Your genes might have gotten you into monogamy, and they might be getting you out. That’s one takeaway from a recent YouTube video by AsapSCIENCE explaining the science behind why people cheat on their partners.
Turns out only about 3 percent of mammals are monogamous, and that includes humans. But as you might have learned from the high school lover who ripped your heart out at a tender young age, not all humans are monogamous all the time — and there are a lot of factors at play: genetics, hormones, and even differences in salary.

Researchers have found a link between gene coding of the brain’s dopamine (“happy hormone”) receptor and likelihood of cheating in men and women. According to AsapSCIENCE, “One study found that 50 percent of people who possess the long variant of this gene had cheated on their partner, compared to only 22 percent of people who have the short variant.” If you’re prone to risk-taking and addictive behavior, you should probably get the length of your variant checked (or, you know, just don’t cheat on your partner).
The video claims another factor could be disparity in income, because stay-at-home dads and men who earn far more than their spouses are more likely to cheat than guys who earn about the same as their spouses. If you’re worried because you’re a chronic risk-taker who earns far more than your partner, fear not: Fate is still in your hands. And hey, at least you’re the life of the craps table.
