Can science explain why people cheat on their partners?
Some takeaways from the video:
- only about 3% of mammals are monogamous
- “the gene coding for a dopamine receptor plays a key role in cheating for men and women”
- dopamine, which is released after a pleasurable activity, is also called as the ‘happy hormone’
- “one study found that 50% of people who possess the long allele variant of this gene had cheated on their partner, compared to only 22% of people who have the short allele”
- Low levels of vasopressin, which affect trust, empathy and social bonding, have an influence on cheating
