Teach debugging
A friend of mine and I couldn't understand why some people were having so much trouble; the material seemed like common sense. The Feynman Method was the only tool we needed.

1. Write down the problem
2. Think real hard
3. Write down the solution

The Feynman Method failed us on the last project: the design of a divider, a real-world-scale project an order of magnitude more complex than anything we'd been asked to tackle before. On the day he assigned the project, the professor exhorted us to begin early. Over the next few weeks, we heard rumors that some of our classmates worked day and night without making progress.

...

And then, just after midnight, a number of our newfound buddies from dinner reported successes. Half of those who started from scratch had working designs. Others were despondent, because their design was still broken in some subtle, non-obvious way. As I talked with one of those students, I began poring over his design. And after a few minutes, I realized that the Feynman method wasn't the only way forward: it should be possible to systematically apply a mechanical technique repeatedly to find the source of our problems. Beneath all the abstractions, our projects consisted purely of NAND gates (woe to those who dug around our toolbox enough to uncover dynamic logic), which outputs a 0 only when both inputs are 1. If the correct output is 0, both inputs should be 1. The input that isn't is in error, an error that is, itself, the output of a NAND gate where at least one input is 0 when it should be 1. We applied this method recursively, finding the source of all the problems in both our designs in under half an hour.

See this thread for our new study on polygenic scores within fraternal twin pairs! Main point: take extra care with polygenic scores for traits like IQ & education, because they're confounded by (what seem to be) socioeconomic status effects. Not so for traits like height & BMI.
The idea is that the parenting is caused by the parental genotype, so it gets (mis)classified as a genetic effect on the children. It's really another way of looking at "genetic nurture" - see the papers from last year.

Sci-Hub | The genetics of human fertility. Current Opinion in Psychology, 27, 41–45 | 10.1016/j.copsyc.2018.07.011
very short

Overall, there is a suggestion of two different reproductive strategies proving to be successful in modern Western societies: (1) a strategy associated with socially conservative values, including a high commitment to the bearing of children within marriage; and(2) a strategy associated with antisocial behavior, early sexual experimentation, a variety of sexual partners, low educational attainment, low commitment to marriage, haphazard pregnancies, and indifference to politics. This notion of distinct lifestyles characterized in common by relatively high fertility deserves further empirical and theoretical study.

How did the descendants of the Mayan Indians end up in the Eastern Orthodox Church?

Does Parental Quality Matter? Study using three sources of parental variation that are mostly immune to genetic confounding find that “the strong parent-child correlation in education is largely causal”. For example, “the parent-child correlation in education is stronger with the parent that spends more time with the child”.

Before and after pictures of tech leaders like Jeff Bezos, Elon Musk, and Sergey Brin suggest they’re taking supplemental testosterone. And though it may help them keep looking young, Palladium points out that there might be other effects from having some of our most powerful businessmen on a hormone that increases risk-taking and ambition. They ask whether the new availability of testosterone supplements is prolonging Silicon Valley businessmen’s “brash entrepreneur” phase well past the point where they would normally become mature respectable elders. But it also hints at an almost opposite take: average testosterone levels have been falling for decades, so at this point these businessmen would be the only “normal” (by 1950s standards) men out there, and everyone else would be unprecedently risk-averse and boring. Paging Peter Thiel and everyone else who takes about how things “just worked better” in Eisenhower’s day.

China’s SesameCredit social monitoring system, widely portrayed as dystopian, has an 80% approval rate in China (vs. 19% neutral and 1% disapproval). The researchers admit that although all data is confidential and they are not affiliated with the Chinese government, their participants might not believe that confidently enough to answer honestly.

I know how much you guys love attacking EAs for “pathological altruism” or whatever terms you’re using nowadays, so here’s an article where rationalist community member John Beshir describes his experience getting malaria on purpose to help researchers test a vaccine.

Cultural variation in cultural evolution | Proceedings of the Royal Society of London B: Biological Sciences
Cultural evolutionary models have identified a range of conditions under which social learning (copying others) is predicted to be adaptive relative to asocial learning (learning on one's own), particularly in humans where socially learned information can accumulate over successive generations. However, cultural evolution and behavioural economics experiments have consistently shown apparently maladaptive under-utilization of social information in Western populations. Here we provide experimental evidence of cultural variation in people's use of social learning, potentially explaining this mismatch. People in mainland China showed significantly more social learning than British people in an artefact-design task designed to assess the adaptiveness of social information use. People in Hong Kong, and Chinese immigrants in the UK, resembled British people in their social information use, suggesting a recent shift in these groups from social to asocial learning due to exposure to Western culture. Finally, Chinese mainland participants responded less than other participants to increased environmental change within the task. Our results suggest that learning strategies in humans are culturally variable and not genetically fixed, necessitating the study of the ‘social learning of social learning strategies' whereby the dynamics of cultural evolution are responsive to social processes, such as migration, education and globalization.

...

Western education emphasizes individual discovery and creativity, whereas East Asian education emphasizes rote learning from authority [25]. The adoption of consumer products shows less social influence in Western than East Asian countries [26]. Westerners are described as more individualistic/independent, while East Asians are described as more collectivistic/interdependent [27], dimensions which intuitively map on to asocial and social learning, respectively.

Societal background influences social learning in cooperative decision making: https://www.sciencedirect.com/science/article/pii/S1090513817303501
We demonstrate that Chinese participants base their cooperation decisions on information about their peers much more frequently than their British counterparts. Moreover, our results reveal remarkable societal differences in the type of peer information people consider. In contrast to the consensus view, Chinese participants tend to be substantially less majority-oriented than the British. While Chinese participants are inclined to adopt peer behavior that leads to higher payoffs, British participants tend to cooperate only if sufficiently many peers do so too. These results indicate that the basic processes underlying social transmission are not universal; rather, they vary with cultural conditions. As success-based learning is associated with selfish behavior and majority-based learning can help foster cooperation, our study suggests that in different societies social learning can play diverging roles in the emergence and maintenance of cooperation.

Who We Are | West Hunter
I’m going to review David Reich’s new book, Who We Are and How We Got Here. Extensively: in a sense I’ve already been doing this for a long time. Probably there will be a podcast. The GoFundMe link is here. You can also send money via Paypal (Use the donate button), or bitcoins to 1Jv4cu1wETM5Xs9unjKbDbCrRF2mrjWXr5. In-kind donations, such as orichalcum or mithril, are always appreciated.

This is the book about the application of ancient DNA to prehistory and history.

"Homo Naledi, a small-brained homonin identified from recently discovered fossils in South Africa, appears to have hung around way later that you’d expect (up to 200,000 years ago, maybe later) than would be the case if modern humans had occupied that area back then. To be blunt, we would have eaten them."

Live Not By Lies: https://westhunt.wordpress.com/2018/04/08/live-not-by-lies/
Next he slams people that suspect that upcoming genetic genetic analysis will, in most cases, confirm traditional stereotypes about race – the way the world actually looks.

The people Reich dumps on are saying perfectly reasonable things. He criticizes Henry Harpending for saying that he’d never seen an African with a hobby. Of course, Henry had actually spent time in Africa, and that’s what he’d seen. The implication is that people in Malthusian farming societies – which Africa was not – were selected to want to work, even where there was no immediate necessity to do so. Thus hobbies, something like a gerbil running in an exercise wheel.

He criticized Nicholas Wade, for saying that different races have different dispositions. Wade’s book wasn’t very good, but of course personality varies by race: Darwin certainly thought so. You can see differences at birth. Cover a baby’s nose with a cloth: Chinese and Navajo babies quietly breathe through their mouth, European and African babies fuss and fight.

Then he attacks Watson, for asking when Reich was going to look at Jewish genetics – the kind that has led to greater-than-average intelligence. Watson was undoubtedly trying to get a rise out of Reich, but it’s a perfectly reasonable question. Ashkenazi Jews are smarter than the average bear and everybody knows it. Selection is the only possible explanation, and the conditions in the Middle ages – white-collar job specialization and a high degree of endogamy, were just what the doctor ordered.

