Your Book Review: The Accidental Superpower

May 21, 2021 · Original source

Then there’s something like the CNBC effect. Why did stock prices increase/decrease on any random day? Intelligent people don’t think like this, but there is demand for “analysis” of such questions. Some people go so far as to say that it’s the same reason that Wall Street provides market research; the demand is there, so someone will sell it. It reminds me of a story I heard from Reason columnist Ron Bailey. When he was selling The End of Doom, an agent asked him to change his thesis, because optimism doesn’t sell, whereas doom could make him a very rich author. I very much doubt that Zeihan created his analysis in order to arrive at the conclusion that we’re going to see a global Disorder over the next decade, 11 but once you see structural incentives it’s hard to banish them from your thoughts (see also, Meditations on Moloch).

ACX Grants Results

Will Jarvis and Lars Doucet, $55,000, to create an automated land value assessment model for two Pennsylvania counties. You all know Lars as the guy who keeps writing guest posts here about Georgism. Now he wants to take it to the next level and start building tools for the Georgist future. This program would act as proof of concept that counties can assess land value relatively easily and accurately. I was on the fence about funding it because they can create a beautiful program with 100% success and then counties can just continue to not be Georgist for the same reasons as usual. I'm going ahead with it because I trust Lars who believes this is the best way forward, and because it seems like the sort of thing that could eventually grow into a Georgist think tank at some point in the future. They’re interested in talking to anyone who has experience in mass appraisal, Georgist or not, as well as applied data scientists and machine learning researchers.

Birth Order Effects: Nature vs. Nurture

June 01, 2022 · Original source

Source here; thanks to Emile for the graph That is, of people with exactly one sibling who read this blog, about 72% of those are the older of the two children in their family, compared to only 29% who are the younger of the two (where by chance we would expect 50-50). This was surprising, because at the time lots of studies had shown there weren’t really birth order effects (that is, firstborn siblings had no major personality differences compared to laterborns). I theorized that maybe for some reason it was easier to find by looking in a heavily-selected group of people and asking members about their birth order, compared to getting a random sample and trying to correlate birth order with things. Sure enough, later amateur research revealed strong birth order effects in physics Nobelists and great mathematicians (and potentially Harvard philosophy students). Given that readers of this blog are highly-educated (about 37% have masters or PhDs) and mostly in STEM (41% programmers of some sort), plausibly birth order affects something about intelligence, education, or STEM orientation (somebody should check literature and peace Nobelists!) Followup research by Less Wrong user “Bucky” determined that the effect fell off with age gaps; the closer in age you are to your sibling, the stronger an effect birth order has: I continue to be confused by this extremely strong effect which most of what we know about psychology says shouldn’t exist. So in 2020, I asked my readership some even more complicated questions about their family situations, in the hopes of teasing out why this is happening. I’ll be honest - I think I over-reached here. I’m not very good at statistics, and this is a weird statistical problem: the dependent variable is whether the case ended up in the sample at all! I wasn’t able to figure out a good way to use most of the data you gave me. And the stuff I did use, I mostly made work by slicing and dicing so much that the sample size got pretty low, even when I started from 8,000 survey respondents. I’m publishing this in the hopes that it will inspire someone else will more domain knowledge to do a sophisticated re-analysis. But for now, here’s what I’ve got. Confirming Old Results With The 2020 Dataset The 2020 dataset also shows a strong birth order effect in people who read this blog. In 2018, among people with exactly one sibling, respondents were 2.51x more likely to be the older sibling than the younger (72%). In 2020, the number was 2.39x (71%). Change with age gap is shown below: Note truncated y-axis This seems to be broadly similar to the 2018 results. There was an anomaly in 2018 where some categories seemed to drop off surprisingly quickly between 7 and 8 years, which I thought might be meaningful. But Bucky’s analysis showed this was probably a coincidence, and indeed it doesn’t show up in the new data. Does Sex Matter For Birth Order Effects? I wondered if there might be a smaller birth order effect for people with opposite-sex siblings. One possible explanation for the birth order effect is children trying to get out of the “shadow” of their older sibling and differentiate themselves in some way. But children are already pretty different from an opposite-sex sibling and might feel less pressure in that situation. But this doesn’t seem to be true. The percent firstborns in sibships of two on the survey was 70% among people with a same-sex sibling, and 71% among people with an opposite-sex sibling; no real difference. Do Biological Or Social Factors Produce Birth Order Effects? All previous results are for biological siblings. But it might be worth asking the question separately for biological vs. social siblings. One could imagine either biological or social causes of the birth order effect. For example, some biologists speculate that pregnancy depletes choline, that it takes a long time for choline stores to recover, and that a second child born within that window will have less choline available to build their nervous system, which could be bad. But also: maybe if you have an older sibling, your parents can’t pay as much attention to you when you’re a kid, and you learn less. This was very hard to test for. Again, I wasn’t able to use traditional statistical tests because I’m trying to determine whether someone was in the sample at all, rather than whether two variables are related. It was easy to check normal birth order because I could compare people with exactly one older sibling to people with exactly one younger. It was harder to do with things like adoption in the mix, because that could introduce a bias: are parents more likely to adopt out their first child (because that’s when they’re most unprepared for parenting)? Are adoptive parents more likely to adopt when they already have children of their own (because they’re comfortable with child-rearing) or less likely (because they really want kids and can’t have them biologically)? I had no way of getting controls for these questions and so I couldn’t do a lot of the analyses I wanted. But I did two relatively weak analyses instead: First, I took the entire set of people in weird situations - people who said their number of social siblings was not the same as their number of biological siblings. In this group of 174 people, biological firstborns made up only 61% of respondents with one sibling, notably less than the 71% in the entire sample. That suggests that the unusual social situations are having an effect. You shouldn’t update on the fact that it’s still higher than 50%, because some of the people’s weird social situations don’t affect their status as social firstborns. Second, I tried to compare people who were firstborn under a biological definition but not a social definition, to people in the opposite situation. There were 40 people in the sample who were biological but not social firstborns, and 60 people who were social but not biological firstborns. Again, this suggests that social firstborn-ness is more important as an explanation than biological firstbornness, although it doesn’t rule out the latter having some effect. I additionally tried to compare two different types of social firstbornness - one where no older siblings lived in the house when you were growing up, and one where your parents had never parented another child. There weren’t many people discordant on these two measures (29 vs. 20 respectively), but for what it’s worth, the ratio was in favor of the first type. Since I wasn’t very confident in my analytical abilities here, I asked Bucky, who knows more and who did good work analyzing the last dataset, to look into this (we worked independently and didn’t tell each other our results until we were done). He writes: It seems to me that the effect is entirely caused by social siblings. I filtered for only people with 1+ biological but 0 social siblings. There were 24 oldest biological children in this group vs 21 2nd children (or 25 youngest children with a large overlap between 2nd oldest and youngest groups). This significantly differed from the ~0.7 fraction of older children in the general surveys (p<0.05 or p<0.01 depending on whether I use the 2nd oldest or youngest as the comparison) and is close to a 1:1 ratio. I then filtered for only people with 0 biological but 1+ social siblings. There were 51 oldest social children and 23 2nd children (or 26 youngest children again with large overlap). This differs significantly from a 1:1 ratio (p<0.001 or p<0.01) and matches pretty well with the 70% of the Birth order effect. I tried doing some filtering by age gap (2-7 years) and the results were compatible with the same result, although the sample sizes got too small to really conclude anything. For dealing with answers left blank I treated them as 0 unless it looked like the whole section had been missed out. If I ignored any respondents who left something blank I got similar results (smaller sample size but ratios are even further in favour of the social hypothesis). I checked for categorisation errors by looking at respondents’ descriptions of their families and they mainly matched pretty well with the numbers given so I think the data should be considered reliable. I did chuck a couple of results out which seemed unreliable and there was one row which was a repeat so your numbers might not match up exactly (plus you have the non-public data). There are a couple of confounders in the analysis such as whether e.g. oldest children are more likely to be adopted or how much you know about your birth family depending on how old one was when the family unit changed etc. I don’t see a realistic way to account for these but I also can’t see any of them being big enough to explain the difference in the results. Hopefully this matches up with what you found! I think this suggests birth order effects are social rather than biological. So What Causes Birth Order Effects? Based on this analysis, it seems unlikely they are biological. Based on my very weak sub-analysis, and on their tendency to decay with larger age gaps, it seems they have more to do with the social presence of a sibling in the house than with any changes in parenting style (ie your parents learn to parent differently). Two explanations that satisfy both those criteria: Parents are able to devote their full attention to parenting their first child, but only half of their attention to parenting their second. Firstborns get more quality time with their parents during the first few years of childhood.

The average SSC reader is white and 33 years old, so we should expect a twinning rate of 2.4%. But in fact it should be a bit higher than this, because the two strongest risk factors for twinship are maternal age and maternal propensity to use IVF. Maternal age is highly correlated with education (it often means a mother waited to finish a degree before having children) and our readership is nothing if not eager to use new birth-related technologies. So we should expect to have significantly more twins than average. But in fact we have fewer. This isn’t a giant difference, but I think it supports the hypothesis at least a little.

There are two active prediction markets [1, 2] (that I know of) related to the question of the pandemic’s origins. As Scott noted in a recent ACX post, these markets are not straightforward predictions of whether the pandemic began in a lab or not.

