How To Spot a Psychopath

Having a wider face has been linked with higher levels of attraction and aggression, and now research has suggested it may also be a sign of psychopathy.

A study of students and prison inmates found that men with a higher facial width-to-height ratio were more likely to exhibit what’s known as ‘self-centred impulsivity’.

They also showed signs of ‘fearless dominance’ as well as a tendency to blame other people for problems.

Self-centred impulsivity is a category of traits including Machiavellian egocentricity and is the tendency to consider only personal needs, with a disregard for the interests of anyone else.

Those high in self-centred impulsivity also tend to neglect the social norms and regulations that the rest of us live by.

Fearless dominance, meanwhile, includes a tendency to embrace risk without any fear, showing limited reaction to awful events that would make the rest of us panic – combined with a tendency to appear charming and influential.