Watson’s a prick, but he’s a great prick, and what he said was correct. Henry was a prince among men, and Nick Wade is a decent guy as well. Reich is totally out of line here: he’s being a dick.

Now Reich may be trying to burnish his anti-racist credentials, which surely need some renewal after having pointing out that race as colloquially used is pretty reasonable, there’s no reason pops can’t be different, people that said otherwise ( like Lewontin, Gould, Montagu, etc. ) were lying, Aryans conquered Europe and India, while we’re tied to the train tracks with scary genetic results coming straight at us. I don’t care: he’s being a weasel, slandering the dead and abusing the obnoxious old genius who laid the foundations of his field. Reich will also get old someday: perhaps he too will someday lose track of all the nonsense he’s supposed to say, or just stop caring. Maybe he already has… I’m pretty sure that Reich does not like lying – which is why he wrote this section of the book (not at all logically necessary for his exposition of the ancient DNA work) but the required complex juggling of lies and truth required to get past the demented gatekeepers of our society may not be his forte. It has been said that if it was discovered that someone in the business was secretly an android, David Reich would be the prime suspect. No Talleyrand he.

https://westhunt.wordpress.com/2018/04/12/who-we-are-6-the-americas/
The population that accounts for the vast majority of Native American ancestry, which we will call Amerinds, came into existence somewhere in northern Asia. It was formed from a mix of Ancient North Eurasians and a population related to the Han Chinese – about 40% ANE and 60% proto-Chinese. Is looks as if most of the paternal ancestry was from the ANE, while almost all of the maternal ancestry was from the proto-Han. [Aryan-Transpacific ?!?] This formation story – ANE boys, East-end girls – is similar to the formation story for the Indo-Europeans.

https://westhunt.wordpress.com/2018/04/18/who-we-are-7-africa/
In some ways, on some questions, learning more from genetics has left us less certain. At this point we really don’t know where anatomically humans originated. Greater genetic variety in sub-Saharan African has been traditionally considered a sign that AMH originated there, but it possible that we originated elsewhere, perhaps in North Africa or the Middle East, and gained extra genetic variation when we moved into sub-Saharan Africa and mixed with various archaic groups that already existed. One consideration is that finding recent archaic admixture in a population may well be a sign that modern humans didn’t arise in that region ( like language substrates) – which makes South Africa and West Africa look less likely. The long-continued existence of homo naledi in South Africa suggests that modern humans may not have been there for all that long – if we had co-existed with homo naledi, they probably wouldn’t lasted long. The oldest known skull that is (probably) AMh was recently found in Morocco, while modern humans remains, already known from about 100,000 years ago in Israel, have recently been found in northern Saudi Arabia.

While work by Nick Patterson suggests that modern humans were formed by a fusion between two long-isolated populations, a bit less than half a million years ago.

So: genomics had made recent history Africa pretty clear. Bantu agriculuralists expanded and replaced hunter-gatherers, farmers and herders from the Middle East settled North Africa, Egypt and northeaat Africa, while Nilotic herdsmen expanded south from the Sudan. There are traces of earlier patterns and peoples, but today, only traces. As for questions back further in time, such as the origins of modern humans – we thought we knew, and now we know we don’t. But that’s progress.

https://westhunt.wordpress.com/2018/04/18/reichs-journey/
David Reich’s professional path must have shaped his perspective on the social sciences. Look at the record. He starts his professional career examining the role of genetics in the elevated prostate cancer risk seen in African-American men. Various social-science fruitcakes oppose him even looking at the question of ancestry ( African vs European). But they were wrong: certain African-origin alleles explain the increased risk. Anthropologists (and human geneticists) were sure (based on nothing) that modern humans hadn’t interbred with Neanderthals – but of course that happened. Anthropologists and archaeologists knew that Gustaf Kossina couldn’t have been right when he said that widespread material culture corresponded to widespread ethnic groups, and that migration was the primary explanation for changes in the archaeological record – but he was right. They knew that the Indo-European languages just couldn’t have been imposed by fire and sword – but Reich’s work proved them wrong. Lots of people – the usual suspects plus Hindu nationalists – were sure that the AIT ( Aryan Invasion Theory) was wrong, but it looks pretty good today.

Some sociologists believed that caste in India was somehow imposed or significantly intensified by the British – but it turns out that most jatis have been almost perfectly endogamous for two thousand years or more…

It may be that Reich doesn’t take these guys too seriously anymore. Why should he?

The massive mixture events that occurred in the recent past to give rise to Europeans and South Asians, to name just two groups, were likely “male mediated.” That’s another way of saying that men on the move took local women as brides or concubines. In the New World there are many examples of this, whether it be among African Americans, where most European ancestry seems to come through men, or in Latin America, where conquistadores famously took local women as paramours. Both of these examples are disquieting, and hint at the deep structural roots of patriarchal inequality and social subjugation that form the backdrop for the emergence of many modern peoples.

China’s Ideological Spectrum
We find that public preferences are weakly constrained, and the configuration of preferences is multidimensional, but the latent traits of these dimensions are highly correlated. Those who prefer authoritarian rule are more likely to support nationalism, state intervention in the economy, and traditional social values; those who prefer democratic institutions and values are more likely to support market reforms but less likely to be nationalistic and less likely to support traditional social values. This latter set of preferences appears more in provinces with higher levels of development and among wealthier and better-educated respondents.

Enlightened One-Party Rule? Ideological Differences between Chinese Communist Party Members and the Mass Public: https://journals.sagepub.com/doi/abs/10.1177/1065912919850342
A popular view of nondemocratic regimes is that they draw followers mainly from those with an illiberal, authoritarian mind-set. We challenge this view by arguing that there exist a different class of autocracies that rule with a relatively enlightened base. Leveraging multiple nationally representative surveys from China over the past decade, we substantiate this claim by estimating and comparing the ideological preferences of Chinese Communist Party members and ordinary citizens. We find that party members on average hold substantially more modern and progressive views than the public on issues such as gender equality, political pluralism, and openness to international exchange. We also explore two mechanisms that may account for this party–public value gap—selection and socialization. We find that while education-based selection is the most dominant mechanism overall, socialization also plays a role, especially among older and less educated party members.

The Western Elite from a Chinese Perspective - American Affairs Journal
I don’t claim to be a modern-day Alexis de Tocqueville, nor do I have much in common with this famous observer of American life. He grew up in Paris, a city renowned for its culture and architecture. I grew up in Shijiazhuang, a city renowned for being the headquarters of the company that produced toxic infant formula. He was a child of aristocrats; I am the child of modest workers.

Nevertheless, I hope my candid observations can provide some insights into the elite institutions of the West. Certain beliefs are as ubiquitous among the people I went to school with as smog was in Shijiazhuang. The doctrines that shape the worldviews and cultural assumptions at elite Western institutions like Cambridge, Stanford, and Goldman Sachs have become almost religious. Nevertheless, I hope that the perspective of a candid Chinese atheist can be of some instruction to them.

...

So I came to the UK in 2001, when I was 16 years old. Much to my surprise, I found the UK’s exam-focused educational system very similar to the one in China. What is more, in both countries, going to the “right schools” and getting the “right job” are seen as very important by a large group of eager parents. As a result, scoring well on exams and doing well in school interviews—or even the play session for the nursery or pre-prep school—become the most important things in the world. Even at the university level, the undergraduate degree from the University of Cambridge depends on nothing else but an exam at the end of the last year.

On the other hand, although the UK’s university system is considered superior to China’s, with a population that is only one-twentieth the size of my native country, competition, while tough, is less intimidating. For example, about one in ten applicants gets into Oxbridge in the UK, and Stanford and Harvard accept about one in twenty-five applicants. But in Hebei province in China, where I am from, only one in fifteen hundred applicants gets into Peking or Qinghua University.

Still, I found it hard to believe how much easier everything became. I scored first nationwide in the GCSE (high school) math exam, and my photo was printed in a national newspaper. I was admitted into Trinity College, University of Cambridge, once the home of Sir Isaac Newton, Francis Bacon, and Prince Charles.

