Why Men Cheat More Than Women
New research suggests men succumb to sexual temptations more than women — for example, cheating on a partner — because they experience stronger sexual impulses, not because they have weaker self-control.
Recently published in Personality and Social Psychology Bulletin, the study was composed of two experiments. The first was designed to determine how the different sexes reacted to real-life sexual temptations in their past, while the second was designed to pick apart sexual impulses and self-control using a rapid-fire reaction time task.
“Overall, these studies suggest that men are more likely to give in to sexual temptations because they tend to have stronger sexual impulse strength than women do,” said Natasha Tidwell, a doctoral student in the Department of Psychology at Texas A&M University, who co-authored the study.
“But when people exercise self-control in a given situation, this sex difference in behavior is greatly reduced. It makes sense that self-control, which has relatively recent evolutionary origins compared to sexual impulses, would work similarly — and as effectively — for both men and women.”
For the first experiment, researchers recruited 70 male and 148 female participants from the United States.
The participants were asked to describe an attraction to an unavailable or incompatible member of the opposite sex. They then answered survey questions designed to measure strength of sexual impulse, attempts to intentionally control the sexual impulse, and resulting behaviors.
“When men reflected on their past sexual behavior, they reported experiencing relatively stronger impulses and acting on those impulses more than women did,” Tidwell said.
However, men and women did not differ in the extent to which they exerted self-control, she noted.
“When men and women said they actually did exert self-control in sexual situations, impulse strength didn’t predict how much either sex would actually engage in ‘off-limits’ sex,” added Tidwell.
“Men have plenty of self-control — just as much as women,” add co-author Paul Eastwick, Ph.D., an assistant professor in the Department of Human Development and Family Sciences at The University of Texas at Austin. “However, if men fail to use self-control, their sexual impulses can be quite strong. This is often the situation when cheating occurs.”
For the second experiment, designed to measure the strength of sexual impulse relative to the strength of impulse control, the researchers recruited 600 undergraduate students — 326 men, 274 women — to participate in a “Partner Selection Game.”
Participants were very briefly shown images of opposite-sex individuals; the images were tagged either “good for you” or “bad for you.” Participants were asked to accept or reject potential partners based on the computer-generated “good for you” or “bad for you” prompt.
While they were shown photographs of both desirable and undesirable individuals, participants were instructed to make acceptance and rejection choices based on the computer-generated tags.
In some trials, participants were asked to accept desirable and reject undesirable individuals; in other trials, participants were asked to go against their inclinations by rejecting desirable individuals and accepting undesirable individuals.
Men experienced a much stronger impulse to “accept” the desirable rather than the undesirable partners, and this impulse partially explained why men performed worse on the task than women, according to the researchers.
However, this same procedure estimates people’s ability to exert control over their responses, and men did not demonstrate a poorer ability to control their responses relative to women, the researchers noted.
