How does it work in the "moment of truth" show? I don't see any wires attached?

Question

I know from movies and books that there has to be wires attached to one's body. Like wires that can measure any change in the heart rate.

So, how can they tell just by the voice? I don't get it.

Answer 1

They have the lie detector done BEFORE the show. They have about 50 questions they ask the person and then only air about 25 of them (if they get to the highest amount of money).

The trick is- they have to be truthful with the first test and then MATCH the answer they said first. It could possibly be hard to do this- if your not truthful.

Its an actually pointless show. They completly embarass (or even ruin) the person. I would never go on it- no matter how much money they give me. Peace.

Answer 2

Stuff like that is my reason for not watching TV.

Answer 3

They do a lie detector test, before the actual taping. So they can know what the correct answers are. The show is all about admitting c**p. It is so addicting though. Best Answer pleaseeee?