I studied economics at Cambridge, a field which has become more and more mathematical since the 1970s. The goal is always to use a mathematical model to find a closed-form solution to a real-world problem. Looking back, I’m not sure why my professors were so focused on these models. I have since found that the mistake of blindly relying on models is quite widespread in both trading and investing—often with disastrous results, such as the infamous collapse of the hedge fund Long-Term Capital Management. Years later, I discovered the teaching of Warren Buffett: it is better to be approximately right than precisely wrong. But our professors taught us to think of the real world as a math problem.

The culture of Cambridge followed the dogmas of the classroom: a fervent adherence to rules and models established by tradition. For example, at Cambridge, students are forbidden to walk on grass. This right is reserved for professors only. The only exception is for those who achieve first class honors in exams; they are allowed to walk on one area of grass on one day of the year.

The behavior of my British classmates demonstrated an even greater herd mentality than what is often mocked in American MBAs. For example, out of the thirteen economists in my year at Trinity, twelve would go on to join investment banks, and five of us went to work for Goldman Sachs.

...

To me, Costco represents the best of American capitalism. It is a corporation known for having its customers and employees in mind, while at the same time it has compensated its shareholders handsomely over the years. To the customers, it offers the best combination of quality and low cost. Whenever it manages to reduce costs, it passes the savings on to customers immediately. Achieving a 10 percent gross margin with prices below Amazon’s is truly incredible. After I had been there once, I found it hard to shop elsewhere.

Meanwhile, its salaries are much higher than similar retail jobs. When the recession hit in 2008, the company increased salaries to help employees cope with the difficult environment. From the name tags the staff wear, I have seen that frontline employees work there for decades, something hard to imagine elsewhere.

Stanford was for me a distant second to Costco in terms of the American capitalist experience. Overall, I enjoyed the curriculum at the GSB. Inevitably I found some classes less interesting, but the professors all seemed to be quite understanding, even when they saw me reading my kindle during class.

One class was about strategy. It focused on how corporate mottos and logos could inspire employees. Many of the students had worked for nonprofits or health care or tech companies, all of which had mottos about changing the world, saving lives, saving the planet, etc. The professor seemed to like these mottos. I told him that at Goldman our motto was “be long-term greedy.” The professor couldn’t understand this motto or why it was inspiring. I explained to him that everyone else in the market was short-term greedy and, as a result, we took all their money. Since traders like money, this was inspiring. He asked if perhaps there was another motto or logo that my other classmates might connect with. I told him about the black swan I kept on my desk as a reminder that low probability events happen with high frequency. He didn’t like that motto either and decided to call on another student, who had worked at Pfizer. Their motto was “all people deserve to live healthy lives.” The professor thought this was much better. I didn’t understand how it would motivate employees, but this was exactly why I had come to Stanford: to learn the key lessons of interpersonal communication and leadership.

On the communication and leadership front, I came to the GSB knowing I was not good and hoped to get better. My favorite class was called “Interpersonal Dynamics” or, as students referred to it, “Touchy Feely.” In “Touchy Feely,” students get very candid feedback on how their words and actions affect others in a small group that meets several hours per week for a whole quarter.

We talked about microaggressions and feelings and empathy and listening. Sometimes in class the professor would say things to me like “Puzhong, when Mary said that, I could see you were really feeling something,” or “Puzhong, I could see in your eyes that Peter’s story affected you.” And I would tell them I didn’t feel anything. I was quite confused.

One of the papers we studied mentioned that subjects are often not conscious of their own feelings when fully immersed in a situation. But body indicators such as heart rate would show whether the person is experiencing strong emotions. I thought that I generally didn’t have a lot of emotions and decided that this might be a good way for me to discover my hidden emotions that the professor kept asking about.

So I bought a heart rate monitor and checked my resting heart rate. Right around 78. And when the professor said to me in class “Puzhong, I can see that story brought up some emotions in you,” I rolled up my sleeve and checked my heart rate. It was about 77. And so I said, “nope, no emotion.” The experiment seemed to confirm my prior belief: my heart rate hardly moved, even when I was criticized, though it did jump when I became excited or laughed.

This didn’t land well on some of my classmates. They felt I was not treating these matters with the seriousness that they deserved. The professor was very angry. My takeaway was that my interpersonal skills were so bad that I could easily offend people unintentionally, so I concluded that after graduation I should do something that involved as little human interaction as possible.

Therefore, I decided I needed to return to work in financial markets rather than attempting something else. I went to the career service office and told them that my primary goal after the MBA was to make money. I told them that $500,000 sounded like a good number. They were very confused, though, as they said their goal was to help me find my passion and my calling. I told them that my calling was to make money for my family. They were trying to be helpful, but in my case, their advice didn’t turn out to be very helpful.

Eventually I was able to meet the chief financial officer of my favorite company, Costco. He told me that they don’t hire any MBAs. Everyone starts by pushing trolleys. (I have seriously thought about doing just that. But my wife is strongly against it.) Maybe, I thought, that is why the company is so successful—no MBAs!

Warren Buffett has said that the moment one was born in the United States or another Western country, that person has essentially won a lottery. If someone is born a U.S. citizen, he or she enjoys a huge advantage in almost every aspect of life, including expected wealth, education, health care, environment, safety, etc., when compared to someone born in developing countries. For someone foreign to “purchase” these privileges, the price tag at the moment is $1 million dollars (the rough value of the EB-5 investment visa). Even at this price level, the demand from certain countries routinely exceeds the annual allocated quota, resulting in long waiting times. In that sense, American citizens were born millionaires!

Yet one wonders how long such luck will last. This brings me back to the title of Rubin’s book, his “uncertain world.” In such a world, the vast majority things are outside our control, determined by God or luck. After we have given our best and once the final card is drawn, we should neither become too excited by what we have achieved nor too depressed by what we failed to … [more]

Self-Serving Bias | Slate Star Codex
Since reading Tabarrok’s post, I’ve been trying to think of more examples of this sort of thing, especially in medicine. There are way too many discrepancies in approved medications between countries to discuss every one of them, but did you know melatonin is banned in most of Europe? (Europeans: did you know melatonin is sold like candy in the United States?) Did you know most European countries have no such thing as “medical school”, but just have college students major in medicine, and then become doctors once they graduate from college? (Europeans: did you know Americans have to major in some random subject in college, and then go to a separate place called “medical school” for four years to even start learning medicine?) Did you know that in Puerto Rico, you can just walk into a pharmacy and get any non-scheduled drug you want without a doctor’s prescription? (source: my father; I have never heard anyone else talk about this, and nobody else even seems to think it is interesting enough to be worth noting).

...

And then there’s the discussion from the recent discussion of Madness and Civilization about how 18th century doctors thought hot drinks will destroy masculinity and ruin society. Nothing that’s happened since has really disproved this – indeed, a graph of hot drink consumption, decline of masculinity, and ruinedness of society would probably show a pretty high correlation – it’s just somehow gotten tossed in the bin marked “ridiculous” instead of the bin marked “things we have to worry about”.

Are Sunk Costs Fallacies? - Gwern.net
But to what extent is the sunk cost fallacy a real fallacy?
Below, I argue the following:
1. sunk costs are probably issues in big organizations
- but maybe not ones that can be helped
2. sunk costs are not issues in animals
3. sunk costs appear to exist in children & adults
- but many apparent instances of the fallacy are better explained as part of a learning strategy
- and there’s little evidence sunk cost-like behavior leads to actual problems in individuals
4. much of what we call sunk cost looks like simple carelessness & thoughtlessness

The 5 Biggest Tax Credits You Might Qualify For - TurboTax Tax Tips & Videos
One of the most substantial credits for taxpayers is the Earned Income Tax Credit. Established in 1975—in part to offset the burden of Social Security taxes and to provide an incentive to work—the EITC is determined by income and is phased in according to filing status: single, married filing jointly or either of those with children. Eligibility and the amount of the credit are based on adjusted gross income, earned income and investment income.

A person must be at least 25 years old and younger than 65 to qualify. If married, both spouses must have valid Social Security numbers and must have lived in the country for more than six months. If you may be claimed as a dependent on another filer's tax return, you do not qualify.

