“If you have dealt with liars, even pathological ones who pass polygraph tests, you know the signs to look for. The liar blinks just before the end of the lie, or he keeps his eyelids stitched to his brow. He folds his arms on his chest, subconsciously concealing his deception. The voice becomes warm, a bit saccharine; sometimes there's an ethereal glow in the face. He repeats his statements unnecessarily and peppers his speech with adverbs and hyperbole. The first-person pronouns 'I,' 'me,' 'mine,' and 'myself' dominate his rhetoric. Conversely, the truth teller is laconic and seems bored with the discussion, not caring whether you get it right or not.”
