The Gap between Training and Research in the Detection of Deception

Abstract

Since the 1970s, more than 150,000 criminal investigators around the world have been trained in The Reid Technique of Interviewing and Interrogation. The Reid Technique contains a model of nonverbal behaviour that is purported to help investigators determine if a criminal suspect is giving truthful or deceptive answers in response to investigative questions. This paper discusses the existing research regarding nonverbal behaviour and how this behaviour coincides with the Reid model. Existing research provides only limited support for the model. Policy implications are discussed.
