Most of the studies cited were pretty flawed in implementation iirc. The paper you linked also fails to mention the most probable reason for Jewish success, which imo is the community itself. More specifically, the n-word, nepotism. I have a very Jewish name, and I've experienced preference for it. I think this also presents unique opportunities for access to early, high value education, regardless of socioeconomic status, which definitely skews the IQ results.
