Intelligence predicts cooperativeness better than conscientiousness does - Marginal REVOLUTION
Intelligence has a large and positive long-run effect on cooperative behavior. The effect is strong when at the equilibrium of the repeated game there is a trade-off between short-run gains and long-run losses. Conscientiousness and Agreeableness have a natural, significant but transitory effect on cooperation rates

--

Note that agreeable people do cooperate more at first, but they don’t have the strategic ability and consistency of the higher IQ individuals in these games. Conscientiousness has multiple features, one of which is caution, and that deters cooperation, since the cautious are afraid of being taken advantage of. So, at least in these settings, high IQ really is the better predictor of cooperativeness, especially over longer-term horizons.

I think Garett Jones commented on this on Twitter or in a podcast?

http://www.unz.com/jthompson/prisoners-of-intelligence/
The researchers then deliberately paired up an above average intelligence player with one who was below average to see what happened. The overall return to the participants fell, because lower ability players tended to defect so as to obtain an immediate advantage, at great cost to the other player. How should the bright player respond? Simply continuing to try to cooperate does not work, because the duller player is then rewarded for his lack of cooperation. Instead, the “tit for tat” punishment strategy is required. Start by cooperating, and on the next round do whatever the other person did: if they cooperated, you cooperate; if they defected, you defect. The researchers call this “tough love”.

Four applications of retaliation were, on average, required to teach the lesson that lack of cooperation would be punished with reciprocal lack of cooperation. Eventually cooperation is established between bright and dull, but at an initial cost. Lower intelligence players learn to cooperate, because higher intelligence players punish them if they don’t. In societies where cooperation is already low, lenient and forgiving strategies become less frequent. There is very probably a level at which trust can be assumed, but below that punishment will be the norm. Where is the social tipping point below which cooperation is too costly a strategy? At what point do civil societies collapse and turn into uncivil bands?

Solow predicts that if 2 countries have the same TFP, then the poorer nation should grow faster. But poorer India grows more slowly than China.

Solow thinking leads one to suspect India has substantially lower TFP.

Recent growth is great news, but alas 5 years isn't the long run!

FWIW under Solow conditional convergence assumptions--historically robust--the fact that a country as poor as India grows only a few % faster than the world average is a sign they'll end up poorer than S Europe.

A cross-country empirical test of cognitive abilities and innovation nexus - Munich Personal RePEc Archive
In this study we analyze the relationship between national cognitive abilities and innovational output using data from 124 countries of the world. By employing cross-country IQ scores traditionally used by psychological literature to represent national intelligence, and Economic Complexity Index as a novel measure of innovation, our study shows that there is a positive connection between them. We use a variety of tests to check the robustness of the nexus. Overall, our findings indicate that more intelligent nations export more sophisticated and diverse products to the world market and thus are more innovative. Therefore, developing countries should consider investing in human capital and related institutions if they are to boost innovative capabilities and move up the technology ladder in producing and exporting sophisticated and varied lines of products. This should bring them greater economic diversity which could be a right lever in mitigating negative external shocks.

Africa is urbanising without globalising: https://capx.co/africa-is-urbanising-without-globalising/
What most African cities get by on is money from natural resources. As the Brookings Institution explains here, African cities are built for consuming, not creating, wealth. The elite who capture oil or mining revenues have to live somewhere – and they concentrate their spending in cities. That is why the nightlife and restaurant scene in Kinshasa is so good, even though nothing else works. It’s the main thing the city produces. The poor flock in, hoping to feed on the scraps. Extreme inequality isn’t so much a product of the system; it is the cause of it.

Why Africa’s development model puzzles economists: https://www.economist.com/news/finance-and-economics/21726697-structural-transformation-its-economies-not-following-precedents-why

So many African countries are poor because they lack freedom, property rights, markets, and the rule of law.

People are laughing at this but it's true. Trouble is property rights and rule of law are much easier said than done.

