other guideline has to do with clusters of deceptive behavior. A cluster is defined simply as any combination of two or more deceptive indicators, which, you’ll remember, can be either verbal or nonverbal. So a cluster might be one verbal and one nonverbal, or two nonverbals, or two verbals and one nonverbal, and so on. What do you do if there’s just a single deceptive behavior in response to the stimulus? You ignore it.
