Throughout history, there has been an intrinsic need for humans to detect deception in other humans. Developed in 1923, the polygraph machine was a tool designed to do just this. To date, there have been many improvements made to the basic polygraph instrument. This book outlines the instrumentation as well as the latest in questioning techniques and methods available to the professional interviewer to determine truth from deception. The book covers psychology and physiology, a history of polygraph with the advances of leading figures, question formulation, data analysis, legal implications and legal cases, and the author’s developed technique Integrated Zone Comparison Technique (IZCT).

Effective Interviewing and Interrogation Techniques believably answers the question, How do you know when someone is lying? It also provides a guide for interviewing probable suspects and interrogating likely perpetrators on techniques and tradecraft. This book covers topics about searching for truth and revealing lies. It presents forensic assessments based on psychophysiology, and assessments on the basis of non-verbal behavior. The book also covers interview and interrogation preparation, as well as question formulation. It discusses the Morgan Interview Theme Technique or MITT, and the Forensic Assessment Interview or FAINT. The book addresses techniques for interviewing children and the mentally challenged, and offers information about pre-employment interviews. It also explains how to understand aggressive behavior and how to deal with angry people. The 4th Edition adds several Chapters on how to ascertain maximum information from victims and witnesses. The book concludes by presenting future methods for searching for the truth. Law enforcement and security professionals, as well as prosecutors, criminal defense lawyers, and civil litigators will find this book invaluable.