Did Nations that Boosted Education Grow Faster?: http://econlog.econlib.org/archives/2012/10/did_nations_tha.html
On average, no relationship. The trendline points down slightly, but for the time being let's just call it a draw. It's a well-known fact that countries that started the 1960's with high education levels grew faster (example), but this graph is about something different. This graph shows that countries that increased their education levels did not grow faster.

The Case Against Education: What's Taking So Long, Bryan Caplan: http://econlog.econlib.org/archives/2015/03/the_case_agains_9.html

Students don't seem to be getting much out of higher education.
- Bryan Caplan

College: Capital or Signal?: http://www.economicmanblog.com/2017/02/25/college-capital-or-signal/
After his review of the literature, Caplan concludes that roughly 80% of the earnings effect from college comes from signalling, with only 20% the result of skill building. Put this together with his earlier observations about the private returns to college education, along with its exploding cost, and Caplan thinks that the social returns are negative. The policy implications of this will come as very bitter medicine for friends of Bernie Sanders.

https://spottedtoad.wordpress.com/2018/02/12/the-case-against-education/
Most American public school kids are low-income; about half are non-white; most are fairly low skilled academically. For most American kids, the majority of the waking hours they spend not engaged with electronic media are at school; the majority of their in-person relationships are at school; the most important relationships they have with an adult who is not their parent is with their teacher. For their parents, the most important in-person source of community is also their kids’ school. Young people need adult mirrors, models, mentors, and in an earlier era these might have been provided by extended families, but in our own era this all falls upon schools.

Caplan gestures towards work and earlier labor force participation as alternatives to school for many if not all kids. And I empathize: the years that I would point to as making me who I am were ones where I was working, not studying. But they were years spent working in schools, as a teacher or assistant. If schools did not exist, is there an alternative that we genuinely believe would arise to draw young people into the life of their community?

...

It is not an accident that the state that spends the least on education is Utah, where the LDS church can take up some of the slack for schools, while next door Wyoming spends almost the most of any state at $16,000 per student. Education is now the one surviving binding principle of the society as a whole, the one black box everyone will agree to, and so while you can press for less subsidization of education by government, and for privatization of costs, as Caplan does, there’s really nothing people can substitute for it. This is partially about signaling, sure, but it’s also because outside of schools and a few religious enclaves our society is but a darkling plain beset by winds.

This doesn’t mean that we should leave Caplan’s critique on the shelf. Much of education is focused on an insane, zero-sum race for finite rewards. Much of schooling does push kids, parents, schools, and school systems towards a solution ad absurdum, where anything less than 100 percent of kids headed to a doctorate and the big coding job in the sky is a sign of failure of everyone concerned.

But let’s approach this with an eye towards the limits of the possible and the reality of diminishing returns.

The real reason the left would support Moander: the usual reason. because he’s an enemy.

https://westhunt.wordpress.com/2018/02/01/bright-college-days-part-i/
I have a problem in thinking about education, since my preferences and personal educational experience are atypical, so I can’t just gut it out. On the other hand, knowing that puts me ahead of a lot of people that seem convinced that all real people, including all Arab cabdrivers, think and feel just as they do.

One important fact, relevant to this review. I don’t like Caplan. I think he doesn’t understand – can’t understand – human nature, and although that sometimes confers a different and interesting perspective, it’s not a royal road to truth. Nor would I want to share a foxhole with him: I don’t trust him. So if I say that I agree with some parts of this book, you should believe me.

...

Caplan doesn’t talk about possible ways of improving knowledge acquisition and retention. Maybe he thinks that’s impossible, and he may be right, at least within a conventional universe of possibilities. That’s a bit outside of his thesis, anyhow. Me it interests.

He dismisses objections from educational psychologists who claim that studying a subject improves you in subtle ways even after you forget all of it. I too find that hard to believe. On the other hand, it looks to me as if poorly-digested fragments of information picked up in college have some effect on public policy later in life: it is no coincidence that most prominent people in public life (at a given moment) share a lot of the same ideas. People are vaguely remembering the same crap from the same sources, or related sources. It’s correlated crap, which has a much stronger effect than random crap.