Inline links: Scott Alexander himself

I’ve been suggesting a critique, or waving my hand in the direction of one, but let me tell you how much there is in this book. There’s the introduction to the basic theory of cultural evolution – the psychology that lets humans have cultures and how ideas can transmit themselves down generations. There’s the definition of WEIRD psychology, including dispositionalism (the tendency to explain people’s actions by their innate character), and the tendency to categorize rabbits with cats not carrots; and the fact that even the famous Big Five traits of personality psychology don’t generalize very well beyond the WEIRD countries. There’s a taxonomy of the institutions that help human groups scale up their cooperation, starting with unilineal clans – the basic unit of intensive kinship, and the blind alley that most human societies got stuck in, on Henrich’s account – and including segmented lineages, age sets and premodern chiefdoms and states. (This is a very scientific, comparative approach to anthropology. I would love to hear a debate between Henrich and David Wengrow, whose book The Dawn of Everything, reviewed in ACX here, takes a much more voluntarist approach, starting from the view that there are many ways to organize a society, and that rational collective institutional design is pretty much a human universal.)

Can H-Y antigens explain the other birth order effects found on the ACX survey (and general firstborn advantage in math, physics, etc)? It’s a tempting hypothesis, since math, physics, and the ACX readership are all disproportionately male, and any process which gave people less-male-typical brains would drive people away from these things. But I found that the ACX birth order effect was social and not biological, and a Norwegian team found the same on their own data. Meanwhile, Bogaert’s study found the homosexuality effect was biological and not social. I don’t entirely trust either set of conclusions, but as long as they both stand, they weakly suggest these are different effects.

My poor, fragile, little cognitive engines! These, then, will be the twin imperatives of your life: surprisal minimization and active inference. If your brains are still too small to process such esoteric terms, there are others available. Your father’s ancestors called them Torah and tikkun olam; your mother’s ancestors called them Truth and Beauty; your current social sphere calls them Rationality and Effective Altruism. You will learn other names, too: no perspective can exhaust their infinite complexity. Whatever you call them, your lives will be spent in their service, pursuing them even unto that far-off and maybe-mythical point where they blur into One.

But a parable: when you were born, your mother kissed you. Along with the kiss came a microdose of the BCS3-L1 genetically engineered bacterium. Without any teeth to cling to, it fell into the pit of your stomach and died. But she’ll kiss you again and again, transferring a few more BCS3-LI each time. In a few months, one of the colonists will find an incipient tooth and hang on for dear life. It will fight off competitors, wage epic battles that will determine the fate of the mouth for decades to come. It will win, because its genetic enhancements are pretty good.

15: Ancient Germanic kingdoms used to devise mythical genealogies linking their royal families to Odin. And lots of ethnically-Northern-European people are descended from ancient Germanic kings. Combine these facts, and you can chart the 55-generation line of descent from Odin to Joe Biden. I think this has actually made me 0.0001% prouder to be an American. The bottom of the chart is Joe Biden’s real relatives, and the top is the real mythological line of Anglo-Saxon kings, but is the middle accurate? I notice it traces Biden’s ancestry much further than most credible articles on the subject, which go up to the Taylors at best. But it seems to be drawing off of this genealogy database. If there’s a fake step in there somewhere, I can’t tell where it is [UPDATE: in the comments, The Genealogian identifies the fake steps]

Gene Smith5, $20,000, to create an open-source polygenic predictor for educational attainment and intelligence. You upload your 23andMe results, it tells your your (predicted) IQ. Technology hasn’t advanced to the point where this will be any good - even if everything goes perfectly, the number it gives you will have only the most tenuous connection to your actual IQ (and everyone on Gene’s team agrees with this claim). I’m funding it anyway. Partly this is because there are some things you can use even a very bad IQ predictor for, like studies that aggregate a lot of people’s genetic information. Partly it’s because people are already using closed-source IQ predictors for various things, and I think (ceteris paribus) anything closed source should be open source on general principles. But partly it’s because after this technology gets good, there’s going to be a big debate over whether the public should be allowed to access it, and I intend to win that fight before it starts.

Failure To Replicate Anti-Vaccine Poll

June 14, 2024 · Original source

Here “family” was defined on the question page as including “brother, sister, mother, father, child, aunt, uncle, grandparent, grandchild, niece, or nephew”. This is broader than Pollfish’s “member of your household” but narrower than Rasmussen’s “person you know”. Kirsch and I got similar results for knowing someone who died of COVID - 6.5% vs. 7.5%. But we got very different results for knowing someone who died from the vaccine: Kirsch’s 8.5% vs. my 0.6%. Why? As people love to point out, my survey is a nonrepresentative sample. But as I point out, it’s important to keep track of when that should vs. shouldn’t matter. No matter how weird my readers are, they’re not biologically invincible - they should have side effects at similar rates to anyone else. One possibility is that my readers are very pro-vaccine compared to the general population, so they interpret ambiguous cases in a more pro-vaccine way. I didn’t have a question about vaccine-related views, but it’s no secret that vaccine opponents are more often right-wing, so I looked at questions about politics. Conservatives in general were only slightly more likely (1%) to report vaccine deaths compared to liberals (0.4%). But I had a question where people ranked their support for Donald Trump. Trump supporters had much higher vaccine injury rates (7.5%) than moderates (1.3%) or opponents (0.3%). I couldn’t find much of an effect by gender, education level, or any of the other traditional demographic categories. This doesn’t quite explain the difference between my survey and the others, since my moderates had 1.3% side effect rate, and the Rasmussen moderates had 22%. But it does suggest that there’s room for political beliefs to alter perception of relatives’ vaccine deaths. II. All of this would be much clearer if we could get in there and ask the people who said their relatives died from vaccines what they meant. Most ACX Survey respondents gave me permission to email them. So I emailed the people who answered “yes” to that question and asked for their story. Some details: 5,981 people took the survey

Highlights From The Comments On Tegmark's Mathematical Universe

February 21, 2025 · Original source

Falsifiability doesn’t just break down in weird situations outside the observable universe. It breaks down in every real world problem! It’s true that “there’s no such thing as dinosaurs, the Devil just planted fake fossils” isn’t falsifiable. But “dinosaurs really existed, it wasn’t just the Devil planting fake fossils” is exactly equally unfalsifiable. It’s a double-edged sword! The reason you believe in dinosaurs and not devils is because you have lots of great tools other than falsifiability, and in fact you never really use the falsifiability tool at all. I write a bunch more about this here and here.

Your Review: The Astral Codex Ten Commentariat (“Why Do We Suck?”)

July 26, 2025 · Original source

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.

Inline links: The Control Group is Out of Control, Toxoplasmosa of Rage, Untitled

Complexity of thought – Perhaps the most important feature distinguishing the ACX Commentariat from other, lesser, blogs is that some really smart people comment here and give novel and well-nuanced takes on a topic. If this ever disappeared it would not matter about any of the other three features, because the Commentariat would effectively be dead anyway. To me, these broad categories represent the unique and positive features of the SSC/ACX Commentariat, and the extent to which they are present is a reasonable indicator of comment section quality, especially if they are all present at the same timepoint and that timepoint happens to line up with peak engagement in 2016 (this is foreshadowing). To generate data on the ACX Commentariat, I scraped the comments section of every post Scott has made since 2013. The Old Ones whisper of a blog that existed before even Slate Star Codex, but since I’m not 100% certain we’re encouraged to talk about the older blog (and nobody dates the golden era of Scott’s writing to pre-2013 anyway) I kept my scraping to just the two websites we’re definitely allowed to talk about; Slate Star Codex (SSC) and Astral Codex Ten (ACX). The main points of failure with my scraping were Subscriber-only threads (which my algorithm virtuously refused to read as it wasn’t a subscriber) and battling with the Substack UI to get all the comments to load for me simultaneously on larger threads. Nevertheless, between my incompetent code and the jaunty Substack UI I only dropped a few comments on even very long threads, so I figured the data scrape would be adequate for the use-case I had for it. I then used a bunch more janky code (some written by me, some written by ChatGPT) to try and quantify the levels of depth, freedom, politeness and complexity of each comment. I captured 2460 individual posts, and approximately 1.8m comments. Of the 24,486 unique comment authors, around 40% have made only one comment to the blog. The most prolific poster is the irrepressible Deiseach, at 20,685 contributions. Deiseach is also the only commentor to have made a comment on both the first post in my sample and the last, so has been with the blog a very long time! Only one other commentor has made more contributions than Scott (11,249), and this is John Schilling (11,607). The quality of data on individual users is not great for the ACX era (Substack seems to record missing author data in a few different ways, and sometimes swallow data for no reason) but I’m happy to give the rank ordering of anyone else who cares to know their specific level of clout in this niche community - I myself am the 799th most prolific contributor to the comments section (225 comments). I’m also delighted to share my raw data with anyone interested – the summary statistics per post are here. The scraped comments themselves are about 2Gb so I don’t know where I can host them but if anyone has any ideas (and Scott doesn’t mind) I’ll share them too. I know that some of the post titles seem to have turned into hieroglyphics, but as far as I can tell it is cosmetic only and won’t affect any of the actual data – it is a symptom of a cool hidden feature of Microsoft Excel where it open UTF-8 encoded CSVs in a way that garbles special characters for no particular reason. Considering each of these factors in turn: Depth of engagement with a topic

