Slowly but surely we’re finding out more about the symptoms of telling lies.
Researchers at Portsmouth University and universities in Italy asked 130 volunteers to make a series of honest and dishonest statements and then evaluated their movements.
Contrary to popular belief, liars fidget less than non-liars. This is because, says Dr Samantha Mann: “People who are lying have to think harder, and when we think harder we tend to be a lot stiller, with fewer movements, because we are concentrating harder.”
Then, studying the behaviour of suspects in police interviews, Mann found that, when lying, participants paused more in their speech and blinked less frequently. Eyes for lies who wrote a guest post here says that the finding of a lack of blinking by liars confirms her experience as a human lie detector.
Debunking another myth, Mann found that liars were just as likely as an honest person to look a questioner in the eye.
Just as some people like ‘Eyes’ are savants at picking lies, one wonders whether some people are liar-savants.
