Book Review: The Cult Of Smart

February 18, 2021 · Original source

The Cult Of Smart invites comparisons with Bryan Caplan's The Case Against Education. Both use largely the same studies to argue that education doesn't do as much as we thought. Caplan very reasonably thinks maybe that means we should have less education. DeBoer...definitely doesn't think that:

Toward A Bayesian Theory Of Willpower

March 26, 2021 · Original source

I think the most immediate gain to having a coherent theory of willpower is to be able to more effectively rebut positions that assume willpower doesn't exist, like Bryan Caplan's theory of mental illness. If I'm right, lack of willpower should be thought of as an imbalance between two brain regions that decreases the rate at which intellectual evidence produces action. This isn't a trivial problem to fix!

Long COVID: Much More Than You Wanted To Know

September 02, 2021 · Original source

This is terrible. Recovery rates in the single digit percentages over the space of years. You would think at least some patients would get placebo recoveries, or forget how it felt to be well, or otherwise Lizardman themselves into fake complacency, but no. This is f@#$ing awful. Maybe COVID won’t be this bad? One ray of hope comes from this Australian study, where doctors record the rates of recovery from postviral fatigue after various rare diseases they encounter (Epstein-Barr, Q fever, Ross River virus). They find that 35% of these patients have postviral fatigue after six weeks, but only 12% after six months, and 9% after twelve months. This sounds a lot better than chronic fatigue. In fact, these people do the kind of weird task of figuring out how bad different diagnostic labels for fatigue are, even though some might argue that all the labels refer to the same underlying reality. They find an official diagnosis of “CFS/ME” (chronic fatigue / myalgic encephalitis) is much worse than “postviral fatigue”. Using the weird measure of “days per year of followup with diagnosis” (I’m not sure I fully understand their reasoning for why this is good), they find a median length of 80 for CFS/ME vs. 0 for PVF (…huh?). Using the more comprehensible measure of percent who still complain of fatigue after 7-12 months, they find it’s 24% vs. 10% (which super contradicts the above study saying that basically nobody with a CFS/ME diagnosis ever recovers). My guess is that this study had much lower criteria for a CFS/ME diagnosis (some doctor diagnosed it and put it on the insurance records) compared to the ones above (some specialist confirmed it by official criteria). The conclusion I draw is that, while official CFS/ME is horrible and hopeless, there are a lot of things that unofficially look kind of chronic-fatigue-ish which have pretty good prognoses. Since there’s no good reason to think post-COVID fatigue is official CFS/ME as opposed to just some chronic-ish fatigue-ish thing, probably it will have a better prognosis, more like weird Australian viruses. …which we still don’t know, because AFAICT nobody has done any good studies on postviral fatigue lasting more than a year. 5. Psychosomatic symptoms probably aren’t the majority of long COVID. I mean, I’m not seeing too many people claiming that they are. There are a lot more people worried that someone else might be claiming that, than people actually making the claim. Still, the Wall Street Journal opinion section is always up for slathering itself in glue and rolling around in a haystack until it becomes the straw man everyone else warned you about, and they do have an article on The Dubious Origins Of Long COVID. They point out that long COVID was first thrust into the public consciousness in surveys run by Body Politic, who self-describe as “a queer feminist wellness collective merging the personal and the political”. I agree this is a weird source for something to come from, but Hans Asperger was a Nazi and I still use his diagnosis, so I probably have to accept these people’s as well. More relevantly, WSJ points out that many of the people complaining of Long COVID symptoms test negative for COVID, or at least never tested positive. This complaint conflates the fact that not everyone was able to get a COVID test at all, with the fact that sometimes you get the acute COVID test after you’ve recovered from acute COVID and it’s negative, with the fact that COVID tests don’t have a 100% success rate, with the fact that yeah, okay, some people who didn’t have COVID are probably imagining Long COVID symptoms. I feel like some of the case-control studies above, which clearly show that seropositive people have higher rates of Long COVID than seronegative people, are pretty convincing here. But also - the people with lung scarring clearly have lung scarring, and most of them have weird x-rays consistent with lung scarring. If you have lung scarring, then you have trouble breathing, you’re fatigued, and you probably have lots of other stuff downstream of that. The people with smell/taste disturbances clearly have smell/taste disturbances, testable with the stupidly named but scientifically venerable Sniffin Sticks test - and also, who even cares enough to make up olfactory problems? Fatigue and brain fog are the only symptoms here that can’t be easily objectively confirmed, and, well, do you think those Australians who got infected with Q fever and had twelve months of postviral fatigue are faking? What about all those post-Epstein Barr fatigue people? Lots of viruses cause postviral fatigue, it’s not really surprising that COVID should also. (WSJ also spends a while arguing that CFS/ME is just a psychiatric disorder, which I think is not really in keeping with the best recent evidence. Also, as a psychiatrist, I’m very against this conclusion, mostly because if it were true, then people would expect me to cure CFS/ME patients.) One point WSJ didn’t bring up but could have was that most Long COVID patients are women. Probably this is somewhere between 60 and 80% - I suspect on the lower end of this, because I think women are more likely to talk about these kinds of things than men, and much more likely to eg join Facebook groups. This is noteworthy, because women are traditionally more prone to psychosomatic illnesses - so much that the ancients attributed these to the uterus and called them hysteria (note shared root with eg “hysterectomy”). Women are about 2x as likely to get diagnosed with panic disorder, anxiety disorders, phobias, etc, about 2.5x as likely to get chronic Lyme disease, widely regarded as an entirely psychosomatic condition, and 3-5x more likely to be diagnosed with fibromyalgia. So the female preponderance is suspicious. But women are also somewhere between 2x and 4x more likely to get autoimmune disorders than men (it varies by disorder - the ratio for Sjogren’s is as high as 16x). There are some pretty crazy hypotheses for why this is - for example, maybe women’s immune systems are permanently upregulated to be prepared for attempts by the placenta to secrete immune-downregulating chemicals during pregnancy, as part of the creepy shadow war between mother and fetus to regulate the maternal environment. I don’t know, do you have a better idea? Anyway, women have more autoimmune issues and more upregulated immune systems, so if there was any good way to assess gender ratio in true postviral fatigue excluding all psychosomatic cases, that would probably be female-biased too. Probably some Long COVID cases are psychosomatic just like some cases of anything are psychosomatic, but I don’t see too many signs that this is too important in explaining the phenomenon. …and please allow me a moment of preachiness here. Chronic fatigue sounds really fake to anyone who doesn’t have it. I think this is because it’s related to willpower. Willpower itself would sound fake to anyone who didn’t have to worry about it. “Oh, so you can go partying with your friends whenever you want, but as soon as it comes time to write a ten page report, your ‘lack of willpower’ prevents you from doing it? A likely story!” Still, all of us (except Bryan Caplan) recognize how real and important willpower is - how having more of it is better than having less of it, and how some condition that caused you to have pathologically little of it would be a huge disaster. In the comments section to the rough draft of this post, CJ wrote: I will say - I was one of those types of men to scoff with skepticism at people claiming to have chronic fatigue and the like. I would have called those people lazy and would have been adamant they were faking it or feeling like crap because of unhealthy lifestyle choices. Unfortunately I have learned the hard way the severity of neurological conditions, what it feels like