Y'know, the late Ernst van der Haag, a professor at NYU had an interesting theory.

He said that in the shtetls of Central and Eastern Europe, it was the Rabbi who was encouraged to have many children, and the best of the offspring of the rest of the village went to his children as spouses. So, the kids of the smartest guy in town (most numerous also) got the best of the rest and mated.

Over generations they produced intellectually superior people. Unprovable, but interesting nonetheless.

Jews are not the only closed gene pool with higher than average IQs....I think the urbanization of Jews since medieval times is a large contributor as well.
