Emil Kirkegaard et al. (2019) have just released Polygenic Scores Mediate the Jewish Phenotypic Advantage in Educational Attainment and Cognitive Ability Compared With Catholics and Lutherans:
A newly released multivariate polygenic score for educational attainment, cognitive ability, and self-rated mathematical ability in the Wisconsin Longitudinal Study was examined as a mediator of the group difference between Jews (n = 53) and 2 Christian denominations, Catholics (n = 2,603) and Lutherans (n = 2,027), with respect to educational attainment, IQ, and performance on a similarities measure. It was found that the Jewish performance advantage over both Catholics and Lutherans with respect to all 3 measures was partially and significantly mediated by group differences in the polygenic score. This result is consistent with the prediction that the high average cognitive ability of Jews may have been shaped, in part, by polygenic selection acting on this population over the course of several millennia.
(Well, there was Davide Piffer’s work, but it did not meet with wide acceptance).
Well, that’s about to change now. It has now been rigorously shown that Jews have more alleles associated with higher IQs than Caucasoid Gentiles. In other words, Jews have higher IQs at least partially (~50%) on account of genetic factors, not because they train for IQ tests, because society “privileges” them, or because of the Jewish culture of learning and hard work.
Many more such studies are on their way.
Racial blank slatism is going to become untenable within the next few years. Incidentally, due respect to Charles Murray, Razib Khan, and possibly some others I forget, who gave a window of 3-5 years back in 2016. They were exactly on the mark.
The only thing that remains to be seen is whether these landmark developments will spark the next scientific revolution, or whether the latter-day Lysenkoists ramp up enforcement of today’s politically correct orthodoxies.
