Facial symmetry is not a reliable cue of aggressive behavior

Abstract

Some evolutionary psychologists argue that facial symmetry provides cues as to the behavioral tendencies of the target. The present study examined the relationship between facial symmetry and aggressive behavior in healthy young people. To this end, the frontal photographs of 158 male and 154 female university students were taken and recent version of Buss & Perry aggressiveness questionnaire was used for detecting self reported aggressive behavior. The analysis of facial symmetry from pictures was done on the basis of 14 somatometric landmarks in NIH-Image 1.62 by using Spearman’s rank correlation analysis no significant relationship was found between composite asymmetry and any component of aggressiveness. The results of the study suggest that facial symmetry is not a reliable cue of self reported aggressiveness in young males and females living in Ankara, Turkey.
