You don't have to believe them if you don't want to. But this is a pretty impressive example of decentralized expertise weighing in on important inputs to a policy question. Should we hold human challenge trials or not? Well, if we don't, an extra 50,000 people or so will die. You can do this with any question. How much will global temperatures increase if we (do/don't) rejoin the Paris Agreement? How much will British GDP be in 2025 if there (is/isn't) Brexit? How many people will get shot by cops next year if we (do/don't) go ahead with some defund-the-police plan?
Mantic Monday: Grading My Trump Predictions
April 19, 2021 · Original source
- Predicting that Marine Le Pen would not be elected President of France. A lot of people who overupdated on Trump and Brexit decided that polls didn't work anymore and the far-right would win no matter what the polls said, and they bought her up to a price much higher than her numbers justified. I decided Le Pen's polls were much worse than Trump or Brexit's and I was comfortable assuming the polls at least kind of reflected reality, so I bet against her and made about $100.

Your Book Review: Public Choice Theory And The Illusion Of Grand Strategy
June 24, 2022 · Original source
The press should include Tetlock’s superforecasting/prediction markets when reporting the forecasts by the military and national security bureaucracy at public interviews, official reports, and congressional testimony 7. Conclusion And Further Readings Gordon Tullock, one of the founding fathers of public choice theory who coined “rent-seeking”, has always wished for a book like this, and now it exists. It is clear to me that Hanania’s public choice model should usurp the conventional unitary actor model, and any scholar who insists on American grand strategy is deluding themselves. The book hasn’t been reviewed by mainstream outlets (which probably only reviews “pop” nonfiction), but have been unanimously praised by scholars in adjacent fields: Steven Pinker praised it as “cynical but probably accurate”; Robin Hanson was “quite impressed”, Byran Caplan, whose work The Myth of the Rational Voter was cited extensively by Hanania, praised it as “eye-opening”; Tyler Cowen praised the book as impressive in spite of finding Hanania’s view to be more sceptical than his own — a sentiment I share after reading about the East Asian economic miracle (the greatest anti-poverty program in history) facilitated by American intervention in How Asia Works (another contrarian economics-related work I’ve reviewed). Russian Invasion of Ukraine At the time of writing, Russia is invading Ukraine, so it is interesting to see how well the public choice model’s predictions fit. Indeed, the unitary actor model can describe autocratic states to some degree — to understand Russia we only have to get into the head of Putin (the model still falls short in accounting for the oligarchs who run the mafia state). Ukraine is central to Putin’s ideology and subjectively important to Russian society, and the desire to obliterate and absorb the nation of Ukraine far predates the history of NATO (see also Adam Tooze’s excellent essay on understanding Russia as a strategic petrostate). As Hanania writes on his Substack (worthy of your subscription, by the way)4: We know what the Russians want. They have made clear, openly and consistently, that they do not want NATO to keep expanding. When it became apparent in December that an invasion was on the table, the US started a diplomatic process that has involved trying to work out concessions on other things, while refusing to take NATO membership for Ukraine off the table. Putin has become Satan in liberal imagination, and when it comes to the culture war, the emotional response is overwhelming. Hanania writes: Brexit, Trump, and the rise of Orban and other right-wing populists in Europe have helped solidify a narrative in which Russian hackers and influence operations are behind everything liberal elites find distasteful, from opposition to Syrian refugees to bans on Critical Race Theory. Here’s a website laying out all the things Russia has been accused of “weaponizing” in the media, including dolphins, federalism, and the weather. The details of debates surrounding the wisdom of NATO expansion and whether Ukraine actually matters to the United States are lost in the larger story, as emotional denunciations of Putin as the source of all anti-democratic activity drives attitudes and policies. Inconvenient facts are ignored because it’s not really about “democracy,” “international law,” or any of the other words they use to obscure the fact that it’s culture wars all the way down. And the Western response is driven by extreme public outcry to an unprecedented extent: It’s all a competition to see who can signal “I hate Putin” the most, but Germany was still shutting down all its nuclear power plants to rely on Russian gas despite warnings from every other EU state (Russia accounts for 40% of Europe’s gas imports) — so much for grand strategy. That is not to excuse Putin’s invasion (he is, after all, the aggressor) and no, Ukraine is not “the West’s fault” as Mearsheimer has claimed in his viral lecture, but “NATO’s door remains open” for me and “we're going to start WW3 because you're in my sphere of influence” for thee is no grand strategy at all. Indeed, the irrational Western response is not predictable by the unitary actor model, but by the public choice model. Hanania writes: If you were going to cut Russia off from SWIFT, for example, why wouldn’t you announce it beforehand? The whole point of a punishment like that is supposed to be its deterrent effect, but if you don’t communicate that a specific action will happen, then it can’t influence behaviour. The answer here seems to be a lack of grand strategy, with leaders responding to events according to emotion and public relations