Can we tell when people are lying? A rebroadcast from 2007

Published: July 17, 2017, 2:01 a.m.

I was searching through my old podcasts and I came up with another one from 2007 that seems to be pertinent to today's world. This one was on liars.
According to a study 50% of people questioned thought they could tell when someone was lying. The data suggested we were not that good at telling when someone was lying to us. Is that true?
This podcast presented some of the reasons why we cannot always tell who is telling the truth or who is lying. I think it is very relevant today!
