Will Saletan defends research into the neurobiological differences between men and women. But he also cautions against over-interpreting research:
Before you attribute sex differences in behavior or success to evolution, check the record. Today’s differences may not have existed yesterday and may not exist tomorrow. The percentage of math Ph.D.'s awarded to women in the 1950s, according to Hyde, was half what it was in the 1890s and one-sixth of what it is today. Several panelists targeted the word hardwired as a misleading metaphor for explaining the brain. Brains, unlike computers, are constantly altered by experience.
