Social interactions may sometimes collide and result in conflicts which can be solved among others by means of physical violence. However, physical confrontations entail a risk of injuries and other fitness-affecting consequences. Thus, it seems likely that cognitive and behavioural processes to assess the fighting ability may have evolved by means of natural selection. This would facilitate adaptive decisions and responses to decrease costs and increase benefits from potential confrontations. Behavioural characteristics are often assessed according to physical traits such as facial appearance. People are relatively accurate in attributions of certain characteristics from facial traits, like physical strength or propensity for aggression. However, previous research was not based on data about actual fighting ability. Therefore, we conducted a series of empirical studies testing perception of formidability, accuracy of the perception and attempted to identify facial morphological traits related to the assessments and actual fighting performance. To test these issues, we employed Mixed Martial Arts contestants and used their record of victories and defeats. The results of our first study revealed that people are indeed able to relatively accurately assess the fighting ability of others. The fighting...
