The Theory of Truth and Deception

The Theory of Truth and Deception

Note: This course was originally a module of the 'Investigative Communication' course that was first released in October 2004. 'Investigative Communication' has now been re-organized into three separate short courses: The Theory of Truth and Deception, The Theory of Communication and Memory, and Interviewing.

Certain aspects of effective communication, such as developing skills for detecting when someone is being truthful or deceptive, are often omitted during training. It is a fact that people lie to the police and it cannot be assumed that every person who reports a crime, or is being interviewed, is being totally honest. Law enforcement officers must be both impartial and skilled at detecting deception.

Improving skills to differentiate between truth and deception requires recognition of the importance of communication, an understanding of basic interviewing concepts, and a desire to become a proficient investigator. With practice, the knowledge, skills, and attitudes needed to obtain information become more developed and the ability to read verbal, nonverbal, and paralinguistic indicators of deceit become enhanced.
