Why people confess to crimes they didn’t commit
I've had a polygraph before while interviewing for a security clearance position. The questions they asked were pretty standard such as "are you a terrorist" and things. I could unequivocally answer the questions without a thought. But my polygraph took a couple hours and after a while in that room, being asked the same questions over and over, I honestly started to wonder if I was, somehow, a terrorist and they knew it but I didn't.
