When equal does not mean "the same as"; on gender differences

From Rod Dreher, a link to a NY Times article, A New Frontier for Title IX: Science. From the article,

Until recently, the impact of Title IX, the law forbidding sexual discrimination in education, has been limited mostly to sports. But now, under pressure from Congress, some federal agencies have quietly picked a new target: science.

Yet, there were some interesting findings.

Despite supposed obstacles like “unconscious bias” and a shortage of role models and mentors, women now constitute about half of medical students, 60 percent of biology majors and 70 percent of psychology Ph.D.’s. They earn the majority of doctorates in both the life sciences and the social sciences. They remain a minority in the physical sciences and engineering. Even though their annual share of doctorates in physics has tripled in recent decades, it’s less than 20 percent. Only 10 percent of physics faculty members are women, a ratio that helped prompt an investigation in 2005 by the American Institute of Physics into the possibility of bias.

But the institute found that women with physics degrees go on to doctorates, teaching jobs and tenure at the same rate that men do. The gender gap is a result of earlier decisions. While girls make up nearly half of high school physics students, they’re less likely than boys to take Advanced Placement courses or go on to a college degree in physics.

What's more, conclusions were made which indicated that career choices were primarily determined by personality type (imagine that).

Once the researchers controlled for that personality variable, the gender gap shrank to statistical insignificance: women who preferred tinkering with inanimate objects were about as likely to go into computer careers as were men with similar personalities. There just happened to be fewer women than men with those preferences.

Now, you might think those preferences would be different if society didn’t discourage girls and women from pursuits like computer science and physics. But if you read “The Sexual Paradox,” Susan Pinker’s book about gender differences, you’ll find just the opposite problem.

Ms. Pinker, a clinical psychologist and columnist for The Globe and Mail in Canada...  argues that the campaign for gender parity infantilizes women by assuming they don’t know what they want. She interviewed women who abandoned successful careers in science and engineering to work in fields like architecture, law and education — and not because they had faced discrimination in science.

The money quote,

“Creating equal opportunities for women does not mean that they’ll choose what men choose in equal numbers,” Ms. Pinker says. “The freedom to act on one’s preferences can create a more exaggerated gender split in some fields.”
