Actually, it is VERY hard to cheat on them. If is was easy, they wouldn’t be that effective. Polygraph is widely used in the intelligence community, it’s about time someone suggested it be used at higher levels.
very hard to cheat on, surely you jest. I know first hand, and many others who have cheated on lie detectors,. Al you need to know is how they work.
Another way to assess the responses to the polygraph test is to have 2 trained officials; one on either side in front of the one taking the test, watching the eye movements closely.