Inline links: first post, the last, here

This graph shows that around 9% of comments will contain at least one token indicating the comment is discussing a sensitive topic, with a range of about 6% to 14%, disregarding the very early years where small sample size made the data more variable. There wasn’t any one ‘sensitive’ token in particular which correlated exceptionally well with the rise and fall of this 6% to 14%, which implies to me that we have correctly identified a general factor of ‘willingness to discuss sensitive topics’ (or possibly that the peaks and troughs correspond to peaks and troughs in the external landscape – ie specific touchpoints and lulls in the Culture War – which would also be fine for the purpose we’re putting it to). This is an imperfect measure because it only tracks if someone is using a sensitive phrase and not whether they are using it in a heretical way (cf. ‘fifty Stalins’ here). However, I thought in the context of ACX posts the approach was probably reasonable – sensitive phrases are only likely to appear if they are being discussed a lot, and we know from the previous section that discussion depth is high both now and during the 2016 peak engagement period. It isn’t necessarily true that deep discussion implies spirited debate - some political discussions on reddit can go into the thousands of comments without anyone ever actually expressing a counter-orthodoxy view – but I think in the specific context of ACX it is reasonable, because we don’t generally have norms of expressing substanceless agreement. Hopefully, therefore, the changing ratio of socially or professionally sensitive phrases to phrases not included in my dictionary would tell us something about the willingness of the comment section to engage in potentially emotive discussions at any point in time. The relationship of occurrence of these tokens to engagement with the comment section is hard to draw clear conclusions from – although the peak does indeed look to be about 2016 or 2017 the data are noisy, and strongly affected by the choice of words to include in my dictionary. I picked the dictionary before I saw the data, but perhaps a different set of words would have given a different result, especially if I had a better way of identifying sensitive discussions around COVID (‘ivermectin’ was the only COVID-related word I could think of that became politicised in the same way ‘microaggression’ or ‘misgender’ did). Nevertheless, I would say this gives some weak support to the idea that 2016 was a turning point in SSC Commentariat free speech norms (and strong support to the idea that the start of ACX was a low point for discussion of sensitive topics) I include below a few specific sensitive phrases which I thought were interesting. Do note the different scales on each graph. Of particular interest to me is the ‘SJW’ graph, which has a really clear peak at exactly the high point of Commentariat engagement. I will return to this graph later in the review. Politeness

The Fatima Sun Miracle: Much More Than You Wanted To Know

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.

(source) The swirling, colorful sun sounds like the miracle of Fatima. The “tree of life symbol” might be a Purkinje tree, an established entoptic phenomenon. As for the rest, your guess is as good as mine. For what it’s worth, evangelical Christians warn that Demons Enter By Sungazing. This could just be the evangelical Christian tendency to worry about demons being associated with every unusual spiritual practice. But those figures walking out of the lake will haunt my dreams. 6: And I Say, It’s All Right Here’s the most sensible story I can generate for the Sun Miracle of Fatima: There is some previously unknown optical illusion that potentially causes the sun to appear to change colors and spin. This phenomenon is rare and inconsistent, and usually appears only after someone has stared at the sun a very long time. This explains why it’s only reported in the wild by a few weird Redditors who stare at the sun on purpose every day. The appearance of this illusion is somehow modulated by cloud cover. In normal conditions (bright day, no clouds) it’s almost impossible to summon without long periods of sungazing. But when the sun is half-hidden by translucent clouds, the illusion happens much faster. This explains why the Fatima, Ghiaie, Benin City, Necedah, and Lubbock miracles - as well as some of the most impressive Medjugorje cases - all happened just after rain stopped and the clouds were just starting to clear. It also explains why Fatima witnesses say that the sun was “covered in gauze” or “blocked by smoked glass” or “had a diaphanous veil” or “looked like it was seen through a window”. It’s also why, during the most impressive instances of the miracle, people say they can stare at the sun without it being too bright or hurting their eyes. But like koro, the illusion is also modulated by expectations and social priming. Paying attention to the sun, expecting something weird to be there, is much more likely to generate the illusion than catching a casually glance of it. This explains why it is most common during Marian apparitions and other Catholic events full of people familiar with Fatima, and only very occasionally appears to weird Redditors who aren’t specifically looking for it. It also explains why Professors Messeen and Stöckl (who were specifically thinking about Fatima at the time) got better results than earlier scientists (who were observing without preconceptions). At Fatima, the basic illusion, the meteorologic conditions, and the social priming all came together to a point where 80%+ of the pilgrims saw the phenomenon quickly enough that they neither stopped looking nor perceived it as taking unreasonably long. The conditions lasted ten minutes, during which time the sun peeked out from behind the clouds three times; to people who had been staring at the (veiled) sun with their pupils dilated, this looked like the sun suddenly flaring up monstrously large and hurling itself towards Earth (and speculatively, maybe something similar is responsible for the changes in the Filipino video). A small number of mentally susceptible people, already in a vulnerable state because of this apparent miracle, influenced by a process similar to visual release hallucinations, saw additional visions, like the Virgin Mary or the Cross. Some distant witnesses remembered that someone had prophecied a nearby miracle for that day. Because they were not so distant as to have totally different meteorologic conditions, when they looked up at the sky trying to catch the miracle, they saw it too. After the miracle ended, the people who saw it were primed to see it again for the next few weeks - partly because they were looking at the sun expectantly, and partly because they were in a susceptible frame of mind (cf discussion of delusional parasitosis here, panic attacks here, or chronic pain here) - explaining Garrett’s claim that “now everyone sees [the sparkling rotations of the sun] many days and many times”. Even thinking about the miracle served as a form of priming, so further Marian devotions in Fatima and elsewhere became hotspots for miraculous activity. This theory avoids some of the pitfalls of its component parts: I previously said that entoptic phenomena / hallucinations / illusions couldn’t explain the miracle, because normal sungazers don’t report it. This new theory adds modulation by meteorologic conditions and social priming. Absent these factors, the miracle will only occur for a small fraction of sungazers after many minutes spent gazing (producing the scattered Reddit reports). Given these factors, it can occur en masse.

