Attractive people are less likely to cooperate with others, and more likely to focus on their own interest, according to a new study

Spanish researchers had volunteers participate in “Prisoner’s Dilemma“-type games and found that those with the most symmetrical facial features generally took the selfish option, whereas less symmetrically-faced folks tended to cooperate for the greater good.

In general, the more symmetrical a person’s face, the more attractive they are considered.

The study’s authors then concluded that evolution has made good looking people more selfish:

“As people with symmetrical faces tend to be healthier and more attractive, they are also more self-sufficient and have less of an incentive to cooperate and seek help from others,” they write.  “Through natural selection over thousands of years, these characteristics continue to the present day.”
