Will we always be able to lie and get away with it? A new breed of lie spotters and lie catching machines are hot on our trail. One machine - reputedly unbeatable - actually checks what information is stored in the brain.
We all lie. And we do it much more than most of us like to admit. But will we always be able to lie and get away with it? A new breed of lie spotters and lie catching machines are hot on our trail...
Although parents scold their children for lying, and try to teach them the importance of telling the truth, learning to lie is in fact a crucial stage in child development. Realising others don't necessarily know what we know, and using that to our advantage is something the smartest children pick up first.
But as we get older, we have to learn when not to lie. Socially, being discovered as a liar can be disastrous, and when the stakes are high, our lies have the biggest chance of being spotted simply from our demeanour - that's because the brain and body are trying hardest to conceal our true feelings. Someone who knows what to look for can spot these tell tale signs quite easily. Psychologist and expert lie catcher Paul Ekman shows us some classic big stakes lies -- and what gives them away.
