Men's facial width-to-height ratio predicts aggression: a meta-analysis

Michael P Haselhuhn et al. PLoS One. .

Abstract

Recent research has identified men's facial width-to-height ratio (fWHR) as a reliable predictor of aggressive tendencies and behavior. Other research, however, has failed to replicate the fWHR-aggression relationship and has questioned whether previous findings are robust. In the current paper, we synthesize existing work by conducting a meta-analysis to estimate whether and how fWHR predicts aggression. Our results indicate a small, but significant, positive relationship between men's fWHR and aggression.
