Hormones, Genes and the Corner Office

The New York Times, 9 March 2008, Book Review THE SEXUAL PARADOX By Susan Pinker ---- By Emily Bazelon



Why do girls on average lead boys for all their years in the classroom, only to fall behind in the workplace? Do girls grow up and lose their edge, while boys mature and gain theirs?

Ten years ago, no one would have thought to ask. The assumption that boys dominated at school as well as at work, while girls were silenced or ignored, seemed beyond dispute. But in her new book, “The Sexual Paradox,”
a ringing salvo in the sex-difference wars, Susan Pinker stacks up the evidence of boys’ classroom woes and girls’ triumphs. “In the United States, boys are three times as likely to be placed in special education classes, twice as likely to repeat a grade and a third more likely to drop
out of high school,” she writes. Tests of 15-year-olds in 30 European countries show girls far outstripping boys in reading and writing and holding their own in math. Boys are overrepresented in the top 1 percent of math achievers, but there are also more of them at the bottom. A 2006
economics study showed universities practicing affirmative action for men so that superior female applicants wouldn't swamp them. “If you were to predict the future on the basis of school achievement alone,” Pinker writes, “the world would be a matriarchy.”

And yet, of course, it is not. Once they move from school to work, men on average earn more money and run more shows. They particularly dominate in national government, the corporate boardroom and the science laboratory.
Meanwhile, women are more likely to leave the labor force and to end up with lower pay and less authority if they come back.

Pinker, a psychologist and a columnist at The Globe and Mail in Canada, is careful to remind her readers that statistics say nothing about the choices women and men make individually. Nor does she entirely discount the effect
of sex discrimination or culture in shaping women’s choices. But she thinks these forces play only a bit part. To support this, Pinker quotes a female Ivy League law professor: “I am very skeptical of the notion that society
discourages talented women from becoming scientists,” the professor writes. “My experience, at least from the educational phase of my life, is that the very opposite is true.” If women aren't racing to the upper echelons of science, government and the corporate world despite decades of efforts to woo them, Pinker argues, then it must be because they are wired to resist the demands at the top of those fields.

Thus, Pinker parks herself firmly among “difference” feminists. Women’s brains aren't inferior, she argues, but they vary considerably from men’s, and this is the primary explanation for the workplace gender divide. Women
care more about intrinsic rewards, they have broader interests, they are more service-oriented and they are better at gauging the effect they have on others. They are “wired for empathy.” These aren't learned traits; they’re the result of genes and hormones. Beginning in utero, men are
generally exposed to higher levels of testosterone, driving them to be more competitive, assertive, vengeful and daring. Women, meanwhile, get a regular dose of oxytocin, which helps them read people’s emotions, “the truest social enabler.” Then there’s prolactin, which, along with oxytocin, surges during pregnancy, breast-feeding and caretaking. Together, the hormones produce such a high that mother rats choose their newborns over cocaine.

Many of the scientific claims are familiar from previous books that pump up findings on sex difference, like “The Female Brain,” by the neurologist Louann Brizendine. Pinker goes even further by drawing a straight line from
those blissed-out rats to human mothers who dial back at work. Because of their biological makeup, she argues, most women want to limit the amount of time they spend at work and to find “inherent meaning” there, as opposed to domination. “Both conflict with making lots of money and rising through the ranks,” she points out.

Pinker is surely right to contest what she calls the “vanilla male model” of success - “that women should want what men want and be heartily encouraged to choose it 50 percent of the time.” Or that when employers say
jump, employees should always say how high. Even as they work fewer hours for less status and less money, on average, more women report that they are satisfied with their careers. Maybe men might well think the same if more
of them felt they could cut back. But Pinker’s difference feminism doesn’t really allow for that possibility. She is a believer: “The puzzle is why the idea of sex differences continues to be so controversial,” she writes.

In her zeal, Pinker veers to the onesided. She doesn’t acknowledge that some of the research cited in her footnotes is either highly questionable as social science (Louise Story’s 2005 article in The New York Times,* for
instance, about her survey of Ivy League women’s aspirations) or has never been replicated - like the findings from Simon Baron-Cohen’s laboratory that newborn girls showed more interest in looking at human faces, while
newborn boys preferred mechanical mobiles. Pinker omits the work of scientists who have shown that sex-based brain differences pale in comparison to similarities. We shouldn't wish the role of sex differences away because they’re at odds with feminist dogma. But that doesn't mean we
should settle for the reductionist version of the relevant science, even if the complexity doesn't make for as neat a package between hard covers.

Pinker also doesn’t acknowledge that some scientists wouldn’t accept the premise behind her chapters about male fragility. She cites men with Asperger’s syndrome and attention deficit disorder as examples of what she
calls the “extreme male brain.” These men are train wrecks in school but then get on track in adulthood, when they can focus singlemindedly on their chosen fields. Pinker argues that their experience helps explain the general male lag at school and jump ahead at work. It’s true that men are
more likely than women to suffer from Asperger’s and from some forms of A.D.D. But do their particular outsize talents and deficits really shed light on the workings of the average man’s brain? That question is hardly settled, and Pinker seems a bit glib when she fails to say as much.

Pinker also skips past an answer to the book’s central question that may have more explanatory power than her other arguments, even if it’s more prosaic and familiar to many a parent. Boys lag dramatically behind girls
in terms of psychological development and physical resilience and then start to catch up as teenagers, as a long-running and wellknown study Pinker cites documented. Maybe after a few years as girls’ developmental
equals, boys are ready to compete in the work force — and then zoom ahead as cultural norms and discrimination push women back. After all, why would girls’ hard-wired predilection against competition stay on ice while they
blithely sweep all the academic honors and then kick in only at work?

Despite such unanswered questions, Pinker deserves credit for hacking away at the vanilla male model. She is right to point out that “grueling hours do not always translate into productivity” and to seethe at employers for
ratcheting up their demands “even while extolling the virtues of gender balance.” And she is also right to call on schools to give the troubles of boys a fair share of attention. Pinker may not convey all the complexity that goes into making many men’s and women’s lives different, but she has a good prescription for helping more of us be our best selves.
