link to more on this study so i can critique it properly? i personally believe there is a very minor g-advantage in ashkenazim over europeans caused by the same factors that cause their genetic conditions - inbreeding - along with eugenic controls on jewish populations over millenia by rebbes/cohens. but it amounts to around 2-3.5/4 points at most and comes with negative personality traits and mental disorders - it's not a clear eugenic case of higher intelligence as you find in euros or ne asians because it comes with severe detrimental traits. it's a dysgenic mistake caused by inbreeding with a specific social structure and rabbinical control of mate-matching that causes a lot of mental illness while also, to a small extent, boosting average iq.
