I was planning to write a full response to this blog entry by Prof. Motl, about IQs as deduced by the GRE scores of applicants to various doctoral fields. But who cares? You can find and download Powerprep from the GRE website and examine the data for yourself. You'll need a Microsoft Windows PC.
I'll simply post two charts here, and note that if GRE scores are linearly related to IQ (as presupposed in the link) then the candidates for graduate school are not normally distributed in IQ. But it should be clear that GRE quantitative scores do not serve well to distinguish between candidates at the high end of the scores.