These widespread new ideas are usually wrong. They come from somewhere – in part, from higher education. Along this line, Caplan thinks that college has only a weak ideological effect on students. I don’t believe he is correct. In part, this is because most people use a shifting standard: what’s liberal or conservative gets redefined over time. At any given time a population is roughly half left and half right – but the content of those labels changes a lot. There’s a shift.

I put it this way, a while ago: “When you think about it, falsehoods, stupid crap, make the best group identifiers, because anyone might agree with you when you’re obviously right. Signing up to clear nonsense is a better test of group loyalty. A true friend is with you when you’re wrong. Ideally, not just wrong, but barking mad, rolling around in your own vomit wrong.”

We will profess them in this place of wrath and tears until the extraordinary event referenced above, for which men and women have hoped and prayed for nearly 2,000 years, comes to pass.

https://westhunt.wordpress.com/2018/02/05/bright-college-days-part-ii/
According to Caplan, employers are looking for conformity, conscientiousness, and intelligence. They use completion of high school, or completion of college as a sign of conformity and conscientiousness. College certainly looks as if it’s mostly signaling, and it’s hugely expensive signaling, in terms of college costs and foregone earnings.

But inserting conformity into the merit function is tricky: things become important signals… because they’re important signals. Otherwise useful actions are contraindicated because they’re “not done”. For example, test scores convey useful information. They could help show that an applicant is smart even though he attended a mediocre school – the same role they play in college admissions. But employers seldom request test scores, and although applicants may provide them, few do. Caplan says ” The word on the street… [more]

Is America smart enough? A Q&A with Garett Jones on IQ and the 'Hive Mind' - AEI | Pethokoukis Blog » AEIdeas
hmmm, shit:
Well, if we’re looking at the very recent trends over the last couple of decades, there is not much evidence that there’s been a bigger return to IQ than there used to be. I think there’s moderate evidence that there’s actually an increase in return to personality-type skills.

evidence: https://pinboard.in/u:nhaliday/b:d70bdc68a51c

One of my colleagues one said offhand a line that I think others have said, which is that 90% of success is staying off the Internet. And I think there’s something to this idea that the return to personality-type measures is probably a lot higher than it used to be. Agreeableness, conscientiousness, especially in certain settings. I’ve looked at the normal statistical results and they don’t find an increase in return to IQ in recent decades. But there’s a couple of studies out there that do find an increase in returns to what they call non-cognitive skills.

I think personality might be mattering more. If the robots are going to take some jobs, they’ll probably be taking a lot of brainy type jobs. But they’re going to be a little behind the times when it comes to personality. And a lot of in-person services are going to depend on personality traits.

more:
So Google and its many spinoffs replace a lot of the need for crystallized intelligence. But the need for fluid intelligence is going to be with us for quite some time. The ability to look at a new, novel situation and figure out what’s going on here.

Some pro-IQ supporters, especially on the Internet, tend to think that there’s this some kind of cutoff where above a certain level IQ matters a lot. Below it, it doesn’t matter very much. And I just don’t find evidence of that. I think that there’s a reason why the market pays for IQ, for higher IQ across the range of the scores. It’s because it’s always good to have somebody around who can just look at an ambiguous situation and figure out what’s going on.

another neat comment:
I think the obsession with years of education really needs to end. And there should be an obsession with broad based test scores. If people don’t want to use IQ scores, that’s fine. But they should at least be looking at broad based test scores, things like the NAEPs, other test scores that the US government is quite happy to report on the Department of Education’s website. These should be the measures we look at. We should be looking a lot less at years of education.

