Richard Wiseman

How do you tell if someone is lying? When Richard Wiseman, Professor of the Public Understanding of Psychology at the University of Hertfordshire, conducted a nationwide experiment to identify the tell-tale signs, the results were surprising. If you want to spot a liar, don’t look at them. Listen to what they say and how they say it. in If you want to distinguish fact from fiction, radio, not TV or video is your friend. Visual cues distract us from what is being said and good liars can control their body language more easily than their voice. Depressingly, Richard has also shown that our nearest and dearest are the most able to deceive us.

Richard is a rare breed: a scientist who is also a practising magician. By the age of 17 he was performing magic tricks at children’s parties and a member of the exclusive Magic Circle. He chose to study psychology to try and understand why we believe the unbelievable and spent many years doing research on the paranormal: studying séances, haunted places and extra sensory perception. Could a belief in the paranormal be the price we pay for scientific discovery, he wonders?

Jim Al-Khalili talks to Richard about his magical Life Scientific and finds out more about his work on lying, ESP and luck. Are some people born lucky or is it a mind-set that can be learnt?
