Possible Control, not sure.
Starts out this way--
Polyguy-"Have you ever taken something from any previous employer"
Me, "Yes, I took 2 pairs of sunglasses"
Polyguy-"How much was it worth?"
Me- 130.00.
Polyguy- "Besides what you have told me, have you ever taken anything from an employer worth over 130.00?"
Me. No.
What is that? Starts as control, but I think turns into relevant???
Is that possible?
This is a classic "control" question.
Despite the admission, the question does not turn into a relevant one as far as polygraph scoring technique.
Still, an admission like the one you describe above to any question--relevant or control--is likely to be disqualifying...