Highlights From The Comments On Fatima

October 24, 2025 · Original source

A nun stated that some people had seen “something” appear in the sun in Torres Novas, also about 12 miles away, though she is not really clear on whether she saw it herself or is just relaying other people’s impressions. I continue to be confused by a pattern in which we have one or two secondhand testimonies from entire towns that supposedly witnessed a dramatic miracle. Ethan then proceeds to make the situation tougher for himself, describing two witnesses from 120 km and 160 km away. But a 160 km circle includes three big cities - Porto, Coimbra, and Lisbon - along with many medium-sized towns and small villages. When we combine this with the evidence from Ghiaie - where it was witnessed from distant Tavernola but not equally-distant Milan - I think these testimonies are more consistent with a few suggestible people saying “Oh, a cool miracle? Yeah, I definitely saw it too” than sightlines that spread through normal geography. I think people were more likely to say this if they were close (and so it was plausible) than if they were very far away (and so it was less plausible), but that this is some kind of gradually declining function, rather than the sharper function you would expect if there were an actual boundary. (one person in central Germany, about 500 miles away, claimed to see the Ghiaie miracle - I didn’t include this on the original post, because it didn’t seem credible, but I think it’s good evidence that sometimes people say non-credible things) I do continue to be confused by the Alburitel stories, which seem much stronger than the others, and perhaps by the Minde story, which is at least in the right place. 4: Heat I don’t think this made it in the post, but during a conversation Ethan answered one of my objections - that any heat warm enough to dry clothes in Fatima would have started fires and explosions closer to the source - by saying that unlike the light (which was visible omnidirectionally), the heat was a ray shot straight at Fatima, which didn’t affect anywhere else. I admit this answers my objection. I won’t even ask for a complexity penalty here, because it makes sense that a just God would try to avoid frying random villages. 5: Ending One objection I raised to Ethan’s not-the-real-sun story was that, when the miracle ended, the fake sun would either have to disappear, or remain in the sky long enough to be seen alongside the real sun. But witnesses reported neither of these two things. Ethan reports one witness who says they saw a fake sun first leave from, then merge with, the real sun. I have that witness statement too - it’s on my list of weirder testimonies that don’t mesh with everyone else’s. The large majority said they only saw one sun. If most people had seen multiple suns, we wouldn’t be having this discussion. If I understand Ethan correctly (which I might not, I’m having trouble interpreting this passage), he thinks that maybe the clouds cleared enough to reveal the real sun right as the fake sun moved into the same position as the real sun, the crowds were temporarily blinded, and the fake sun took advantage of this to disappear unnoticed. 5.2: Later Miracles I claimed that later miracles were obviously not objective-in-consensus-reality. For example, the Benin City sun miracle was seen by people in one field, but not in the rest of the surrounding city of 1.5 million people; the Lubbock sun miracle was seen by something like 50 - 75% of attendees. I said that this suggested the Fatima miracle wasn’t objective either. Ethan objects that there is no reason the different miracles should be implemented the same way, and that maybe Ghiaie was a unidirectional beam of light focused away from Milan, and that maybe Benin City was entirely subjective, but Fatima was omnidirectional and objective. I of course cannot disprove the possibility that God implements the same miracle in different ways at different times; the most I can do here is ask for a complexity penalty. 5.3: Domingos Pinto Coelho DPC was a lawyer and statesman who saw the miracle at Fatima, wrote an article about it, and dropped at the end that the next time he’d encountered similar weather conditions he’d tried staring at the sun again and seen the same miracle. I described it as a powerful testimony in favor of the illusion/hallucination/suggestion hypothesis. Ethan says that “the Portugese historian Costa Brochado cast doubt on the integrity of this report”: The articles of Dr. Pinto Coelho in A Ordem seem to be very much exaggerated. It is difficult to understand the manifest confusion he establishes between the phenomena at Fatima… and the alterations in solar light that he says he saw in Lisbon some days afterward. But in any case the historical value of the articles of the leading Catholic organ is almost nil… We believe that we can declare, after patient research on the matter, that the articles of Dr. Pinto Coelho ought to be read from a political point of view, since their objective was, as the author himself came to declare, to serve as the devil’s advocate As far as I can tell, this is just a historian named Costa Brochado saying he doesn’t believe Coelho. I don’t know why we should trust Costa Brochado, but since we’re bringing in random historians’ unsupported assessments of Coelho’s honesty, here is Father Stanley Jaki: Nobody could doubt that he [DPC] was a man of utter veracity, a point to which no proper attention has been paid in the Fatima literature. There he is all too often ignored and when not, he is dismissed as someone who had an axe to grind on behalf of Church authorities wary of Fatima…in view of Coelho’s unquestionable probity, one has to assume that he saw, with eyes unblurred, what he claimed to have seen, a repetition of the miracle of the sun. He never retracted, however slightly, his claim. As one who in his last hours fervently invoked the help of Jacinta who he came to venerate as a saint, Coelho would have hardly lived with the knowledge that he had intentionally mislead countless readers of his in a matter that so closely involved Jacinta and the other two videntes…Coelho surely must have thought that Rather than keep calling character witnesses, I think it’s more helpful to note that we now have two more testimonies of people who saw the miracle once, then were able to reproduce it under less holy conditions. One is Case One of Nix & Apple, who describe someone who saw the miracle in Medjugorje, then went home to New Orleans and was able to see it again. The other is person #14 on my list of survey responses. I emailed him and asked him to confirm that he was claiming that he could repeat the miracle when the weather conditions were just right. He responded: Yes, exactly. Excluding sunsets, I was able to focus on the sun when it was in a cloudless area of the sky only once (after the pouring rain had just stopped); on all other occasions, the intensity of the light made it impossible to focus on the sun. With translucent clouds, focusing on the sun was easier, and the visual changes (colors, apparent movement) appeared consistently after a few seconds. Even though it wasn’t asked in the questionnaire, I have a hypothesis about the physiology underlying the phenomenon, or at least the parts I experienced. Thinking back to those experiences, I might hypothesize that the intense white light of the sun caused the simultaneous formation of afterimages of different colors in the same area of the visual field. It could be that the visual system, in the presence of conflicting signals, instead of integrating the information by creating a white afterimage, rapidly switched attention from one color to another, creating the alternating colors. If this process occurs unevenly across the afterimage area, different parts of the area will change color at slightly different times, creating the appearance of movement within the area itself. I think the reason this phenomenon is not very common is because there is a narrow window between “light too bright to stare at the sun” and “light too dim for the alterations to appear.” The reason I was able to get these results repeatedly was because I was trying to replicate them, so whenever I saw translucent clouds, I tried to conduct the experiment. With clouds that were too thin I failed, but with clouds that I believe belonged to the Stratus translucidus or Altostratus translucidus category, I succeeded. I would have agreed with this earlier, but it’s awkward to have so many people who say they’ve seen this in a completely clear sky. Very speculatively, there might be some individual variability in the ability of the eye to adjust out brightness, and different people will reach their sweet spots in clouded vs. clear skies. 6: “God is not a man, that He should lie, nor a son of man, that He should change his mind.” Speaking of complexity penalties, I have a broader objection to some of the moves Ethan is making here. If I understand his theory correctly, it goes like this: the miraculous object at Fatima was not the sun. But God put a lot of effort into tricking people into thinking that it was. Even though the object was below the clouds, He made the clouds clear around it at the moment of its appearance, so that it looked like the clearing clouds had revealed a normal above-the-clouds sun. Then, when it was time to remove the object, He made it disappear at the exact moment that the real sun came out behind clouds, so that the crowds would be too dazzled to notice that the object and the sun were two different things. This leaves a bad taste in my mouth, for two reasons: God shouldn’t try to trick people.

