witnessed the Miracle of the Sun. The largest was a group of 200,000 - 300,000 people in Ghiaie, a tiny village near Bonate, Italy. On May 13th, 1944 - the same day of the year that the child-seers of Fatima saw their first apparition - a seven-year old girl went out to pick flowers and had a vision of the Virgin Mary. The Virgin promised to return to her for nine successive evenings; at some point (although I cannot follow this part of the story) she must also have promised to return four times the following week, as large crowds gathered in expectation. According to my source, on the ninth appearance: Many testimonies from the site of the apparition and from surrounding villages described an impressive solar phenomenon. The sun came out of the clouds, whirled dizzily on itself, and projected beams of yellow, green, red, blue, and violet light in all directions. The beams of light colored the clouds, fields, trees, and the stream of people. After a few minutes the sun stopped its whirling, and those phenomena began soon again. Many noticed that the disc had turned white like a Host. The clouds seemed to be lowering down on the people. Some noticed a Rosary in the sky. Others saw a majestic Our Lady with a trailing cloak. Some people, who were at greater distance, saw Our Lady's face looming in the sun. From nearby Bergamo many witnesses observed the sun become pale and radiate all of the rainbow's colors in all directions. They also noticed a large yellow light beam falling over Ghiaie, perpendicularly. The blog says there were similar solar phenomena during the tenth and twelfth appearances, as well as on the following June 13th and July 13th7. All of this is from a random Catholic blog; can we find clear testimonies? The miracle of Fatima was heavily promoted by Portuguese, Vatican, and American Catholics, leading to a large body of sources being available in English. The Ghiaie apparition has gotten less attention, and so I can find fewer testimonies, have had to clunkily machine translate some things, and had a harder time tracing the exact chain-of-transmission. Still, here’s what we’ve got, mostly from here: Don Giuseppe Piccardi: The people cried out to the miracle; I turned between the intrigued and the distrustful, and I saw the sun that-comes from the clouds - turned on itself and the speed of movement seemed to be skidding. At the same time I saw that he projected light beams, then, for me, almost constantly yellow gold. This color I contemplated it even when the sun was veiled with uncaught clouds. Slightly hard to figure out from the machine translation, but I think this is Bishop Adriano Bernareggi: At 6:00 PM I was at the Patronato for the feast of St. John Bosco. Just at that time I finished speaking in front of the church. Then I entered the church for the Benediction with the Blessed Sacrament. But most of the crowd remained outside because they said they had observed for about ten minutes the sun rotating on its axis, also suddenly changing color: yellow, red, blue. The sun could be observed without disturbance. The phenomenon was also observed in other places. I only noticed at the end of the service a yellow color in the houses, as when there is a partial eclipse of the sun at sunset. At 7:45 PM they said the phenomenon was repeated. I watched too. By staring into the dazzling sun, you could end up seeing the sun stand out clearly, giving the impression that it was rotating. Then everything took on a red color. But then it was clearly an optical phenomenon. Don Luigi Cortesi, a local seminary teacher who was a strong skeptic of the apparitions and even borderline-kidnapped the child-seer to convince her to recant: A shiver runs through me for a second. I react forcefully, forcing myself not to lose my mind, not to let myself be overwhelmed. I desperately squeeze my pupils and look at the sun: I see a large, clear spot without sharp edges, then, when my eye has adjusted, I see a disk of intense whiteness that seems liquid. Staring at the edges of the disk, I detect a dizzying rotation, like an electric circular motion, like a dizzying pinwheel, except that the direction of motion changes rapidly from left to right and then from right to left. I remember Fatima. Except this time, the sun revolves around a fixed axis, without moving in the sky. I return to the earth, to the crowd: I notice that the faces, the hands, the trees pierce through all the colors of the rainbow. It's natural, I think to myself: when the eye is offended by an intense light or an equivalent stimulus, it projects a stain on objects, which fades from red to violet and tints the objects it encounters with different colors; the stain disappears when the eye, rested, has returned to normal. In fact, a few minutes later, I no longer see those iridescent colors; every object has returned to its natural hue. The phenomenon of rotation leaves me