“Unlocking the Secrets of Your Genes: What Your Physical Traits Really Say About You!”

In 2009, Canadian researchers asked women if they could predict aggression in men by showing them neutral expressions of male faces. The women’s predictions followed a pattern: men with wider faces and a larger width-to-height ratio were predicted to be more aggressive.
This prediction has some scientific backing. According to the scientific journal Evolution and Human Behavior, high width-to-height facial ratios are often a result of more testosterone in the body. The more testosterone, the more likely a person is to become aggressive. However, this clearly isn’t saying that everyone with a broad face is violent.
