ABSTRACT
There are two basic ways to evaluate the accuracy of information in any given investigative situation: the analysis and comparison of factual evidence or information, and the behavioral assessment of the person who is the source of the information. Every investigator who questions a person about procedures that were followed, the sequence of events on a given day, the reasons why an action was executed in a particular manner, etc., evaluates the behavior displayed by that person and draws conclusions from it as to that person’s truthfulness or deception. These conclusions are usually reached by a comparison of the information provided against a subconscious assessment of the behavior displayed by the source.