more than anything. Cutting off SWIFT, or even threatening to do so, seems extreme before an invasion occurs, but not after it has begun. The West cannot rely on sanctions to make Russia abandon its core national security interests, which at the very least include a no-NATO commitment, the acceptance of the secession of Donetsk and Luhansk, and the recognition of the annexation of Crimea. Sanctions will also push Putin closer to Beijing, and the US will continue down the self-defeating path of alienating both of the other two superpowers — so much for American grand strategy. Hanania writes: Even if Putin has maximalist aims at this point, that doesn’t mean sanctions are worth doing. Their costs are high and they may have major consequences for the global economy. One has to consider the possibility that they make Russia more repressive at home and more brutal in its persecution of the war. Putin is getting sanctioned, but ordinary Russians are getting cancelled. The Metropolitan Opera of New York has announced it will no longer stage performers who have supported Russian President Vladimir Putin. Carnegie Hall has done the same, and the Royal Opera House in London is cancelling a planned Bolshoi Ballet residency (one of the oldest and most prestigious ballet companies in the world). Eurovision banned Russia. Tchaikovsky is cancelled. As Tyler Cowen writes, cancel culture against Russians is the new McCarthyism. The culture war has morphed into a hyperreal form on the Internet. Just as COVID is the first pandemic in the Age of Twitter, so the Ukraine invasion is, in some sense, the first war in the Age of Twitter. As it unfolds, we are seeing many disturbing parallels to the events of early 2020. People are rapidly normalising once-fringe ideas like a NATO-enforced no-fly zone (while completely oblivious to the fact that it means shooting down Russian planes and causing WW3), direct US conflict with Russia, regime change in Moscow, and even, incredibly, the use of nuclear weapons. The overnight flips on German defence spending and SWIFT are like the overturning of conventional public health policies on masking and lockdowns. We have entered the age of shitpost diplomacy, as coined by Tanner Green, in which the official Twitter account of the US Embassy in Kiev literally posts memes to spite Putin: A Russian sixth-grader could explain why celebrating the glories of Kievan Rus does not subvert Putin’s claims about the history of the Russian nation so much as reinforce them. Just like Hong Kong’s protests, Ukraine has won the meme war with utterly lopsided propaganda and unanimous international support on the Internet. As Yoshimi writes: Floating ghostlike above it is our war, the myth of the ‘Ghost of Kyiv’, ace MIG-29 pilot who has apparently shot down six Russian planes, or the legend of the Ukrainian soldiers defending an island outpost who replied “Russian warship go fuck yourselves” to a surrender offer and may or may not have died heroically, or two Russian II-76 transport aircraft that maybe were shot down near Kiev, or videos of air strikes or dead bodies which variously are Russian or Ukrainian until they turn out to be from Gaza six years ago, or the viral video of an old Ukrainian woman telling off a Russian soldier by offering him sunflower seeds so when he dies, sunflowers (Ukraine’s national flowers) will sprout from the soil. We’re raising funds for the Ukrainian army on crowdfunding apps and giving advice to the civilians being handed assault weapons about how to disable tanks, sharing weird homophobic pictures of Putin as a gay icon and spamming Russian government posts. Ukrainian president Volodymyr Zelensky has made the decision to stay and fight rather than flee like most would-be leaders who go all in for American foreign policy, and now is being deified by us as “badass”, “a true leader”, etc. etc., alongside his people, whose resistance to authoritarianism we are told is unparalleled in the modern world. After all, so it goes, who could be next? And like in Hong Kong, despite winning the culture war in hyperreality, the actual war in reality is won by the side with overwhelming military might, not morality. The real war is where Ukrainians are experiencing the genuine life-shattering effects of military conflict. It matters because this is the first time Western response is driven by Twitter outcry, and it will not be the last. A New EA Cause? Besides Hanania’s recommendations in the last section (which he admits are more or less impossible in an excellent interview with Caplan), a worthy EA priority might be to somehow turn the public tide on sanctions, which literally kill more people than Putin. Americans should be appalled by the atrocity committed in their names. The banality of the incompetence of foreign policy elites does not excuse their evil. With how entrenched the special interests are, I have no idea if it’s even worth trying, but at the very least the sheer amount of suffering and death from sanctions should be made common knowledge. Nuclear security is one of the top priorities in Effective Altruism, per 80,000 Hours, Future of Life Institute, and Our World In Data. Toby Orb, who wrote the definitive book on existential risk, The Precipice, estimates x-risk from nuclear war to be ~1 in 1000 in the next century. Luisa Rodriguez estimates a 1.1% chance of nuclear war each year and that the chances of a US-Russia nuclear war may be in the ballpark of 0.38% per year; summarised by Max Roser as: Nuclear risk is neglected by the public because of Pax Americana since the collapse of the USSR, and is not discussed as often in EA as it’s thought to be relatively well-funded and mainstream, but in fact major donors like the MacArthur Foundation have been withdrawing funding. As Joan Rohling details in an 80,000 Hours podcast there is much to be done, especially when Ukraine