Say goodbye to Western civilization and Europe as you know it

>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.
