Hur bra är vi på att avslöja en lögn?

I So How Do You Spot a Liar? berättas om en undersökning hur bra vi är på att avslöja någon som ljuger.

... But the latest psychological research suggests we are not as good at spotting deception as we think we are. The average rate of lie detection is just 44 per cent, which is a worse result than we would get if we based decisions on the toss of a coin.

It is this body language which holds the real key to detecting lies. A change in body language as the sophisticated interviewer switches from a topic where it is known the interviewee is telling the truth to one where lying is possible can be a real giveaway.

I en annan artikel Study shows language loss may improve ability to spot lying beskriver man en grupp som verkar klara lögndetektion något bättre.

While previous research – including studies conducted by Ekman – has shown that people in general have only a 50/50 chance of detecting when someone is lying by their expression or tone of voice, the aphasia patients were able to detect lies cued by facial expression alone 73 percent of the time. The other study groups all had close to 50 percent accuracy in recognizing lies tied to facial expressions. The aphasia patients also did better than the other groups in detecting lies cued by both facial and vocal changes – 60 percent compared with about 45 percent. None of the groups did well in recognizing lies cued by changes in vocal pitch alone.