to have brain fog, what chronic fatigue feels like, and how difficult it can be to communicate neurological symptoms to others. I now start from a position of listening to people who are willing to open up about their symptoms and trust that they are being honest. There are millions of people suffering in silence with untreated and undiagnosed disorders - those people are not all faking it or just dealing with psychosomatic conditions. I would recommend Jennifer Brea's documentary, Unrest. Thank you for shedding some light on the subject. Heron added: I second the suggestion to watch 'Unrest,' and to consider the many unseen ill whose symptoms are deemed to be imagined. Until this last year, I had little patience with, and doubted, people who I saw as hypochondriacs. Then I became the thing I hated. Myalgic Encephalomyelitis/Chronic Fatigue Syndrome and Long COVID do have similarities from what I've read, since becoming ill in August 2020. At that time, here in Northern Ireland, there was scant availability of COVID tests; after spending three days trying to get hold of one, (by which time I'd stopped teaching my post-grad online classes & I haven't worked since) I became too ill to do anything. I figured if this was COVID I'd gotten off lightly, mostly constant severe headache, inability to think, a new experience of fatigue, high temperature, insomnia, hypersomnia, paresthesia, no smell or taste etc Debilitated but not dead. Except for the fact that I still have the aforementioned symptoms a year on and whilst they fluctuate in type and severity, the fatigue, headaches and cognitive difficulties are real. A brain scan, an appointment for brain and spinal MRIs (waiting lists, even when going private [as NHS has 3-8 yr waiting lists here in NI] are lengthy), rare virtual doctors and neurologists suggest my ailments constitute a post-viral thing, maybe Long C, they can offer nothing but pills for pain. There is no test for ME/CFS yet, nor a Long C test, symptoms and presentation are so varied. Given a widespread lack of knowledge and resources regarding these ailments, you're on your own. Maybe I've developed ME, I certainly have post-exertional malaise which my very prominent neurologist hadn't heard of. Looking at the history of ME/CFS* and a dearth of research surrounding it, I hope that rather than dismiss the lives of sufferers of this or the long-lasting aftermath of COVID, that those experiencing such difficulties will be heard and learnt from. I only understood when I had no alternative. I don’t think I ever actively pooh-poohed CFS, but like everyone else who encountered it, I underestimated just how bad it was until I met some patients with the condition. It is real and really bad. For whatever reason it is hard to think about and take seriously, but it really is as bad as people say. </preachiness> 6. Long COVID is probably rare in children This matters a lot, because children are (currently) ineligible for the vaccine, and also likely to encounter the virus at school. But children usually have mild cases of COVID and don’t die from it, so it’s tempting to just not worry about them. But if they could get Long COVID, that would make it much less tempting. Preliminary Evidence On Long COVID In Children sounds like a good paper to draw conclusions from. It says 42.6% of children with COVID experience long-term follow-up symptoms, which would be higher than the rate for adults. But it has no control group, and most of the symptoms it finds don’t seem very COVID-related (eg rashes, constipation). The most common symptom (20%) is insomnia, which better studies in adults fail to associate with real Long COVID. The rate of known long COVID symptoms (eg taste and smell problems) is only about 3-4%, and no higher or lower than anything else. Probably these kids are just having problems at the usual rate and attributing them to their recent COVID. Blankenburg et al do the correct thing and ask a thousand children about potential symptoms, then compare the number who say yes vs. no among COVID-seropositive and seronegative subjects. They find no difference between the two groups. Both are reporting a lot of insomnia, etc. They reasonably attribute this to pandemics being a stressful event that it’s natural to lose sleep over. This is really reassuring, but it can’t rule out a somewhat rarer syndrome. The authors say that they might miss symptoms with a prevalence of less than 10%, and one of them gives his own personal guess that it’s 1%. An English team says there’s a Long COVID rate of 4.6% in kids. But there was a 1.7% rate of similar symptoms in the control group of kids who didn’t have COVID, so I think it would be fair to subtract that and end up with 2.9%. And even though the study started with 5000 children, so few of them got COVID, and so few of those got long COVID, that the 2.9% turns out to be about five kids. I don’t really want to update too much based on five kids, especially given the risk of recall bias (ie you might notice / care about your symptoms more if you know you had COVID before getting them). My overall conclusion here is that long COVID is rarer in children than adults, and may not exist at all. The studies tell us it’s probably somewhere less than 5% of kids, but so far we can’t conclude anything stronger than that. 7. Vaccination probably doesn’t change the per-symptomatic-case risk of Long COVID much Here’s a complicated Twitter thread about this. Of vaccinated people who got symptomatic COVID, about a third ended up with Long COVID symptoms, the same rate as in unvaccinated people. Of course, vaccinated people are much less likely to get symptomatic COVID. But even conditional on getting it, they’re still much less likely to go to the hospital, die, etc. It would have been nice if the same was true of getting Long COVID. But it doesn’t look that way. (all this information is from an online poll by a sketchy group of COVID “survivor” activists. But they wrote up their poll in the scientific paper font, as a PDF and everything, so I say we count it anyway) This NEJM study wasn’t exactly designed to look for Long COVID in vaccinated people. But they found it anyway, at a rate of 19% after 6 weeks. This also fits within the (wide) range reported for unvaccinated people. They don’t give a symptom breakdown beyond “prolonged loss of smell, persistent cough, fatigue, weakness, dyspnea, or myalgia”, which sounds like the usual set. These studies are pretty weak, and you could argue that given that vaccines decrease the average severity of COVID infection, and infection severity is linked to Long COVID risk, we should have a strong prior on vaccines decreasing Long COVID risk. And just before publishing this, someone sent me this study, which very preliminarily finds vaccines might decrease Long COVID risk by a factor of 2. I think a factor of 2-3 is believable; one of 10 or 20, less so. Weirdly, there are some claims that vaccines can help relieve symptoms of existing long COVID. Sounds kind of like sympathetic magic to me, but the researcher quoted in the linked article said it might “improve symptoms by eliminating any virus or viral remnants left in the body” or by “rebalancing the immune system”. So yeah, sympathetic magic. 8. Your risk of a terrible long COVID outcome conditional on COVID is probably between a few tenths of a percent and a few percent. My original calculation went like this: About 25% of people who get COVID report long COVID symptoms. About half of those go away after a few months, so 12.5% get persistent symptoms. Suppose that half of those cases (totally made-up number) are very mild and not worth worrying about. Then 6.25% of people who get COVID would have serious long-lasting Long COVID symptoms. After doing that calculation, I read this essay by Matt Bell, who tries to figure out the same thing. He is much more optimistic. He agrees that about half of long COVID cases go away after a few months, but adds another 50% decrease from “few months” to “lifelong”, kind of on priors, admitting there’s not too much positive evidence for this. Then he adds another factor-of-two decrease from vaccination, based on very preliminary studies from the UK. He estimates that someone with my demographics (vaccinated man in his 30s) has a 2% risk of Long COVID conditional on getting COVID at all. Then he divides by five for the true worst case scenario, based on studies showing that a fifth of people with Long COVID report that it affects their daily activities “a lot”. So by his final number, I have an 0.4% chance of getting really terrible long COVID, conditional on getting COVID at all. My friend AcesoUnderGlass also did a writeup of this, published after I did my first-draft calculation, which seems to be