dubious. A neighbor offers me his smoked glasses, and I look: the sun continues to rotate. He offers me a telescope, and I invert it, the screen, and look: the sun is still rotating. Then I can't take it anymore: even today, I'm not convinced that seeing a cosmic prodigy is worth losing my sight. Back then, I wasn't even convinced I was seeing a prodigy, since a plausible natural explanation for the phenomenon quickly emerged in my mind. However, urged by the neighbors to get excited, I remain silent. And I silence them by pinching and slapping the arms of those around me, which are stretched out towards the sky." From the parish bulletin of Tavernola, the exact author is slightly confusing but it was either written by or signed/confirmed by Piero Bonicelli, local provost: On the 28th in the evening of Pentecost, something happened that made a profound impression on everyone. At 6:00 PM sharp, a dimming of the sunlight was felt, accompanied by a sudden flash of lightning, first clearly observed by some bowling players. Looking at the sun, one saw first green, then bright red, then golden yellow, and then it spun around dizzily. At that spectacle, people poured into the streets... One can imagine their comments. The women recited the Holy Rosary, punctuated by the words: "Oh, how beautiful!" After ten minutes, the sun returned to normal. Comments? None. We await an explanation from the appropriate source. For now, we're content to hear the usual strong-minded people call us poor, deluded people, but don't you think this is a rather general illusion? In any case, for now, we're deluded: we'll see later. The parish priest of Tavernola, director of the bulletin, sending this issue requested by Father Piccardi, wrote on June 27, 1946: I must assure you that, as written, it is true, and I can also tell you that I was among those deluded that evening. To be prudent, I didn't go out into the street where people were shouting about a miracle, but from a slightly hidden window, I watched the sun change color and spin rapidly... illusion? Many of us here in Tavernola have been deluded. I can also tell you that I was pleased that such an illusion existed in Tavernola, since the people here have always had a great devotion to the Madonna. There may be more testimonies at this site, but they’re in very old scanned documents that it would be too time-consuming to stick into my machine translation pipeline. Another source says that “On February 24, 1994, [the TV show] ‘Detto tra noi' (Raidue), interviewed some witnesses, who confirmed the solar phenomena of May 21 1944 that were watched by many people“. I think a few hours extra work by an Italian speaker could produce at least five or ten extra Ghiaie testimonies, maybe many more. But as it is, we have enough to try something interesting: let’s recreate Dalleur’s analysis, but for Ghiaie. At 6 PM, the sun was shining from almost due west. For the sunlike light source producing the miracles to mimic the real sun, it would have also had to have been to the west of Ghiaie. If we assume it was the same distance as Dalleur’s Fatima light source, it would have been about 2-3 miles to the west of Ghiaie, which puts it above the village of Merate. We know from the last testimonial that the phenomenon was seen clearly in the village of Tavernola Bergamasca, which is about 22 miles from Ghiaie and 25 from Merate. An Italian source also reports sightings in Brescia and Piacenza, each about 35 miles from Ghiaie. So a Dalleur style analysis might conclude that this event also had a 25 - 35 mile visibility radius, similar to Fatima’s. …unfortunately a 25 mile circle centered on Merate includes the city of Milan, population 1.1 million, which produced no reports of unusual solar activity. And Milan had clear line-of-sight to Ghiaie and Merate, and so probably better viewing conditions than Tavernola, which (you can see from the map above) has some intervening hills. Might the miraculous light source have been like a spotlight, aimed in only one direction - that is, east to Ghiaie and Tavernola, but not southwest to Milan? This would contradict Dalleur’s Fatima analysis, since one of the most dramatic testimonies comes from the city of Minde, which is on the opposite side of the presumed light source from Fatima. I don’t really think it’s possible to maintain a theory where this phenomenon gets transmitted through normal geography. 