gave up their nuclear arsenal in 1994 in exchange for Russia’s promise to never threaten or use military force against them. A worthwhile adjacent cause area might be de-escalation of public outcry to reduce x-risk from nuclear war beyond just regular anti-proliferation efforts — even a Russian specialist from the RAND Corporation is surprised by how much public outrage is driving policy: Even just the pace of the sanctions: we went to 11 out of 10 in like two days — farther than many expected we’d ever get in short order. And I think the same is true about these military assistance initiatives. We’re just trying to do something because there’s a public demand for action. So that’s what worries me, that the sort of public outrage that’s being channeled in Western democracies through political systems could result in decisions that prove ultimately unwise. Despite how odd it is that some wars are “legal” while others aren’t, we should be glad UNSC exists as much as everyone laughs at how useless the rest of the UN is. All is fair in love and war, but international norms is all that stands between us and nuclear annihilation. It is hard to emphasise just how delusional it is for the public to fixate on no-fly zones — I, like Scott, am surprised we’re still capable of jingoism. 80,000 Hours has updated their top career recommendations to include China specialist to improve China-Western coordination on global catastrophic risk, which seems more important after reading how irrational and captured the American foreign policy apparatus is. As Hanania writes, “great power competition” is an anachronism. If Ukraine is the first war warped by hyperreality, it won’t be the last. Now that US foreign policy elites have driven Putin into the arms of China, let’s hope IR specialists can imbibe the public choice model instead of antagonising yet another nuclear rival. Public Choice Theory and the Illusion of Grand Strategy is an important work because it raises the sanity waterline, which at the least should make us stop killing millions for no reason, and at the most should make the human race more knowledgeable of how to prevent total extinction from nuclear armageddon. Pax Americana is dead, but a multipolar world will be more humane. Endnotes In the fiscal year 2018, the top five government contractors were all weapons manufacturers, with Lockheed Martin in first place at $40.6 billion. The Department of Defence spent $358 billion on contracting, ten times higher than second place Department of Energy. Collective action problems that stop a bunch of smaller companies from effectively influencing policy are no hindrance for companies like Lockheed Martin.

The Question Of Separatism
May 19, 2023 · Original source
… and we think, thank goodness that Germany is unified now. So much easier to think about! Can you imagine if the Our World in Data charts had to show separate lines for the Electorate of Saxony, the Prince-Bishopric of Augsburg, the Duchy of Brunswick-Lüneburg, and about 1,800 other semi-sovereign states? Can you imagine traveling around if each of them had its own currency? (Fun fact: the List of states in the Holy Roman Empire Wikipedia page doesn’t contain such a list. Instead it points to no less than 28 sub-lists.) Jacobs stops shy of asking, in either book, the question that seems to be the logical continuation of her reasoning: should everything be a city-state? Should we encourage separatism until each inhabited place in the world is either a city or a city region with its own currency? We can hazard a guess as to what her answer would be. She would probably say that there’s no need to upend everything right this moment. Just adopt an attitude of political openness and experimentation. Don’t try to hold together entities that don’t work that well. When separatist sentiment arises somewhere, you can argue it’s a bad idea, but don’t fight it out of emotion such as fear for your nation’s integrity. Eventually, things will settle — the regions that want to be city-states will be, and those that prefer to be united with others, for cultural or economic reasons, will stay that way. Unity has good PR and some genuine advantages, so there will still be plenty of it. But maybe Jane Jacobs never asks this question because she knows it’s irrelevant. We just can’t help fighting for our big countries and supranational unions (like the EU), and too bad if they enter long periods of stagflation until they violently collapse. This might be the right time to mention that her last book, published in 2004, is called Dark Age Ahead. IV. Something to Dislike For Everyone Jane Jacobs’s most famous book is The Death and Life of Great American Cities. She is recognized as perhaps the most influential thinker in urbanism. She is credited with saving Greenwich Village and SoHo in New York City, and helping cancel the Spadina Expressway in Toronto. To this day people organize “Jane’s Walks” as a living memorial to her impact on cities. But Jane Jacobs herself thought that her greatest intellectual contribution was not in city planning, but in economics. She thought that import replacement was her most important discovery, since it explained how wealth expands better than existing macroeconomic theories. She wrote multiple books that were explicitly about economics and was about to write another when she died, Uncovering the Economy. I am not an economist, so I might not be qualified to make a judgment on this matter, but: it seems to me that there’s a discrepancy here. Jacobs is widely seen as a great intellectual, but her economic ideas don’t quite seem mainstream. I’d never heard of import replacement before reading her book. Why not? The null hypothesis is that economists have examined her ideas and simply rejected them. There were some critical academic reviews of Cities and the Wealth of Nations when it came out, and more