Statement Analysis | Lying will Leave Evidence of Itself

It is impossible to lie perfectly and consistently. Lying will leave evidence of itself, which can be detected by the sensitive observer.

Statement Analysis is based on the premise that truthful stories exhibit certain consistent patterns and norms. When an account deviates significantly from these norms and patterns of truthfulness, the analyst will know that something is amiss at that point and will then investigate that area more closely for other signs of deception.

The purpose of it is to detect deception and to obtain information. Statement analysis is founded upon certain basic laws of human psychology, as well as on many years of experimental research and validation.The formal science of Statement Analysis began to take shape shortly after World War II, as structured techniques were developed to examine language usage. Those techniques were subsequently refined by several West German Psychologists and in 1954 it was mandated into the German legal system.

Further development on the adaptation of the original techniques was brought by American and Israeli investigators. In fact the "father" of modern Statement Analysis is Avinoam Sapir, an Israeli Rabbi whose extensively researched the field, applying his vast experience.
Statement Analysis techniques are today used by investigation and intelligence agencies as a very valid tool of "truth extraction".
