Evaluating Truthfulness using Nonverbal Behavior

The ability to evaluate truthfulness and assess credibility is a crucial skill for many professionals whose jobs require interviews, interrogations, and information collection and reaction elicitation of others. The workshop covers topics including why people lie and why some lies succeed and others fail. We introduce participants to different techniques for perpetrating lies. We also compare accurate evaluations of demeanor with physiological measures.

Participants improve their individual abilities to make such judgments by focusing on the world of nonverbal behaviors evaluated in context against verbal output. Finally, we guide participants through a hypothesis-testing approach at thinking critically about how such evaluations are made as well as learning the scientific bases of some aspects of nonverbal clues to deceit.

“He was one of the most impressive speakers I have ever seen/heard. Interesting, intelligent, engaging and informative.”

Participants learn how to:

  • Improve skills in reading emotions and other nonverbal behaviors
  • Improve their ability to spot clues to potential deception via nonverbal behaviors. Participants learn which nonverbal behaviors have been scientifically proven to be associated with truthfulness and deception and which have not (yet remain as stereotypic myths about clues to deceit)

We provide participants an in-depth understanding of the nature and function of emotion and cognition when telling lies and truth. Participants learn how lies “leak out” – primarily through the face and involuntary microexpressions – and how to detect these signs of leakage through multiple channels of nonverbal behaviors. The workshop includes in-depth video review and practice of live lies and truth telling, discussions, role-play and simulations of how to use these skills in contexts relevant to the participants.
