14: You’ve probably heard statistics about how 50% of transgender youth attempt suicide before age 21. This paper tries to analyze the situation in more depth. The 50% number usually comes from surveys, but there’s some evidence people exaggerate on surveys, rounding up “I think about it a lot” to “I attempted”. The authors gather data on completed suicides among trans people, and find that they’re about 0.01%/year (which is about 5x the cisgender rate). If we suppose that people have about 5 years between becoming transgender and turning 21, then the 50% attempted suicide rate → 0.05% completed suicide rate implies that 1/1000th of the youth who report attempting suicide on surveys complete suicide - which sounds about right to me [but see this comment for a critique] 15: Gwern on the failures of 20th century eugenics. I’ve previously linked a piece about how, aside from the general moral failure, the 20th century eugenicists got lots of implementation details really wrong. Gwern adds to the picture: they had a purely Mendelian (as opposed to polygenic) model of intelligence, and felt that bad traits were probably caused by single recessive genes. This dichotomized the population in a way that contributed to the moral problems - if IQ is truly a continuum, then someone with 120 IQ might still wonder if they were “inferior” to someone with 130 IQ, in a way that made them feel some sympathy to someone with 80 IQ who was being pronounced “inferior” by the eugenicists of the time. But instead, they thought some people had the specific recessive “low intelligence” gene, those people could be “cleansed” from the population, and then everyone else would be fine! It also prevented them from considering improving the populace by encouraging intelligent people to breed more (as opposed to sterilizing unintelligent people) - this wouldn’t eliminate the recessive variants that were causing all the trouble! I’m confused how they could have believed this even with the limited knowledge of the time; this was long after Galton had proven that genius was genetic, and once you have genetic genius you know there’s more going on than Mendelian inheritance of subnormality. 16: Sexual selection bridges peaks in adaptive fitness landscapes 17: NFTorah: “The Torah [is] the original blockchain”. I think it’s funny that this exists, but it’s exactly what you would expect, and you don’t have to click on the link. 18: More IRB nightmares. 19: @ethanbdm When we piloted a public lottery to evaluate cash transfers in Liberia, the potential recipients arranged beforehand to insure one another. After the randomization and grant, the winners compensated the losers and unraveled the field experiment.","username":"cblatts","name":"Chris Blattman","profile_image_url":"","date":"Tue Jan 18 19:01:29 +0000 2022","photos":[],"quoted_tweet":{},"reply_count":0,"retweet_count":77,"like_count":678,"impression_count":0,"expanded_url":{},"video_url":null,"belowTheFold":true}" data-component-name="Twitter2ToDOM"> 20: DeepMind made a programming AI that was able to participate in a human coding competition and place around the middle.

If they invested less due to the tax, then workers might have received lower wages.

Del Giudice and Gangestad have a rebuttal saying that they were underpowered to detect it even if it did exist, plus noting the ways that media coverage of this study was incredibly irresponsible even by its own terms. 26: Some recent critiques of Cook (2014) on racial violence vs. black patents, including Michael Wiebe challenging the violence measures and AnechoicMedia arguing that the black patent measure declines right when switching from one (more complete) dataset to another (less complete) one. Rebuttal by Brad DeLong here, he argues that Cook uses multiple methods and some of them don’t have this problem. Relevant since Cook is now being considered for the Federal Reserve; see eg this Wall Street Journal editorial against. 27: Claim: 31% of British people say they have seen or met Queen Elizabeth (this seems plausible to me, I would answer ‘yes’ to this because she visited Ireland when I lived there, I watched the parade in her honor, and I could vaguely glimpse her on the inside of her car). 28: This couple-of-month-period in wokeness: Scientific American attacks late biologist EO Wilson, in a screed whose highlight is calling him problematic for describing ants as having “colonies”. This is part of a more general (and surprisingly fast) pivot at Scientific American from real science to culture warring; when even Eric Turkheimer thinks you’ve gotten too woke, you’ve gotten too woke.

37: Scott Sumner on the neoliberal wave of the 1970s. I would still like to see a good analysis of whether the neoliberal wave was inevitable (because the mid-century statist policies which seemed to work so well for so long were unsustainable) or an overreaction to a contingent recession and if we hadn’t done it we could have returned to mid-century-style statist policies and they would have gone back to working well. I suspect inevitable but I haven’t seen any really good treatments of this question.

