Communication Rules & Active Listening

You now know how important it is that lie detection starts with rapport, which is used for establishing a baseline behavior. Baseline behavior is the reaction to a conversation under limited or no pressure. This means, while building rapport, be conscious of the prospect’s normal verbal, and nonverbal behaviors, including what they are saying and how they are saying it, like tone, pace, pitch, and volume. When lie detection is the goal, you will compare the behaviors during rapport to those exposed during your attempts to uncover a lie or hidden emotion.
