there is the very slim possibility that a truthful person might run into problems during an exam.

so are you accusing our original poster of lying or admitting that he is one of the slims? Or are you going to say you don't know which means you feel there is a 98% chance he is lying based on your assumptions about polygraph accuracy.

I am one of those slims. I was accused of being a drug dealer. If you stand back and look at this situation, its  kinda stupid to be accused of "breathing the wrong way". If the polygrpah is so accurate and the reactions subconcious and uncontrollable, why do they care how you breathe? Thats why its called junk science.

I remember being strapped in the chair. the procedure causes you to focus so much you find yourself very concious of your breathing and you automatically try to control it so as to remain calm. What a normal person considers a very natural thing to do to calm themselves, in the crazy world of polygraphy, this is considered an unethical, deceitful act and an insult to the examiner.
