ABSTRACT

In this initial chapter, we highlight the wide variety of contexts within which deception is a significant factor and the relevance for forensic professionals. Proto-theory, history, and early work in deception are discussed along with guidelines for conducting research and the vexing problems in using DSM-5 and ICD-10-CM to diagnose deception-relevant conditions, such as malingering, antisocial personality disorder, and factitious disorders. We discuss the attempts to address deception in the ethical codes of the APA and the AMA. Deception in academic settings, police interrogation, health-related research to include concealment of HIV-status, and virtually all forms of violence to others are discussed.