But if He does try to trick people, He should succeed. I can’t say either of these two things with confidence. Doesn’t the Biblical God sort of try to trick Abraham into thinking he’s going to have to sacrifice his son? And what is God, anyway? Isn’t the whole world a product of God? Does the existence of mirages in the desert count as “God trying to trick people”? Does that fact that we know there are mirages imply that God failed? Still, Ethan’s take on the “sun” miracle of Fatima seems like an unusually clear-cut case of God trying to trick people and failing, and I’m uncomfortable with it. You can always add more overfitting. God’s goal was for the crowds at Fatima to be fooled, but then for Dalleur (2021) to figure it out, and so He achieved His goal perfectly. Okay. But speaking of overfitting… If I understand Ethan right, Fatima was an objective omnidirectional light show, plus a unidirectional heat ray. Ghiaie was a spotlight-shaped unidirectional lightshow. Benin City was a subjective omnidirectional light show limited to a single field, plus an objective unidirectional heat ray. God implemented all of these miracles in completely different ways. Why? Inscrutable God reasons. This isn’t a terrible answer. People often do things for reasons I can’t explain - if I could predict Trump’s behavior, my stock market returns would be much higher. And surely God, as a being with motives and knowledge far beyond my ken, should be even more incomprehensible. But there was an interesting recent Notes debate about a Bentham Bulldog’s post. BB said that atheists had many problems - how was the world created? how do you overcome skepticism? what happened at Fatima? - whereas theism only has one problem - the problem of evil. Evil is a big problem, but it’s at least nice to only have one. Some of the commenters - and I can no longer find the comment I liked anymore, but don’t take this as an original insight from me - pointed out that this is cheap. If you are an atheist, you need to answer many how questions. How did the miracle at Fatima happen? If you try to explain it with natural laws - for example, gravity - it’s fair for an interlocutor to point out that gravity can’t do that; it can only make things fall. If you’re a theist, you have a free option to convert any how question to a why question. How? Because God did it! Your interlocutor can’t object, because we know God can do anything. But in exchange, you now have a why question - why did God do that, and not something else? The sum of all why question - the fact that the real world doesn’t look like it was optimized for some specific plausible motive like goodness - is the problem of evil. Thus, it is exactly equivalent to all the inconvenient “how” questions you hoped you’d avoided. The commenter sarcastically compared this to an attempt to sweep all scientific anomalies under the rug as “the problem of uncharacteristicness”. How did Fatima happen? “Well, it must have been produced by laws of physics, so there!” But the sun spinning and dancing through the sky is hardly what you would expect from the laws of physics. “Yeah, whatever, that’s just the ‘problem of uncharacteristicness’, we’ve already priced that one in, at least we only have one problem!” This made me more attuned to questions of God’s motives. Yeah, it is kind of weird that God would create the same miracle three different ways, and we don’t know why. Yeah, it is kind of weird that God would try to trick people into thinking a non-sun-object was the sun, then let a few smart people working years later see through the deception. Are these problems of motive exactly as problematic for the theist as 70,000 people seeing the sun do impossible things is for the atheist? My gut answer is no. Should I trust my gut? Dylan: In Defense Of Evan Harkness-Murphy Evan wrote the original response to Ethan, before I got involved in the debate. I was a bit harsh on him, saying that his part about the child-seers was fine, but calling his investigation of the sun miracle superficial and unfairly dismissive. Dylan of Chaotic Neutral writes In Defense Of Evan Harkness-Murphy, and Evan additionally defends himself here. Before getting to Dylan’s post - yeah, I was unfair to Evan (partly this is because my brain has trouble remembering that Ethan Muse and Evan Murphy are two different people). In particular, I described his hypothesis on the child-seers as being that they “confabulated” their visions, a term that Evan took great pains to disclaim in his actual post. I was thinking of a broader definition of “confabulation” that includes hallucination-like phenomena - but Evan was right that if I had read his post carefully, I wouldn’t have used the specific word he said he was against. I mostly just skimmed it to see if he had a really good explanation for the sun miracle thing, then got annoyed when he didn’t. But Dylan has additional complaints. He writes: Evan DID give this miracle the attention it deserved. He spent 18 hours researching and writing his article, presenting much of the same evidence and coming to many of the same conclusions that Scott did, and he did it as an ordinary citizen with a “day job” and in a household that “does not possess a dishwashing machine.” What more could you ask of a skeptical individual!? Unlike myself and the other lazy skeptics, he actually did respect this miracle claim enough to do a proper investigation. And towards the end, yes, he decided to wrap up early […] To criticize Evan’s conduct here in this miracle debate is to set an extremely high bar that cannot possibly be met by the overwhelming majority of the skeptical community. Such exacting standards will ultimately only serve to discourage diligent skepticism like Evan’s and incentivize lazy skepticism like mine. I have two partial defenses of my own actions. First, I think the majority of those 18 hours were spent on the child-seer section, which I acknowledged was good. I didn’t care about that part. To me, the trouble of explaining how three children can say in a convincing and honest-sounding and semiconsistent way that they saw the Virgin Mary is a rounding error compared to the trouble of explaining how 70,000 people can say in a convincing and honest-sounding and semiconsistent way that they saw the sun fall from the sky. But second, I think Dylan is arguing that Evan should get an A for effort. I agree. He put in a lot of work, he adhered to good scholarly principles, and he hit all of the beats that a skeptical explanation is supposed to hit. The only thing he didn’t do, from my perspective, is defuse the fact that the Fatima miracle is extremely creepy, and I have no idea what to do with it, and I can’t fit it into my ontology. Evan’s only attempt to defuse the miracle was that it was a hallucination or illusion or something. This is a reasonable conjecture, but for me it was already priced in - as soon as you hear about a miracle, the obvious next step is “well, maybe it was a hallucination or illusion or something”. I didn’t feel like his piece added anything extra. Generously, some of his tangential points - like that Garrett and Almeida weren’t the perfect skeptics they are sometimes portrayed as - might have defused 1% of my discomfort. I think a reasonable conclusion for this would have been “I’ve rehearsed the obvious arguments for why it is possible to be skeptical of anything, I’ve found some tangential facts that maybe remove 1% of the mystery, but man, I don’t know, this really needs lots more investigation”. My research hardly provided any kind of brilliant omni-solution, but I think that learning about the Ghiaie/Benin/Lubbock/Medjugorge followup miracles and the Redditor testimonies each defused about 15% of my reluctance to accept Fatima as natural, and the fire kasina + Khomeini stuff defused another 10%, to the point where I’m only about 60% as confused and unhappy as when I started. I hope I correctly signposted this level of success/failure to the reader. On Miracles Other responses tried to assert a general point that we should always disbelieve miracles. I. Eugene Earnshaw writes that We Do Not Need To Care About Miracles. If I understand his argument right: there are many examples of anomalous phenomena (eg crop circles) and stage magic (eg sawing a woman in half). When we don’t know how these are done, they seem impossible, and (almost) no amount of armchair reasoning can produce a plausible explanation. But in many cases, we have eventually figured them out - some “white hat” crop circlers explain how they make their seemingly-impossible patterns, and some magicians publish explanations of their tricks. After the fact, we can see how these seemingly-impossible things followed natural law after all. So we shouldn’t worry too much each time we encounter a new miracle that hasn’t yet been explained. Okay, but - suppose that the Pope said “I’m tired of convincing you people the normal ways, I’m going to start blowing up mountains”, and pointed his papal staff at Mt. Everest, and it exploded. And then we asked him to repeat the performance, and he did so as many times as we asked him, again and again. Would we shrug and say “Nothing to see here, I’m sure there’s some reasonable explanation”? If the miracle were sufficiently convincing, we would either believe it, or at least think it pointed at something interesting (maybe the Vatican obtained super-nukes and is hiding them under mountains and choreographing their detonations - but this would be pretty important and very different from “nothing to see here”). Ben Landau-Taylor gives a related answer, reminding us that meteorites used to be dismissed on exactly these grounds. The science of the day didn’t allow for non-planet objects to be in space, so rocks falling from the sky was every bit as weird as the sun dancing and changing colors. “When President Jefferson was told that Professors Silliman and Kingsley had described a fall of stones from the sky at Weston, in Connecticut, he remarked: ‘It is easier to believe that two Yankee professors will lie than to believe that stones will fall from heaven.’” In the end, I think we just get back to regular Bayesianism. We have two hypotheses: First, that the world acts entirely according to natural law. Second, that sometimes it includes divine intervention (or very surprising natural laws that we wouldn’t have predicted beforehand). We start with a high prior on the first hypothesis based on our long history of seeing only natural events. When we see evidence that is more likely on the second hypothesis than the first, we update in favor of it. We should remember that “more likely on the second hypothesis than the first” is full of pitfalls - on the first hypothesis, it’s likely that there will be many skilled fraudsters and stage magicians, so even very strange-seeming anomalies might not be very unlikely under it. Still, at the point where the Pope starts blowing up mountains, maybe you think it’s pretty unlikely that stage magic could accomplish this, and you update a little. II. Omne Bonum makes a different point: there are many possible miracles. Most do not occur. Yes, a few of them do. But can we be sure it’s above the background rate? Even if there are no true miracles, you’ll get one-in-a-million coincidences one-millionth of the time. If you’re not good at accounting for the 999,999 failures - and people aren’t - this will look impressive. Against this, what is the base rate for the sun changing color and dropping out of the sky, at the precise time that child-seers prophecied a miracle would occur? Seems lower than one in a million. Impossible things should never happen. Something as simple as my pen vanishing from my desk, in plain sight, while I am looking straight at it, should completely demolish all of my priors against miracles and make me near-certain that something beyond normal physical law is going on - or that I’m crazy, or dreaming, or something other than just “well it was a coincidence”. III. FLWAB takes on Hume’s argument against miracles (see also Kenny Easwaran here), which - sorry, I realize it’s suspicious to say this about a famous philosopher - is extremely bad. Hume argues that a miracle is a violation of natural law. And a natural law is something that is always true. But since it’s always true, it can’t be violated. And if we eventually confirmed that it was violated, then we were wrong about it being a natural law. Which means its violation wasn’t even a real miracle anyway. This seems to be a purely semantic argument. We know that the Red Sea usually stays in one place. But suppose Moses lifts his staff and parts the Red Sea, and that all of this is very convincing (we witness it personally, we measure the sea with various instruments, etc). I think Hume would have to say that we have disproven the natural law “the Red Sea usually stays in one place” - but only in favor of a new natural law “the Red Sea stays in one place except when Moses raises his staff”. And since we have never observed a violation of this new natural law, no miracle has occurred! Against this, we can call the way things work 99.999% of the time, when God isn’t acting directly, and when everything is proceeding via predictable material patterns “natural law”, and the very rare deviations that only occur in the presence of God or other extremely holy figures “miracles”. If for some reason you hate that terminology, come up with a new word, “shmiracle”, for the abnormal phenomena that only occur secondary to God’s direct intervention, and then we can argue whether shmiracles exist. IV. Why am I insisting on this so hard? This question of miracles is no different from every other question, where confirmation bias is a part of normal Bayesian reasoning. If you believe that vaccines don’t cause autism, then any given study showing that they do is likely to be a fraud or a mistake - especially given the history of such frauds, and the political pressures for producing them. But you gained your belief that vaccines don’t cause autism through some normal amount of evidence, and if the evidence that they did cause it ever become truly overwhelming, you would switch sides. The key skill of rationality is to know when to update your beliefs how much. These arguments feel like sleights-of-hand arguing that you can avoid ever updating on this question. I don’t think Bayesian reasoning provides an excuse for this. I think some of these arguments attempt to make an objection that the prior probability of miracles is zero, and so no matter how much evidence you get, you can never update towards them. But the prior probability of miracles isn’t zero unless either the prior probability of God’s existence is zero, or the probability that God intervenes in the universe is zero. I don’t know any infinitely-convincing argument for either of these points, so I think miracles have a prior probability above zero, which means we have to treat them the same as any other hypothesis. Yes, we will need many extra guardrails and cautions and good heuristics to prevent ourselves from getting bamboozled by the pitfalls that lurk in this area in particular. But that’s true of everything! You also need extra guardrails and cautions and heuristics to prevent yourself from getting bamboozled by scientific studies! There’s no substitute for doing the work. Actual Highlights From The Actual Comments Josh (blog) writes: I’d add that we have at least one verified case where a sun miracle was occuring, and an actual group of fedora wearing atheists were present with a modified telescope, and did not see anything interesting. >> “At the Conyers site, the Georgia Skeptics group set up a telescope outfitted with a vision-protecting Mylar solar filter, and on one occasion I participated in the experiment. Becky Long, president of the organization, stated that more than two hundred people had viewed the sun through one of the solar filters and not a single person saw anything unusual (Long 1992, 3; see figure 1).” https://centerforinquiry.s3.amazonaws.com/wp-content/uploads/sites/29/2009/11/22164423/p14.pdf Funny, but they don’t provide information like whether people were seeing sun miracles at the exact moment the telescope was being used, or whether anyone who could see a sun miracle without the telescope switched to using the telescope and then it stopped. They just say they brought a telescope to a Marian site where some people had seen sun miracles at some point. Even if they clarified that some people had used the telescope while seeing a sun miracle and had it immediately stop miracle-ing, I don’t think this would update me very much. We know it’s not the real sun (Ethan says fake sun, I say subjective phenomenon), and we know the non-Fatima miracles aren’t objective (Ethan says only Fatima was objective, I say none of them were objective). John Schilling writes: Twenty-nine *thousand* words on this subject, and none of them are “unidentified”, “flying”, or “object”. Well, OK, there are a few uses of that last, but in the strained phrasing of “UFO-like object”, as if we are preemptively discounting the possibility that sun miracles are actually UFOs. Sun miracles are actually UFOs, full stop. Not “flying saucers”, not “alien spaceships”, maybe “divine miracles”, but definitely “unidentified flying objects”. We invented that last phrase for a reason, and this is exactly that reason. Which means, the thing I learned from this is that the younglings have completely forgotten all that was learned in the Before Times about UFOs. And that, in this context, Scott is a youngling - UFOs seem to have faded from pop culture in the 1990s. Thanks for making me feel old, Scott :-) With the benefit of age and experience, I read the first few paragraphs, made the tentative conclusion that this was almost certainly [see section 6], but figured Scott wouldn’t be doing this deep a dive if it was that simple. And here we are. It probably is just that simple, and now we can back that up with a fairly exhaustive look at the alternatives. For which, unironically, thank you Scott. It’s good to sometimes double-, triple-, and quadruple-check the obvious conclusion. But for those of us who grew up in the 1980s, who were “rationalists” when rationalism hadn’t been invented and we had to call ourselves “skeptics”, UFOs were as important a subject of rationalist/skeptical inquiry as is AI risk today (and for about the same reason). People learned an awful lot in those days. One of those things is that most people don’t spend much time really looking at the sky and will consistently fail to recognize even slightly-unusual phenomena, like the sun partially veiled by clouds. And the other, more important thing is that when presented with an image they don’t recognize, people will very predictably see what their culture has taught them to expect to see. In 1880s-1890s America, any weird thing in the sky was clearly a fantastic airship, built by some mad scientist out of a Jules Verne novel, and was perceived with a wealth of surrounding detail all aligned with that model. 1950s-1980s America, the same things were clearly “flying saucers”, fantastic alien spaceships piloted by little green or grey men, with the same level of impossible detail. And anywhere you’ve got ten thousand devout Catholics fervently hoping to see a Miracle involving the Sun, and the weather makes the sun look a bit wonky... For an old-school skeptical experiment at understanding this effect, https://centerforinquiry.s3.amazonaws.com/wp-content/uploads/sites/29/1980/04/22165441/p34.pdf TL, DR, a gathering of UFO enthusiasts expecting to see a flying saucer in the night sky, are presented with thirty seconds of a monochromatic point source of light at ground level, stationary and unchanging except for one brief interruption. What is perceived, is an object high in the sky with finite angular size and geometric shape, of multiple colors, and conspicuously moving, all consistent with the pop-culture concept of a flying saucer and not some prankster with a spotlight. I considered discussing the UFO angle (the section heading would have been “Virgin Galactic”), but in the end I couldn’t justify it. Yes, the phenomenon is trivially a UFO (in the sense of a thing in the sky we don’t understand). But does this help us? When I think of UFOs, I think of people arguing about whether something was the planet Venus, or a weather balloon, or aliens. But Fatima obviously wasn’t Venus or a balloon (though, uh, see here for a dissenting take). And if it was aliens, you’d have to explain why they pretended to be the Virgin Mary and discussed a bunch of Catholic inside-baseball with a trio of child-seers for several months. So what’s left? When I asked John, he answered: UFOs, are just people seeing something they don’t understand and trying to interpret it by an overweighted, culturally-transmitted prior. Which differs from culture to culture. And that’s something we know a lot about. Which you seem to have independently rediscovered, but I can’t help thinking you’d have got there a lot faster if you’d had a proper map of the territory. A map which includes no aliens outside of the imaginary sort. Maybe one way to rescue the UFO connection is to say that there’s so much weirdness that we should be less willing to take any given example of weirdness on its own terms. I asked in the comments for other examples of miracles as compelling as Fatima. People suggested some of the better-verified reincarnation accounts, some of the better-verified UFO sightings, and some of the more spectacular psi phenomena. I don’t know if these are all exactly as strong as Fatima, but I think many of them are closer to Fatima than to the traditional skeptical conception of an alcoholic liar asserting with zero evidence that he dun saw dem aliens one night. When viewing all of these anomalies as a gestalt, we can go four different directions: Individualized natural explanations. The UFOs were swamp gas and weather balloons. The reincarnation stories are toddlers who are naturally gifted at cold reading. Fatima was entoptic phenomena. Sea serpents are really big oarfish.