thinking of this very differently, based entirely on hospitalization rates (which of course are very low in vaccinated people our age). She accordingly concludes that risk is very low. I don’t really understand her reasoning here, but I trust her a lot and am working on trying to converge with her on this. What’s my yearly risk of getting COVID if I try to live a normal life? This site says only 0.1% of vaccinated Californians have gotten COVID after their vaccination. But vaccination was pretty new when that survey was done, so we might want to take this as a per one-to-two-months estimate. That would mean a risk of 0.5 - 1 percent per year. But not all these people are living normal lives, so my risk might be higher. MicroCOVID gives me a good sense of how careful I’d have to be to stay within a risk budget of 1% COVID risk per year. When I play around with it, I think I am about 5x - 10x less careful than that, which would mean a risk of about 5%/year. This tracker suggests my area has recently had about 1 new case per thousand people per week, which would imply 5% per year. But most of those people are probably unvaccinated, so my risk would be significantly lower than that. I’m going to round all of this off to about 1% - 10% per year of getting a breakthrough COVID case (though obviously this could change if the national picture got better or worse). Combined with the 0.4% to 6.25% risk of getting terrible long COVID conditional on getting COVID, that’s between a 1/150 - 1/25,000 chance of terrible long COVID per year. How does this compare to other risks? My ordinary risk of death per year, just from being a man in his 30s, is about 1/700 (though this includes drug abusers and stunt pilots, so my real risk might be lower, let’s say 1/1000). Here are some other risks, courtesy of the BMJ: In this context, I find the 1/150 risk pretty scary and the 1/25,000 risk not scary at all, so, darn, I guess there’s not yet enough data to have a strong sense of how concerned I should be. 9. This is hard to compare to other postviral syndromes Going into this, I wondered if we might be able to ignore Long COVID. The argument would go like this: all viral diseases have a risk of postviral syndromes. Colds, flus, mono, lots of stuff that’s going around all the time. Lots of people get those postviral syndromes, and either recover or don’t, but either way we don’t make a big deal out of it. Since COVID’s considered “newsworthy” in a way flu isn’t, we obsess over its postviral syndrome even though it’s no worse than anything else’s. This wouldn’t make Long COVID any less bad, and maybe we would be wrong to not panic more about colds and the flu, but it would at least give us some context and make things feel less scary. Unfortunately, I can’t find anything supporting or opposing this picture. The only relevant study is a meta-analysis by Poole-Wright et al, who (contra nominative determinism) don’t pool the studies by condition, which makes it hard to draw conclusions. I think all of their examples of postviral syndrome after flu are from severe hospitalized cases, so any comparison with COVID would be unfair. Although there do seem to be scattered reports of post-flu problems, they’ve never been formally studied or quantified. Mononucleosis is an infectious disease caused by the Epstein-Barr virus, affecting about 1/2000 people per year in developed countries. It has a famously nasty postviral syndrome, which this paper describes as “almost one-half of the group had substantial ongoing symptoms 2 months after onset and… ∼10% had disabling symptoms marked by fatigue lasting ≥ 6 months”. Flu is as common as COVID, but nobody really talks about it having a significant postviral syndrome so probably it’s not that bad. Mono has a worse postviral syndrome than COVID, but it’s rare enough that it doesn’t cause massive society-wide effects. COVID is right in the middle: more common than mono, and (probably) worse postviral syndrome than flu. I think it’s fair to say that we may not have encountered a condition with this exact combination of risk factors and can’t dismiss it as similar to conditions we currently ignore. One potential analogue might be the Spanish Flu of 1918. It was an equally widespread pandemic, and seemed to have some kind of postviral syndrome. From TIME: In what is now Tanzania, to the north, post-viral syndrome has been blamed for triggering the worst famine in a century—the so-called “famine of corms”—after debilitating lethargy prevented flu survivors from planting when the rains came at the end of 1918. “Agriculture suffered particular disruption because, not only did the epidemic coincide with the planting season in some parts of the country, but in others it came at the time for harvesting and sheep-shearing.” Kathleen Brant, who lived on a farm in Taranaki, New Zealand, told Rice, the historian, about the “legion” problems farmers in her district encountered following the pandemic, even though all patients survived: “The effects of loss of production were felt for a long time.” The 1918 flu seemed to have lots of psychiatric effects: “Norwegian demographer Svenn-Erik Mamelund provided such evidence when he combed the records of psychiatric institutions in his country to show that the average number of admissions showed a seven-fold increase in each of the six years following the pandemic, compared to earlier, non-pandemic years.” Coronavirus doesn’t - the excellent Amin-Chowdhury study above finds nothing. Still, this is the scale of thing I’m worried about. The worst case scenario here is really really bad. If a few percent of COVID patients get long-term unremitting genuine CFS/ME, that has the potential to overwhelm government welfare budgets and long-term depress the economy. I think there’s a 90% chance the real situation isn’t that bad, but it’s scary that we can’t entirely rule it out. Aside from the somewhat different 1918 case, I don’t think we have any historical experience of dealing with postviral syndromes at this scale. The medium case scenario is something more like “a few percent of infected people get moderate fatigue, which doesn’t really prevent them from working, and goes away after a few years”. I don’t know whether the level of media attention paid to this would converge on “boring and nobody notices” or “giant disaster”, and I think it would be compatible with either. 10. Conclusions 1. Long COVID is many different issues without a common mechanism. 2. Some of these are straightforward and not surprising, eg lung scarring and post-ICU syndrome from severe infection, and would happen in any disease of this severity. Others seem to be more like the poorly-understood postviral syndromes associated with several other diseases. While some symptoms may be psychosomatic, most are probably organic. 3 The three major categories of symptoms are straightforward cardiovascular-pulmonary issues, straightforward smell and taste issues, and more mysterious neurological issues. 4 Although these get better with time in some people, in a significant number (maybe ~50% of people who had them at six weeks) they persist for as long as anyone has been able to measure them (a few months in the case of COVID, a year or two in the case of comparable syndromes). 5. Post-COVID fatigue is particularly concerning. This would be very bad if we analogized it to CFS/ME, and still pretty bad if we analogized it to other known postviral syndromes. There is no proof that this always gets better over the long term, although no study has looked at them for more than a few years. Facing postviral fatigue on this scale is a new problem. 6 . Children probably get Long COVID less than adults, probably at a rate of less than 5% of symptomatic cases. But we don’t know how much less, and we can’t rule out that some children get pretty severe symptoms. 7. Although vaccination decreases the risk of symptomatic COVID, it probably doesn’t decrease the risk of Long COVID per symptomatic COVID case by very much, though it might decrease it by a factor of 2-3. 8. Your chance of really bad debilitating lifelong Long COVID, conditional on getting COVID, is probably somewhere between a few tenths of a percent, and a few percent. Your chance per year of getting it by living a normal lifestyle depends on what you consider a normal lifestyle and on the future course of the pandemic. For me, under reasonable assumptions, it’s probably well below one percent. EDIT: Here are some other people who tried to do this same analysis. I learned about all of these after I wrote the first draft of this, so you can consider the basic thought process here to be independent of them - but I edited some things to account for what I learned from them before writing the final version.

