Salary Gender Gap May Be All in Your Head

Not only is the gender gap in pay persistent, it affects men as well as women. Men with traditional views on a woman's place in the world earn, on average, $12,000 more per year than men who believe in egalitarian business practices, the Washington Post reports. Traditionally minded women make the least of all, according to a new study.

The study, which covers the last quarter-century, looked at men and women working similar jobs, with similar hours and lengths of tenure. Controlling for those variables dispelled some long-held conventional wisdom, suggesting that "a lot of the difference may be in men's salaries," says a study co-author. Traditional-minded men may negotiate harder for higher wages, and employers may discriminate against men who flout stereotype by holding egalitarian attitudes.
