Why do people cheat? It’s a question we get (and address) here at ScienceOfRelationship.com regularly. Our coverage of the topic generally reflects the state of research on the topic, which focuses on proximal predictors of infidelity --- or science jargon for those things about individuals or relationships that directly increase the likelihood somebody will cheat, such as low commitment, more attractive alternatives, lack of impulse control, narcissism, and so on. But what if we dig further in a person’s history, perhaps even preceding her or his foray into the world of romantic and sexual relationships? Are there more distal signs or risk factors for whether somebody will one day cheat on a partner? It would appear so.
