According to the book description of Don’t Be Deceived it "was published in 2012 and discusses the only three ways you can tell if someone is lying without the aid of a machine. The first method involves analyzing how a person phrases his statement using the Statement Analysis® techniques.

The second method involves observing a person’s non-verbal gestures. Telling a lie can create stress that will surface in the form of a body movement.

The third method is handwriting analysis. A person’s writing traits can give us insight as to whether he is a secretive person.

An examination of all three of these lie detecting methods makes Don’t Be Deceived the definitive book on detecting deception."