Those "married filing separately" do not qualify for the EITC, said Louis Barajas, a Santa Fe Springs, California-based financial planner and author who serves many low-to-moderate-income families in his boutique planning firm, Louis Barajas Wealth Planning.

Red State Families: Better Than We Knew | Institute for Family Studies
Second, adjusting for education and race/ethnicity transforms the relationship between the Red State Index and marital upbringing from a curvilinear to a linear one. The redder the state, the more likely is a teen to grow up with his or her married birth parents. The relationship is modest but statistically significant. For every ten-point increase in the Red State Index, the proportion of teens living with both parents rises by one percentage point. This suggests that red state family culture is associated with increased odds of being raised in an intact, married family.

Race, Religion, and Immigration in… | Democracy Fund Voter Study Group
Figure 2 The Relationship between 2011 Attitudes and Vote Choices in 2012

Third, although perceptions of the economy are related to vote choice in both years—unsurprisingly, people who believed the economy was doing worse were more likely to vote for the out-party Republicans—its effect is similar in both years. This suggests that the 2016 vote choice was not uniquely about “economic anxiety.”

The results also show that certain factors were less strongly related to voters’ choice in 2016 than they were in 2012: social issue attitudes, economic issue attitudes, and, more notably, party identification. The smaller impact of party identification reflects the larger number of defections in 2016, as compared to 2012.

What stands out most, however, is the attitudes that became more strongly related to the vote in 2016: attitudes about immigration, feelings toward black people, and feelings toward Muslims. This pattern fits the prevailing discourse of the two campaigns and the increased attention to issues involving ethnic, racial, and religious minorities in 2016.(v)

Places, not Programs – spottedtoad
1. There has to be a place for people to go.
2. It has to be safe.
3. There preferably needs to be bathrooms and water available there.
Schools fulfill this list, which is one reason they are still among our few remaining sources of shared meaning and in-person community. As Christ Arnade has often remarked, McDonalds fast-food restaurants fulfill this list, and are therefore undervalued sources of community in low-income communities. (The young black guys in my Philadelphia Americorps program would not-entirely-jokingly allude to McDonalds as the central hub of the weekend social/dating scene, where only one’s most immaculate clothing- a brand-new shirt, purchased just for the occasion- would suffice.) Howard Schultz, for all his occasional bouts of madness, understood from the beginning that Starbucks would succeed by becoming a “third space” between work and home, which the coffee chain for all its faults has indubitably become for many people. Ivan Illich argued that the streets themselves in poor countries once, but no longer, acted as the same kind of collective commons.

Where Has Progress Got Us? - NYTimes.com
THE TRUE AND ONLY HEAVEN Progress and Its Critics. By Christopher Lasch. 591 pp. New York: W.W. Norton & Company. $25.

reviewed by William Julius Wilson

Lower-middle-class culture, Mr. Lasch argues, reflects an emphasis on the family, the church and the neighborhood. A community's continuity is valued more highly than individual advancement, social solidarity is favored over social mobility and the maintenance of existing ways takes precedent over mainstream ideals of success. Parents want their children to succeed in life, but they also want them to be considerate of their elders, to willingly bear their responsibilities and to show courage under adversity. "More concerned with honor than with worldly ambition, they have less interest in the future than do upper-middle-class parents, who try to equip their children with the qualities required for competitive advancement."

Mr. Lasch acknowledges the provincialism and narrowness of lower-middle-class culture, and he does not deny that "it has produced racism, nativism, anti-intellectualism, and all the other evils so often cited by liberal critics." But, he maintains, in their zeal to condemn such objectionable traits, liberals have failed to see the valuable features of petty-bourgeois culture -- what he calls moral realism, skepticism about progress, respect for limits and understanding that everything has its price.

The Importance of Educational Credentials: Schooling Decisions and Returns in Modern China
A key contribution of our paper is to estimate the returns to an additional year of schooling while holding highest credential constant. We find the year generates a two percent gain in monthly income, with somewhat higher returns for China’s disadvantaged. This is much smaller than most estimates which do not separate the returns to additional schooling from those to earning a credential. We show that the policy, while redistributive, has generated a likely net loss of tens of billions of dollars. We interpret these results through a model of signaling and human capital accumulation and conclude that a high signaling value of earning a credential, also known as “credentialism,” plays a crucial role in household schooling decisions and in the returns to schooling in modern China.

Access to Elite Education, Wage Premium, and Social Mobility: Evidence from China’s College Entrance Exam: http://www.fas.nus.edu.sg/ecs/events/seminar/seminar-papers/17-08-31.pdf
woah:
Exploiting a discontinuity in elite university eligibility around the cut off scores, we find elite education increases the monthly wage by around 40%. While elite education eligibility does significantly affect mobility, it does not alter the influence of parental background. We also provide suggestive evidence that the wage premium is more likely to be explained by university-related networks and signaling than that of human capital.

As traditional European conservatives were pushed Left-ward by media and academic communities on immigration and social and religious rights, the vacuum was filled by the rise of blut-und-boden far right parties all across Europe. In a Sophoclean twist of fate, the European political center and center-Left is now dying, thanks to the very person that liberals like to portray as the “new leader” of the free world.

Dealing with the Dignity Deficit: https://www.the-american-interest.com/2018/04/05/dealing-dignity-deficit/
Are the grievances tearing our societies apart at this hyper-polarized moment insurmountable? A week with some AfD voters and politicians gave me a measure of hope.

More importantly, a generous welfare state appears at best to be an inadequate solution to the problems and pathologies of checker-boarded economic dislocation. The pesky question of dignity remains: Despite what boosters of a universal basic income try to tell us, our modern sense of purpose and identity remains closely tied to what we “do” for a living. Making disempowered people more comfortable does not necessarily make them less frustrated.

...

But since when are openness, cosmopolitanism, and diversity intrinsic to a complete definition of liberalism? They make no significant appearance in any of the foundational texts of liberal political thought. They are merely the product of the demands that globalization and urbanization places upon us “anywheres”, which we in turn try to wedge into the liberal canon in order to erase any discomfort we may feel about change pulling the ideological rug out from under our feet. Historical accounts of earlier periods of urbanization are rightly dispassionate in describing people flocking to cities out of economic want. And they correctly identify the emergence of the middle class and its attendant values as the product of complex factors interacting in these new circumstances. We instead now disfigure analysis into a form or moral self-congratulation.

Social Animal House: The Economic and Academic Consequences of Fraternity Membership by Jack Mara, Lewis Davis, Stephen Schmidt :: SSRN
We exploit changes in the residential and social environment on campus to identify the economic and academic consequences of fraternity membership at a small Northeastern college. Our estimates suggest that these consequences are large, with fraternity membership lowering student GPA by approximately 0.25 points on the traditional four-point scale, but raising future income by approximately 36%, for those students whose decision about membership is affected by changes in the environment. These results suggest that fraternity membership causally produces large gains in social capital, which more than outweigh its negative effects on human capital for potential members. Alcohol-related behavior does not explain much of the effects of fraternity membership on either the human capital or social capital effects. These findings suggest that college administrators face significant trade-offs when crafting policies related to Greek life on campus.

Do High School Sports Build or Reveal Character?: http://ftp.iza.org/dp11110.pdf
We examine the extent to which participation in high school athletics has beneficial effects on future education, labor market, and health outcomes. Due to the absence of plausible instruments in observational data, we use recently developed methods that relate selection on observables with selection on unobservables to estimate bounds on the causal effect of athletics participation. We analyze these effects in the US separately for men and women using three different nationally representative longitudinal data sets that each link high school athletics participation with later-life outcomes. We do not find consistent evidence of individual benefits reported in many previous studies – once we have accounted for selection, high school athletes are no more likely to attend college, earn higher wages, or participate in the labor force. However, we do find that men (but not women) who participated in high school athletics are more likely to exercise regularly as adults. Nevertheless, athletes are no less likely to be obese.

