There is ample scholarly work to suggest that Ashkenazi Jews, at least, have significantly
higher IQs than surrounding populations. In Natural History of Ashkenazi Intelligence,
Gregory Cochran, Jason Hardy, and Henry Harpending of the University of Utah conclude that
“Ashkenazi Jews have the highest average IQ of any ethnic group for which there are reliable
data. They score 0.75 to 1.0 standard deviations above the general European average,
corresponding to an IQ of 112-115.
