New research explores why people cheat on their spouses. This cross-cultural research shows three consistent findings:
- Love for a spouse makes people less likely to cheat.
- Finding other people attractive makes people more likely to cheat.
- Thinking that one’s spouse is cheating makes people more likely to cheat.
Essentially, love for a spouse helps prevent against infidelity, but being attracted to other people and thinking that your spouse is cheating is associated with higher levels of infidelity.
