When attempting to elicit an admission or confession, CIA polygraphers and adjudicators will make you think they know more about you and your private life than you think you know. It is all a mind game. The goal is to get you to make an admission because they allegedly already know whatever it is that you are withholding from them when, in fact, they don’t. That is the whole point of the polygraph: to break down the examinee and get them to disclose what they do not know about you and your private life based on the background investigation. They are trying to disqualify you based on the admissions that come out of your own mouth. They will also employ the false evidence technique, where they might bring in a stack of papers to intimidate you into thinking they have so much evidence against you that you might as well confess. They will say they already know what you did, and we have the evidence right here. This is another tactic they use to scare you into making an admission. Don't fall for it.
