More by Steven Pinker on the Larry Summers Brouhaha

From The New Republic:

Pinker Anyone who has fled a cluster of men at a party debating the fine points of flat-screen televisions can appreciate that fewer women than men might choose engineering, even in the absence of arbitrary barriers. (As one female social scientist noted in Science Magazine, “Reinventing the curriculum will not make me more interested in learning how my dishwasher works.”) To what degree these and other differences originate in biology must be determined by research, not fatwa. History tells us that how much we want to believe a proposition is not a reliable guide as to whether it is true. 

Nor is a better understanding of the causes of gender disparities inconsequential. Overestimating the extent of sex discrimination is not without costs. Unprejudiced people of both sexes who are responsible for hiring and promotion decisions may be falsely charged with sexism. Young women may be pressured into choosing lines of work they don’t enjoy. Some proposed cures may do more harm than good; for example, gender quotas for grants could put deserving grantees under a cloud of suspicion, and forcing women onto all university committees would drag them from their labs into endless meetings. An exclusive focus on overt discrimination also diverts attention from policies that penalize women inadvertently because of the fact that, as the legal theorist Susan Estrich has put it, “Waiting for the connection between gender and parenting to be broken is waiting for Godot.” A tenure clock that conflicts with women’s biological clocks, and family-unfriendly demands like evening seminars and weekend retreats, are obvious examples. The regrettably low proportion of women who have received tenured job offers from Harvard during Summers’s presidency may be an unintended consequence of his policy of granting tenure to scholars early in their careers, when women are more likely to be bearing the full burdens of parenthood.

Conservative columnists have had a field day pointing to the Harvard hullabaloo as a sign of runaway political correctness at elite universities. Indeed, the quality of discussion among the nation’s leading scholars and pundits is not a pretty sight. Summers’s critics have repeatedly mangled his suggestion that innate differences might be one cause of gender disparities (a suggestion that he drew partly from a literature review in my book, The Blank Slate) into the claim that they must be the only cause. And they have converted his suggestion that the statistical distributions of men’s and women’s abilities are not identical to the claim that all men are talented and all women are not–as if someone heard that women typically live longer than men and concluded that every woman lives longer than every man. Just as depressing is an apparent unfamiliarity with the rationale behind political equality, as when [Nancy] Hopkins sarcastically remarked that, if Summers were right, Harvard should amend its admissions policy, presumably to accept fewer women. This is a classic confusion between the factual claim that men and women are not indistinguishable and the moral claim that we ought to judge people by their individual merits rather than the statistics of their group.