3.2: Mary Such Cases At this point, the reader will get the general idea, and we can start moving faster, as there is a large amount of ground to cover. Heroldsbach, Germany, 1949: The Virgin appeared to four young girls. Rumors spread, crowds gathered, and on December 8th, 10,000 people saw another sun miracle. Here are about a hundred testimonies, gathered with typical German thoroughness. An expert meteorologist brought in to investigate summarized them as follows: If one now considers the testimony in detail, one encounters a surprisingly small agreement of the observations made. One witness has seen a red sun, the other a yellow, an orange or pink with blue and green, or a whitish sun. A silver one was also observed or all the colors mentioned in colorful change. One wants to have observed an oversized, the other a first small or normal, but then rapidly enlarging and rushing towards the viewer in a frightening way. Most of the witnesses noticed that the solar disk rotated very quickly in two or three phases of rotation for about a quarter of an hour. The Catholic Church condemned the apparition and miracle as fake, even going so far as to excommunicate the child-seers. Later they relented slightly and un-excommunicated them, but their official position is still that nothing supernatural happened - this sun miracle was merely an overly enthusiastic hallucination! Necedah, Wisconsin, USA, 1949: A housewife named Mary Ann Van Hoof claimed to have seen the Virgin Mary. This is among the less plausible visitations: Van Hoof, who was raised Spiritualist, also claimed to have seen Joan of Arc, George Washington, and Abraham Lincoln. The messages she channeled seemed less like tidings of peace and love than like a particularly unhinged Truth Social post, and included warnings about the Rothschilds. Still, rumors spread, crowds gathered, and on August 15 1950, 50,000 - 100,000 people showed up hoping for a miracle. As for what happened next, Wikipedia says that “witness accounts vary significantly”. WaPo says that “observers saw nothing unusual” and LIFE mentions nothing out of the ordinary. But other sources report sun miracles, and I was eventually able to track down three testimonials in a summary of articles from a local newspaper, which states that “after a rainy morning…”: It was about noon when Van Hoof came out of the house and a woman screamed, “By God, it’s really true,” and fell to her knees. Then it happened that the Rapids woman and so many in the crowd saw the sun, covered with a dark, greenish gray disk, spinning down toward the earth. And she testified, “I thought the end of the earth was coming and fell to my knees.” A Pittsville woman also described the sun spinning closer to the earth. “I and many other people, fell to our knees in awe.” The Daily Tribune visited the Oct. 7, 1950, event — a 25-minute “last” message from the Mediatrix to the “throng” of 50,000. Responding to this seventh vision, gasps were heard from women who again saw the sun behaving oddly. A Catholic priest told reporters he saw the sun whirl clockwise and jump. The Catholic Church condemned the apparition as fake, and declared van Hoof’s followers “a cult”. Lubbock, Texas, USA, 1988. Really? Really? Nothing could be more natural than for the Queen of Heaven to appear to kind-hearted shepherd children in Portugal. Even an appearance in war-torn West Germany makes a certain amount of sense. But Lubbock, Texas? I suppose this must have been how the cool Sanhedrin members felt when they learned the Christ hailed from Nazareth. But that doesn’t make it any better. Anyway, rumors spread, crowds gathered, and on August 15, 1988, about 10,000 people witnessed the Miracle of the Sun. Here is an indirect testimonial, a man describing his wife’s experience: A large crowd had gathered outside Saint John Neumann Church on that very hot August afternoon on the Feast of the Assumption. Mass was being said in the afternoon, and around the time of the Consecration, suddenly her cousin’s wife (a convert, if you remember) said “look at the sun”. When she did, the sun was pulsating, it would look like it was coming down to earth and then go back again, it spun around in circles, much the same as what took place in Fatima in 1917...and changed colors. She looked at it directly for 15 minutes or so without any damage to her eyes. As my wife looked around, the people in the crowd seemed to be bathed in various colors. During all this my wife even saw The Blessed Mother. The Blessed Mother was extending her arms in what appeared to be a welcoming gesture. But not everyone had the same experience that day: her cousin’s wife and our son saw and believed instantly, but her cousin and brother saw nothing at all. Why did some see these events and others did not? We don’t know...not enough faith? Or perhaps they had enough faith, and they didn’t need a sign! Here we have something special: according to the Los Angeles Times, one pilgrim took a poll about who saw what: A push was on to assemble evidence for the commission in a lawyerly way. Testimonies from 247 people present at the feast had been recorded. The statements were transcribed by volunteers and stored in a computer. Joe James himself indexed the information: 186 had witnessed the spinning of the sun; 75 had seen the Virgin; 64 Jesus; 18 an angel. How could anyone ignore the bulk of such documentation? We don’t know how the 247 people were selected, but very naively it seems like 2/3 of those present saw the sun spinning. This also matches the first person listing 2/4 family members. (the Catholic Church withheld judgment, refusing to either endorse or condemn the visions) Benin City, Nigeria, 2017. On October 13 2017, crowds gathered around the world to celebrate the 100th anniversary of the Fatima miracle. One such commemoration happened in Benin City, Nigeria, where 30,000 people attended the National Marian Congress and witnessed the re-dedication of Nigeria to Mary’s Sacred Heart. As the speakers commemorated the Fatima event . . . . . . someone pointed to the sky and shouted “It’s happening again!”