Kangbashi, China’s most famous ghost city. What are housing prices like in the ghost city? Again from Bloomberg: Sitting on the southern outskirts of Inner Mongolia’s Ordos City (population 2.2 million), Kangbashi was the archetypal ghost city 10 years ago, with barren boulevards and empty buildings standing forlornly in the desert. Local officials are adamant that things have changed. They say 91% of homes in the district are occupied. In fact, after a yearslong construction freeze, the government approved six housing projects in 2020 and expects 3,000 homes to be built by the end of this year. Apartments in a new development are selling for 9,500 yuan per square meter, and downtown they go for 15,000 to 16,000 yuan, according to Liu Yueyue, 28, a salesman at a new residential development in the district’s northeast. “Would houses in a ghost town sell at such high prices?” asks Liu. Half of his customers come from outside Kangbashi, and most are parents who want to send their children to the well-regarded local schools, he says. Looking at this list of real estate prices across Chinese cities, Kangbashi seems squarely in the middle - for example, Wuhan and Xian are also in the 15,000 - 16,000 range. I claim this supports my argument: surely twenty years ago, houses in this particular deserted corner of Inner Mongolia would have been dirt cheap (if any even existed). But if you build a city there, it becomes just as expensive as any other city! Here it’s very obvious that the density caused the high prices instead of the other way around. Still, the Chinese housing market is weird, with significant vacancies even in expensive, well-developed cities. Paul Botts: No official vacancy rates are published in China and no specific definition of it exists there. Various think tanks and researchers both within that country and elsewhere have published estimates ranging from as low as 11 percent to as high as 24 percent. Those estimates have been for varying samples of Chinese cities, have used various definitions of housing vacancy rate, etc. The best (as in most systematic) estimate yet produced has come from researchers at a university in Liaoning. They used night-time urban lightsheds captured by a new (2018 launch) Chinese satellite having a new level of light sensing technology which allows separating out light from parks and plazas. They covered a large sample (49 cities), and made their sample representative of city type, city size, regions within China, etc. They also crossed-referenced with local housing data to ensure accurate balancing of their sample and to confirm that the satellite was successfully identifying light coming from housing blocks. They found vacancy rates of just under 20 percent in China's Tier 1 cities, and found rates above 20 percent in 40 of the 49 cities. They found the highest vacancy rates in western and northeastern cities, which are also the newest ones; that finding is consistent with the hypothesis of significant numbers of recently-built ghost cities. https://www.researchgate.net/publication/345092218_Housing_Vacancy_Rate_in_Major_Cities_in_China_Perspectives_from_Nighttime_Light_Data And Phil H (author of the blog Tang Poetry) writes: The price of housing in China has skyrocketed over the past few decades, as all those extra apartments have been built. I live in a pleasant but unremarkable southern city, and I paid London prices (about 4.5m yuan/$650k for a 1,300 sq ft flat). That seems to match Scott's hypothesis that high density leads to high prices. House prices here have risen much faster than incomes. They've risen in rural areas, too, but the increases in price in cities have been stratospheric. 4. Comments Accusing Me Of Not Considering Tokyo, Even Though I Included A Section In The Post On Why I Didn’t Think Tokyo Was Relevant I won’t name and shame people, but for example: You excluded Tokyo from your dataset. Tokyo has much higher density than SF and much lower price per sqft. Tokyo just kills this. Tokyo is bigger than New York and has significantly lower rent because they build more housing! This is in a wealthy country with even lower interest rates than the US. I don't think you have justified excluding non-US metros, like Tokyo, or Auckland. Doesn't this lead to the natural conclusion that there is a sufficient level of housing to build, and that the problem is that the USA's many metros are structured to prevent housing? It seems like you're just arguing that US metros are bad at building housing, which is also what Matt Yglesias is arguing. "Change my mind about housing, but don't mention Tokyo" is like saying "Change my mind about gun possession, but don't mention Switzerland." You can't test the effect of allowing new housing unless you're willing to look at cities that do, in fact, allow it. Tokyo and NYC both attract tons of new residents But Tokyo's housing rents have been stable, while NYC rents keep rising. Why? Tokyo has permissive housing construction laws. NYC makes building new housing almost illegal. Yes, dense cities are attractive, and that makes them get more dense over time. But it only makes them more expensive if you forbid new housing to keep up with the new residents. Tokyo! But I’m like the 10th person to bring it up… As I wrote on the original post (not even