Quotehey cm cullen.. what do you mean by "maybe not the Fbi"..? why is the lie detector diferent with the fbi?
QuoteI agree with this part of Mr. Cullen's post though: "Using CMs at the wrong time and in the wrong manner can indeed backfire on you."

Correct, but you have to be prepared to explain your reaction on the "control". Just make sure it is not anything they could use to disqualify you. For example, admitting you stole a pen from work, not something major. The more they concentrate on you answers to a control questions, versus a relevant, the better.
Read the "lie behind the lie detector" it covers the use of CMs better than I could explain to you on this forum. Basically, the more you are disturbed and reactive on the control, versus the relevants, the greater you chances of passing. That and NOT letting them con you into admitting to anything they can distort and twist like their arrogant little minds!
And, as always, realize that a reaction on the machine does NOT mean deception no matter how much the examiner claims it does, but don't let on that you know that.

QuoteDuring the control questions of a polygraph , lets say they ask "Have you ever told a lie?" and you answer truthfully and say "yes" should you still use countermeasures when answering truthfully to control questions? Or should you lie on purpose and say no I never told a lie and then a use a countermeasure?