…with some representations being even more suggestive: Nikita Sokolsky (blog) writes: » Our best source for witness testimonies is the Documentacao Critica de Fatima [...] The rest is available only as physical books, $15 + shipping each. Somebody should buy the books, scan them, machine translate the testimonies, and put the translations online. The most important is Volume III I’ve ordered Volume III - though shipping anywhere outside Portugal cost $48 (not surprising for a 639 page book, I guess). They promise delivery by Oct 12th. » There are a few articles about solar retinopathy in the context of Marian shrines that I couldn’t access, including at least Nix and Apple (1987) and Campo et al (1988) Emailed you both. Thank you, Nikita! I’ve uploaded Campo here, and Nix & Apple here. Campo is only a few paragraphs, and contains little of interest if you’ve read the original post. Nix & Apple profiles several cases in New Orleans, including a pilgrim who saw the miracle in Medjugorje and then went home and saw it again in New Orleans, and a second person who skipped Medjugorje and saw it in New Orleans with no previous exposure. There was also an interesting case of someone who stared at the sun for 15 minutes with no injury, then tried again for 15 seconds and did get an injury that time. My days of not understanding the function mapping sungazing length to injury probability are definitely coming to a middle. The eye doctors who wrote the article only say that “Evidence suggests a great individual variation in the susceptibility for developing solar retinopathy, as the cause of the lesion is felt to be a photochemical injury rather than a thermal injury of the retina and retinal pigment epithelium.” The Ghiaie translations are in a form that makes them harder to upload, but there are about a dozen which contain descriptions of a sun miracle, all of which match the Fatima testimonies closely. The one I found most interesting was a monk nearby, who originally doubted the apparitions; he was in his monastery doing normal work when he saw the sun miracle, which included a beautiful white cross appearing in the sky. Other monks saw it too. The next day, he says that a secular newspaper claimed local astronomers had found some kind of ice crystal phenomenon responsible for the event, but he didn’t believe it. He didn’t clarify exactly where this happened (though his address was Castelnuovo Don Bosco, about 80 miles from Ghiaie) or when (though the testimonial implies it was at the same time as the Ghiaie miracle). Main Conclusions And Updates I’m impressed by the fire kasina correspondence, but the difficulty in explaining how everyone immediately became an expert fire kasina meditator is almost as tough as explaining the original miracle.