edited in! it’s been there the whole time!): I worry someone will bring up Tokyo as a counterexample. But I think Tokyo managed to build its way to low housing prices in the context of the rest of Japan also having good housing policy. Even if that isn’t true, Tokyo on its own is a quarter of the Japanese market, so it might be able to exhaust the entire pool of Japanese house-seekers by itself! That is, yes, you’re all correct that cities are only expensive in the context of more demand for city housing than the (NIMBY-constrained) city housing market can currently supply. You are all correct that if this problem were solved at the national level, then city housing would be cheap, and every additional city house would make it cheaper. My claim is that marginal changes - like Oakland building an extra 10,000 units, but everyone else staying the same - will most likely increase Oakland prices. Yes, if Oakland unilaterally built 50 million units, that would soak up the entire excess demand and probably lower prices everywhere (including Oakland). Yes, if the entire US switched to good housing policy at the same time, that would probably lower prices everywhere (including Oakland). But if we don’t do any of that stuff, and just build another 10,000 houses in Oakland, I think it would probably increase prices in Oakland. Some other people brought up that Japan has a declining population, and it’s much easier to have low house prices when your population is declining (compared to some previous time when number of houses presumably matched number of people), but ddd pointed out that people continue to migrate from the Japanese countryside to Tokyo, so its population continues to increase. Also, Mike (I’m stitching together two comments here): In a country with a declining population, you would expect that fewer homes are being built per capita because there's little to no competition for existing homes. But it's exactly the opposite! Japan builds far more homes per capita than the US does, despite their declining population […] As a result, the average Japanese home is very new and the average house is torn down and replaced after a relatively short 30 years. They're living in nice new homes for cheaper. 5. Comments Accusing Me Of Not Understanding Economics Maximum Limelihood Estimator writes: I think you're making a very common mistake here of confusing supply/demand with *quantity* supplied or quantity demanded. (This is very common! we teach students about this in micro 101 because it's so easy to make!) What you're seeing is that the quantity supplied is correlated with housing prices (true!). But this is very different from establishing that the supply curve--i.e. the amount of housing that would be produced at any given price, and what moves up/down when we regulate/deregulate supply--is positively correlated with price. Figuring out what supply curves look like is a lot less intuitive and requires some high-grade econometrics, which is why economists had to set up a whole commission just to study this particular problem (the Cowles Commission). In terms of resources for understanding how these concepts are different, a micro 101 textbook will cover this distinction. For the econometrics side of this, I've heard good things about Scott Cunningham's *Causal Inference Mixtape*, although I haven't personally used it. My claim is that increasing density within a city shifts the demand curve for housing within that city, because of increasing desirability. MLE later gets more on point: The effect you're discussing here is kind of real in a sense. When the marginal utility of housing increases for *other* people, density arguably becomes more desirable for me, which is kind of like the demand curve shifting up. These are called bandwagon goods and discussed here: http://econfac.bsu.edu/research/workingpapers/bsuecwp200804gisser.pdf In theory, the bandwagon effect could be so strong that parts of the demand curve are upward-sloping. Solutions like this are not, technically, prohibited by the laws of mathematics, just the laws of economics. (And arguably of physics--see paper for conditions where these kinds of bandwagon effects imply the amount of housing in the city would have to be negative). In practice, this effect exists but just can't overcome the normal, non-weird economics that says "making more of a good makes the prices fall." Again, I claim the existence of Manhattan vs. Conanicut shows that sometimes it does. I cannot find the words “housing”, “real estate”, or “land value” anywhere in that paper. Alex Poterack writes: There's two things going on here: confusing shifts in demand with movement along the demand curve, and getting causation backwards. You're assuming density causes prosperity, rather than prosperity causing density. There are ways the former can happen, but the bigger thing is that, for a wide range of historical reasons, you can make a lot of money in NYC and SF, so lots of people want to live there, so they get very dense. This is the prosperity shifting demand right, so at any given price, more people want to live there; this drives prices up, and they go higher the more fixed supply is. If you built a bunch of housing in Oakland, lots of people would move there because it's cheaper, which is movement along the demand curve; it's still the same number of people who want to live there at any price. Now, it's possible that the increased number of people living there makes the city more prosperous (this is the phenomenon of induced demand), which would shift demand right, but there are way more differences between NYC/SF and Oakland than just the density, so I don't think it would shift demand enough to offset this. In particular, if it's just a small increase in small, it's also a small increase in density, so there's almost no shift in demand (but there is movement along the curve). I still think this is missing my point, but I present it here in case anyone else is enlightened by it and wants to try further to convince me I’m making this mistake. 