recently Tyler Cowen expressed his own mild skepticism. Some of the criticism involves the lack of quantitative data in her work, and her failure to think about issues of scale. The most obvious target, of course, is her city obsession: yes, cities are important, but they’re not the only economic phenomenon that matters, some would say. Perhaps Jacobs has overplayed her hand. But there are other possible explanations for the discrepancy. One is that she was a woman and had no credentials, which made it difficult for (mostly male) professionals to take her seriously. We know this was true at the beginning of her career at least. It seems possible that even after she managed to establish herself as an original urban thinker, economists had trouble accepting that she could, with her lack of any college degree, come up with new insights in their field. I doubt that’s really true today, though. We do take Jacobs seriously, and still read all of her books, which is more than we could say about most economists. Instead, I propose that the discrepancy comes from a darker place: in laboring to be comprehensive about cities and economics, she reached conclusions that most people don’t want to be true. No matter your politics, there’ll be something for you to dislike in Jacobs’s work. For example, it’s pretty clear that she didn’t think the European Union was a good idea, so she probably would have supported Brexit. Brexiters might rejoice, except that a lot of them are British nationalists who certainly don’t want Scotland to leave the UK, whereas Jacobs would agree with that. Which would be great news to Scottish independentists — except that if a new separatist movement arose within Scotland, she’d also support that. Jacobs’s ideas and grassroots activism in favor of small-scale, organic urban planning have come to be seen as left-wing — yet her criticism of national welfare programs wouldn’t make her out of place among hardcore right-wingers. Unless those right-wingers were military hawks, in which case they’d find no solace in reading Jacobs on military transactions of decline. Writing during the Cold War, Jacobs criticized the Soviet Union for its incredible centralization of decision-making in Moscow. She rightfully predicted its collapse, making her an ideological ally of the capitalist West, right? Not so, since the United States is also, according to her, too centralized and in the early stages of decay. “Today the Soviet Union and the United States each predicts and anticipates the economic decline of the other,” she writes. “Neither will be disappointed.” Whether she was correct about the US is left as an exercise to the reader. In any case, she did foresee, using her theory on cities, the decline of Japan. This must have been bold in the 1980s at the peak of the Japanese economic miracle, when there was a widespread trope that Japan would soon take over the world. Yet she was right: in 1991, Japan entered its “lost decade,” which soon became two lost decades, and then three. To be fair, she predicted the decline of all large-ish countries, so I wouldn’t mark her as a superforecaster or anything. Still, this puts in perspective the more recent trope that China is going to take over the world. No country, no ideology is safe from Jacobs’s prophecies. Smaller ideologies aren’t spared, either. Effective altruism would probably seem totally mistaken to her, since at its core it promotes an inorganic, top-down transfer of wealth from prosperous cities to poor areas. Progress studies people think that technological innovation will solve economic stagnation, but she would point out how labor-saving equipment so often causes damage when it is introduced to regions that don’t benefit from the other city forces, like the Scottish Highlands or many of her other examples in Colombia, India, or the American South. (This point would deserve an essay of its own, but reading Jacobs has made me a bit more worried about the “AI will take our jobs” thing. It’s clear that new jobs will appear, but when the technology city force from the San Francisco Bay Area reaches distant places with poor economies, which it will very soon thanks to the internet, the effects might not be very pleasant to see.) Overall, the political ideology that might fit Jacobs the best might be… libertarianism? She’s not a big fan of large governments who make big top-down decisions, clearly. Yet I don’t get the feeling that this association fits all that well either. Jacobs doesn’t seem to be anti-government if the government is at the city level. I doubt she would have liked the kind of hyperfragmented world depicted in Snow Crash by Neal Stephenson. I also doubt she’d be impressed by cryptocurrency-backed “cloud cities” or fantasies of charter cities, none of which she would see as real cities in the sense of concentrated pockets of people who start replacing what they import with local production. Jane Jacobs, in sum, was an archetypal accidental moderate. She took one idea very seriously — the idea that cities are fundamental — and explored its ramifications without caring in the slightest if it led to the “wrong” opinions, as her friends in 1980 Toronto must have thought when she wrote about Quebec. I don’t know if she went too far; I’m sure someone more qualified than I am can find flaws in that core idea or any of her other observations. But to me she sounds convincing, and her consistency is frankly admirable. So, to end this review on a more review-y note, go read Jane Jacobs. Her books are a delight, with their elegant arguments and masterfully told anecdotes. Her predictions often take an air of doom, but she is also an optimist who offers constructive ways forward. She sets an example for all of us who care about getting the details right, no matter the credentialed experts, the current political climate, or the great theories of the past.

