Just for the record, J. Philippe Rushton, whom the op-ed draws on as a classic source of this kind of work in psychology, was a white-supremacist race "scientist" who argued, among other things, that black people have narrower hips because they have smaller brains. The Southern Poverty Law Center has a file on him: http://www.splcenter.org/get-informed/intelligence-files/profiles/jean-philippe-rushton http://www.splcenter.org/get-informed/intelligence-files/pro...