Online Social Network Effects in Labor Markets: Evidence From Facebook's Entry into College Campuses: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3381938
My estimates imply that access to Facebook for 4 years of college causes a 2.7 percentile increase in a cohort's average earnings, relative to the earnings of other individuals born in the same year.

https://marginalrevolution.com/marginalrevolution/2019/05/might-facebook-boost-wages.html
What Clockwork_Prior said. I was a college freshman when facebook first made its appearance and so I know that facebook's entry/exit cannot be treated as a quasi-random with respect to earnings. Facebook began at harvard, then expanded to other ivy league schools + places like stanford/MIT/CMU, before expanding into a larger set of universities.

Presuming the author is using a differences-in-differences research design, the estimates would be biased as they would essentially be calculating averaging earnings difference between Elite schools and non elite schools. If the sample is just restricted to the period where schools were simply elite, the problem still exist because facebook originated at Harvard and this becomes a comparison of Harvard earnings v.s. other schools.

Accurate Genomic Prediction Of Human Height | bioRxiv
Stephen Hsu's compressed sensing application paper

We construct genomic predictors for heritable and extremely complex human quantitative traits (height, heel bone density, and educational attainment) using modern methods in high dimensional statistics (i.e., machine learning). Replication tests show that these predictors capture, respectively, ~40, 20, and 9 percent of total variance for the three traits. For example, predicted heights correlate ~0.65 with actual height; actual heights of most individuals in validation samples are within a few cm of the prediction.

Key forces behind the decline of fertility: lessons from childlessness in Rouen before the industrial revolution | Springer for Research & Development
To better understand the forces underlying fertility decisions, we look at the forerunners of fertility decline. In Rouen, France, completed fertility dropped between 1640 and 1792 from 7.4 to 4.2 children. We review possible explanations and keep only three: increases in materialism, in women’s empowerment, and in returns to education. The methodology is one of analytic narrative, bringing together descriptive evidence with a theoretical model. We accordingly propose a theory showing that we can discriminate between these explanations by looking at childlessness and its social gradient. An increase in materialism or, under certain conditions, in women’s empowerment, leads to an increase in childlessness, while an increase in the return to education leads to a decrease in childlessness. Looking at the Rouen data, childlessness was clearly on the rise, from 4% in 1640 to 10% at the end of the eighteenth century, which appears to discredit the explanation based on increasing returns to education, at least for this period.

Fertility Fall Myths: http://www.overcomingbias.com/2011/09/fertility-fall-causes.html
In the latest JEL, Tim Guinnane does a nice job debunking misconceptions about the great fertility fall associated with the industrial revolution. For example, “The decline in French fertility began in the late eighteenth century,” and fertility declines were not uniform across Europe:

Mortality decline doesn’t work as an explanation for fertility declines:

Nor do child labor laws:

Nor do new social insurance programs:

Still in the running, he thinks, are increases in urbanization, female employment, and gains to schooling:

PRRI: America’s Changing Religious Identity

America, that is, the United States of America, has long been a huge exception for the secularization model. Basically as a society develops and modernizes it becomes more secular. At least that’s the model.

...

Today everyone is talking about the Pew survey which shows the marginalization of the Anglo-Protestant America which I grew up in. This marginalization is due to secularization broadly, and non-Hispanic whites in particular. You don’t need Pew to tell you this.

...

Note: Robert Putnam’s American Grace is probably the best book which highlights the complex cultural forces which ushered in the second wave of secularization. The short answer is that the culture wars diminished Christianity in the eyes of liberals.

the causal direction in the rise of the “Nones” likely runs from political identity as a liberal or conservative to religious identity

But we show that rather than religion fading into irrelevance as the secularization thesis would suggest, intense religion—strong affiliation, very frequent practice, literalism, and evangelicalism—is persistent and, in fact, only moderate religion is on the decline in the United States.

http://coldcasechristianity.com/2017/are-young-people-really-leaving-christianity/
Some writers and Christian observers deny the flight of young people altogether, but the growing statistics should alarm us enough as Church leaders to do something about the dilemma. My hope in this post is to simply consolidate some of the research (many of the summaries are directly quoted) so you can decide for yourself. I’m going to organize the recent findings in a way that illuminates the problem:

'Christianity as default is gone': the rise of a non-Christian Europe: https://www.theguardian.com/world/2018/mar/21/christianity-non-christian-europe-young-people-survey-religion
In the UK, only 7% of young adults identify as Anglican, fewer than the 10% who categorise themselves as Catholic. Young Muslims, at 6%, are on the brink of overtaking those who consider themselves part of the country’s established church.

https://en.wikipedia.org/wiki/Postchristianity
Other scholars have disputed the global decline of Christianity, and instead hypothesized of an evolution of Christianity which allows it to not only survive, but actively expand its influence in contemporary societies.

Philip Jenkins hypothesized a "Christian Revolution" in the Southern nations, such as Africa, Asia and Latin America, where instead of facing decline, Christianity is actively expanding. The relevance of Christian teachings in the global South will allow the Christian population in these areas to continually increase, and together with the shrinking of the Western Christian population, will form a "new Christendom" in which the majority of the world's Christian population can be found in the South.[9]

What’s interesting about Haidt’s alternative interpretation of the liberal progress narrative is that he mentions two elements central to the narrative—private property and nations. And what has happened to a large extent is that as the failures of communism have become increasingly apparent many on the left—including social scientists—have shifted their activism away from opposing private property and towards other aspects, for example globalism.

But how do we know a similarly disastrous thing is not going to happen with globalism as happened with communism? What if some form of national and ethnic affiliation is a deep-seated part of human nature, and that trying to forcefully suppress it will eventually lead to a disastrous counter-reaction? What if nations don’t create conflict, but alleviate it? What if a decentralised structure is the best way for human society to function?

Evidence-based | West Hunter
The central notion of evidence-based medicine is that our understanding of human biology is imperfect. Some of the idea we come up with for treating and preventing disease are effective, but most are not, worse than useless. So we need careful, rigorous statistical studies before implementing those ideas on a wide scale. A good example of doing this the wrong way was when when doctors started recommending having babies sleep prone, which roughly doubled the incidence of sudden infant death syndrome for the next several decades.

It seems to me that our understanding of psychology, sociology, economics, political science, and education is at least as imperfect as our understanding of biomedicine.

https://westhunt.wordpress.com/2015/01/24/evidence-based/#comment-65904
“Measure twice, cut once” – can’t get much more elitist than that!

Carefully testing innovations on a small scale before widely implementing them is pretty much the opposite of what self-appointed elites have done. Are you deef or something?

https://westhunt.wordpress.com/2015/01/24/evidence-based/#comment-66035
To the extent that they diverge from accepted best practice, physicians, on average, add negative value. I’ve seen this in action, and statistical studies back it up. In other words, Gregory House is a fictional character.

Do you understand the GOP play here by the way? I'm genuinely puzzled. Is it a moral conviction? Because it can't be a vote play.
In my view it's a mix of mindless sentimentality, the donor class, and existing in an hermetically sealed ideological bubble.

Medicine as a pseudoscience | West Hunter
The idea that venesection was a good thing, or at least not so bad, on the grounds that one in a few hundred people have hemochromatosis (in Northern Europe) reminds me of the people who don’t wear a seatbelt, since it would keep them from being thrown out of their convertible into a waiting haystack, complete with nubile farmer’s daughter. Daughters. It could happen. But it’s not the way to bet.

Back in the good old days, Charles II, age 53, had a fit one Sunday evening, while fondling two of his mistresses.

Monday they bled him (cupping and scarifying) of eight ounces of blood. Followed by an antimony emetic, vitriol in peony water, purgative pills, and a clyster. Followed by another clyster after two hours. Then syrup of blackthorn, more antimony, and rock salt. Next, more laxatives, white hellebore root up the nostrils. Powdered cowslip flowers. More purgatives. Then Spanish Fly. They shaved his head and stuck blistering plasters all over it, plastered the soles of his feet with tar and pigeon-dung, then said good-night.

...

Friday. The king was worse. He tells them not to let poor Nelly starve. They try the Oriental Bezoar Stone, and more bleeding. Dies at noon.

Most people didn’t suffer this kind of problem with doctors, since they never saw one. Charles had six. Now Bach and Handel saw the same eye surgeon, John Taylor – who blinded both of them. Not everyone can put that on his resume!

