ask open-ended questions in which you obtain those all-important specific pieces of information. As the authors conclude, “Verbal content is more diagnostic than nonverbal behavior” (p. 7). When you get into the questioning itself, you can up the ante further by draining those all-important cognitive resources that the liar needs to try to hide the truth. You might start, if you want to be chatty about it, with informal non-event related questions, but then get right into those details and don't let up.
