Via Brutal Women, this NYTimes article gives some context to the arguments surrounding biological differences in men’s and women’s intelligence voiced by Harvard president Summers:
The modest size and regional variability of the sex differences in math scores, as well as an attitudinal handicap that girls apparently pack into their No. 2 pencil case, convince many researchers that neither sex has a monopoly on basic math ability, and that culture rather than chromosomes explains findings like the gap in math SAT scores.
Yet Dr. Summers, who said he intended his remarks to be provocative, and other scientists have observed that while average math skillfulness may be remarkably analogous between the sexes, men tend to display comparatively greater range in aptitude. Males are much likelier than females to be found on the tail ends of the bell curve, among the superhigh scorers and the very bottom performers.
Among college-bound seniors who took the math SAT’s in 2001, for example, nearly twice as many boys as girls scored over 700, and the ratio skews ever more male the closer one gets to the top tally of 800. Boys are also likelier than girls to get nearly all the answers wrong.
For Dr. Summers and others, the overwhelmingly male tails of the bell curve may be telling. Such results, taken together with assorted other neuro-curiosities like the comparatively greater number of boys with learning disorders, autism and attention deficit disorder, suggest to them that the male brain is a delicate object, inherently prone to extremes, both of incompetence and of genius.
But few researchers who have analyzed the data believe that men’s greater representation among the high-tail scores can explain more than a small fraction of the sex disparities in career success among scientists.

In the meantime, German scientists think women are bad drivers and poor map readers because of low testosterone and short index fingers. You know, it’s awfully hard to parallel park with hooves.