You may wonder how medicine continued to exist, if it had a negative effect, on the whole. There’s always the placebo effect – at least there would be, if it existed. Any real placebo effect is very small: I’d guess exactly zero. But there is regression to the mean. You see the doctor when you’re feeling worse than average – and afterwards, if he doesn’t kill you outright, you’re likely to feel better. Which would have happened whether you’d seen him or not, but they didn’t often do RCTs back in the day – I think James Lind was the first (1747).

Back in the late 19th century, Christian Scientists did better than others when sick, because they didn’t believe in medicine. For reasons I think mistaken, because Mary Baker Eddy rejected the reality of the entire material world, but hey, it worked. Parenthetically, what triggered all that New Age nonsense in 19th century New England? Hash?

This did not change until fairly recently. Sometime in the early 20th medicine, clinical medicine, what doctors do, hit break-even. Now we can’t do without it. I wonder if there are, or will be, other examples of such a pile of crap turning (mostly) into a real science.

EconPapers: Was Civil War Surgery Effective?: http://econpapers.repec.org/paper/htrhcecon/444.htm
contra Greg Cochran:
To shed light on the subject, I analyze a data set created by Dr. Edmund Andrews, a Civil war surgeon with the 1st Illinois Light Artillery. Dr. Andrews’s data can be rendered into an observational data set on surgical intervention and recovery, with controls for wound location and severity. The data also admits instruments for the surgical decision. My analysis suggests that Civil War surgery was effective, and increased the probability of survival of the typical wounded soldier, with average treatment effect of 0.25-0.28.

Some of the progress is from formal medicine, most is from civil engineering, better nutrition ( ag science and physical chemistry), less crowded housing.

Nurses vs doctors: https://westhunt.wordpress.com/2014/10/01/nurses-vs-doctors/
Medicine, the things that doctors do, was an ineffective pseudoscience until fairly recently. Until 1800 or so, they were wrong about almost everything. Bleeding, cupping, purging, the four humors – useless. In the 1800s, some began to realize that they were wrong, and became medical nihilists that improved outcomes by doing less. Some patients themselves came to this realization, as when Civil War casualties hid from the surgeons and had better outcomes. Sometime in the early 20th century, MDs reached break-even, and became an increasingly positive influence on human health. As Lewis Thomas said, medicine is the youngest science.

Nursing, on the other hand, has always been useful. Just making sure that a patient is warm and nourished when too sick to take care of himself has helped many survive. In fact, some of the truly crushing epidemics have been greatly exacerbated when there were too few healthy people to take care of the sick.

Nursing must be old, but it can’t have existed forever. Whenever it came into existence, it must have changed the selective forces acting on the human immune system. Before nursing, being sufficiently incapacitated would have been uniformly fatal – afterwards, immune responses that involved a period of incapacitation (with eventual recovery) could have been selectively favored.

when MDs broke even: https://westhunt.wordpress.com/2014/10/01/nurses-vs-doctors/#comment-58981
I’d guess the 1930s. Lewis Thomas thought that he was living through big changes. They had a working serum therapy for lobar pneumonia ( antibody-based). They had many new vaccines ( diphtheria in 1923, whopping cough in 1926, BCG and tetanus in 1927, yellow fever in 1935, typhus in 1937.) Vitamins had been mostly worked out. Insulin was discovered in 1929. Blood transfusions. The sulfa drugs, first broad-spectrum antibiotics, showed up in 1935.

DALYs per doctor: https://westhunt.wordpress.com/2018/01/22/dalys-per-doctor/
The disability-adjusted life year (DALY) is a measure of overall disease burden – the number of years lost. I’m wondering just much harm premodern medicine did, per doctor. How many healthy years of life did a typical doctor destroy (net) in past times?

...

It looks as if the average doctor (in Western medicine) killed a bunch of people over his career ( when contrasted with doing nothing). In the Charles Manson class.

Eventually the market saw through this illusion. Only took a couple of thousand years.

For example when he talks about the paradox of blacks being more sentenced on drug offenses than whites although they use drugs at similar rate. No paradox: guys go to the big house for dealing, not for using. Where does he live – Mars?

I had the same reaction when Hanson parroted some dipshit anthropologist arguing that the stupid things people do while drunk are due to social expectations, not really the alcohol.

My impression is that while people may be “kinda dumb”, ancient customs typically aren’t.
Even if we assume that all people who lived prior to the 19th century were too dumb to make the rational observation, wouldn’t you expect this ancient practice to be subject to selective pressure?

Stolen generations | West Hunter
Someone was quoted as saying that if you adopted an Australian Aborigine kid and raised him in England, he’d do just fine. This is a standard prediction, or maybe really an assumption, of most social scientists: people are the same everywhere. Let me put it more precisely: If you adopted a random draw of such kids just after birth, and then treated them in the same way that local native kids were treated, they’d end up with the same adult IQ, on average. And the same rate of alcoholism, and so forth. Same with any other racial group, the prediction says.

But is this actually true? The same people would say that one-day-old babies from different groups ought to act the same, and that’s certainly not true.

I would think that there was a lot of adoption of Australian Aborigines going on in Australia, back in the day. What were the results?

https://westhunt.wordpress.com/2014/03/15/stolen-generations/#comment-23715
I don’t see how you could spend a lot of time on this (aboriginal education) and not see the pattern in front of you. But people do, certainly in the US as well. Here’s a fun quote: “There is no logical reason to expect that the number of minority students in gifted programs would not be proportional to their representation in the general population. ” (p. 498) Frasier 1997
Of course this never happens, never has happened, but still it’s gotta happen.

This is secondhand, but an interesting story. There was once a graduate student in anthropology at UNM who was very interested in Australian Aboriginal education. I believe that’s what he wanted to do when he got out. He did a lot of digging into the subject, including mimeographed stuff that never got published, and much against his will came to the conclusion that Aboriginals really were different from Europeans, really did have significantly lower intelligence. It drove him nuts – he actually had to be hospitalized. Dropped out of the program.

http://www.sciencedirect.com/science/article/pii/S0304387817300664
Combining recent reservation-level census data and school enrollment data from 1911 to 1932, I find that reservations that sent a larger share of students to off-reservation boarding schools have higher high school graduation rates, higher per capita income, lower poverty rates, a greater proportion of exclusively English speakers, and smaller family sizes. These results are supported when distance to the nearest off-reservation boarding school that subsequently closed is used as an instrument for the proportion of past boarding school students. I conclude with a discussion of the possible reasons for this link.

...

Last, the link drawn here between higher boarding school share and assimilation should not be misinterpreted as an endorsement of coercive assimilation.

Hitler made the most creative use of it by playing down victimization and representing every Aryan as a superior type of person. It took the world in arms to get rid of him. But before long, revolutionaries discovered that a revolution based on the proletarian tribe only really worked if you were dealing with pretty unsophisticated peoples—preferably non-Europeans who lacked all experience of freedom and genuine political life. In socially mobile European states, the workers mostly found better things to do with their time than waste it on revolutionary committees and the baby talk of political demonstrations. Something new was needed.

It was provided by such socialists as Mussolini and Lenin who adopted the principle of the Praetorian Guard: a tightly knit vanguard party, which could use the masses as ventriloquial dummies and seek power on its own terms. This development was part of _a wider tendency towards the emergence of oligarchies ruling through democratic slogans_.

...

In the course of the 1960s, a new tribe was established that also sought to overthrow the Western citadel from within and had notably greater success. This was Betty Friedan’s radical feminists. It was a tribe constructed out of women who had taken some sort of degree and were living domestic lives. Technology had largely liberated them from the rigors of beating, sweeping, and cleaning, while pharmacology had released them from excessive procreation. In tactical terms, radical feminists made one innovation that has turned out to be crucial to the destiny of the West over the last half century. They suppressed almost completely the idea that their project involved a transfer of power and operated entirely on the moralistic principle that their demands corresponded to justice.

What lay behind this momentous development? It is a complicated question, but I think that Diana Schaub understood the essence of it in her essay “On the Character of Generation X”: 1

[Betty] Friedan was right that the malaise these privileged women were experiencing was a result of “a slow death of the mind and spirit.” _But she was wrong in saying that the problem had no name—its name was boredom._ Feminism was born of boredom, not oppression. And what was the solution to this quandary? Feminists clamored to become wage-slaves; they resolutely fled the challenge of leisure.