6. Comments By Famous People Who Potentially Have Good Opinions Scott Sumner is an economist and blogger; he writes: It is certainly the case that building more housing can make a city more desirable, and that this effect could be so strong that it overwhelms the price depressing impact of a greater quantity supplied. But studies suggest that this is not generally the case. Texas provides a nice case study. Among Texas’s big metro areas, Austin has the tightest restrictions on building and Houston is the most willing to allow dense infill development. Even though Houston is the larger city, house prices are far higher in Austin: Houston pretty much describes the “Oakland with more housing” outcome that Alexander views as somewhat far-fetched. Only in this case, it’s Austin with more housing. Alexander seems too quick to accept the, “If you build it they will come” idea—that you can build more housing and thereby boost demand so much that prices actually rise. I started the post with a graph of about 50 cities, showing a positive correlation between density and price. I’m having trouble seeing how Sumner’s point isn’t just “if you remove 48 of those cities and cherry-pick two, the relationship is negative”. My attempt to place Austin and Houston on the original graph, using Sumner’s data plus a few other things available online. Why weren’t they on there already? Maybe because the graph is metro areas and Sumner was talking about Austin and Houston as cities, but I’m not sure and agree this is confusing. Everyone knows Austin is more expensive than Houston because Austin is a trendy tech and culture hub and Houston isn’t (and relatedly, because Austin’s median family income is 50% higher than Houston’s). Unless someone wants to claim that its failure to build housing helped turn it into a trendy tech and culture hub, I don’t think there’s much point to this comparison. It’s true that Houston’s bigger size didn’t let it leapfrog over Austin to become a trendy tech and culture hub, which goes against some of what I claimed in the first part of this post. But I never claimed there would be a perfect 1-1 correlation between city size and trendiness, or that you could never find a pair of cities where one was bigger but the other was more trendy. Just that there would be a correlation. Moving on: Here’s the problem with this argument. It mixes up population change due to economic effects such as the benefits of agglomeration, with population changes due to regulatory changes such as less strict zoning. If you look at things this way, then the stylized facts work against Alexander’s argument. Over the past 50 years, increasingly strict zoning has reduced housing construction on big cities like New York and San Francisco. As a result, their populations have increased by less than in cities with less strict zoning, such as Houston. If Alexander were correct, then the price gap between the tightly controlled cities on the coast and the more laissez-faire cities of Middle America should have shrunk over time. Instead, the price gap has widened. New York and San Francisco were always more expensive than other cites, but with tighter zoning and less new construction the gap has become far wider. During the last fifty years, there was also deindustrialization and demographic sorting. This is just the Austin vs. Houston story all over again. Alexander is implicitly viewing this outcome as a “problem” for the city that builds more housing. They must sacrifice so that the rest of the country can gain. But in his scenario, Oakland is better off. Indeed if it were not better off, then why would more people choose to live in Oakland? In order for it to be true that building more housing boosts housing prices, it must also be true that the quality of existing houses (including neighborhood effects) rises by more than enough to offset the increase in supply. That means the new housing construction must make Oakland such a desirable place to live that the amenity effect overwhelms the quantity effect [...] Of course, economic change always has winners and losers. Here’s how I would describe the impact of allowing more housing construction in Oakland, in the unlikely event that this did raise housing prices: 1. America would benefit. 2. Oakland would benefit. 3. Poor people in America would benefit, in aggregate. 4. Affluent people in America would benefit, in aggregate. 5. Homeowners in Oakland would benefit. 