Highlights From The Comments On British Economic Decline
July 20, 2023 · Original source

A World Bank graph requires a little more interpretation, but goes up to 2022: Source: World Bank. Britain is the thick blue line. …and it also shows UK growth being about average. So what’s going on? I asked about this in an Open Thread. Here were some of your responses. Eric Rall writes: There are two different ways of calculating real GDP per capita in an international context, both of which involve converting local currency to dollars and then inflation-adjusting the dollars based on the US's GDP deflator. One uses market exchange rates, while the other uses "Purchasing Power Parity", attempting to optimize the GDP figure as a proxy for standard-of-living by using local prices for equivalent goods and services as the currency conversion factor. For Brexit-related and COVID-related reasons, the relationship between PPP and market exchange rates for Britain have been highly unstable in the period in question: exchange rates have been very volatile (ranging from US$1.08 to US$1.40 per £1.00), and tariffs and COVID disruption have both radically changed the availability and prices of imported goods. Looking at either the PPP or market exchange rate numbers, everyone took a big hit in 2020, while Britain appears to have taken a deeper hit than France and the overall OECD average (the two control groups I picked off the top of my head). The big difference is that in market exchange rate terms, the recovery looks proportionate to the decline (i.e. Britain fell more, but also recovered proportionately faster so as to bounce back to approximately 2019 levels in 2022 the same as France and OECD): (source) But in PPP terms, the UK has recovered at the same rate as France and OECD and thus appears to have permanently (so far) lost ground in standard of living relative to other countries.

Is this because Britain had a worse COVID experience than other countries, or because they were having a normal COVID experience plus effects from Brexit?

Each of these has their own local story. In Britain, it’s the paradoxical effects of Brexit. In the US, it’s Joe Biden being soft on immigration. And so on - but should we be looking for some deeper cause that explains the overall phenomenon? A commenter suggests “a way to soak up all the inflation from the COVID money printing”, but I can’t tell if that even makes sense. Still, should something something COVID be a leading hypothesis? 27: Jesse Singal vs. Mark Stern on the Skrmetti Supreme Court case that failed to overturn Tennessee’s ban on gender medicine. US law bans sex discrimination, so pro-transgender advocates argued that, since doctors often prescribe eg estrogen to biological women, it was sex discrimination to ban prescribing it to biological men. Tennessee’s anti-transgender argument was that they weren’t discriminating by sex, they were discriminating by diagnosis (estrogen for eg hot flashes, vs. estrogen for gender transition). There is some subtlety here (if a biological man grows breasts because of some hormone imbalance, doctors might give him testosterone to counteract it, and this seems sort of like giving biological women testosterone to make them look less like women), but these are still sort of different diagnoses (gynecomastia vs. gender dysphoria) and Tennessee said you can still think of it as diagnostic discrimination rather than sex discrimination. This makes sense, except that the standards around sex discrimination are very strict and sort of box the court in here. And in a fit of wokeness, the 2020 court (including some of the conservative justices hearing this case) applied these standards very strictly and ruled that discriminating against gays was a form of sex discrimination (since if women can date men, it’s sex discrimination if men can’t also date men), and this is obviously the same argument. Now that wokeness is less popular, the court wants to rule against transgender, but it can’t help tripping over its previous ruling and giving some kind of unprincipled confusing non-opinion. 28: Contra compelling anecdotes, only ~5% of people raised very religious end up atheist later in life (X). Most people are about as religious as their parents; most exceptions are only slightly less religious, and most families that secularize do it over several generations. Note: percentages are of total, not of each row! 29: Related: social science team proposes a three-stage model of secularization: decreased public ritual participation → decreased personal importance → decreased identification, presents apparently confirmatory data. If true, would be somewhat inconsistent with intellectual models (eg people learn about evolution and start doubting the Bible) and more consistent with institutional models (eg the government provides welfare so people no longer need to be part of a tight-knit church). 30: Navigating LLMs’ spiky intelligence profile is a constant source of delight; in any given area, it seems like almost a random draw whether they will be completely transformative or totally useless. Now Ethan Strauss reports that they are, for some reason, extraordinarily effective at teaching people golf. “I am predicting the Golf Revolution, or perhaps decline, if your perspective is that optimization tends to ruin hobbies. A sport for obsessives has been gifted the ideal tool for refinement.” 