Angry words and gestures are not the only way to get a sense of how temperamental a person is. According to new findings in Psychological Science, a quick glance at someone’s facial structure may be enough for us to predict their tendency towards aggression. Psychologists Justin M. Carré, Cheryl M. McCormick, and Catherine J. Mondloch of Brock University conducted an experiment to see if it is possible to predict another person’s propensity for aggressive behavior simply by looking at their photograph. Volunteers viewed photographs of faces of men for whom aggressive behavior was previously assessed in the lab. The volunteers 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 photographs were very revealing: Volunteers’ estimates of aggression correlated highly with the actual aggressive behavior of the faces viewed, even if they saw the picture for only 39 milliseconds. These findings indicate that subtle differences in face shape may affect personality judgments, which may, in turn, guide how we respond to certain individuals.
