Buy a biofeedback machine, Radio Shack or Sharper Image or places like that. Maybe around $30 iirc. Make sure it has two finger positions for the GSR. Pretend like you're on fire or falling and see how the activity indicators (lights, beep/tone, etc.) increase, then relax, and note how they decrease as well. That is only if you need proof you can control your body's reactions with absolutely no way a polygrapher can detect a CM like that. All you need to do is spike yourself to react more to control questions than to relevant questions. It works, believe me.

It is probably more accurate to write that few (if any) people on this board, other than polygraph examiners, have any "practical knowledge or experience" which will not be denigrated and dismissed by polygraph examiners.  That does not mean that such people have no worthwhile knowledge or experiences to relate.

One needn't be an expert in polygraph operation to conclude that if you tell the truth and don't hold back any information, and yet you still fail multiple polygraphs, the polygraph is not an accurate method of determining truth or deception.  However, any such anectdotal evidence is virtually always dismissed in the most peremptory fashion by polygraph "experts", who then go on to cite their own anectdotal evidence as proof that the polygraph is highly accurate in detecting deception.
