There is an overrepresentation of ashkenazis in classical music, for example. I don't think jews are any smarter than whites but it's cope to think they are dumb and just cheating IQ tests. What really separates jews isn't IQ it is some kind of genetic propensity for degeneracy and subversion. It seems to follow them everywhere they go, in every era, they seek to defile and corrupt the prevailing moral order. I think this is something separate from IQ.
