An Examination of the Associations Between Facial Structure, Aggressive Behavior, and Performance in the 2010 World Cup Association Football Players

Previous research suggests that facial-width-to-height ratio (FWHR) predicts aggression, unethical behavior, and non-reciprocity of trust. One limitation of this research is that all samples originate from western countries. To overcome this limitation, the present study investigates the relationship between FWHR and performance among association football athletes involved in the 2010 World Cup representing 32 countries. Results indicated that across all 32 countries, the associations between FWHR and athletic performance varied depending on position. FWHR positively predicted fouls within midfielders and forwards, and goals and assists within forwards. Collectively, these findings demonstrate the associations FWHR has with athletic behavior and performance for the first time in a well-varied multinational sample.
