Good Liars

I recently read an article about lying, and according to Psychology Professor Caroline Keating, good liars are ultimately good actors. Her advice on how to lie convincingly is to "rehearse" in order to reduce anxiety. "Good lying, like good acting, is an art that requires a plausible story, well-practiced."

This is absolutely true, which is why an investigator should also be well-practiced and well-trained. An individual who intends to be deceptive will likely plan ahead as to what they are going to say and what they are not going to say. This often appears as a lot of information right up front, but as you progress through the interview with appropriate probing questions, no further information develops. The reason for this is that liars tell their "story" right up front and when probed for further information, nothing is there since they are not relying on their memory because their "story" is just that, a "story" and not a memory.

This is contrary to truthful people who are recalling information from their memory. Quite often a truthful person provides information at the beginning of the interview, and if you probe their story correctly, like with Cognitive Interview prompts, you will get additional information and detail because they are accessing memory, and memory links and traces are accessed leading to additonal information.

So, with proper training an astute interviewer can win at the game of deception because no matter how much planning a liar does, they can't possibly plan for every question! 


Our primary purpose is to enhance the investigator's ability to develop rapport, facilitate communication, extract more accurate information, detect deception and obtain the TRUTH from every investigative inquiry.
