All the mau-mauing by the faint-hearted women scientists and feminists has compelled Larry Summers to back down from his perfectly reasonable speculation on one of the causes of the numerical disparity between men and women in the professions of science and math. Too bad.

I hoped that he would say something like the following: "I'm sorry that my remarks were so misinterpreted by so many who should be more capable of calm, rational analysis. I hope that they'll go back and read them again. I also regret that this incident has shown so many in academia to be antithetical to the spirit of debate and free inquiry. Perhaps, though, this can be a lesson for us all, and used as a basis to discuss the broader issues of how dissenting speech has been shut down on campuses all over the nation."

Alas, it was not to be. Sadly, he basically retracted instead. I hope that when he left the press conference, he at least muttered, under his breath, "E pur si muove..."

Coincidentally, research results published in the past week by Haier and colleagues at UCI indicate that, on average, men have about 6.5 times as much grey matter as women, and women have about 10 times as much white matter. According to the release "Gray matter represents information processing centers in the brain, and white matter represents the networking of – or connections between – these processing centers." Overall though, they end up leading to equivalent overall performance with respect to cognitive ability.