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.

28: Bryan Caplan - Anti-Woke: From Outrage To Action. He seems to be joining Richard Hanania’s position that existing interpretation of anti-discrimination law often boils down to “companies can be sued for not enforcing wokeness” and that the quickest way to solve the problem is to repeal the law. I am most skeptical of his second claim, that making hostile takeover of corporations easier would keep them focused on profitability rather than wokeness; although there are a few well-publicized examples of wokeness being bad for the bottom line, I’m not convinced this is generally true.

Some savants become obsessed with trains and become great engineers. Some become obsessed with computers and build software wonders. One of Abacha’s predecessors said of him: “He might not be bright upstairs, but he knows how to overthrow governments.” Kenyon elaborates: “It was as if Abacha was an idiot savant. Dull, even gormless, he filled his days with cowboy movies and sleeping off the previous night’s indulgences in alcohol and prostitutes. But he was possessed of a prodigious flair when it came to coups.” 8: Related to my previous subscribers-only post on the psychology of fantasy: Balioc’s Taxonomy Of What Magic Is Doing In Fantasy Books. See also Eliezer’s commentary. 9: New study on the timing of human mutations confirms Greg Cochran’s 2012 post about how after leaving Africa, modern humans were limited to “Arabia and surrounding regions” for ~30,000 - 50,000 years, racking up various new mutations and becoming adapted to life outside Africa (kabbalistically equivalent to the 40 years spent wandering in Sinai?). Most mutations in “fat storage, neural development, skin physiology, and cilia function”. 10: Iron Economist on Twitter: “Desalinization was one of the big technological success stories of the 2010s”. 11: Matt Bruenig argues against the Success Sequence, whose proponents (including Bryan Caplan) describe it as: 97% of Millennials who follow what has been called the “success sequence”—that is, who get at least a high school degree, work, and then marry before having any children, in that order—are not poor by the time they reach their prime young adult years (ages 28-34). Bruenig’s argument is mostly a lot of annoying “well maybe it’s just your cultural bias that makes you care about this”, but in the middle of this it mentions some genuinely strong points, especially that the research doesn’t measure “sequence”, but rather “current status”. So if you graduated, got a job, got married, and had children, but then lost your job, your would be counted as “not following the sequence” (same if you get divorced). Also, disabled and old people and their caretakers are excluded from the analysis, which in one sense is fair (your conclusion can be “abled young adults can avoid poverty through this method”) but in another sense risks reducing all of this to the more trivial-seeming statement “if you’re young, healthy, abled, married, don’t have to support anyone else, and have a full-time job, you’re probably not poor”. But the authors (channeled by Caplan) disagree: Some critics of the success sequence have argued that marriage does not matter once education and work status are controlled. The regression results indicate that after controlling for a range of background factors, the order of marriage and parenthood in Millennials’ lives is significantly associated with their financial well-being in the prime of young adulthood. Simply put, compared with the path of having a baby first, marrying before children more than doubles young adults’ odds of being in the middle or top income. Meanwhile, putting marriage first reduces the odds of young adults being in poverty by 60% (vs. having a baby first). The main thing I would want to look at here is how much of this is causal vs. just class selection: upper-class people are more likely to marry, less likely to divorce, and more likely to wait before having children. Has anyone followed some pre-selected group of equal class people (eg the population of some low-income school district) and seen how their own success varies with sequence compliance? 12: I’ve previously linked claims that vat-grown meat, freed from the tyranny of having to grow inside animals, will include tiger steaks, lion burgers, and the like. Once again global capitalism outpaces my wildest fantasies and offers burgers with woolly mammoth protein (so far just the myoglobin, not the meat). 13: The people who believed there was lots of gender bias in STEM academia, and the people who believed there wasn’t finally did an adversarial collaboration (a study co-conducted by two groups of scientists with conflicting theories, keeping each other honest). The results: Contrary to the omnipresent claims of sexism in these domains appearing in top journals and the media, our findings show that tenure-track women are at parity with tenure-track men in three domains (grant funding, journal acceptances, and recommendation letters) and are advantaged over men in a fourth domain (hiring). For teaching ratings and salaries, we found evidence of bias against women; although gender gaps in salary were much smaller than often claimed, they were nevertheless concerning. For ten years lots of important people told us again and again that discrimination against women in STEM was a massive problem. People who questioned its extent were accused of misogyny and sometimes fired, I got harassed and insulted for pointing out reasons the standard arguments didn’t seem to hold true. Millions of dollars were spent investigating and responding to the problem. And now I expect this pretty strong evidence that women were actually advantaged in hiring and had parity in most other things (the salary is probably just the usual negotiation issue) to produce no publicity, no apologies, and no soul-searching from the people leading the current round of anti-academia and anti-STEM inquisitions. Sorry, yes I am bitter, it just bothers me how much the people claiming that it’s urgently important that nobody is ever allowed to suggest they are wrong have a consistent track record of being totally and inexcusably wrong. 14: In my response to Sam Kriss, I speculated on what would happen if someone rewrote the MCU to sound like ancient myths.

