Oh, those Harvard boys

In Sex Ed, Steven Pinker discusses the negative reaction to Harvard President Lawrence Summers' remarks at a conference on gender imbalances in science, in which he raised the possibility of innate sex differences. Pinker points out
... the belief, still popular among some academics (particularly outside the biological sciences), that children are born unisex and are molded into male and female roles by their parents and society is becoming less credible. Many sex differences are universal across cultures (the twentieth-century belief in sex-reversed tribes is as specious as the nineteenth-century belief in blood-deprived ovaries), and some are found in other primates. Men's and women's brains vary in numerous ways, including the receptors for sex hormones. Variations in these hormones, especially before birth, can exaggerate or minimize the typical male and female patterns in cognition and personality. Boys with defective genitals who are surgically feminized and raised as girls have been known to report feeling like they are trapped in the wrong body and to show characteristically male attitudes and interests. And a meta-analysis of 172 studies by psychologists Hugh Lytton and David Romney in 1991 found virtually no consistent difference in the way contemporary Americans socialize their sons and daughters. Regardless of whether it explains the gender disparity in science, the idea that some sex differences have biological roots cannot be dismissed as Neanderthal ignorance.
Then he argues that people have reacted so strongly against Summers' remarks because he violated a taboo:
The psychology of taboo is not completely irrational. In maintaining our most precious relationships, it is not enough to say and do the right thing. We have to show that our heart is in the right place and that we don't weigh the costs and benefits of selling out those who trust us. If someone offers to buy your child or your spouse or your vote, the appropriate response is not to think it over or to ask how much. The appropriate response is to refuse even to consider the possibility. Anything less emphatic would betray the awful truth that you don't understand what it means to be a genuine parent or spouse or citizen. (The logic of taboo underlies the horrific fascination of plots whose protagonists are agonized by unthinkable thoughts, such as Indecent Proposal and Sophie's Choice.) Sacred and tabooed beliefs also work as membership badges in coalitions. To believe something with a perfect faith, to be incapable of apostasy, is a sign of fidelity to the group and loyalty to the cause. Unfortunately, the psychology of taboo is incompatible with the ideal of scholarship, which is that any idea is worth thinking about, if only to determine whether it is wrong.

At some point in the history of the modern women's movement, the belief that men and women are psychologically indistinguishable became sacred. The reasons are understandable: Women really had been held back by bogus claims of essential differences. Now anyone who so much as raises the question of innate sex differences is seen as "not getting it" when it comes to equality between the sexes. The tragedy is that this mentality of taboo needlessly puts a laudable cause on a collision course with the findings of science and the spirit of free inquiry.
But Pinker's a man, so can we believe him?
