guy @ work who does lie detector tests says no!
i read once where, you can substitute questions in, like if they ask you, have you ever done drugs in the last 365 days? if your real answer was yes, quickly, in your mind, you ask yourself a question with a no answer and then say NO. forget where i read that and not sure if it evenm works but thought i would add it.
what did you do that requires you to lie on a lie detector test?
if its for a civil service job, and i know this from experience, dont lie. you will be given time to explain answers and lying is an immediate disqualifier.
