We’ve intuited for ages that faces reflect personalities, and that we can “tell just by looking at them” what a person is really like. Some new research is bearing out our intuition, at least in the domain of aggression:
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.
