The investigative interview process in the Reid Technique is called the Behavior Analysis Interview (BAI). The BAI consists of three types of questions: Initial Questions designed to develop biographical information, establish rapport, acclimate the subject to the interview environment, describe the investigative process and establish a behavioral baseline for the subject.

The second group of questions are the Investigative Questions, which are designed to develop the subject's story or version of events concerning the issue under investigation, his/her alibi during the time period in question, and the who, what, when, where, why and how of activities relevant to the issue under investigation. In previous Investigator Tips we discussed using open-ended questions to develop the subject's pure version of events, and how to use follow up questions to develop additional details from their initial account. (See March/April 2017 and May/June 2017 Investigator Tips: Using Open-ended Questions During the Investigative Interview Part 1, and Part 2).

The third type of questions are the Behavior Provoking Questions designed to elicit responses that can be evaluated as to the subject's credibility about their potential involvement in the issue under investigation. There have been in excess of 25 behavior provoking questions developed over the years but this Investigator Tip will only discuss four of them, and then illustrate their use in a case involving 2 subjects. Research has indicated that most truthful subjects answer the behavior provoking questions one way while deceptive subject's answer the same questions in a very different way.
