When Joe Schmo has a gut feeling, Paul Ekman, a renowned expert in lie detection, sees microexpressions.
“A microexpression is a very brief expression, usually about a 25th of a second, that is always a concealed emotion,” says Ekman, PhD, professor emeritus of psychology at the University of California Medical School in San Francisco.
So when a person is acting happy, but in actuality is really upset about something, for instance, his true emotion will be revealed in a subconscious flash of anger on his face. Whether the concealed emotion is fear, anger, happiness, or jealousy, that feeling will appear on the face in the blink of an eye. The trick is to see it.
“Almost everyone — 99% of those we’ve tested in about 10,000 people — won’t see them,” says Ekman. “But it can be taught.”
In fact, in less than an hour, the average person can learn to see microexpressions.
