Word Cues as Truth Clues: Inductive Interviewing for Investigators

Advances in forensic technology confirm that traditional interviewing and interrogation techniques that rely on overly coercive tactics and clever psychological tricks can generate false confessions, alienate juries, or lead to premature termination of the interview due to emotional or legal shutdowns. The Inductive Interview System is designed and proven to overcome these pitfalls of other interviewing techniques and produce credible confessions that will withstand court scrutiny. The Inductive Interview System creates an environment conducive to full disclosure of the truth while overcoming reluctance to reveal evidence of guilt and exposing attempts at deception or suppression. This unique, non-linear, non-confrontational approach is significantly different, more reliable, and considerably more flexible than traditional “linear” approaches to forensic interviewing.

Ray Nash began his 40-year law enforcement career as a police dispatcher while he was still in high school. After a time as a patrolman and street supervisor, he was appointed Police Chief in Irmo, South Carolina at the tender age of 23. Later, he served as a Training Specialist with the Institute of Police Technology and Management (I.P.T.M.) at the University of North Florida, then returned to S.C. for his second tenure as a Police Chief, this time in Summerville.


In 1997, Ray began the first of his three terms as the elected Sheriff in Dorchester County, SC.