...

The most obvious fact about it is one that we can hardly mention, now that the revolution has succeeded, without embarrassment or derision, because it is a fact which powerful contemporary forces make recessive. It is simply that this civilization is, in the crude terms of creative hits, the achievement of white males. The history of Western civilization is a succession of clever men developing the set of traditions or inventing the benefits which, intertwined, constitute the West. And from Thales and Euclid to Einstein and George Gershwin, nearly all of them were male. They constitute the set of “dead white males” whom the radical revolutionaries in the sub-academic culture have denigrated and vowed to remove from their pedestals. I once heard a feminist put it this way: “There’s no such thing as a great mind.” This doctrine is so powerful that the simple factual statement that it has been men who have created what is commonly meant by Western (and for that matter, any other) civilization seems like an insensitive affront to the equality of mankind. And the next step in my argument must be to deal with this as a problem.

...

_The key to modern Western civilization is its openness to talent wherever found._ The feminist demand for collective quotas has overturned this basic feature of our civilization. The crucial point is that the character of a civilization is revealed by its understanding of achievement. European civilization responded to achievement wherever it could be found. To replace achievement by quota entitlements is to destroy one civilization from within and to replace it with another. We are no longer what we were. The problem is to explain how the West collapsed.

...

This example not only illuminates the success of radical feminism, but also reveals something of the long-term significance of these massive shifts of power. For the real threat to universities came not from students but from government. Students were a minor irritant in academic life, but governments were now bent on destroying the autonomy of the institutions of civil society. Students merely functioned as their fifth column. They had the effect of forcing universities even more into a public domain. Students wanted the academic to become the political and that was the effect they had. _Before 1960 universities largely ran their own affairs. By the beginning of the twenty-first century, they had all succumbed to the state subsidies that destroyed their autonomy._

...

In a few significant areas, however, no such demands are made. These areas are either where women graduates have no wish to go (rough outdoor work) or where lack of ability could lead to instant disaster, such as brain surgery or piloting commercial aircraft. Women are to be found in both, but only on the basis of ability. Universities are obviously a soft touch because the consequences of educational betrayal take decades to emerge. The effect of university quotas for “gender diversity” for example has often been to fill humanities departments with women in order to equalize numbers “distorted” (one might say) by technology and the hard sciences where even passably able women are hard to come by. Many women in the humanities departments are indeed very able, but many are not, and they have often prospered by setting up fanciful ideological courses (especially in women’s studies), _which can hardly pretend to be academic at all_.

What however of areas where women are patently unsuited—such as the army, the police force, or fire fighting? They have in fact all been under attack because although women are unsuited to the rough work at the bottom, these areas have enviable managerial opportunities higher up. They are _one more irresistible gravy train_. The fire-fighting case was dramatized by the New York judicial decision that a test of fitness for the force that nearly all women failed must be discriminatory, and therefore illegal, an extension of the idea of “the rule of law” far beyond any serious meaning. This was the doctrine called “disparate impact.” Similar considerations have affected women in the armed forces. Standards of entry have been lowered in order that women may qualify. One argument for so doing is that the rejected tests looked for qualities only rarely needed in the field, and that may indeed be true. Yet, the idea that soldiers are heroic figures doing something that women generally cannot do has forever been part of the self-understanding of men, even those who have never heard a shot fired in anger. A small boy inclined to cry out at the sting of iodine or the prick of an injection might be told “be a soldier.” Today according to the feminist doctrine he is more likely to be told to express his feelings.

The assault of women on areas such as the church raises similar issues. In principle there is not the slightest reason why women should not take on a priestly role, and one might indeed suspect that feminists may be right in diagnosing resistance in part to an unhealthy attitude to women on the part of some of the clergy. In a pastoral role, women might well be better than men, as some women are in politics. The problem is that women priests raise very awkward questions of Christian theology. Jesus selected only male disciples. Was the son of God then merely a creature of his own culture? Here most conspicuously the entry of women changes entirely the conception of the activity and not for the better. Female clergy have done little to reverse the current decline of the church. Indeed while women as individuals have often enhanced what they have joined, _the entry of women in general has seldom done much for any area previously dominated by men—except, significantly, bureaucracy_.

...

Let us now return to the teasing question of _why the male custodians of our civilization sold the pass_. Some element of _cowardice_ must certainly be recognized, because the radicals were tribal warriors making ferocious faces and stamping their feet. The defenders were white, male, and middle class, and the radicals had long been engaged in a campaign to erode the morale of each of these abstract categories. They denoted racism, sexism, and elitism respectively. Caricatured in terms of these abstractions, men found it difficult not to be written off as oppressors of women. Again, _the defenders were not united_. Many had been longstanding advocates of liberal feminism and from confusion believed that radical feminism was _merely a rather hysterical version of classical liberalism_. Retreat is a notoriously difficult maneuver to control. Each concession could be used to demand further concessions in the name of consistency. Hence the appearance in all English-speaking countries of legislation mandating equal opportunities—and who could possibly be against that? Before long, the movement had taken over the universities, many public bodies, industrial firms and, above all, the media. _Quite rapidly, hiring for status-giving jobs requiring degrees had become closely circumscribed by a set of rules. The dogma was that 50 percent of all jobs belonged to women, though the reality of quotas was long denied._

There are, of course, deeper currents. One of them is that men tended to react to radical feminism with a high-minded feeling that nothing but justice, a notoriously fluid idea, should determine public policy. _The balancing of … [more]

Is the economy illegible? | askblog
In the model of the economy as a GDP factory, the most fundamental equation is the production function, Y = f(K,L).

This says that total output (Y) is determined by the total amount of capital (K) and the total amount of labor (L).

Let me stipulate that the economy is legible to the extent that this model can be applied usefully to explain economic developments. I want to point out that the economy, while never as legible as economists might have thought, is rapidly becoming less legible.

The Determinants of Trust
Both individual experiences and community characteristics influence how much people trust each other. Using data drawn from US localities we find that the strongest factors that reduce trust are: i) a recent history of traumatic experiences, even though the passage of time reduces this effect fairly rapidly; ii) belonging to a group that historically felt discriminated against, such as minorities (black in particular) and, to a lesser extent, women; iii) being economically unsuccessful in terms of income and education; iv) living in a racially mixed community and/or in one with a high degree of income disparity. Religious beliefs and ethnic origins do not significantly affect trust. The latter result may be an indication that the American melting pot at least up to a point works, in terms of homogenizing attitudes of different cultures, even though racial cleavages leading to low trust are still quite high.

Understanding Trust: http://www.nber.org/papers/w13387
In this paper we resolve this puzzle by recognizing that trust has two components: a belief-based one and a preference based one. While the sender's behavior reflects both, we show that WVS-like measures capture mostly the belief-based component, while questions on past trusting behavior are better at capturing the preference component of trust.

MEASURING TRUST: http://scholar.harvard.edu/files/laibson/files/measuring_trust.pdf
We combine two experiments and a survey to measure trust and trustworthiness— two key components of social capital. Standard attitudinal survey questions about trust predict trustworthy behavior in our experiments much better than they predict trusting behavior. Trusting behavior in the experiments is predicted by past trusting behavior outside of the experiments. When individuals are closer socially, both trust and trustworthiness rise. Trustworthiness declines when partners are of different races or nationalities. High status individuals are able to elicit more trustworthiness in others.

What is Social Capital? The Determinants of Trust and Trustworthiness: http://www.nber.org/papers/w7216
Using a sample of Harvard undergraduates, we analyze trust and social capital in two experiments. Trusting behavior and trustworthiness rise with social connection; differences in race and nationality reduce the level of trustworthiness. Certain individuals appear to be persistently more trusting, but these people do not say they are more trusting in surveys. Survey questions about trust predict trustworthiness not trust. Only children are less trustworthy. People behave in a more trustworthy manner towards higher status individuals, and therefore status increases earnings in the experiment. As such, high status persons can be said to have more social capital.

