Boyfriend More Forgiving When Her Affair Is With a Woman
MONDAY Jan. 31, 2011 -- A man is much more likely to continue dating a girlfriend who cheated on him with another woman than a girlfriend who had sex with another man, a new study finds.
However, a woman is more likely to stick with a man who had sex with another woman than a man who had an affair with another man.
The findings provide new insight into the general male desire to have a number of sex partners and the general female desire to have a committed partner, said the researchers at the University of Texas at Austin.
"A robust jealousy mechanism is activated in men and women by different types of cues -- those that threaten paternity in men and those that threaten abandonment in women," study author Jaime C. Confer, a doctoral candidate in evolutionary psychology, said in a university news release.
The study included 700 college students who were asked to imagine they were in a committed relationship and how they would respond to different types of infidelity.
Among men, there was a 50 percent likelihood they would continue to date a girlfriend who had a lesbian affair, and a 22 percent likelihood they would stay with a woman who had a heterosexual affair.
Among women, there was a 28 percent likelihood they would keep dating a boyfriend who had a heterosexual affair, and a 21 percent likelihood they would stay with a man who had a homosexual affair.
The study was published in the January issue of the journal Personality and Individual Differences.
