Testosterone and Difference between Men and Women

Review of Rebecca Jordan-Young's new book Brain Storm: The Flaws in the Science of Sex Differences - here:

"J
ordan-Young argues that the science of prenatal hormones, gender, and the mind "better resembles a hodgepodge pile than a solid structure." And she knows of what she speaks.

An expert on measures and study designs, Jordan-Young has spent the last 
13 years combing the literature on brain organization, unpacking assumptions, questioning methods and statistical practices, holding one paper up against another. She stresses that fetal hormones must matter to the brain—somehow. But after picking apart more than 400 studies that try to understand the genesis of particular psychological sex differences (real or supposed), she concludes that fetal T looks like an awfully anemic explanation.

This matters because the obsession with prenatal T can easily become a distraction. It can make us forget how much gender norms have changed—think of all those female accountants, lawyers, and doctors who weren't around 50 or even 30 years ago—and how remarkably similar men's and women's brains and minds actually are. All this unwarranted hammering away at difference (and its putative explanations) causes real trouble, too. As a growing body of research shows, cues that foreground gender and bring stereotypes to mind can dampen
men's performance on tests of social sensitivity, women's scores on math tests, and women's stated interest in quantitative pursuits Jordan-Young has done an enormous amount of work to untangle the gender claims. We ought to read her, cite her, thank her. And then, let's move on."
