A recent book written by veteran CIA officers describes how deception can be identified by simple observational techniques. In Spy the Lie: Former CIA Officers Teach You How to Detect Deception, authors Philip Houston, Michael Floyd, and Susan Carnicero outline a number of verbal and visual behavioral clues that are demonstrated by people who lie in response to questioning. These proven techniques for recognizing deception can be easily applied to see that U.S. leaders have lied repeatedly about the attacks of 9/11.
The authors make clear that there are two important guidelines to employ when analyzing these verbal and visual clues. First, timing is important. Due to the fact that people think ten times faster than they speak, the behaviors are more important when the first one occurs within five seconds of the question. Secondly, when the behavioral clues occur in groups of two or more, called clusters, they are more indicative of deception on the part of the person being questioned. The more clues exhibited, the more clear the deception becomes.
Let’s take a look at some examples.
