Facial asymmetry is negatively related to assertive personality but unrelated to dominant personality in men

Fluctuating asymmetry (FA) is a putative indicator of development instability in humans and other species, and some literature supports a women’s preference for low degree of FA in opposite sex (e.g., symmetrical face). Also some personality traits associated to social status (e.g., dominance and assertiveness) are attractive to women due to direct and indirect benefits associated to high status. The aim of this work was to study the relationship between facial FA and dominant and assertive personalities. We found a negative correlation between facial FA and assertive personality but not between facial FA and dominant personality. Moreover, we found a positive correlation between assertive and dominant personality. Our results suggest that a low facial FA and assertive personality can be related to be advertising desirable traits and high status in men in order to be more attractive to women. This study supports the evidence shown by previous works which shows that a low facial FA is related with socially desirable and attractive aspects of personality.