Yes, voters react positively both to candidates “over the age of 50” and candidates “under the age of 50”. Just don’t run 50 year olds! 16: I previously blogged about how embryo-selection company Nucleus appeared scammy. Sichuan_Mala looks deeper and agrees they seems scammy. Besides what I found, she finds several errors in the white paper, apparently fake customer reviews, and an accusation of IP theft from competitor Genomic Prediction. She also accuses them of plagiarizing competitor Herasight’s work, although it’s a bit subtle and I don’t know enough about field norms to know whether this is a case of flattery-by-imitation or totally out of bounds. A Nucleus researcher responds to the scientific allegations here, saying that the “plagiarism” was just convergent methodologies. And Nucleus CEO Kian Sadeghi goes on the TBPN podcast here to rebut the business allegations, saying that the customer reviews are real although some photos were changed for privacy reasons. There’s an appearance/facedox by fellow Nucleus skeptic Cremieux Recueil, although Kian declines to debate him directly; you can see Cremieux’s postmortem of the episode here. My opinion is that as potential customers, you are under no obligation to care whether the company plagiarizes papers or fakes reviews, but you should care about whether their genetic tests are good, and I continue to think they’re not. Their old competitor Genomic Prediction is cheaper, and their new competitor Herasight has more powerful predictors, so you’re excused from having to have an opinion on this, and should just use someone else’s product. Related: Gene Smith’s rundown of the pros and cons of every company in the embryo selection space (X). 17: And related: a Herasight client describes her experience with embryo selection, and her feelings upon the birth of her selected child. 18: Lars Doucet, guest author of several ACX posts on Georgism, reviews The Land Trap by Mike Bird. “Land is a big deal, and always has been. [But] land has only recently been financialized. Financializing land causes ‘the land trap’ . . . [where] land slowly sucks up all your economy’s productivity, inflating a dangerous real estate bubble that eventually pops, leaving disaster in its wake”. Also, “Fiat currency isn’t backed by nothing, as commonly supposed, but by land.” 19: New research analyzes Hitler’s DNA. Findings: he had Kallman Syndrome, a rare disorder of sexual development associated with low testosterone, micropenis, and small testicles (ironically, the WWII song about Nazi sexual inadequacies only accuses Goering and Himmler of this, but lets Hitler off). Contra galaxy-brained rumors, he did not have any Jewish ancestry. And he had “very high scores - in the top one percent - for a predisposition to autism, schizophrenia and bipolar disorder”. When I wrote this post, a reader asked me what it would look like for someone to have high propensity for both autism and schizophrenia at the same time. Well . . . 20: The wealth of cities (h/t @StatisticUrban): 21: Update on Tech PACs Are Closing In On The Almonds: pro-AI safety politician Alex Bores announced his candidacy for Congress in New York. As expected, the A16Z pro-AI PAC announced a “multibillion dollar effort to sink [his] campaign” (wait, multi-billion on one candidate? is that a typo?) This doesn’t seem to be going very well for them so far. Bores has masterfully leveraged (X) the unprecedented opposition from Big Tech into a selling point. …and raised $1.2 million on his first day, breaking fundraising records (I was told this was because of pro-AI-safety EAs, but others credit AIPAC and the Israel lobby). And most recently, Jami Floyd, one of Bores’ opponents and a possible beneficiary of anti-Bores spending, has condemned it (X) and demanded that the AI industry stop trying to help her. Impressive work from everybody. Related: New $50 million pro-AI-regulation SuperPAC, I assume EA-linked but have no special knowledge. 22: Related: Pre-emption is when Congress blocks states from making legislation on a topic, saying it will decide all the laws itself. The states have signaled willingness to regulate AI pretty hard, so Big Tech has been pushing for AI pre-emption to (in their opinion) prevent an overly complicated patchwork of regulations, or (in their opponents’ opinion) shift everything to a Republican Congress that will drop the ball on regulation entirely. After their first attempt in June was defeated by a coalition of anti-tech liberals and anti-tech conservatives, we discussed (1, 2) the effort by moderates on both sides to create a compromise proposal which pre-empted state laws but guaranteed good federal regulation on important topics. The most recent news is that extremists sidelined the moderates and tried to slip a hardline preemption deal with no compromises into the National Defense Authorization Act, a defense budget bill which is notoriously secretive and hard for the public to learn about. This didn’t work; some of the same coalition, plus a group of Republican state legislators including Ron DeSantis, pressured the GOP to drop it. The next battleground is a potential Trump executive order; although Trump cannot constitutionally ban states from regulating AI, he will threaten them with various consequences like lawsuits or withdrawal of federal funding. The buzz in the policy circles I’m in is that this might backfire; blue state politicians love starting fights with Trump in order to look tough to their blue state electorates. No, no, please don’t give me headlines like “TRUMP CONDEMNS GAVIN NEWSOM FOR TRYING TO PROTECT CALIFORNIA’S CHILDREN FROM AI SLOP”! Anything but that! 23: Related: Trump has decided to sell some of America’s best AI chips to China, supercharging their AI development and crippling ours. The most charitable read is that his administration doesn’t really believe AI matters so they think it’s fine to forfeit it for short-term gain; the least charitable that it’s downstream of the companies involved paying Trump enormous bribes in hopes of exactly this outcome . We’re headed for the dumbest possible world, where we sacrifice our chance to thoughtfully address AI’s social impacts because “tHaT wOuLd mAkE uS lOsE tHe rAcE wItH ChInA”, then throw away the race with China in one fell swoop by handing them our technology for no reason. Shame on everyone involved, especially the people who shout over any discussion of safety with “bUt ChInA” yet have stayed totally silent about this. Our best hope now is that China refuses the chips, either because they want to privilege their own tech companies, or because they think we can’t possibly be this stupid and it must be some kind of spy plot. 24: Related: how the American public’s opinions on AI are changing (from David Shor, h/t Daniel Eth on X): If this is to be taken seriously, AI is already a bigger political issue than abortion, climate change, or the environment. I fail my 2023 prediction that there was only a 20% chance this would happen by 2028. 25: Related: Bernie Sanders in The Guardian: “There is a very real fear that, in the not-so-distant future, a super-intelligent AI could replace humans in controlling the planet.” The Left has a complicated relationship with existential risk from AI: they really hate AI, which in theory should push them towards yet another reason to be against it. But they hate AI so much that they need to believe every negative thing about it at the same time, and one of those negative things is that it’s just a scam and will never work, and this naturally pushes against being concerned about x-risk. But as AI improves, will the “just a scam” position become less tenable, shunting the associated psychic energy into other reasons to hate AI (including x-risk concerns)? 26: Qualia Research Institute has released a video describing some of the work they’ve been doing the past year - The Oscilleditor: An Algorithmic Breakthrough for Psychedelic Visual Replication (1080p•⚠️SEIZURE): 27: Jesse Arm (X): “A majority of American rabbinical students are now women. Most are also LGBTQ. That includes Modern Orthodoxy. Remove Modern Orthodoxy and the numbers climb even higher.” Clergy have always served as spiritual counselors; as religions liberalize and other roles become less important, the therapist role starts to predominate. But 75% of therapists in the US are female; at the limit of liberalization where clergyman = therapist, we should expect the same gender ratio. 28: The latest news on the COVID origins debate: scientists find a naturally-occuring bat coronavirus with a COVID-like furin cleavage site. This is a point in favor of the natural origins hypothesis, since the second-best argument for lab leak was that COVID’s furin cleavage site was too strange to evolve naturally. But I think arguments that lab leak has “fallen apart” are premature: the best argument (COVID emerged only a few miles from the biggest coronavirus gain-of-function lab in the Eastern Hemisphere) remains strong. I update from something like 95% chance it’s natural to something like 96%, but not 99.99% or anything. And here’s a lab leaker arguing that COVID’s furin cleavage site is out-of-frame and so still more unnatural-looking than the one on the recently-discovered bat virus. 29: Nicholas Decker (econ blogger, famous for his controversial autistic takes and Secret Service visit) has a dating doc. Most interesting section is the one about children: he wants to have them, but doesn’t think they should be genetically related to him. From here: If this appeals to you, you can find his contact info on the document. Related: Governor Jared Polis of Colorado is a fan of Nicholas Decker and Richard Hanania. 30: Matt Yglesias comes out as aphantasic (unable to see images in his “mind’s eye”). He says that contra the usual perspective that frames this as a deficit, he finds it helpful. For example, once he got assaulted, and he remembers on an intellectual level that it happened, but since “I wasn’t taking pictures of myself getting kicked in the head so, as far as I’m concerned, it’s like it happened to someone else” (Matt usually has good instincts, so I’m surprised he uses an example which will be such catnip to his conservative critics). He thinks it makes him a better reasoner / statistics blogger / effective altruist to be able to “get a statistically valid view of the situation, not overindex on the happenstance of your life.” For what it’s worth, I’ll give my contrary data point - I think of myself as a reasoner / statistics blogger / effective altruist in a pretty similar vein as Matt, but AFAICT my visual imagination is totally normal; if other people are having their emotions yanked around by vivid images, that’s a skill issue. 31: Lakshya Jain in The Argument: The COVID political backlash [to the Democratic Party] has disappeared. Despite the narrative, polls show that voters don’t favor or disfavor either party over COVID, mostly still think school closures were necessary, and are about evenly split on vaccine mandates. I guess I can’t disagree with this poll - it seems well-done - but I still wonder whether something is being missed. Maybe it didn’t make the ~50% of voters who are naturally liberal desert the cause, but it energized conservatives in a way that might otherwise not have happened? Related, from Rob Wiblin on X, on balance Britons think the government response to COVID was not strict enough. 32: Related: Back when neoreaction was a big deal, I occasionally discussed posts by neoreactionary blogger Spandrell of Bloody Shovel. If you’re wondering what happened to him, you can read his 2024 Post-Mortem Of Neoreaction here, where he discusses how he fell out of love with the movement (warning: he has not fallen out of love with racial slurs). As a former fascist sympathizer, I can see why [fascism is on the downswing]. The allure of fascism in 2024 is much, much diminished. For a few reasons. A big one was COVID. See, the point of fascism is that Collective Action is necessary to have nice things. We need a strong government committed to the good of the people. Yarvin showed his preference early when he started his new Substack by quoting Cicero’s phrase “Salus populi suprema lex”. The health of the people is the most important law. Cicero wasn’t a fascist of course, nor is Yarvin really; a big point of fascism is to narrowly define the populus as an ethnic group with demonstrable ties to blood. That makes the government’s ties to the people stronger, increasing their commitment to do Good Collective Action. Which is important. Very important. A lot of good things can come of intelligently done Collective Action. Fascist Italy made the trains run on time. Nazi Germany fixed the terrible Weimar economy. East Asian countries are all effectively fascist states, if with less ideological baggage (yellows just aren’t like that), and they are all nice, clean, safe places with healthy economies. Fascism is not a panacea but it works, when you let it. Strong government can be pretty neat. So why is strong government less appealing these days? Well, COVID happened. And our governments were pretty damn strong in dealing with it. They made strong laws and enforced them. And what did they do with their power? Absolutely retarded shit. They destroyed the world economy and made 95% of people completely miserable for 18 months. Up to 3 long years in some places. Again, as an Orient enjoyer I was very sympathetic of strong effective government. My life has been pretty cozy thanks to it for the past decades. But after seeing boomers, hypochondriacs, and menopausal women take the reins and use it against healthy people, I’m fucking done with strong effective government. Fuck that shit, I’m out. I don’t want to see strong effective government ever again. I was very lucky that I was out of China in November 2019. It was a fluke really. I moved to the Golden Triangle after that and the law of the jungle was much, much nicer during the Doctors Plague of 2020-2022. But I spent a few months in Europe during the time and man, that was brutal. Not just seeing how retarded governments were; the level of compliance by the people was so disheartening. Imagine being a sincere fascist and seeing your people behave like that. These are my people? My Volk? Am I supposed to sacrifice life and limb for the salus of this populus? Fuck that. Let them cook, they deserve everything that’s coming to them [...] Is there a way to make the body healthy again? I do think so. I think there’s still place for a successor right wing ideology which is neither Christian fundamentalism or robot worship. And it will happen; but it won’t happen on Twitter. Maybe it can happen on Urbit, or right here in this site. I have some ideas myself, and I invite you to join me and build this together. It would be funny if the solution to the paradox Jain highlights was that for every time a COVID lockdown turned a liberal into a conservative, it turned one fascist into a moderate, for a net rightward shift of zero. 33: Also from an Argument poll: In a hypothetical Presidential matchup, Gavin Newsom beats JD Vance 54-46. I’m split between the usual heuristic of ignoring any polling more than a year before an election, and the fact that this is a remarkably big lead for polarized 21st century America. 34: Jerl wades into the David Hume on miracles debate. 35: AI Teddy Bears: A Brief Investigation. The good news is that your child’s AI teddy bear is hard to jailbreak and probably will not tell them where to find guns: The other good news is that somehow they don’t charge a subscription, which makes them a way to get usually-subscription-only AI models for free. How is this possible? “[The most likely hypothesis is that] Witpaw is an adorable piece of spyware and he’s selling my data to the CCP”. 36: This month’s anti-people-named-Sacks content: NYT on Trump AI czar David Sacks’ conflicts of interest; New Yorker on whether neurologist Oliver Sacks used his case studies to work through his own issues rather than presenting them accurately. [EDITED TO ADD: I originally framed it this way as a joke, but on further research I think David and Oliver are related. Wikipedia says that Oliver was first cousins with Israel statesman Abba Eban, and that Abba Eban was born to Lithuanian Jewish parents in Cape Town. David Sacks’ bio says he was born to Jewish parents in Cape Town, and this article specifies that they were Lithuanian. I doubt there were too many Lithuanian Jewish families named Sacks in mid-1900s Cape Town, so sure, related!) 37: Orca Sciences: There Has To Be A Better Way To Make Titanium. Titanium is a great metal - strong, light, and tough. If we had cheap titanium, it could revolutionize manufacturing the way cheap steel and aluminum did in previous eras. So why don’t we? Not because titanium is rare: it’s “the 9th most common element in the earth’s crust”. Rather, it’s very complicated and expensive to extract from its ore. Some kind of breakthrough in titanium extraction processes always seems tantalizingly close, but has never quite materialized. Is there any hope? 38: If Asians Are Lactose Intolerant, Why All The Milk Tea? Lactose intolerance has confused me for a long time - 23andMe tells me that I’m lactose intolerant, but I drink milk regularly without problems, so what’s up? This post’s answer: lactose-intolerant people who don’t usually drink milk will get sick if they start suddenly. Lactose-intolerant people who drink milk regularly since childhood develop gut microbiota that can digest milk, but which demand an expensive “tax” in calories. Lactose-tolerant people will always be able to digest milk and absorb all the calories themselves. 39: How do different majors change college students’ political beliefs? No surprise that the humanities and social sciences shift people left; no surprise that business and economics shift them right. I was a little surprised that engineering shifts people right a little, and that Education of all things shifts people right (albeit only slightly). How is that even possible? Are these people coming in as Mao Zedong and leaving as “only” Leon Trotsky? Also, Political Science is exactly neutral, lol. [EDIT: I misunderstood, they’re using natural sciences as a zero point, this is a reasonable choice but slightly changes the interpretation] 40: Kindkristin: Language models improved my mental health. 41: More floor employment, from the WSJ (h/t @LaocoonofTroy): Big Paychecks Can’t Woo Enough Sailors For America’s Commercial Fleet: “Straight out of college, graduates from the country’s maritime academies can earn more than $200,000 as a commercial sailor, with free food and private accommodations... Despite the pay and perks, maritime jobs go begging, and it is raising national-security concerns.” Other selling points include “six months vacation, live wherever you want, and you’re serving the nation” and onboard “gyms, connectivity, and cuisine”. The catch is that you have to be at sea for months at a time. 42: Study (h/t @KierkegaardEmil): there was minimal “learning loss” from COVID school closures, best estimate is “0.02 standard deviations per 100 days of school closure”. I correctly predicted this back in 2021, but I also wrote in March of this year about how there’s been a general decline in NAEP scores since then. It seems like maybe a student having their specific school closed for longer than other schools didn’t hurt them, but some sort of general cultural change, maybe related to COVID, did hurt. 43: Sam Bankman-Fried’s mother on why she thinks his trial was unfair. SBF is appealing his conviction and will probably be making some of these same points in court. Can’t find a prediction market directly on the appeal, but this one says only 15% chance he serves under 10 years, this one says 15% chance of a Trump pardon, so it doesn’t seem like there’s much room for him to be freed (or get a significantly shorter sentence) on appeal. And Wired says that only 5-10% of appeals like these succeed. 44: Related: Trump pardons Juan Orlando Hernandez, former Honduran president extradited to the US for narco-corruption. Some sources are trying to find a Prospera angle - Prospera and other ZEDEs were approved under JOH’s administration, and the Prosperans seem to have good MAGAworld connections - but I don’t think this is their top priority, and I don’t know if it requires much explanation for Trump to be pro-right-wing Latin American politicians convicted by the Biden administration. More interesting is that apparently JOH and SBF were cellmates (X), “SBF spent extensive time helping JOH with trial prep” and SBF told an interviewer that “Juan Orlando is the most innocent prisoner I’ve met, myself included.” ChatGPT is not impressed with the Trump/SBF case for JOH’s innocence. Related: JOH’s conservative party on track to win this month’s extremely-close Honduran elections, great news for Prospera if it happens. 45: The “100 Above The Park” building in St Louis (h/t Bobby Fijan on X): 46: The death toll of the ongoing Sudan genocide has risen to about 150,000. Nicholas Kristof writes that the world has once again failed to prevent atrocities, and argues that the most important point of leverage is pressure on the United Arab Emirates, which is arming the genociders. Sam Kriss also writes about the situation in The World’s First Matcha Labubu Genocide, but is unimpressed with Kristof’s take: Sudan is passed over in a deeply uncomfortable silence. The absolute most you can do is blame the Emiratis. From what I’ve seen, more people seem to be appalled at the UAE for its frankly marginal role in arming the RSF than at the RSF itself. This is the approved way of understanding any inscrutably indigenous foreign conflict: you just worm out any third-party involvement and then act like you’ve solved the whole thing. I side with Kristof here, for reasons that Sam himself touches on later in his piece, in a section comparing Darfur with Gaza. It would be very easy to make people care about Darfur again. All it would take is a loud, vocal contingent of RSF apologists in the Western media. I agree, but would frame it less cynically: the reason Westerners pay attention to Gaza is that there’s a lever to push: not only does America support Israel, but many of their friends support Israel, so they can imagine convincing America or at least their friends to stop, and at least feel like there is some remote chance of making a small difference (and in fact, Trump getting mad at Israel and deciding to pressure them was decisive in effecting the cease-fire). On the other hand, we don’t have many levers to affect ethnic Baggara in the Rapid Support Forces of Sudan, so it doesn’t really feel useful to write blog posts arguing that they should stop; obviously they should stop, nobody disagrees with this, and it goes without saying - so nobody says it. But the US does support the UAE, and many of our friends like the UAE or at least go there on vacation, so maybe it’s possible to have make some small difference by embarrassing them. 4D chess take is that Sam Kriss agrees with all of this, but “loudly” and “vocally” argued against it to give people like me a hook to write about this genocide with, in which case I thank him for his sacrifice. It would also be nice to be able to donate, but I don’t know who to trust in the region - other than Doctors Without Borders, who are usually pretty good. 47: The AI Futures Project (group of AI-will-be-fast intellectuals) and the AI As A Normal Technology team (group of AI-will-be-slow intellectuals) wrote an adversarial collaboration in Asterisk explaining what they agree on, for example: That there’s an important distinction between existing AI and “strong AGI”

