Not personally, but I have heard tales of pathological liars beating the polygraph

The tips you here belong on mythbusters, especially the old "tack in the shoe." Nowadays you sit on a pressure pad that detects tensing any muscles in your leg.
I did have a friend that could get away with lying when he was told to during the calibration phase. He didn't try lying during the test. The polygrapher told him some people did not register well and some people did not show indicators of dishonesty when instructed to lie.
The test is not perfect but it is pretty accurate.

A Polygraph is only as good as the person running the machine....There is a lot of training involved to be a Polygraph operator. I guess that is why it has never been admissible in court......Good Luck

All polygraph machines do is measure how nervous you are. If you are just a nervous person you will likely fail whether or not you lie. However if you are a smooth, confident person there is a chance that you could pass the test while lying.

Polygraphs are based of the physiological response to lying:therefore someone who does not TRULY believes in the lye they are telling will not pass a polygraph. IE: a pathological liar will pass...

Polygraphs are notoriously unreliable - that's why they are not permitted in court. Anything can effect the outcome from just being nervous to having a heart problem to no apparent reason at all.
No court permits the results of a polygraph test to be used in a trial....

It happens all the time, The polygraph reacts to moisture .pulse, heartbeat. If you are a physopathical liar and really believe what you are saying is the truth you wont register. One of the reasons they are not admissible in court

I know a "friend of a friend" that did. From what was "told to me" is that he had taken his aunts medication, mind you she is a nurse and the prescription was (nexium) heart burn stuff. Where infact he had said he took nothing.. Passed..
Poly's and backgrounds don't know what you have done unless you tell them. If you can keep your cool and stick to the story your fine.
On the other hand this happens vise versa. He didn't do anything and the poly was stating he was "lying" Those machines are "Junk science" Courts don't credit them, why should anyone else?
Besides, the police can legally lie to ya..

It is not 100%. Some people pass it while lying and some people fail it while telling the truth.

Yes, a tack in the shoe is an old way to get past the poly. Stick yourself a few times even while telling the truth and you'll skew the baseline.
