THE GIST A man minds less when a woman cheats on him with another woman than with another man.

THE SOURCE “Sex Differences in Response to Imagining a Partner’s Heterosexual or Homosexual Affair,” by Jaime C. Confer and Mark D. Cloud, published in Personality and Individual Differences.

Dude! Finally, research to explain many a male fantasy and Judd Apatow movie. According to a new study by Jaime C. Confer, a doctoral student in psychology at the University of Texas at Austin, and her father, Mark D. Cloud, a psychology professor at Lock Haven University in Pennsylvania, a man is more than twice as likely to continue dating a woman if she has cheated on him with another woman than if she has cheated on him with another man.

The daughter-father duo asked 700 college students to imagine that they were in a committed romantic and sexual relationship with someone for three months, then asked how they would respond to infidelity on the part of the hypothetical partner. Some were told the affair was repeated, others that it was a solitary incident. Some learned their imaginary partners had had sex with multiple partners; others, that it had been only one person.
