Economic dependence may lead a small percentage of men and women to cheat on their spouses, according to a new study by Christin L. Munsch, an assistant professor of sociology at the University of Connecticut. She explained in a press release that “people like feeling relatively equal in their relationships. People don’t like to feel dependent on another person.”


Her data came from the National Longitudinal Survey of Youth, which consisted of 2,750 married people between the ages of 18 and 32.

She said that in a year, women who were economically dependent on their husbands have a 5 percent chance that they’ll cheat. In the reverse situation, the chance a man will have an affair on his wife is around 15 percent.

Munsch explained the disparity in infidelity in a press release:

“For men, especially young men, the dominant definition of masculinity is scripted in terms of sexual virility and conquest, particularly with respect to multiple sex partners. Thus, engaging in infidelity may be a way of reestablishing threatened masculinity. Simultaneously, infidelity allows threatened men to distance themselves from, and perhaps punish, their higher-earning spouses.”

These sentiments have been echoed before, from a male perspective, by Rabbi Shmuley Boteach, a TV and radio host, in his Big Think interview. Where Munsch argues that economic dependence causes imbalance in the relationship, leading to infidelity, Boteach focuses on the bigger topic of self-esteem that causes some men to stray:
