Objective: In recent years, several researchers have focused on the relationship between fluctuating asymmetry and aggression. These studies reveal conflicting results. In this study, we examined the relationship between bodily symmetry and self-reported aggressive behavior in healthy young people living in Turkey.
Methods: The sample comprised of 100 male and 102 female university students recruited from Cumhuriyet University, Sivas. The Buss and Perry aggressiveness questionnaire was used. Four bilateral traits were measured for fluctuating asymmetry analysis. For the subsequent statistical analyses, only the composite asymmetry index was used.
Results: There was no relationship between composite asymmetry and any component of aggressiveness for either sex.
Conclusions: Our findings for people living in Turkey did not support the hypothesis that aggressiveness, as a signal of evolutionary fitness, is related to developmental instability.
