Once a Cheater, Always a Cheater? Here's What the Science Says

Once a Cheater, Always a Cheater? Here's What the Science Says

Is it a bad idea to get romantically involved with someone you know has committed infidelity in the past? Common sense tells us that "once a cheater, always a cheater." However, it's dangerous to rely on common sense to understand sex and relationships because research doesn't always back it up and also because different people can hold very different "common sense" beliefs. We need to look instead at what science says about whether past infidelity predicts future infidelity,

"Common Sense" Isn't A Substitute For Scientific Research

"Common Sense" Isn't A Substitute For Scientific Research

I spend a lot of time talking, writing, and tweeting about the latest scientific research on sex and relationships. Over the years, I've had more than a few people respond to my posts and articles with comments like, “We needed research to tell us this?” In other words, it's not uncommon for people to question whether a given study was ever needed because we could have used “common sense” to figure out the results instead.

Couric brought in two experts to discuss this issue, but when one of them (Dr. David Ley, author of The Myth of Sex Addiction) dared to mention that the research examining the effects of porn on kids isn’t so black and white, Couric wasn’t having any of it. For instance, according to Ley:

“There are good research studies that show that adolescents’ use of pornography explains only 2% of the variance in their behavior in relationships, drug use, or behavior problems later on. That’s important. We are over-focusing on pornography because sex, masturbation, and pornography are ‘scary.’”
