THE GIST Economically dependent men are more likely to cheat on their female partners.

THE SOURCE “The Effect of Relative Income Disparity on Infidelity for Men and Women,” by Christin L. Munsch, Cornell University.

Here’s a useful nugget for misogynists and man-haters alike: The more a man depends on his female partner’s paycheck, the better the chances he will cheat.

“Having multiple sex partners may be an attempt to compensate for feelings of inadequacy,” suggests a paper presented at the 105th annual meeting of the American Sociological Association in August. The study looked at 18- to 28-year-old married and cohabiting heterosexuals who had been in the same relationship for at least a year. Data was culled from the continuing National Longitudinal Survey of Youth begun in 1997.

Men who were completely dependent on their female partner’s income  the vaunted Stay at Home Dad, for example, and his less appreciated cohort, Laid-Off Dad  were five times more likely to cheat than men who contributed an equal amount of money to the relationship. And, in a cruel twist for women, men who earn significantly more than their female partners are also more likely to cheat.
