How Do People 'Fool' Lie Detector Tests...?

You don't really "fool" them, but you may wind up with an inconclusive test. I doubt it is ever anything intentional. The polygraph detects changes in the body induced by the stress of lying. If you do not have a conscience, or if you don't know right from wrong, your body may not go through any measurable change during a lie. For a normal person, I would think the more you tried to lie, the more change your body would go through.

I had heard of people making the test inconclusive by getting themselves all charged up somehow. Since the test picks up stress during lies, a really hyper person might register stress on truths, confusing the test. If you register a lie when you correctly state your name, it puts other answers in doubt. Of course, you will not get away with this.

See the shortcut I have attched. It explains that the lie detector does not detect lies but merely changes in the body to questions asked. There are some tips on how to fool it. http://www.wikihow.com/Cheat-a-Polygraph-Test-(Lie-Detector)

There is a technique. I'm not going to detail it. However, polygraph (lie detector) examiners are trained to be able to detect when a person is attempting to "fool" the test. It will not go over well if you are caught doing this....

Very few people fool lie detectors. When you try, it throws the whole test off and they come to " no conclusion".

Thats what ive always wanted to know BEEP BEEP ooops i failed the test

I have lied to a lie detector test and passed. They thought us how to do this in case we were captured by enemy forces and subject to torture. We would claim we were tourists on a sight seeing trip, but if they looked at the footage... yowza... THE KEY! 1)stay calm; moderate your heart rate 2)fool yourself into thinking it is the TRUTH 3)you are not LYING; you are telling the TRUTH from your point of view I just found out that a person could rent DVD's online and I found a god place, but I was wondering where other people do it??
