Report: Men Unfaithful to Women Who Earn More - TIME
The study, which was presented by Christin Munsch, a sociology Ph.D. candidate at Cornell University, at the annual meeting of the American Sociological Association, examined 18 to 28 year olds who were living together or married more than a year. (The cohort, it turns out, most likely to be outearning men.) It found that men who were completely dependent on their wives' incomes were five times likelier to cheat than those who contributed the same amount to the household finances. (See a story on cheating 2.0: apps that are making adultery easier.)
Munsch believes this is not actually about money, but about men's feelings of sexual identity. "Any identity that's important to you, if you feel it's threatened, you're going to engage in behavior that will reinstate your place in that group," she says. "Being a man is strongly identified with being a breadwinner." Men might engage in "hypermasculine activities" — displaying their sexual virility or sexual competence — as a form of compensatory behavior.
