HEATHER MAC DONALD: Gender Is a Construct—Except When It’s Not: For academic feminists, male and female biology is either interchangeable or immutable, depending on what complaint they need to lodge.

A foundational tenet of academic feminism holds that alleged differences between males and females are socially constructed. This credo usually maximizes the opportunities for charging sexism, yet it will be discarded in an instant if acknowledging the innate biological and psychological differences between men and women yields an additional trove of feminist complaint. The current issue of the Yale Alumni Magazine shows how the game is played.

For years, medical research neglected “sex and gender differences” in health, according to the magazine. “Historically, the narrative of medicine has been driven by data derived from white men around the age of 40,” the associate dean for curriculum at the Yale Medical School told the magazine’s reporter. Clinical trials only occasionally included females and when they did, the results were rarely analyzed by sex. It’s mysterious why this alleged neglect should matter, if sex differences are “socially constructed.” If males and females are the same psychologically and physically before the patriarchy starts assigning sex roles, then medical research need not distinguish between males and females, either.

It turns out, however, that males and females differentially respond to stress, environmental risk factors, drugs, and disease, as an initiative called Women’s Health Research at Yale devotes itself to documenting. . . .

Such discoveries should be the death knell for social constructivism. Along with many others like them, they buttress the possibility that uneven sex ratios in various fields are in part the result of males and females’ different average dispositions toward competition, risk, and abstract rather than people-centered work (an observation that got computer engineer James Damore fired from Google).

And yet, feminist social-justice warriors are perfectly capable of proceeding on several contradictory fronts simultaneously.

Which itself reinforces a stereotype about women . . . .
