Aggressive people are easy to spot because they have instantly recognizable
wide faces, researchers claim.
Just a quick glance at someone's facial structure may be enough to predict
their tendency towards aggression, according to a study published in the
Psychological Science journal found
Facial width-to-height ratio (WHR) is determined by measuring the distance
between the right and left cheeks and the distance from the upper lip to the
mid-brow.
Psychologists from Brock University in the USA decided to follow up on
previous research that suggested males with a large facial WHR act more
aggressively than those with narrower features .
In the study, volunteers viewed photos of faces of men who had previously
had their aggressive behaviour analysed.
The participants then rated how aggressive they thought each person was on
a scale of one to seven, after viewing each face for either 2000 milliseconds or
39 milliseconds.
The results revealed the participants' estimates of aggression correlated
highly with the actual aggressive behaviour of the men - even if they only saw
the picture for a split second.
And the volunteers' estimates also matched with the WHR of the faces the
wider the face, the higher the aggressive rating.
The psychologists concluded that subtle differences in face shape may
affect personality judgements, which in turn, guide how people respond to
others.
During childhood, boys and girls have similar facial structures, but during
puberty, males develop wider features than females.
Previous research has suggested that males with wider faces act more
aggressively - with studies showing that hockey players with broad features earn
more penalty minutes per game than other players .