Does culture cultivate, or do you need a good plough? - The Unz Review
Each subtest’s proportion of variance in IQ shared with general intelligence was a function of cultural load: The more culture loaded, the higher this proportion. In addition, in adult samples, culture-loaded tests tended to have greater heritability coefficients than did culture-reduced tests, and there was a relationship between subtest’s proportion of variance shared with general intelligence and heritability. In child samples, these relationships were in the same direction, but correlations were small and insignificant.

What do IQ researchers really think about the Flynn Effect? - The Unz Review
Poor countries are predicted to keep raising their game, and their intellects, richer countries less so. The USA is the only country predicted to decline in ability, presumably because of mass migration. The real experts take an even more jaundiced view, and hold out little hope for The West. These predictions will be partly testable within one generation, so pin this table to your study notice board, and test for goodness of fit in 2040.

Determinants and Consequences of Bureaucrat Effectiveness: Evidence from the Indian Administrative Service∗
- not sure what he meant by Rindermann-Thompsonish: https://twitter.com/pseudoerasmus/status/672752859960745984
- edit: actually I think he's referring to the "intelligence of govt" stuff

Do bureaucrats matter? This paper studies high ranking bureaucrats in India to examine what determines their effectiveness and whether effectiveness affects state-level outcomes. Combining rich administrative data from the Indian Administrative Service (IAS) with a unique stakeholder survey on the effectiveness of IAS officers, we (i) document correlates of individual bureaucrat effectiveness, (ii) identify the extent to which rigid seniority-based promotion and exit rules affect effectiveness, and (iii) quantify the impact of this rigidity on state-level performance. Our empirical strategy exploits variation in cohort sizes and age at entry induced by the rule-based assignment of IAS officers across states as a source of differential promotion incentives.

"Thus, all countries except the most patient have negative net worth and negative holdings of net foreign assets: the most patient country holds title to all capital flows from the less patient. Consumption per unit of effective labor approaches zero (kept from zero consumption only by the Inada condition) because income flows are devoted to debt repayment. Indeed, in steady state all but the most patient country have savings rates near 100%—but these savings are mere debt repayments to the most patient country. In this steady state, the most patient country (or more realistically, countries) would continue to consume a non-negligible amount and would have the lowest savings rate(s) in the world."

Michigan leads the nation in routing around democracy. The pessimistic view is that democracy shouldn’t be routed around.

Chanda Chisala at Unz Report is on a roll. He’s been talking a lot about how the success of African immigrants to the US confounds a lot of simplistic explanations of the black-white achievement gap. Everybody figured this was just a result of those immigrants being heavily selected, but now he’s back with two posts arguing that it’s not selection effects. First, he points out that the immigrants’ children don’t seem to be regressing to the mean in a very specific Jensenian way that we would expect if they had been selected – this is more complex than I originally thought and not answered simply by “the offspring of two equally extreme parents will not regress”. Second, he points out that even the children of Somali refugees – an unselected population if ever there was one – seem to be doing better than native-born African-Americans. Some attempts at counterargument from James Thompson and Human Varieties. It’s good to see these issues being debated by such civil and mathematically sophisticated people, and also a sign of change how many people on both sides are black. Also by Chisala: book about Barack Obama debating Ayn Rand

Very large randomized controlled preschool study finds abysmal results of pre-K education; recipients of pre-K do better in kindergarten, but by third grade the trend reverses and they have worse behavioral and academic outcomes (hey, remember that study from last month how entering school too early may exacerbate ADHD)? This echoes results from the last few large randomized well-conducted preschool studies, so even the educational establishment is vaguely starting to notice a trend. James Heckman leads the pro-pre-K response, saying that past studies have found the same lack of advantage in later school performance but then later found better adult employment and prosociality outcomes; his explanation is that preschool doesn’t necessarily increase IQ but does increase “social and emotional skills that are greater determinants of late-life success”. But then how come the pre-K children had worse behavior in school in the new study? Possible explanation: the old studies Heckman cites were preschool plus a bunch of early life care and parenting help; maybe the latter helped and the former was at best neutral? Vox has a really excellent summary.
