Smart people are more likely to be forgetful, tend to be rebellious in their younger years, and—apparently—are less likely to cheat in relationships, too. Business Insider recently shed more light on the topic of infidelity, including why there's a growing gender divide in terms of why women and men cheat on their partners.
A 2010 study published by Social Psychology Quarterly found that men with higher IQs were "less likely to want to be unfaithful." The research analyzed survey responses from thousands of adults and teenagers in the U.S. and found "intelligent men are more likely to value monogamy and sexual exclusivity than less intelligent men," writes Satoshi Kanazawa, a professor at the London School of Economics and Political Science and author of the study.
The reason? From an evolutionary standpoint, modern men are able to shed their "caveman" instincts to have as many mates as possible, and it's those who are considered less smart who are unable to shake off the basic drive to cheat. However, it's worth noting that the researchers also discovered a clear difference between preference and behavior: Intelligent men were more likely to simultaneously "value sexual exclusivity and more likely to engage in extramarital affairs."
Business Insider also notes that women and men tend to cheat for different reasons, according to science. A 2008 study published in American Sociological Review found that women who are the breadwinners in their relationship are less likely to be unfaithful. The findings discovered that both male breadwinners who earned 70% of their household's income and men who were financially dependent on women were also more likely to cheat.
That's not all: A more recent study conducted in 2013 by the Kinsey Institute at Indiana University—which defined "cheating" as "engaged in sexual interactions with someone other than their partner that could jeopardize, or hurt, their relationship"—discovered that women cheated on their partners at nearly the same rate as men.
