How to Read Liars: Lie Detection

The Principles of Lie Detection

The process of detecting lies is found in Behavior Analysis. For the purpose of lie detection, behavior analysis is the study of the verbal and nonverbal cues of truthfulness. Since lie detection is a subset of reading people, it follows the same 4 principles as discussed in the previous article:

1. Establish a baseline behavior in your subject - make note of any deviation (this is THE KEY to lie detection!!)
2. Recognize the related clusters (patterns) of deception
3. Challenge and refine your assumptions through observation and questioning (continue w/ step 3 and 4 until you…)
4. Make your decision

Unlike what you may at first suspect, you are in fact first studying what truth looks and sounds like, not deception. After establishing how they behave when they’re being truthful (the baseline), you’ll be able to recognize any departure from this ‘normal’ state - which may be a lie!
