The polygraph, when properly used has a high degree of accuracy, highter than any other method of detecting deception. This is why government agencies such as the FBI, CIA and Military rely on the instruments and methods. The polygraph has a documented accuracy in excess of 95% when administered by a qualified examiner in accordance with American Polygraph Association standards.
There are those that insist the polygraph can be beaten but they are usually attempting to sell such information on the Internet. The polygraph records physiological responses from emotions resulting from the fear involved in what an examinee believes to be the truth. The only way to truly fool a polygraph is for the examinee to honestly believe what is counter to the actual facts. About the only way one can believe something counter to the true facts is:
1. Honest and innocent mistaken belief.
2. Being insane or pathological.
3. Undergoing extensive hypnotherapy and other memory altering techniques intended to actually erase the examinees knowledge of the truth and deceive an examiner. This would have to be done well in advance of, and in anticipation of the examination such as with espionage and can be done only under clinical conditions. Such a scenario would not likely be available in the average criminal mind that tends to commit crimes spontaneously.
There are theories and techniques that individuals can read about on the Internet or purchase through mail order and might be tempted to try during an examination.
But one must realize that the professional psychophysiologist also reads those same techniques and test them out on his or her system, and with other colleagues of the profession in order to identify when an examinee is attempting such measures. When the skilled examiner observes the examinee using them he simply declares the examinee as deceptive because of his attempt. In effect the examinee fails the polygraph test anyway.

I'll believe it if someone in the polygraph business passes a polygraph while saying they work.

NOT EVEN CLOSE!!!!!! Ive done major research on that stuff and its just a farce big time. It all depends on your pulse and respiration's which can change at any given time of the day. Its pretty much speculation and the usual that cops are so good at doing-INTIMIDATION! The voice stress analysis is invented by a man that is not even a doctor but proclaims himself as being one and their was no scientific data to back up his machine! How he marketed this thing is way beyond me but he managed but 60 Minutes did a big spiel about how he lied and how the machine had no data to prove his claims. So there you have my analogy of the things.

No. Polygraphs only record bodily reactions to some might call "nerve-racking questions"

yes sometimes ..... but i also believe certain people can also sail through it with a breeze and be lying the whole time. I know my ex was in the military and well they train them on things like that and how to pass them.

They indicate you are nervous. If you are nervous about being asked, they can give a false negative. But only a psychopath can beat them on a lie.

polygraphs can be beaten

I believe it works on those who believe it works. And it doesn't work on those who don't believe it works. That's why they don't use it in court.
