A new Canadian study, with a relatively small sample size, seems to suggest that's a possibility. We're talking about facial width-to-height ratio, so short, wide faces compared with long mugs. The study's author says there appears to be a relationship between wider-faced men and certain behaviours. The study, The Facial Width-to-Height Ratio Predicts Sex Drive, Sociosexuality, and Intended Infidelity, included 459 men and women around the age of 20. The study involved subjects self-reporting, as opposed to observed behaviour, so Bird warns it's important not to draw sweeping conclusions.
