How to Spot Liars

Can you tell when people are lying? Here a retired FBI agent or a government crime investigator talks about identifying lies. He was a polygraphic examiner. A polygraph is a machine that records people's feelings when they talk. Sometimes criminals are asked to take a polygraph or a lie detector test. If you fail a polygraph, it often means you were lying.

Listen to this news report and try the quiz. The former FBI agent uses a proverb or wise old saying, "The eyes are a window to the soul". He adds, "You can see right through them." It's interesting to know right and left handed people lie differently. Also, have you ever noticed people are uncomfortable when they lie?
