  10.  @irtakus a short follow up on the Flynn effect… it is not as extreme as you portrayed it and there is zero reason to believe it will solve any of our immigration problems but the effect is indeed real. The obvious candidate reasons are better nutrition, less pollution/poison, fewer diseases/parasites, and better education/more books. We would expect the poor to be more afflicted by all four and we do in fact see a much stronger Flynn effect historically amongst the poor than among the middle class/rich. Longer schooling didn’t have much of an effect, though. It has also stopped in rich, industrialized countries. And even poor people in the Middle East and most of Africa have better nutrition and a lower disease load than middle class Europeans had a hundred years ago… There is a funny error source, though. Some IQ tests are more affected by education than others. Raven’s progressive matrices (which is nice because it is culture neutral and easy to administer) is very affected but most others show only a tiny effect or no effect at all. That means you have to be careful when you hear about a study that purports to show a strong recent Flynn effect: you need to verify what test(s) it used. We have very good data on the Flynn effect for Moroccan migrants to the Netherlands, thanks to Jan ter Nijenhuijs (which I probably misspelled). The first generation had an average IQ in the low 80’s and the second generation in the high 80’s… and I think it used Raven’s progressive matrices. So, not much hope of them reaching 100 anytime soon :(
