Proofiness and the Gender Gap

In a fine piece at City Journal Kay Hymowitz considers the reasons which have been advanced to explain why there's a gap between the incomes of males and females and concludes that, contrary to what we often hear from folks who see injustice lurking in every social disparity, there's nothing nefarious about the gender gap. She also concludes that it'll never go away. Here are some excerpts:
Early this past spring, the White House Council on Women and Girls released a much-anticipated report called Women in America. One of its conclusions struck a familiar note: today, as President Obama said in describing the document, “women still earn on average only about 75 cents for every dollar a man earns. That’s a huge discrepancy.”

It is a huge discrepancy. It’s also an exquisite example of what journalist Charles Seife has dubbed “proofiness.” Proofiness is the use of misleading statistics to confirm what you already believe. Indeed, the 75-cent meme depends on a panoply of apple-to-orange comparisons that support a variety of feminist policy initiatives, from the Paycheck Fairness Act to universal child care, while telling us next to nothing about the well-being of women.
Hymowitz goes on to show the fallacies inherent in some of the explanations of the alleged inequities:
Let’s begin by unpacking that 75-cent statistic, which actually varies from 75 to about 81, depending on the year and the study. The figure is based on the average earnings of full-time, year-round (FTYR) workers, usually defined as those who work 35 hours a week or more. But consider the mischief contained in that “or more.” It makes the full-time category embrace everyone from a clerk who arrives at her desk at 9 am and leaves promptly at 4 pm to a trial lawyer who eats dinner four nights a week—and lunch on weekends—at his desk.

I assume, in this case, that the clerk is a woman and the lawyer a man for the simple reason that—and here is an average that proofers rarely mention—full-time men work more hours than full-time women do. In 2007, according to the Bureau of Labor Statistics, 27 percent of male full-time workers had workweeks of 41 or more hours, compared with 15 percent of female full-time workers; meanwhile, just 4 percent of full-time men worked 35 to 39 hours a week, while 12 percent of women did. Since FTYR men work more than FTYR women do, it shouldn’t be surprising that the men, on average, earn more.
She also has little patience with the claim that women make less money than men who perform the same job:
But proofers often make the claim that women earn less than men doing the exact same job. They can’t possibly know that. The Labor Department’s occupational categories can be so large that a woman could drive a truck through them. Among “physicians and surgeons,” for example, women make only 64.2 percent of what men make. Outrageous, right? Not if you consider that there are dozens of specialties in medicine: some, like cardiac surgery, require years of extra training, grueling hours, and life-and-death procedures; others, like pediatrics, are less demanding and consequently less highly rewarded.

Only 16 percent of surgeons, but a full 50 percent of pediatricians, are women. So the statement that female doctors make only 64.2 percent of what men make is really on the order of a tautology, much like saying that a surgeon working 50 hours a week makes significantly more than a pediatrician working 37.
Even so, she's willing to concede that there remains a gap between male and female income, but to impute it to discrimination, as is often done, is simply an argument from ignorance:
The point is that we don’t know the reason—or, more likely, reasons—for the 7 percent gap. What we do know is that making discrimination the default explanation for a wage gap, as proofers want us to do, leads us down some weird rabbit holes. Asian men and women earn more than white men and women do, says the Bureau of Labor Statistics. Does that mean that whites are discriminated against in favor of Asians? Female cafeteria attendants earn more than male ones do. Are men discriminated against in that field? Women who work in construction earn almost exactly what men in the field do, while women in education earn considerably less. The logic of default discrimination would lead us to conclude that construction workers are more open to having female colleagues than educators are. With all due respect to the construction workers, that seems unlikely.
So, what might account for the gap if not gender discrimination?
So why do women work fewer hours, choose less demanding jobs, and then earn less than men do? The answer is obvious: kids. A number of researchers have found that if you consider only childless women, the wage gap disappears. June O’Neill, an economist who has probably studied wage gaps as much as anyone alive, has found that single, childless women make about 8 percent more than single, childless men do (though the advantage vanishes when you factor in education). Using Census Bureau data of pay levels in 147 of the nation’s 150 largest cities, the research firm Reach Advisors recently showed that single, childless working women under 30 earned 8 percent more than their male counterparts did.

That’s likely to change as soon as the children arrive. Mothers, particularly those with young children, take more time off from work; even when they are working, they’re on the job less. Behind the Pay Gap found that “among women who graduated from college in 1992–93, more than one-fifth (23 percent) of mothers were out of the work force in 2003, and another 17 percent were working part time,” compared with under 2 percent of fathers in each case. Other studies show consistently that the first child significantly reduces a woman’s earnings and that the second child cuts them even further.
Of course, anyone with common sense knew that the mommy track was the primary explanation for the wage disparity, but common sense is not an abundant resource among ideologues determined to find injustice in every nook and cranny of our society. Sometimes one has to resort, as does Hymowitz, to a calm recitation of the facts.

Anyway, there's much, much more on this at the link, and those of a sociological inclination will want to read it all. It's something of an aesthetic pleasure seeing the shibboleths of conventional opinion deconstructed in front of one's very eyes.