6. Some renters in Oakland would benefit (from a more economically dynamic city.) 7. Some renters in Oakland would suffer from higher rents. In the much more likely case where new housing construction would lower prices, the impact described in #5 and #7 might reverse. Either way, there is no defensible argument for not building more housing in Oakland, regardless of the impact on price. If building more housing reduces its price, then there is a strong argument for allowing more housing construction. If building more housing raises its price, then the argument for more construction is even stronger. I agree with all this. Jeremiah Johnson is a co-founder of the Center for New Liberalism, host of the Neoliberal Podcast, and a YIMBY activist (not to be confused with Jeremiah “Liver-Eating” Johnson, who killed 300 Native Americans and ate their livers). He writes: Here's why you're wrong in a single sentence: Demand causes high prices, not new units. Prices are high in SF and NYC because those are desirable places to live for a huge number of people. People all over the country and the world would live there if they could, and prices reflect that. The fact that the densest cities are the most expensive is true. But the high prices are not caused by density - rather, the density and the high prices are both a consequence of crushingly high demand […] There's a feedback loop, but what matters here is the elasticity, which is less than one. We can measure this empirically. New housing lowers prices via the mechanism of adding supply, which is basic economics and how we expect markets to work. New housing could raise prices if it also made the city a more desirable place to live and shifted people's preferences, such that there was more demand to live there after the new housing is built. If you think it's unclear which of these effects would dominate, luckily we have empirical data that over and over and over shows adding housing supply does indeed lower prices on a local level. This is a fairly well established result that replicates well. edit: I'm actually thinking about drawing out the weighted DAG graphs here to make the conceptual stuff easier, but it would be pretty long. I'd love to do this as a guest post. I’m skeptical of the empirical results because they don’t match the much stronger “Manhattan vs. Conanicut island” empirical results, and if I try to think about why, the best explanation I can think of is that the Manhattan experiment has been going on longer (ie long enough for Manhattan’s extra residents to found businesses and institutions that attract new people). I’ve told him he can try pitching this guest post to me; in either case, I would be interested in seeing the graphs. Several other people also posted this graph that Johnson helped make famous: Hopefully by now you can predict my objection: the places in the southeast corner are mostly unfashionable red state Sun Belt cities; the places in the northwest corner are mostly trendy liberal coastal cities. My conclusion is that trendy liberal coastal cities are both more NIMBY and more desirable, and if you use this to draw any conclusions about housing policy you’ll just end up confused. But maybe I should take this same lesson to heart myself. Dense cities are mostly trendy liberal coastal cities; uninhabited tundra in North Dakota isn’t. Maybe the demand is just for trendy liberal coastal cities, and once you attain that status, extra density doesn’t matter that much. Maybe Oakland has already maxed out its “trendy liberal coastal city” status, and even if it became Manhattan-sized, it wouldn’t get any trendier, or would get trendier only with a long time lag. There are a few very trendy small coastal villages in California (think eg Sea Ranch); maybe these (rather than North Dakota) are the natural control group for San Francisco. I think they are still cheaper than SF, but maybe not by very much. Cameron Murray is a housing economist whose work some other commenters recommended; he also writes the blog Fresh Economic Thinking. He very kindly showed up and wrote: I think you are in general right that agglomeration effects are real, which is why bigger cities have higher value to residents. I agree that people move locations. But I think you can go a step further. If one city is growing faster and densifying, surely those people are not demanding homes in other cities and those cities build slower. This is part of the spatial equilibrium story that further makes claims about “build density and get cheap homes” less plausible. 7. My Final Thoughts + Poll Thanks to everyone who commented on this post and helped me refine my thoughts. I’m willing to concede the following points: It might be that only attracting the sort of educated people who found companies, universities, etc will make housing prices go up. Less educated people will take more jobs than they create and not ratchet up the city’s desirability level. (I’d previously told commenters talking about “gentrification” that it was irrelevant to the mechanism I was talking about here, but maybe it isn’t - maybe “gentrifiers” are the people creating more jobs and institutions than they consume, and so homes that attract them in particular will increase demand more than they increase supply? Maybe this discussion does reduce to the gentrification discussion?)

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!”)
