Those behavioral analysis techniques (which, by the way, are not scientifically unchallenged) proport to detect "deception." So we're still caught up in the logic-loop here: what the individual believesto be the truth, whether or not he is speaking consistently with his belief or deceptively, and what are actual facts in the matter... all balled up in the same can of worms.
