I found this to be an instructive tale.
I don't know if you have seen it or not, but Fox is airing a new show [actually taken from another show in Latin America] whereby contestants are asked questions in front of a live audience for millions of viewers to watch and if they tell the truth they win money. Sort of like truth or dare, but without the dare. The twist is that they've already been asked hundreds of questions beforehand while hooked up to a detector and then they are asked a small subset of those questions [the spicy ones] again on stage.
On Monday's show - taped two weeks ago - one particularly cruel and greedy woman - Lauren - was a contestant. Lauren's ex-boyfriend made a surprise appearance and asked:
"Do you believe I am the man you should be married to?"
As Lauren's hubby Frank Cleri grimaced on the sidelines, his wife said, "Well, wow, um. I'm going to be honest and say yes."
The lie-detector results said she was being truthful, and she was awarded $100,000. She beamed with pride despite the fact she had just humilated her husband on television and trashed their marriage.
Later, after admitting that she cheated on Frank, and netting another $100,000, she was asked if she thought she is a good person.
She answered, "Yes," but the lie-detector test said she was lying. She lost all of the money.
For me, the question is, did she know she was lying, or was this lie one that she had talked herself into on a conscious level and her true subconscious assessment of her character came out through the lie-detector? We will never know.