31: Claim (via nxthompson on X): “In a huge survey of young kids about phones and technology, they all say they want to be out playing in the real world. But parents don't let them out unsupervised. So they're stuck on their phones.” Interesting, but I’m nervous about social desirability bias - how many adults would say on a survey that they would rather be on their phones than playing with friends? But adults do have this choice and mostly go with the phones. 32: Steven Adler on AI psychosis. He tries to analyze ER admissions data for psychosis and finds no change. I don’t think anyone reasonable expected this to be a large enough effect to show up in ER admissions data, but there are lots of unreasonable people so I appreciate his effort. He thinks AI companies might have better data on this, and encourages them to release it. 33: Cuartetera was the greatest polo horse ever. Polo players responded in a very practical way: they cloned her, dozens of times (and it worked; the clones are also excellent). Now there is a lawsuit as different polo teams fight to get their hands on Cuartetera clones. What is the equilibrium? If the outsiders get their hands on the genetic material, do we see a world where every polo horse is a Cuartetera clone? How much is lost if nobody ever tries to breed a polo horse better than Cuartetera (since the economics might not check out if the odds of success for any given foal is too low)? H/T Gwern and Siberian Fox (on X). 34: Claim: as of 2013, India’s Agarwal caste, who make up less than 1% of the population, got 40% of the e-commerce funding. 35: Owlposting: What Happened To Pathology AI Companies? Pathology is a medical specialty. A typical task involves looking at a microscope slide full of cells and trying to determine if any of them are cancerous. This seems like a good match for AI - and for years, studies have been showing that in fact AI can equal human experts. So why isn’t it being used more? The author’s three answers: first, slide scanning is expensive and clunky, and you can’t apply AI to a slide until you digitize it. Second, it’s hard to figure out a business plan where this saves someone money and doesn’t step on the toes of big companies that can outcompete anyone they don’t like. Third, pathologists use the context of a patient’s entire clinical history when they interpret a slide, and AIs that can’t do that (either because of technical limitations or legal/privacy limitations) are at a disadvantage even if their skills specifically relating to slide-reading are better. 36: Noahpinion: Will Data Centers Crash The Economy? Suppose that AI is a bubble, either permanently (because the technology isn’t really transformative) or temporarily (because it can’t transform things quickly enough to keep up with all the dumb money pouring into it). Will the sudden write-off of data centers lead to a broader economic collapse? In 2001, the dot-com bubble harmed the tech sector, but didn’t take the rest of the economy down with it; in 2008, the subprime mortgage bubble did take the rest of the economy down with it, because it damaged banks that the whole economy relied on. The optimistic case for AI is that data center spending is mostly coming from big companies like Google and Meta that can absorb a lot of loss. The pessimistic case is that some of the money is coming from private credit, a new-ish form of finance which hasn’t really been stress-tested and whose failure modes are still poorly understood. Noah’s final verdict: the stage isn’t obviously set for a crisis yet, but there’s the potential to get there and we should consider acting (how?) early. 37: The latest Twitter talking point is that universal hepatitis B vaccination at birth is “woke”: Hep B is (aside from mother-to-child transmission) often sexually transmitted, slutty women’s children are more likely to have Hep B, so perhaps giving the vaccine to everyone (instead of testing and only giving to the children of women who test positive) is an attempt to spare slutty women the embarrassment of getting a positive test. Ruxandra Teslo provides the counterargument - Hep B tests take a while, the medical system is fragmented, and any attempt to test people and then give the vaccine inevitably leads to many positive tests falling through the cracks. Vaccinating at birth is easy and hard to screw up, the vaccine has no known side effects, and empirically child Hepatitis B rates go down (by as much as 2/3!) when countries switch from test-and-vaccinate to universal vaccination. This benefits everyone - even people who never have unprotected sex and always follow up on their medical tests - because toddlers in daycare exchange saliva copiously, and if your toddler exchanges saliva with a Hep B positive toddler they could get the disease. A funny Twitter interaction was seeing Republicans in Congress hop on the anti-slut anti-vaccination bandwagon - except for Senator Bill Cassidy (R-Louisiana), who happens to be a liver doctor, and who is still fighting the good fight. I am always nervous when a good person who I like starts engaging on Twitter, since it elevates the discourse there but also gradually turns their brain into mush - but Ruxandra has made the leap and is doing a great job not just on bio related topics but also (for example) countering Curtis Yarvin on the history of her native Romania. 