Your Book Review: Secret Government

July 07, 2023 · Original source

Secrecy in government is only a problem, then, if we are fully committed to promissory representation. Kogelmann argues that we should reject the intuitive appeal of promissory representation because it will inevitably lead to pandering: politicians supporting policies they know to be bad or ineffective because of popular support. For an enumeration of all the ways in which expert opinion differs from lay opinion, see Bryan Caplan’s book The Myth of the Rational Voter. I would go further and argue that the reason citizens elect representatives in the first place is because of this difference of opinion. Citizens do not want to spend all of their time embroiled in the arcane details of healthcare regulation or fiscal policy. They want somebody else to do the work for them. The fact that opacity conflicts with promissory representation, then, is not a problem.

Contra The Social Model Of Disability

July 14, 2023 · Original source

The Social Model Of Disability came out of the same 60s/70s cultural current that gave us Thomas Szasz’s claim that mental disorders are fake. Szasz was thinking of examples like the stigmatization of homosexuality; he (understandably) preferred to think of homosexuality being a perfectly fine alternate-way-of-being that society just had to learn to accommodate. But he took it too far - and then Bryan Caplan took it even farther - and claimed that all mental disorders were just alternate-ways-of-being that society had to change to accommodate. There’s no such thing as drug addiction; people just voluntarily choose to use drugs. Society stigmatizes that choice by casting it as a disease where the person can’t control their drug use. But this is no more true than thinking of playing baseball as a disease where people can’t control their baseball use. Instead, society should admit that using drugs is fine.

Inline links: the same 60s/70s cultural current, Thomas Szasz’s, and then Bryan Caplan took it even farther

Nowadays this perspective has been abandoned by everyone except a few holdouts, Bryan Caplan, and the Scientologists; maybe it’s hard to take it seriously. But put yourself in the shoes of a 1970s radical. Your stereotype of psychiatric treatment, which wasn’t entirely false, would have been cops taking gays / LSD users / eccentrics, locking then up in horrible state-run hospitals for months, and treating them with strong drugs or electroshock therapy or lobotomies. You’d never met a schizophrenic, but you believed Gregory Bateson and Thomas Szasz’s report that they were just cool eccentric people who didn’t abide by society’s artificial rules. You and your comrades had just won a great victory in getting the medical establishment to de-list homosexuality as a mental disorder, and - sure enough - the problem had been society’s persecution of gays, not the “disorder” itself. Drunk with victory, you might see the arc of history pointing to the complete liberation of all categories of supposedly “mentally ill”. So why not the supposedly “physically ill” too? Why not liberate everybody?

The literal content of the Social Model of Disability as it’s usually presented is nonsense, but it’s attractive because it contains a useful insight: some conditions can be either life-ruining or completely fine, depending on how society accommodates them. A Biopsychosocial Model could continue to provide this insight, while jettisoning the less defensible elements. Together, We Can Reach Entirely New Levels Of Disagreeing With Bryan Caplan About Mental Illness The Social Model of Disability is similar to the Caplan model of mental illness.

