who are the real experts?
in fact, the only two groups of people who are good at spotting liars are US secret service agents and clinical psychologists who are doing research into lying. they don't rely on one single clue and lack of eye contact, but they notice and interpret many different signals that liars often give out. these signals, which are different for each liar, can be verbal and non-verbal they indicate all the emotion which the liar wants to keep hidden: guilt, despair, anger, fear, even pleasure, verbal clues include using a higher voice, making speech errors,or pausing. non-verbal signs include things like touching your nose, leaning towards the listener, and playing with small objects such as a pen.
