For most people, that the disproportionate number of persons of Jewish ethnicity has more to do in educational related endeavors has more to do with a cultural tradition found in Jewish culture than world domination, does not have to be spelled out. For some, no matter what proof one would give, it wouldn't matter.
A demographic group that could be characterized as 'genetically less intelligent' by the small numbers that attain higher education might be the Hispanics. To do so though, would require one to ignore cultural as well as economic factors that enter into the make-up of that group, making that characterization most propably fallible.
Another would be the 'superiority' of Japanese or Chinese, like the Jews over represented in areas requiring higher education. To make that claim or generalization would be to overlook the cultural aspects of the group.
Of course, those that argue conspiracy theories or wish to justify prejudicial theses, must by definition use arguments that do ignore the obvious unaccounted for variables and hammer home the points they can make, relying on followers that do not make the connections.