On Priesthoods

January 08, 2025 · Original source

Society-wide: The marketplace of ideas! This is where everyone gets to have their say. New hypotheses get stress-tested, bounced off against each other, and only the strongest survive. This level also produces true learning - if only one idea survives the marketplace, then average spectators can easily pick it out (although of course it can still be wrong). Its disadvantage is that it’s impossible for several billion people to hold a true “discussion” among themselves. Also, many of these people are extremely stupid, their ideas are bad, and they fill the conversation with noise. Is there a useful group size in between these two? What about discussing ideas in a group made of only the most intelligent and knowledgeable people? This gives you the debate and collaboration functions that you only get in group conversation. But it’ll have a better signal-to-noise ratio than all of society, and it might be small enough to manage. Also, you can make people sign on to good discussion norms before they enter, and you can expel them if they screw up. The Boundary Against The Public From this formulation, it becomes clear that such a priesthood is only useful insofar as it has some kind of barrier between itself and the general public. The priesthoods don’t exactly hate the public. But they hate the idea of letting the public’s ideas mix with their own. It’s not just that they discount the public’s ideas insofar as the public is less sophisticated than themselves. Their whole identity comes from their separation from the public. Ideas that seem too similar to the public’s get actively penalized, the same way it would be hard to convince Democrats to accept a plan that Donald Trump proposed first, even if it otherwise fit with Democratic ideals. I recently reviewed Tom Wolfe’s From Bauhaus To Our House, on the architectural priesthood. It discusses the response when renegade architects would build things in styles favored by the public - for example, Edward Stone and the Kennedy Center: Stone and Saarinen, like Frank Lloyd Wright and Goff and Greene, were too American, which meant both too parochial (not part of the International Style) and too bourgeois. Somehow they actually catered to the hog-stomping Baroque exuberance of American civilization. When Stone designed the Kennedy Center in Washington with a lobby six stories high and six hundred and thirty feet long – so big, as one journalist pointed out, that Mickey Mantle’s mightiest home run would have been just another long fly ball – it was regarded as an obscenity. Stone was actually playing upto American megolomania. He was encouraging the barbaric yawps. He was glorifying The Client’s own grandiose sentiments. More generally: In a way, the very productivity of a man like Wright, Portman, or Stone counted against him, given the new mental atmosphere at the universities. Oh, it was easy enough, one supposed, to go out into the marketplace and wheedle and vamp and dance for clients and get buildings to do. But the brave soul was he who remained within the compound, stayed within the university orbit. Or, from the comments, this quote by architect Peter Eisenman: What I’m suggesting is that if we make people so comfortable in these nice little structures of yours, that we might lull them into thinking that everything’s all right, Jack, which it isn’t. And so the role of art or architecture might be just to remind people that everything wasn’t all right. I used to wonder why so many econ-bloggers I liked were at GMU. GMU only is only the 74th best economics department in the country, but more than half of the econbloggers I like are affiliated with it in some way (Tyler Cowen, Alex Tabarrok, Garett Jones, Robin Hanson, Bryan Caplan, Arnold Kling, Scott Sumner, Mark Koyama, sorry if I’m forgetting anyone!). Granted that some of this is because I lean libertarian and so do they - but I don’t think there’s a mountain of amazing and popular left-wing econbloggers who I’m ignoring. Part of this must be that Mercatus head Tyler Cowen is better at spotting and cultivating talent than others - but you’d still think the #73 ranked department would try to poach some of his hard work. When I asked academics about this, they didn’t find it mysterious at all. The average high-ranked economics department doesn’t care that you have a popular blog. They might even count it against you. Only your reputation within the priesthood matters. This is my experience too. I once got rejected from a psychiatry residency I wanted, partly because they saw I had a blog and thought it might cause trouble (though the less prestigious hospital that eventually accepted me did consider it a plus, for which I remain grateful). I wish I could say that the program which rejected me is kicking themselves right now - I’m probably one of the most-read psychiatrists in the world, and most of what I write is relatively orthodox and (I hope) reflects well on the field. But outside of my fantasies, they are doing nothing of the sort. At best, my blog has gone from a liability to being neutral or a very slight positive. Certainly it doesn’t make me as impressive as someone who went to a medical school one tier above mine. Consider how impressive a boundary this is - someone can have literally tens of thousands of fans for doing popular writing in a field, and the amount of extra status it gives them in the field is within a rounding error of zero. Only your reputation within the priesthood matters. Still, at least I’m a member in good standing. At least I’m higher than pond scum. The lowest-status doctor in the world - the guy who, if doctors were Maoist revolutionaries, would get his face on the “Criticize X, Criticize Y” posters - is Dr. Oz. This isn’t because Dr. Oz lacks medical skill. Back in the day, he was a professor of surgery at Columbia, and by all accounts quite good at it. But then he went on TV and started catering to the public. He told them their stupid miracle cures and $19.99 supplements were Real Medicine. Imagine a Catholic bishop declaring ex cathedra that The Da Vinci Code is 100% real. Authority bestowed to fight the heresies of a fallen world, instead used to prop up those heresies. Columbia recently “cut ties” with Oz in some vague way, but as far as the medical profession is concerned, it’s too little, too late. I think the profession’s hatred for Oz is justified - his claims are false and probably cause a lot of harm. But other doctors who say false harmful things get only a fraction of the hatred that Dr. Oz does. He’s not just defrauding and maybe killing the people who take his supplements. He’s sullying Medicine itself. This hard boundary - this contempt for two-way traffic with the public - might seem harsh to outsiders. But it’s an adaptive artifact produced by cultural evolution as it tries to breed priesthoods that can perform their epistemic function. The outside world is so much bigger than the priesthoods, so much richer, so full of delicious deposits of status waiting to be consumed - that any weaker border would soon be overrun, with all priesthood members trying to garner status with the public directly. Only the priesthoods that inculcated the most powerful contempt for the public survived to have good discussions and output trustworthy recommendations. The Boundary Against Capitalism Dr. Oz illustrates another point: power corrupts, and the priests (as people known to be more knowledgeable than the public) have the power to bless or damn interventions in their field. Without some boundary against capitalism, they would abuse that power to make money. Again, cultural evolution has produced such a boundary. A doctor who seems too mercenary loses status in the priesthood. My father - a much more orthodox (and hence higher-status) member of the medical priesthood than I will ever be - used to even get suspicious of concierge doctors. Was it really in keeping with the principles of medicine to care about the amount of money you got for your service? Shouldn’t the usual insurance payments (calculated behind the scenes, without you ever having to think about it) be enough for anybody? If you let doctors charge extra for their services, they might do bad medicine in order to increase profits. In the worst case scenario, they might flatter members of the public who wanted all-natural $19.99 supplements. This taboo has faded as insurance squeezes doctors harder; even my father eventually relented. But there’s still the sense that doctor is a calling in a way that used-car salesman isn’t. If you pursue money too aggressively, can we really be sure you’ve heard the call? Why doesn’t every doctor pursue their own $19.99 supplement business? Some of this is professional regulation - there’s a sense that probably the Medical Board will come down on you if you do something wrong (though most doctors are proudly ignorant of the exact limits of the Medical Board’s power - why should the pious worry about the exact boundaries of excommunicable offenses?) But most of the barrier comes from self-regulation based on social status. By the time you’re done with medical school and residency, all of your non-doctor friends have long since abandoned you, and all the old sources of status and approval that you used to crave have been excised and replaced with the all-seeing eye of the medical priesthood. If you sell out and start the supplement line, you might get a new Ferrari, but everyone whose opinion you respect will hold you in contempt. The public might think it’s cool that you have a Ferrari, but doctors know better: nobody with a supplement line has ever been cool. This doesn’t mean doctors are incorruptible. Plenty of them become pharma company shills. But that’s because being a pharma company shill doesn’t burn intra-priesthood respect the same way. For better or worse, pharma companies straddle the priesthood boundary. They may not be fellow priests, but they’re at least nuns or deacons or something. They won this by sacrificing certain capitalist parts of themselves (for example, becoming heavily regulated) and by agreeing to follow the norms of the medical priesthood (for example, communicating through papers published in medical journals with high-status doctors as lead authors). Through their sacrifice, they achieve ritual purity; now priests can interact with them guilt-free. Is ritual purity really the same as moral acceptability? Sounds like the kind of question a member of the public might ask! Communication Norms Within The Priesthoods Although priests talk normally when when they meet one another at the water cooler, ex cathedra communication must be performed in a ritually pure way. For the medical priesthood, that means papers published in a medical journal. Consider ritually impure communication - for example, Twitter. Someone may try to make a medical claim (“SSRIs are a great depression treatment!”). But one can’t even predict the genre the reply will take. It could be any of: Insult (“You’re just another a big pharma shill trying to poison us!”)

7: A common sociological claim is that relative income (compared to your social circle) matters more for happiness than absolute income. Bryan Caplan thinks this can’t be true: after all, practically nobody moves to poorer areas to enjoy the higher relative income this would confer. I don’t know if you can really use revealed preferences this way - exercise and meditation plausibly make you happier, but most people don’t do them. On the other hand, there are enough people who do them and praise them that we all know somebody like this. Where are the people who coincidentally ended up living in the slums and love it?

