From studio 3B in Rockefeller Centre, here is Stone Phillips. It might make for an interesting experiment - what if you can develop a foolproof lie detector and carry it around with you all day. Who would be caught telling lies? Your friends, your family, your boss, you? Well, tonight it’s NBC week-long series on dishonesty in America. I look at why so many people lie, cheat and steal. You gonna meet a man who maybe the closest thing there is to a portable lie detector and perhaps he can show you what to look for to catch people lying to you. Here’s Sarah James.
Song: You can't hide your lying eyes and your smile…
Lie, deceive, misrepresent, perjure, defraud, subterfuge, dishonesty, prevaricate. A thousand words describe a picture of the world where lying and deception seem to be everywhere. From notorious lies…
Layer: Are you therefore saying that you have not use that word in the past ten years detective Fuhrman?
Detective: Yes, that is what I'm saying.
To monstrous lies…
Susan: I would like to say to whoever has my children…
To lies to the name of country…
Solder: I want you to know that lying does not come easy to me…
But how can you tell if someone is lying? Is it as easy as this father who cautions his son in the 1948 movie The Winslow Boy?
Father: If you tell me a lie, I shall know it, because a lie between you and me cannot be hidden.
Psychologist Paul Ekman thinks it’s not so easy, most people he says, including judges, lawyers, police and even FBI agents are very poor in detecting lies, but Ekman made a career out of it.
Journalist: Can you tell when someone lies?
Ekman: I do about 80-90% accurate, if the stakes are high. And that’s really important, it really has to matter to the liar whether they get caught or not.
So if the lie is trivial, all bets are off. But if the liar has something to gain by lying, and a lot to lose if he’s caught, Paul Ekman would usually catch him red-handed.
Ekman: So you look for discrepancies, things that don’t fit. The speech doesn’t fit the voice, the voice doesn’t fit with the face, the body movements don’t fit with anyone of them. There is no clue that works for everyone.
Take Susan Smith, the mother convicted of drowning her two sons.
Susan: My children are my life.
At first, there was no indication she was lying, but soon, said Ekman, the lie became too difficult to maintain.
Susan: Our lives have been torn apart by this tragic event.
Ekman: Have you seen enough? There’s no emotion going on here, she’s trying to put some in her voice, but she is not succeeding. It’s not in her face, there are no tears, her face is totally flat.
Susan: I want to say to my babies that your mama loves you so much and your daddy...
Ekman: See that was just totally unbelievable performance, just totally unbelievable. She’s trying…
Besides evaluating general behaviour, Dr Ekman says that a good lie catcher must pay attention to specific emotional clues. Watch Kato Kaelin’s testimony in the O. J. Simpson trial.
Prosecutor: Mr Kaelin you’ve got a lot of money for your appearance on your current affair, didn’t you? Kaelin: Um, yes.
Notice anything unusual? Paul Ekman did.Ekman: Can you back that? Oh that’s it. Now slowly forward. Little more. Okay. That’s a micro-expression. That’s his real feeling towards the prosecutor.
Journalist: Anger, does not like.
Ekman: Aww...Okay. Just comes out for a moment.
Prosecutor: You don’t have a book proposal?
Kaelin: No
Prosecutor: You don’t have a book proposal out?
Kaelin: No. Don’t wanna do a book.
A drop in voice level, one possible sign, says Ekman, of a lie.
[11:50 – end]
How can someone be a better lie catcher? Ekman says you can start by remembering the two basic clues.
Ekman: So the science of thinking, that you should need to do; and the science of emotion, that don’t fit what you’re saying. And above all, give them a chance to reveal themselves.
Susan: They just got to be okay.
Ekman: The more someone talks, the more likely it is they’re gonna make a mistake that you’ll be able to pick up on.
Now you’re lying to me now. No I’m not.
Ekman also urges people to be a little more skeptical, he says liars are often not caught because too many of us really believe that others are telling us the truth.