. It was, indeed, happening again. You can read about ten testimonies here. I’ll quote just one, from Brother Joseph Obiemeka Azih: Immediately after the 3:00 p.m. Divine Mercy prayers, there were brief showers of rain. Then came sudden brightness of the sun, which was hitherto hidden behind layers of dark cloud. We also observed rather surprisingly the mysterious shooting of the sun forward and backward. Intermittently emitting of powerful bluish and golden colors of light from “Our Lady clothed with the Sun.” The sight was indescribably beautiful. We were busy staring at the bright sun steadily for more than twenty minutes without blinking an eye even for a second! People around us were dazzling and reflecting these bluish and golden colors on their dresses and faces. What a mystery! More than 30,000 people inside the arena were seen peering at “the dancing of the sun” bewildered. The miracle lasted for more than 45 minutes after which there was [a] heavy downpour which the Bishops present said [were] “showers of blessing.” I was able to confirm that some of the people whose testimonies were listed on the site are real Nigerian Catholics whose existence is attested in other sources. Two weeks later, there was another Nigerian commemoration of the Fatima anniversary, in Lagos, and a sun miracle happened at that one too. 3.3: Made You Gaze At Medjugorje Medjugorje (Bosnia, 1981) is in many ways a typical Marian apparition site, much like the ones on the list above. Child-seers, warnings to repent, sun miracles, you know the story by now. But in Medjugorje, the miracles keep happening. Pilgrims - or, more cynically, tourists - go there just to see the sun miracles, and many come back satisfied. You can find blogs by people who went to Medjugorje hoping to see a sun miracle, and on their first or fifth or eighth or whatever day, there’s a crowd of people, yelling and pointing at the sun, and they look up and see it too. Here’s an account from Catholic blogger Father Dwight Longernecker: I was an Anglican priest living in England, in 1985 when I was invited by a group of Anglicans and Catholics to visit Medjugorje. I didn’t want to go. Being a former Evangelical-fundamentalist I wasn’t too keen on apparitions of the Blessed Virgin. I opted out. They insisted. I dug in my heels. They said someone else would pay for it. I didn’t want to go. They cajoled and twisted my arm until I said ‘yes’ [...] On our second day there I sat on the balcony of our guesthouse with a large woman named Eleanor. As we began the rosary I looked up and the sun was a blaze of light in the sky. I looked down to the car parked below and the sun was reflected in the hood of the car as a blaze of light. Eleanor and I prayed the rosary together. I had my eyes closed. At 6:20 Eleanor gave me an elbow in the ribs and pointed. The sun was now a disc of white light in the sky like a Eucharistic host. Then as I watched it began to spin, first clockwise then anti clockwise. Sparks spit out from the rim of the sun like a firework. I looked down and the sun was a white spinning disc on the hood of the car. I don’t think this would have happened if it was just my eyes playing tricks on me. Plus, Eleanor saw it too. That’s why she gave me an elbow in the ribs. I am not sure how long this lasted, but when we spoke about it to our fellow pilgrims they said many people in the town square had reported the same phenomenon. Some of these tourists capture the phenomenon on video. Unfortunately, the videos are of three types: Videos of a bunch of people pointing at the sun, and shouting the word “Miracle!” in various languages, and obviously looking extremely excited, but the sun itself looks totally normal, and the person taking the video apologizes and says that their camera isn’t good enough to capture it.

11: Update on Ozempocalypse: some pharmacies have stopped selling compounded GLP-1 drugs, others continue, with various flimsy legal excuses. Cremieux has a guide (partly subscriber-only) on how to order and use cheap “research chemical” GLP-1 from from peptide companies. And the Trump administration cancelled a Biden initiative to make GLP-1 drugs available via insurance.