But their plan was stymied when the legislature “amended” the bill to remove its entire text and replace it with unrelated text about airplane loans. The legislator apparently got cold feet after being warned it might inflict collateral damage on other companies, and because of the way the California legislature works it’s sometimes more efficient to turn doomed bills into other bills than to simply withdraw them. 31: EthnoGuessr is a GeoGuessr variant: it shows you pictures of an ethnic group, you click on the map where you think they’re from.

Although they cite sources, I don’t understand the philosophical basis of the classification. Also, 100 images is so few that you start memorizing them after a while.

I feel about 75% sure there’s a trend towards recent intellectual decline which needs to be explained, I think phones are about 60% of the explanation, and I think it’s about 25% likely that early childhood phone use causes some damage beyond what would happen if you kept your kid away from phones until age 18 but then let him use them normally afterwards. When I multiply those all out, that’s an 11% chance that letting my kid use a phone will rot his brain. I can already hear Bryan Caplan saying that’s not so high - that living with a stressed-out parent who constantly resents the demandingness of childcare has a much more than 11% chance of being bad.

This whole time I was reading Selfish Reasons To Have More Kids, when I should have been waiting for Pro-Market And Pro-Business (released last month, now available on Amazon). There really is a Bryan Caplan book for everything!

In the same way, I think if Tyler had the experiences I’ve had, he would not so casually write a handwavy four-line post vaguely insinuating slanders on USAID while protesting that he never quite said them clearly. If someone told him the post was misleading, he would care a lot about this, rather than acting like one of the most worth-worrying-about points was whether overly strong criticism of Trump might lead to his assassination. He wouldn’t be so breezy about a “radical clearing away of NGO relations”, or engage with the destruction of the charity ecosystem on the level of faux-profound slogans. Maybe Tyler is much nicer and more rational than I am and able to treat this whole situation with perfect Zen calm. But to me, it comes across as a sort of “missing mood” in the Bryan Caplan sense.

Your Review: Alpha School

June 27, 2025 · Original source

Why this time might be different: Most promising educational initiatives fail to have impact when expanded beyond their initial studies. Bryan Caplan might argue this is because most education education is just signaling anyway (“The Case Against Education”). He also argues that most parental interventions have no impact (“Selfish Reasons to Have More Kids”) – He claims that how kids turn out is a combination of genetics and non-shared environment (randomness; nothing to do with parenting choices). How can we reconcile Caplan’s buttoned-up data with the idea that the “parenting choice” to educate your kids differently (like with Alpha) might result in different outcomes than would be expected from genetics alone? WHY could Alpha work?

Inline links: The Case Against Education, Selfish Reasons to Have More Kids

They keep the kids motivated so they put in the daily effort and don’t get burned out What Alpha is doing is not rocket science. They are just “following the science” for what has been proven to work, and then designing a school around the best way (or “a way”) to deliver that science - personalized instruction, mastery focus, spaced repetition and incentives. It should not be too surprising that when it all comes together it spits out measurable results. But will it hold? Part Six: A Response to Bryan Caplan "When the data and anecdotes disagree, the anecdotes are usually right. It’s usually not that the data is being miscollected. It’s usually that you’re not measuring the right thing." — Jeff Bezos (on multiple occasions) Not only does Bryan Caplan convincingly argue that education is mostly signalling in his book “The Case Against Education”, he goes even further to pour cold buckets of water on aspirational parents in his book “Selfish Reasons to have more Kids”. In that latter book he makes a compelling case with unimpeachable data that how kids turn out is almost entirely due to their genes plus “non-shared environment” (i.e., random things not having to do with parenting). According to Caplan helicopter-parenting does not hurt your kids, it is just a waste of everyone’s time (and maybe their enjoyment during their childhood). You might be able to influence some of your kids' behavior in the short term, but once they become an adult and move out of your house they will revert to the biases of their genes. As Caplan says, the most important parenting decision you can make that will affect how your kids turn out is your choice of spouse (or more accurately your choice of the genes you use to build your kids). Caplan does put one caveat on his data: range restriction. He admits that all of his adoption studies focus on middle class Americans (and Europeans). He is the first to admit that if you take a baby out of extreme poverty in the developing world and raise him in a middle class American family, he will have better economic outcomes than if you leave him in rural Mauritania (see his “Open Borders” book). He may even grant that moving from the poorest broken families in America to the middle class also may make a difference – since all the data available comes from families who were approved by administrators as acceptable to raise adopted kids. But is the same thing true when you move from the middle of the bell curve to the right? When the Data Set Gets Bigger Raj Chetty’s neighbourhood-impact study cracked the range challenge open. Chetty had access to all IRS filing data for generations. He was able to focus on families with multiple children that moved to significantly different zip codes, and follow those children over extended periods of time. By having millions of data points he could tease apart the impact of moving to a “better” zip code for older vs younger siblings. The younger sibling had the same family environment (and 50% of the same genes), but some number of more years in the “better” neighborhood. Chetty found that better neighborhoods made a difference to long term outcomes. But isn’t the neighborhood where a family lives in a “shared environment”? Clearly some adopted families lived in better neighborhoods than others? Why didn’t Caplan’s adoption studies pick that up? I think part of the answer is noise. Chetty had millions of data points vs hundreds of thousands for the adoption studies. But mostly I think the reason Chetty found this impact while the adoption studies did not is that he was looking for different things. No one took the adoption studies and grouped the zip codes as the relevant input variable. As Bezos says, the data wasn’t miscollected, they were just looking at the wrong things. So what does a good zip code look like? Chetty summarizes a good zip code as: Short commutes

