Human Biodiversity, Psychometrics, and Evolutionary Psychology

That ancient question - what accounts for the wealth of nations? Don't tax yourself with Adam Smith or Landes. It's mostly intelligence, with a small dash of social cohesion.

Health Inequalities: Why do Latinos Live Longer than Whites?

Is summarized below for each state (source) – and it shows some very interesting patterns. The average life expectancy of Asian-Americans (86.5 years) is 4 years higher than in Japan – the longest-lived big East Asian country. Taiwan and South Korea are at around 80; Hong Kong is at 83; Singapore is at 81. The […]

The Racists Aren’t Where the Prof Said They’d Be

A few months late, but worth posting anyway. The results are based on the latest “wave” of the World Values Survey, a very interesting project that tracks sociological data across countries – and which I will likely post more about in the future. Interesting observations: (1) The West in general is the world’s least “racist”* […]

Only 15% of Scandinavian Pupils can do Basic Fractions

Further to my post on the remarkable failure of Scandinavian education systems to develop their students to anywhere near the levels indicated by their IQ potentials, a professor of mathematics at a Wisconsin university sent me data on the percentage of respondents in the TIMSS who gave the correct answer to the following question: Which […]

Preliminary Thoughts on TIMSS/PIRLS 2012

I had been meaning to post about this for a long time. Better late than never, I suppose. The TIMSS and PIRLS are international assessments of academic ability in math, science and literacy that are conducted once every four years. They are similar to the PISA tests, although the latter are less purely academically focused […]

Birth Defects, FBD Marriages

While researching a different topic I stumbled upon the following 2006 report on the Internet. It contains comprehensive estimates for the prevalence of birth defects all around the world. The relevant graph is reprinted below (you can click on it to get a bigger picture). What leaps out at first sight is the sheer extent […]

The Farewell To Alms Theory – Older Than We Think

I am currently (re)reading The National System of Political Economy by Friedrich List (published in 1841), and this jumped out at me: In no European kingdom is the institution of an aristocracy more judiciously designed than in England for securing to the nobility, in their relation to the Crown and the commonalty, individual independence, dignity, […]

Flynn Effect DOES Apply To South Korea

Regular readers of this blog may remember my comments regarding Ron Unz’s theory that East Asians have high IQ’s independent of time/nutrition/urbanization whatever it is that causes the Flynn Effect. Here is his original article on his theory of the “East Asian Exception” and my two responses are here and here. Anyway a new paper […]

Antisocial Punishment: Why China Will Defeat Corruption, But Russia And The Arabs Won’t

One of the books I’ve been reading lately is Steven Pinker’s massive door-stopper The Better Angels of Our Nature. Incidentally, I found it a very interesting read with tons of cool factoids, although it could have done with a third of its text and a tiny fraction of its liberal sanctimonious. But that’s for the […]

New Delhi Cuts Ties With PISA

India backs out of global education test for 15-year-olds. Indians were put to test for the first time in the last assessment in 2009. On the global stage, they stood second last among 73 countries, only beating Kyrgyzstan on reading, math and science abilities… This time around, sources said India shied away from the assessment as […]

Minorities’ Cognitive Performance In The UK

Here is data from the Cognitive Abilities Test for UK students in 2009/10 via Ambiguous. Some interesting things to take away here: (1) The sample is very large. Verbal IQ has the highest correlation with academic performance in most subjects, followed by Quantitative IQ, and then Non-Verbal Reasoning (recognizing patterns and such, I imagine). (2) Indians […]

Policy On Racism

As I noted in my old post on the false dichotomy between race denial and racism, there is a regrettable degree of overlap between racism and race realism. This shouldn’t however blind us to the real distinctions between the two, which were very succinctly summarized by Half Sigma thus: The race realist understands The g Factor, The […]

Analysis Of Russia’s PISA 2009 Results

A few months ago I posted a table and map of Russian IQ’s as derived from regional PISA performance. Those figures are based on Jarkko Hautamäki’s slideshow comparing regional PISA performance in Finland and Russia. That material is a bit inadequate because, as had been my custom up that point, I was only making IQ estimates based […]

rec1man On Indian IQ

My post on Indian IQ (max potential is low to mid 90’s) spawned an interesting analysis by commentator rec1man. It is not very well organized but he does have a ton of useful information that deserves to be highlighted. It’s reprinted in full below interspersed with occasional commentary by myself: Caste Analysis 75% of the Indian population gets […]

The Evolution Of Chinese IQ

In the discussion at the previous post, in which I took exception to Ron Unz’s theory of the East Asian Exception, he alerted me to so additional work on the matter he’d done as a Harvard freshman on Chinese IQ. You can read his summary of Social Darwinism and Rural China as well as Steve Sailer’s commentary on […]

Disagree With Ron Unz’s Conclusions On Chinese IQ

He writes: These scores are indeed truly remarkable, and completely confirm the apparent pattern of Lynn’s IQ samples, in which desperately poor East Asians tend to score at or above the levels of the most successful and well-educated Western populations… But since the total population is at least well into the hundreds of millions, heavily rural […]

Quantifying Future Time Orientation

In a 2010 paper on time preferences*, the authors Mei Wang et al. conducted an experiment in which participants could choose either $3400 now or $3800 a month later. Now I would choose the latter option but maybe it’s just because I’m intelligent and have been living in the West for quite a while. In […]

The Puzzle Of Indian IQ: A Country Of Gypsies And Jews

The question of Indian IQ is a big puzzle. Far trickier than China’s IQ which I think I’ve basically figured out (101-102 today; 106-108 genetic ceiling). The PISA-adjusted IQ of India – as extrapolated from the states of Tamil Nadu and Himachal Pradesh, which are relatively rich and are reputed to have good school systems by Indian […]

Analysis Of China’s PISA 2009 Results

As human capital is so important for prosperity, it behoves us to know China’s in detail to assess whether it will continue converging on developed countries. Until recently the best data we had were disparate IQ tests (on the basis of which Richard Lynn’s latest estimate is an IQ of 105.8 in his 2012 book […]

Olympic Observations

Now that the Olympics are drawing to an end, it’s now time for me to weigh in with my HBD / game perspective. (1) What is up with India? Only 5 medals. Record-setting (3 in Beijing, 0-2 in all previous Olympics) but that’s still atrocious for a country of 1.2 billion people – even a […]

Why Are Russian Chicks So Hot?

This is one of those stereotypes that is totally correct. Take a casual stroll about any Russian town and the typical woman you see would be considered “very cute” or “pretty” in places like the Germany, the UK or the US. And one or two of them will have supermodel looks. That kind of talent […]