Trust and Cheating: http://www.nber.org/papers/w18509
We find that: i) both parties to a trust exchange have implicit notions of what constitutes cheating even in a context without promises or messages; ii) these notions are not unique - the vast majority of senders would feel cheated by a negative return on their trust/investment, whereas a sizable minority defines cheating according to an equal split rule; iii) these implicit notions affect the behavior of both sides to the exchange in terms of whether to trust or cheat and to what extent. Finally, we show that individual's notions of what constitutes cheating can be traced back to two classes of values instilled by parents: cooperative and competitive. The first class of values tends to soften the notion while the other tightens it.

Nationalism and Ethnic-Based Trust: Evidence from an African Border Region: https://u.osu.edu/robinson.1012/files/2015/12/Robinson_NationalismTrust-1q3q9u1.pdf
These results offer microlevel evidence that a strong and salient national identity can diminish ethnic barriers to trust in diverse societies.

One Team, One Nation: Football, Ethnic Identity, and Conflict in Africa: http://conference.nber.org/confer//2017/SI2017/DEV/Durante_Depetris-Chauvin.pdf
Do collective experiences that prime sentiments of national unity reduce interethnic tensions and conflict? We examine this question by looking at the impact of national football teams’ victories in sub-Saharan Africa. Combining individual survey data with information on over 70 official matches played between 2000 and 2015, we find that individuals interviewed in the days after a victory of their country’s national team are less likely to report a strong sense of ethnic identity and more likely to trust people of other ethnicities than those interviewed just before. The effect is sizable and robust and is not explained by generic euphoria or optimism. Crucially, national victories do not only affect attitudes but also reduce violence. Indeed, using plausibly exogenous variation from close qualifications to the Africa Cup of Nations, we find that countries that (barely) qualified experience significantly less conflict in the following six months than countries that (barely) did not. Our findings indicate that, even where ethnic tensions have deep historical roots, patriotic shocks can reduce inter-ethnic tensions and have a tangible impact on conflict.

Why Does Ethnic Diversity Undermine Public Goods Provision?: http://www.columbia.edu/~mh2245/papers1/HHPW.pdf
We identify three families of mechanisms that link diversity to public goods provision—–what we term “preferences,” “technology,” and “strategy selection” mechanisms—–and run a series of experimental games that permit us to compare the explanatory power of distinct mechanisms within each of these three families. Results from games conducted with a random sample of 300 subjects from a slum neighborhood of Kampala, Uganda, suggest that successful public goods provision in homogenous ethnic communities can be attributed to a strategy selection mechanism: in similar settings, co-ethnics play cooperative equilibria, whereas non-co-ethnics do not. In addition, we find evidence for a technology mechanism: co-ethnics are more closely linked on social networks and thus plausibly better able to support cooperation through the threat of social sanction. We find no evidence for prominent preference mechanisms that emphasize the commonality of tastes within ethnic groups or a greater degree of altruism toward co-ethnics, and only weak evidence for technology mechanisms that focus on the impact of shared ethnicity on the productivity of teams.

does it generalize to first world?

Higher Intelligence Groups Have Higher Cooperation Rates in the Repeated Prisoner's Dilemma: https://ideas.repec.org/p/iza/izadps/dp8499.html
The initial cooperation rates are similar, it increases in the groups with higher intelligence to reach almost full cooperation, while declining in the groups with lower intelligence. The difference is produced by the cumulation of small but persistent differences in the response to past cooperation of the partner. In higher intelligence subjects, cooperation after the initial stages is immediate and becomes the default mode, defection instead requires more time. For lower intelligence groups this difference is absent. Cooperation of higher intelligence subjects is payoff sensitive, thus not automatic: in a treatment with lower continuation probability there is no difference between different intelligence groups

Why societies cooperate: https://voxeu.org/article/why-societies-cooperate
Three attributes are often suggested to generate cooperative behaviour – a good heart, good norms, and intelligence. This column reports the results of a laboratory experiment in which groups of players benefited from learning to cooperate. It finds overwhelming support for the idea that intelligence is the primary condition for a socially cohesive, cooperative society. Warm feelings towards others and good norms have only a small and transitory effect.

individual payoff, etc.:

Trust, Values and False Consensus: http://www.nber.org/papers/w18460
Trust beliefs are heterogeneous across individuals and, at the same time, persistent across generations. We investigate one mechanism yielding these dual patterns: false consensus. In the context of a trust game experiment, we show that individuals extrapolate from their own type when forming trust beliefs about the same pool of potential partners - i.e., more (less) trustworthy individuals form more optimistic (pessimistic) trust beliefs - and that this tendency continues to color trust beliefs after several rounds of game-play. Moreover, we show that one's own type/trustworthiness can be traced back to the values parents transmit to their children during their upbringing. In a second closely-related experiment, we show the economic impact of mis-calibrated trust beliefs stemming from false consensus. Miscalibrated beliefs lower participants' experimental trust game earnings by about 20 percent on average.

The Right Amount of Trust: http://www.nber.org/papers/w15344
We investigate the relationship between individual trust and individual economic performance. We find that individual income is hump-shaped in a measure of intensity of trust beliefs. Our interpretation is that highly trusting individuals tend to assume too much social risk and to be cheated more often, ultimately performing less well than those with a belief close to the mean trustworthiness of the population. On the other hand, individuals with overly pessimistic beliefs avoid being cheated, but give up profitable opportunities, therefore underperforming. The cost of either too much or too little trust is comparable to the income lost by forgoing college.

...

This framework allows us to show that income-maximizing trust typically exceeds the trust level of the average person as well as to estimate the distribution of income lost to trust mistakes. We find that although a majority of individuals has well calibrated beliefs, a non-trivial proportion of the population (10%) has trust beliefs sufficiently poorly calibrated to lower income by more than 13%.

THE GROWING IMPORTANCE OF SOCIAL SKILLS IN THE LABOR MARKET*
key fact: cognitive ability is not growing in importance, but non-cognitive ability is

The labor market increasingly rewards social skills. Between 1980 and 2012, jobs requiring high levels of social interaction grew by nearly 12 percentage points as a share of the U.S. labor force. Math-intensive but less social jobs—including many STEM occupations—shrank by 3.3 percentage points over the same period. Employment and wage growth was particularly strong for jobs requiring high levels of both math skill and social skill. To understand these patterns, I develop a model of team production where workers “trade tasks” to exploit their comparative advantage. In the model, social skills reduce coordination costs, allowing workers to specialize and work together more efficiently. The model generates predictions about sorting and the relative returns to skill across occupations, which I investigate using data from the NLSY79 and the NLSY97. Using a comparable set of skill measures and covariates across survey waves, I find that the labor market return to social skills was much greater in the 2000s than in the mid 1980s and 1990s.

g-reliant skills seem most susceptible to automation: https://fredrikdeboer.com/2017/06/14/g-reliant-skills-seem-most-susceptible-to-automation/

THE ERROR TERM: https://spottedtoad.wordpress.com/2018/02/19/the-error-term/
Imagine an objective function- something you want to maximize or minimize- with both a deterministic and a random component.

...

Part of y is rules-based and rational, part is random and outside rational control. Obviously, the ascent of civilization has, to the extent it has taken place, been based on focusing energies on those parts of the world that are responsive to rational interpretation and control.

But an interesting thing happens once automated processes are able to take over the mapping of patterns onto rules. The portion of the world that is responsive to algorithmic interpretation is also the rational, rules-based portion, almost tautologically. But in terms of our actual objective functions- the real portions of the world that we are trying to affect or influence- subtracting out the portion susceptible to algorithms does not eliminate the variation or make it unimportant. It simply makes it much more purely random rather than only partially so.

The interesting thing, to me, is that economic returns accumulate to the random portion of variation just as to the deterministic portion. In fact, if everybody has access to the same algorithms, the returns may well be largely to the random portion. The efficient market hypothesis in action, more or less.

...

But more generally, as more and more of the society comes under algorithmic control, as various forms of automated intelligence become ubiquitous, the remaining portion, and the portion for which individual workers are rewarded, might well become more irrational, more random, less satisfying, less intelligent.
