    It has been done before, and I'm not going to tell you how to do it. What is certain is that the results are so inconsistently reliable that polygraph evidence is not admissible in court.

    There are two weak links in a polygraph. The first is the operator. Doesn't make any difference how good they are or how much experience they have. Their reading one day with one subject can be different the next day with the same subject asking the same question. They are not scientific they are subject to interpretation and simply not reliable.

    How do you beat one? If you truly believe that a polygraph is the next thing to a Quija Board then all you have to do is declare that you do not believe nor trust in a polygraph and doubt that the operator can be consistent in their results, however you will take the poly but contest the results no matter what they show to the examiner. The fact that you made the declaration throws off the examiner's baseline and their results become tainted.

    Polygraph's should have gone by the wayside 50 years ago but most folk who sit down to take one are coerced into doing so by the situation (job, fear, etc).

    Pathological liars do that all the time, because in their mind they believe the lies they are telling is indeed the truth, so they display no deception, not physiological peaks on the polygraph to indicate that they are lying.If you belive deeply enough in yoiur lies, then you can easily beat the polygraphy. This is one big reson wht polygraph exam results are NOT admissible in court

    There are some theories about different ways. Not sure any really work. I've heard biting your tongue with each question would make the reflexes show up the same no matter what your responses are.
