underlyingtruth,

Your on the right thought process, but I will define to you what you are looking for. The polygraph (or the polygrapher) needs 3 tenents for the voodoo to work. I have repeated this multiple times but here goes.

1 - The subject must have fear and anxiety going into the procedure. Lack of Knowlege guarantees this, at least this was the case until this website and others showed up. Reading and understanding the procedure reduce this fear and anxiety.

2 - Subject must believe unconditionally that the machine works and is capable of detecting the slightest falsehood. Thats the reason for stim tests, and the schtick the polygrapher has to go through for you to believe. An example is them claiming there experience and accuracy and they have caught so many liars, etc etc, etc. Its all a mind game to get you to believe, nothing more.

3 - Subject must have consequences for failing the test. THis adds to the anxiety and produces the desired tension level neccessary.  If you have read and studied and practiced then this is not a problem, as you have the right to refuse any polygraph. Or as the case may be to use countermeasures to seek a successful exploitation of the procedure. 

Unless the polygrapher has all three, best case you will pass, worst case inconclusive .. Either way you win. And your inner secrets remain intact. Much success to you. 

I hope this clairifies what you need.
