CONTROL VS. RELEVANT

[Paul]

I was wondering how one can differentiate between a control and a relevant question..also what are some good drug related relevants and controls...this topic concerns me as I've never used any form of illegal drug, I assume the polygrapher will automatically take for a liar, I'll be damned if I admit to using them just for the sake of it...can anyone help me.. thanks in advance

Paul,

The question of how to recognize relevant vs. "control" questions is addressed at length in Chapter 3 of The Lie Behind the Lie Detector. If this chapter leaves you with further questions, please don't hesitate to post!