38: The response to GPT-5 was confusing; most specific people who reviewed it said they were impressed (Ethan Mollick, Tyler Cowen, Nabeel Qureshi, Taelin), it performed as expected on formal benchmarks, but the overall vibes declared it a big failure. Peter Wildeford speculated that maybe there was some kind of sinister pay-to-play early access bias involved. Zvi went the other way, calling it a “reverse DeepSeek moment” (insofar as DeepSeek was a pretty average model that got glowing praise.) In the end, I agree with Peter that this was mostly a branding issue. o3 was a genuinely revolutionary model; if OpenAI had called it “GPT-5”, it would have met expectations. Instead, they called it “o3”, and called a minor incremental update a few months later “GPT-5”. Then people got mad that the exciting-sounding “GPT-5” was merely an incremental update. A secondary issue was that the router wasn’t very good, and so many queries got routed to a small version without thinking mode that was if anything a downgrade from o3. I think this tweet by Shakeel perfectly encapsulates the essence of GPT discourse in two sentences: …but maybe it’s worth asking why GPT-5 isn’t bigger than o3. Was 4.5 a failed attempt at scaling? Did it fail in a way that sort of back-handedly justifies the “lost steam” take? Does the answer depend on distinctions between pre-training scaling, post-training scaling, etc? How? 39: This month in etymology: did you know that “oy vey” is a “fully Germanic phrase” which is cognate with English “oh woe!” (h/t Wylfcen on X) 40: mRNA shows promise to be a game-changing treatment for cancer, but RFK is trying to halt research. But so far he can only starve it of money, not ban it, and the funding gap is only $500 million. Will there be enough philanthropic billionaires and private foundations to step up? Zvi points out that although there is usually a game of chicken where foundations are hesitant to touch something the government cancelled lest the government decide it can cancel everything and hope philanthropists pick up the bill, in this case there are no game theory considerations - RFK is halting it because he genuinely wants it halted, and they are thwarting him rather than playing into his hands. The only problem is that $500M is a lot of money for the private sector; a few foundations could technically afford it, but not many could afford it comfortably and still have money left over for the next few crises of this magnitude. I hope someone is trying to organize a coalition. 41: AI fantasy flash fiction Turing test. Eight stories about demons, four by famous fantasy authors, four by ChatGPT. After 3000 votes, AI wins: humans can't tell the difference and slightly prefer the AI stories. My own score was only 75%. But I will say that I thought Mark Lawrence's was obviously the best, I was ~100% sure it was human, and it convinced me that regardless of the official results it's still possible to write flash fiction that an AI obviously can't do. 42: “SignPro” offers customized “In This House We Believe” signs, try not to use this for evil. 43: China think tank assessment of how in control Xi is: still very in control, maybe not infinitely in control. 44: Related - did you know (h/t xlr8harder) that if you ask AI to write a science fiction story, it will very often name the protagonist “Elara Voss” (or some very close variant like Elena Voss), and this remains true across various models and versions? Related: Chelsea Voss of OpenAI is having a baby and has the opportunity to do the funniest thing. 45: “Hector (cloud) is a cumulonimbus thundercloud cluster that forms regularly nearly every afternoon on the Tiwi Islands in the Northern Territory of Australia…[he is sometimes called] Hector the Convector”. 46: British allergy sufferers who want to know the ingredients of things demand that British cosmetics stop listing their ingredients in Latin. “For example, sweet almond oil is Prunus Amygdalus Dulcis, peanut oil is Arachis Hypogaea, and wheat germ extract is Triticum Vulgare.” 47: Text-based RPG about being an NYT journalist at the Manifest prediction market conference. I make a brief appearance. 48: Study uses supposedly-random variation in doctor assignments to test whether the marginal mental health commitment is good or bad for patients, finds that it is quite bad. Freddie de Boer is violently skeptical (maybe literally so?) and makes some good points about how a single quasi-experimental study is never absolute proof. But I don’t think he quite justifies his opinion that the paper was irresponsible and should never have been published; it’s just a normal quasi-experimental study that we should nod and say “huh” at but not overweight as the culmination of all possible research that overcomes all possible priors. My prior is that the marginal commitment is pretty useless (many commitments are just “well, since this person arrived at our ED for some reason, it would look bad from a medico-legal perspective to just let them go, so let’s keep them a few days to evaluate” - and yeah, you should be upset about this) but I’m still surprised by how many outright negative (as opposed to zero) effects the researchers found. The strongest argument for negative effects is that it will make some people miss work and maybe lose their job. But this study found that commitment ~doubles the risk of near-term suicide (admittedly only from 1% to 2%), which would have been outside my confidence intervals for how bad it could be. I suspect confounding, but only on general principle, and I wouldn’t be too surprised either way. 49: This tweet is probably bait, but I found it a thought-provoking question: I think there’s a boring answer, where the law is more complex than just a single number and whatever kind of weird trafficking Epstein was doing is worse than whatever normal relationships these European laws are permitting. But assuming that there’s a substantive difference even after taking that into account, I think my answer is something like - we’ve got to divide kids from adults at some age, there’s a range of reasonable possible ages, we shouldn’t be too mad at other societies that choose different dividing lines within that range - but having decided upon the age, we’ve got to stick with it and take it seriously (in the sense of penalizing/shaming people who break it). This is more culturally relativist than I expected to find myself being, so good job to Richard for highlighting the apparent paradox. 50: Dilan Esper describes his experience as one of Hulk Hogan’s attorneys in the Gawker lawsuit (X). Parts I found interesting: none of the lawyers knew Thiel was funding the lawsuit; Gawker probably could have won if they had been slightly competent but kept "shooting themselves in the foot"; and Gawker probably could have won if they had just pixelated the private parts in the video. 51: Amazing concept and poems (link on X): I tried to see if AI could do this, and it did something that technically met the requirements but had zero artistic merit - using a lot of words like “nowhere” and “outside” in one, then separating them out to “no where” and “out side” in the other. I didn’t invest much energy in creating a clever prompt telling it not to do that, so feel free to report if you get better success. 52: New study claims consultants are actually good, at least for profits: "We find positive effects on labor productivity of 3.6% over five years, driven by modest employment reductions alongside stable or growing revenue" 53: A Polish team tries to test Peter Turchin’s equations for predicting political unrest on recent Polish history, has to make some changes but claims mostly positive results. 54: New big multi-author Substack, The Argument, trying to be a sort of center-left version of the model pioneered by The Free Press and other high-production-value ideological Substack properties. Excited to see Kelsey Piper is involved, and she starts off strong with a post on the latest round of First World basic income studies, which find few positive effects. This is surprising, because recipients didn’t waste the money on alcohol or gambling or anything - they paid down debt and got useful goods. Still, it didn’t even affect things that should have been obvious, like stress level. It’s not even clear that amounts of money large enough to help with rent made homeless people more likely to get houses! Matt Bruenig criticizes the article, accusing Kelsey’s studies of being downstream of Perry Preschool style dreams that exactly the right welfare program will have massively compounding effects that cut poverty out at the root and turn everyone into elite human capital; he thinks giving people money won’t do this, but it will increase equality and give the poor better lives. I assume he’s not a strong hereditarian, but his argument makes even more sense from that perspective, and I’ve certainly criticized dumb outcome measures like infant brain waves which we have only tenuous reasons to think are related to anything we care about. But Kelsey reasonably responds that the outcome measures she’s talking about include stress level and life satisfaction. To defuse this critique, Bruenig either has to argue that our construct “life satisfaction” doesn’t really measure whether someone’s life is satisfactory, or else claim that giving poor people satisfactory lives isn’t really what we’re going for - which I think would require more explanation on his part. There’s some further (impressively acrimonious) debate on X, but I don’t see anything that addresses my core concern. GiveDirectly, a charity involved in basic income experiments, has a presponse here; they say that some studies are positive, and that the ones that aren’t might have tried too little cash to matter, or been confounded by COVID making everything worse. They also point out that basic income is harder to study than traditional programs like giving people housing, because if you’re giving housing you can measure housing-related outcomes directly and have a pretty good chance of getting enough statistical power to find them, but since everyone spends cash on different things, the positive effects might be scattered across many different outcomes (and therefore too small to reach significance on each). Everyone involved in this debate wants to emphasize that the poor results are for First World studies only, and that studies continue to show large benefits to giving cash in the developing world. 55: Related: I was less impressed by The Argument’s first foray into housing policy, which follows an all-too-familiar pattern: Some people say they don’t like noise and disorder and try to make rules against it in their apartments.
