None of the many I know.  At least to my knowledge.  Just like any group they are obviously all over the map.  My personal experience is that Jews do tend to be unusually interesting and fun to discuss things with.

I will say that those who subscribe to certain ideas in the Babylonian Talmud are pretty damn close to ol' Nick.  That would include Kabbalahists and the many spin-offs from that belief system.  That's what my research points to at least.

I did watch an interesting presentation by one Doreen Dotan recently who seems to be a remarkably forthright person.  She claims to be from a Rabbinical family who regularly married 1st cousins to try to maintain academic achievement.  She says that her family has a lot of smart people and a lot of psychopaths and she figures that there is a relationship in brain function.  According to my own personal theories of neurology I would not rule such a thing out.  Unknown how widespread such a inbreeding structure is (if it's not complete BS from the get-go) but really it would take only a small fraction of a particular group to have a significant impact over time...human society being what it is.
