Dysgenic Trends in Iceland

The minor allele of one of these SNPs, rs192818565, is associated with reduced education. It is known to tag the H2 haplotype of a common inversion on chromosome 17 that was shown to exhibit characteristics consistent with having been positive-selected (23). It has subsequently been shown that H2 is also associated with reduced intracranial volume (24, 25) and neuroticism (26). Combining our male and female data, the minor allele of rs192818565 is significantly associated with more children (P = 5.2 × 10⁻³) and having children earlier (P = 2.2 × 10⁻³). This is thus a striking case where a variant associated with a phenotype typically regarded as unfavorable could nonetheless be also associated with increased “fitness” in the evolutionary sense.  Source. 

G. Cochran writes that we are seeing in front of our eyes evolution of IQ, so it follows that there are differences among living populations, and also we shall discover them in dead - historical  - populations.  I think all the debate about dysgenic trends in Western populations is finished and we should focus on how to digest this knowledge.

The Communist Party (see Yefim Lysenko's case) and the Left fought and are fighting the idea of IQ evolution. The Nazis with their fake Race Science provided them with a powerful alibi (and constituency) that inhibited the advance for a hundred years.  The whole thing is very badly positioned in the West and we can only say, like Galileo, that "eppur si muove".

P.S.:  Continuing the above point, let me observe that there are many illustrations of the above dysgenic trend. Just to mention one:

Two oil paintings by renowned Icelandic painter Gunnlaugur Blöndal (1893-1962), were removed from the Central Bank of Iceland after one staff member complained. Blöndal  painted most of his nudes in the 1930's and 1940's. The removal of the painting has caused some uproar as it only features a bare breasted woman and because Blöndal is one of Iceland's most celebrated artists. 

"Certain warning lights start blinking when people are offended by what we call classical imagery," says director of the National Gallery of Iceland, Harpa Þórsdóttir.
