Variation in the facial width-to-height ratio was positively correlated with alpha status and a composite measure of assertiveness. This novel finding adds to a growing body of evidence indicating that variation in facial structure reliably maps onto individual differences in dominance-related phenotypes
To the extent that variation in the facial width-to-height ratio (fWHR) is under the influence of pubertal testosterone, and that pubertal testosterone organizes the neural circuitry underlying sexually dimorphic behaviors, we tested the hypothesis that this metric would map onto human aggression

Introduction

Edited by: Thomas Bugnyar, University of Vienna, Austria Reviewed by: Robert Orrin Deaner, Grand Valley State University, USA Jorg J. In their paper, Lefevre et al (2014) reported positive correlations between fWHR, alpha status, and “assertiveness.” The latter construct consisted of traits such as bullying, aggression, dominance, jealousy, and stinginess.
