"Not Sending Their Best": World Map of IQ Drop Due to Immigration

... the cognitive impact of immigration – at least as proxied by the differences in performance on the PISA tests between the national average, which includes immigrant children, versus only native children – is almost entirely negative for its supposed beneficiaries across the entire world.

Even those few countries with expressly “cognitively elitist” immigration policies see only the most modest of benefits: Singapore: +0.7; Canada: -0.1; Australia: -0.2.

Otherwise, the only countries not to be significantly affected are those which see little immigration in general, such as Japan and Korea. So perhaps the best way of “winning” the game to attract quality immigrants is to avoid playing it in the first place.

Western Europe is a complete disaster zone, getting a harder cognitive hit even though the immigrant share of their population is considerably smaller than the US, where they constitute almost a quarter of the PISA-taking population. The German national average takes an astounding 2.4 IQ point hit due to immigrants. Moreover, there is no full convergence between first and second generation immigrants. Although one can hope the children of all those Syrian “doctors and engineers” will go on to become productive and loyal citizens, past experience suggests that they will merely bolster the sullen ranks of a permanent, growing, ethnically distinct, and highly criminalized underclass.

The situation in the US is actually considerably better than in Europe – the low-IQ Central Americans, who are not sending their best, are counterbalanced by the millions of talented East Asians, Indians, and other intelligent and highly motivated people who still want to make America their home. Thanks to that the world’s biggest immigrant nation only loses 1.3 IQ points due to all the newcomers...

The UK doesn’t do too badly – only a 0.9 IQ point hit – because the Anjem Choudarys are partially canceled out by talented and ambitious Europeans. Many of the finance and technological firms in the City of London are majority staffed by talented foreigners. There are 200,000 French citizens in London.

Given the strong dependence between national IQ and economic prosperity, the globalist open borders project presents a serious challenge to the long-term viability of the First World cognitive engines that drive the vast bulk of technological progress – progress that is already threatened by the dysgenic trends embedded in post-Malthusian society and the banal fact that problems tend to get harder, not easier, as you ascend the technological ladder. This is not to even mention the risk of “institutional contagion” from newcomers who are culturally and perhaps biologically incompatible with that unique blend of individualism and commitment to the commonweal that facilitated the rise of European civilization...
