During Defcon 2010, a talk was given on how to build a lie detector and "beat" it. I've been enthralled by the idea of lie detectors for some time. My curiosity has always been whether the simple notion of having a scientific manner of detecting deception is psycho-semantic enough to arouse certain deception "indicators" that can be picked up by the machine. In plain English, I'm curious to whether people fail these tests purely because they know a machine is actively looking for any signs of deception and there is no way to know what questions may be asked so they unconsciously allow themselves to be caught by it. If anyone has any ideas, feel free to shoot them my way.
