I would never purport to be an expert in genetics or evolution, but it

seems to me “Jewish intelligence” is much more due to culture than

genetics. As Jonah says, “Jews valued education, literacy etc for its

own sake.” This is a people that defines themselves by a book, and

then proceeds to devote a large portion of their intellectual energy

arguing about what that books means. Contrast that with the world’s

other major religions, which don’t ignore study, but certainly place

greater emphasis on faith, meditation, or obedience.