This is the approved way of understanding any inscrutably indigenous foreign conflict: you just worm out any third-party involvement and then act like you’ve solved the whole thing. I side with Kristof here, for reasons that Sam himself touches on later in his piece, in a section comparing Darfur with Gaza. It would be very easy to make people care about Darfur again. All it would take is a loud, vocal contingent of RSF apologists in the Western media. I agree, but would frame it less cynically: the reason Westerners pay attention to Gaza is that there’s a lever to push: not only does America support Israel, but many of their friends support Israel, so they can imagine convincing America or at least their friends to stop, and at least feel like there is some remote chance of making a small difference (and in fact, Trump getting mad at Israel and deciding to pressure them was decisive in effecting the cease-fire). On the other hand, we don’t have many levers to affect ethnic Baggara in the Rapid Support Forces of Sudan, so it doesn’t really feel useful to write blog posts arguing that they should stop; obviously they should stop, nobody disagrees with this, and it goes without saying - so nobody says it. But the US does support the UAE, and many of our friends like the UAE or at least go there on vacation, so maybe it’s possible to have make some small difference by embarrassing them. 4D chess take is that Sam Kriss agrees with all of this, but “loudly” and “vocally” argued against it to give people like me a hook to write about this genocide with, in which case I thank him for his sacrifice. It would also be nice to be able to donate, but I don’t know who to trust in the region - other than Doctors Without Borders, who are usually pretty good. 47: The AI Futures Project (group of AI-will-be-fast intellectuals) and the AI As A Normal Technology team (group of AI-will-be-slow intellectuals) wrote an adversarial collaboration in Asterisk explaining what they agree on, for example: That there’s an important distinction between existing AI and “strong AGI”

The Pledge

December 17, 2025 · Original source

Unless you’re a genius or a saint, your money is the strongest tool you have to change the world. 10% of an ordinary First World income donated to AMF saves dozens of lives over a career; even if you’re a policeman or firefighter, you’ll have trouble matching that through non-financial means. Unless you’re Charlie Kirk or Heather Cox Richardson, no amount of your political activism or voting - let alone arguing on the Internet - will match the effect of donating to a politician or a cause you care about. And no amount of carpooling and eating vegan will help the climate as much as donating to carbon capture charities.
