Averages and Gender

Here is a well thought article from the New Republic on the Larry Summers affair and how their really are some gender distinctions, but that what applies to group statistics and averages does not necessarily apply to individuals in the group. You would think that this is obvious, but for many of Summers critics is is not.

"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 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.

Many of Summers's critics believe that talk of innate gender differences is a relic of Victorian pseudoscience, such as the old theory that cogitation harms women by diverting blood from their ovaries to their brains. In fact, much of the scientific literature has reported numerous statistical differences between men and women. As I noted in The Blank Slate, for instance, men are, on average, better at mental rotation and mathematical word problems; women are better at remembering locations and at mathematical calculation. Women match shapes more quickly, are better at reading faces, are better spellers, retrieve words more fluently, and have a better memory for verbal material. Men take greater risks and place a higher premium on status; women are more solicitous to their children."
