How Do You Raise Your National IQ?

Anatoly Karlin writes: There are several ways to influence national mean IQ levels. One is to improve nutrition and education, but vitally important though they are, they suffer from diminishing returns as populations bump up against their genetic ceilings. Another is to promote eugenic policies, or at least policies to mitigate the dysgenic trends that are typical of modern developed societies, but they tend to be ethically questionable and politically unfeasible. The third major lever is the immigration system, but how can we assess whether it’s doing its job of only letting in the people who would be a net benefit to the host country?

…One thing that immediately leaps out from above is that just as US scores leap upwards (from 496 to about 525, in line with Australia and Canada) once only whites are considered, so do scores in many European states when only natives are considered (e.g. Germany from 510 to 533; Switzerland from 517 to 542; the Netherlands from 519 to 533). In fact, the countries mentioned above and a few others equalize with Japan’s 529, Taiwan’s 534, and South Korea’s 541 (the natives of these developed East Asian societies also score a lot higher than their immigrants, but the overall effect on the national average is modest because migrant children are such a small percentage of their school-age populations). In other words, in the worst affected European countries, immigrants are lowering the mean national IQ (converted from PISA scores) by as much as 3 points.

This might not seem like much, but it is highly significant when bearing in mind the extremely close correlation between national IQ and prosperity. Furthermore, since immigrant populations tend to be highly variant – for instance, Britain has a lot of Poles, who are essentially equal to the natives in cognitive capacity (maybe even superior, once you adjust for the fact that it is better-educated Poles who tend to emigrate), and a lot of Pakistanis, who are far below them. This is a good explanation for the general sense of dereliction one sees (and the crime one is likely to experience) when entering Pakistani ghettos in the UK…

(4) The US (-4) has an idiotic immigration system that penalizes highly-qualified workers while being relatively lax at controlling (inevitably unqualified, lower-IQ) illegals from Central America. But nonetheless, it’s an economic and technological dynamo, and despite policy failures there are still plenty of high-IQ immigrants.

(5) Spain (-5), Italy (-6), Norway (-7), Sweden (-9), the Netherlands (-9), France (-9), Germany (-10) and Belgium (-11) have progressively worse quality immigrants relative to the natives in their countries. (The reason for why the Med countries do “better” than the Teutonic ones isn’t because they have better immigrants, but because their native IQ’s are lower). Unlike the US, they tend to have few highly-qualified immigrants, as English speaking (and typically lower tax) nations like Australia, the US, etc. are more attractive to high-IQ cosmopolitans. What’s more, a big proportion of the immigrants to Europe are Muslims, whose faith and habits conflict with local mores to a far greater extent than Catholic Hispanics clash with the indigenous American culture.

(6) In countries like Dubai, Qatar, Kazakhstan, and Israel, the higher quality of immigrants is presumably due to the fairly low human capital of the host nations themselves…

IQ is closely correlated with any number of highly important things like productivity, criminality, civic-mindedness, welfare dependency, etc. and research is converging on the view that IQ is highly heritable and that different ethnic groups have different genetic IQ ceilings. This is all reflected in the far lower average cognitive capacities of the immigrant populations of Europe, and to a lesser extent, the US and Canada, relative to that of natives.