Low single mother rate He summarizes that as a place of “economic connectedness” – where adults are connected to each other and to the broader community. A lack of those five elements are not bad per se, but they are correlated with a community where people are not interacting with each other as much as they are in communities where the metrics are reversed. Chetty frames it that kids are influenced by the other adults in the area they live in. But I have another hypothesis. Rather than: Other parents → Your kids Perhaps the causation runs from: Other parents → You → Your kids Maybe it’s not other parents' style of parenting that is influencing your kids (how?) but rather when you spend time around other parents their parenting style rubs off on you and how you parent your kids. Influence like that will not get picked up in Caplan’s adoption studies (which focus almost on how parent characteristics get passed on to genetic vs adopted children’s characteristics), but it is a potential signal that maybe parenting choices do matter. Maybe we were just looking at the wrong data. Pre-registered Genius Experiment We now have two data sets that don’t contradict directly, but do point to opposing conclusions. It would be great if we could test this with a pre-registered randomized control trial. That is not going to happen in our current culture. But enter Laszlo Polgár, who volunteered his own children as the test subjects. (Scott’s 2017 review of Polgar’s book here) Before his children were born Polgár publicly announced he would raise them to be geniuses. He initially considered training them to be genius artists, writers or mathematicians, but decided those fields were not objective enough. It would be too easy for critics to dismiss his future children’s achievements and “not genius” no matter what they accomplished in those fields. So he chose a field that was considered both “driven by intelligence” that had clear, objective measures: chess. Then he called his shot. By 1989 all three girls received their first “GM norms” (a GM norm is finishing a tournament with a elo score of at least 2600; 27 norms are needed to make grandmaster). Two went on to become grandmasters - the 3rd and 4th women to ever achieve that title. One ranked in the top 100 (all genders) at age 12 – she peaked at #8 in the world. The other became the top-rated woman in the world at age 15. Polgar showed that you could take kids, at least kids with “good enough genes”, and turn them into world champions through the right education methods. One might think this would be “case closed”, but even as the Polgar sisters were achieving these feats people were saying that these girls must have been “naturally gifted”. They clearly had bright parents, but does anyone think that if they had been adopted into a random middle class American household they would have still become chess geniuses? Or world class in anything at all? When Polgar was challenged on exactly that, he wanted to repeat the experiment by adopting a “black child” and doing it again. Unfortunately his wife talked him out of it. Even if he had adopted a child and turned him into a genius, that would just be one data point – it would not show up in Caplan’s adoption studies. It would be a case of the anecdote and the data disagreeing. Which do you choose to believe? Aristocratic Tutoring It would be great if we could find more examples of Polgar’s model. While I could not find any other “called shots”, one could go back and look at the childhoods of geniuses to see if there is anything to find. That is what Erik Hoel did in his series of posts on “Why we stopped making Einsteins” (post 1, post 2, post 3; Scott’s response). Hoel argues persuasively that, when biographies of their childhoods exist, the geniuses of the past were almost all given 1:1 tutoring. There must have been many aristocrats in the past that were given 1:1 tutoring who never amounted to world-class genius, and many world-class geniuses who got there without 1:1 tutoring, but it does seem to put the thumb on the scale. Benjamin Bloom would agree. Benjamin Bloom quantified Polgar’s hunch in 1984, just eight years after Polgar’s last daughter was born. He ran a RCT where some students were taught normally and others given 1:1 tutoring. He found that the average tutored child improved by two standard deviations over the control: “The average tutored student was above 98% of the students in the control class” and “about 90% of the tutored students ... attained the level reached by only the highest 20% [of the control]”. He called his finding the “Bloom’s 2 sigma problem” Why would this discovery of the secret sauce that could turn the average student into a genius be a problem? Because Bloom saw no way to scale it. Clearly we can’t give every kid in the world a personal 1:1 tutor. We had the solution that would revolutionize everything, but it was just too expensive. Where does that leave us? Caplan showed that, within the normal range, nothing you do in education or parenting matters. …But Chetty showed that how (or at least where) your kids are raised can matter. …Polgar showed that intense 1:1 tutoring from a young age can create world-class geniuses …And Bloom showed that 1:1 tutoring can work for almost everyone, improving performance, if not to world-class levels, still two standard deviations above the alternative. Caplan is still mostly right—if you hover in the complacent middle of American schooling. But Chetty hints that context nudges outcomes, Polgár proves that deliberate, early, personalised instruction can manufacture prodigies, and Bloom tells us it lifts the average child by two sigmas. Alpha’s claim is that software‑mediated, 5:1 tutoring narrows that two‑sigma gap for a price mere mortals can (barely) contemplate. Whether that vision survives contact with budgets, regulators, and human nature is the question for section seven. Part Seven: Scaling Weird A month into our experiment in Austin we were at a neighbor’s backyard pool party (a fringe benefit of moving to Austin: there were backyard pool parties in early November). I was in conversation with a couple that I had just been introduced to. He asked why we moved to Austin, “Was it for your job?” “No. Actually we moved for a school for the kids.” Their faces expressed a combination of confusion and shock. It wasn’t the first nor the last time. Everyone is confused at why we would move across the country to send our kids to a new school, “They don’t have good schools where you come from? How much does this school cost?” Those two questions frame Alpha’s biggest risks when it comes to scaling. Their biggest challenges going forward are not going to be pedagogical. They are going to be sociological and economic. The Economic Problem Alpha is much cheaper than a Victorian Governess, but it’s not cheap. As mentioned in this review more than a few times, Alpha’s flagship campus charges $40,000 a year— roughly 3-4× what the other top-tier private elementary schools in Austin ask. Yes, that figure is all‑in: every Chromebook, every afternoon workshop, even the spring junket to Poland to beta‑test the platform with Ukrainian refugees is baked into tuition. There are no gala auctions or booster fees waiting in tall grass. Still, $40k is a hard swallow when the local Christian school will take your child for eleven. Worse, the number almost certainly fails to cover costs. Recall that guides start at $60k, rise to $100k on promotion, and the five “head guides” each earn $150k. At the five‑to‑one student‑to‑teacher ratio Alpha runs, those salaries alone suck in half the revenue from a twenty‑kid cohort before you’ve paid the rent, the head of school, the company executives, the curriculum designers, the engineers that are building the 2-hour platform and AlphaRead, the workshop costs (or the trip to Ukraine) or the marketing expenses (MacKenzie has a very well produced podcast, and I see a lot of ads for the school on Facebook now that we live locally). Compared with aristocratic one‑to‑one tutoring, forty grand is a steal. But $40,000 is still Lamborghini kindergarten – and even at those prices it is still burning through Joe Liemandt’s cash pile. Alpha’s answer to eventually solving the economics seems to be two fold: (1) Get enough scale that the fixed costs (like the learning platform) become a rounding error on overall costs, and (2) pull out the “non-essentials” at many of the campuses to get the marginal cost well below $10,000 per student. Whether they will be successful is still in early innings. The homeschool product beta is limping along with 1x learning, and the Arizona Charter doesn’t open until autumn 2025. Whether Alpha retains its magic without $150,000/year guides with 5:1 teacher:student ratios and generous bribe incentives programs, remains to be seen.
