I suggest going back to school on your basic terms. Skin color taxonomies such as "white" and "black" are weak proxies for genetic diversity. Races are not taught this way anymore. This article in Scientific American puts it well in summarizing that "the mainstream belief among scientists is that race is a social construct without biological meaning."^1 "Ashkenazi Jews ... have higher IQ scores than whites" is a nonsensical statement from that perspective. You are mixing categories of ancestry and skin color. The authors of Bell Curve made the same basic mistake and were rightly skewered for it.

Apply principal component analysis to human DNA, and not only does race pop out, it even coincides with the 'socially constructed' categories [1,2,3]. A 2009 survey of physical anthropologists in Europe by Katarzyna Kaszycka found that 51% (N=123) recognize biological race - 33% in Western Europe, and 70% in Eastern Europe [4]. In a review of China's only biological anthropological journal Acta Anthropologica Sinica, 324 article from the 1982-2001 period that dealt with human variation. The researchers found that "all of the articles used the race concept and none of them questioned its value" [5].

Do you have studies that use better taxonomies of "race"? Or do you mean any statement about race is so confounded by social factors it becomes nonsensical.

Also, The original claim was:

> Every result ever has pointed that all races and genders are..

If you muddy the water wrt race, it invalidates the above claim also.
