Since 2003, LSAT (Linguistic Statement Analysis Technique) has trained thousands of people in "Investigative Statement Analysis". ISA is a highly technical method that examines multiple elements of language. Focusing on research from the areas of psychology, cryptology, linguistics, and mathematics, the analyst reveals the trends in language that tell if the story is the product of memory (truth) or fabrication (deception).
The analyst is actually able to view the crime through the eyes of the author, adopting their thought process to discover evidence, activities, people and hidden information they tried to conceal from the reader.
Armed with the truth behind the story, the analyst strategizes their interrogation and uses the author's own words against them to trap the guilty person and compels them to confess.
The LSAT analyst uses our validated, researched technique to search the statement much like a crime scene. They locate "language evidence" that is associated with deception. The liar uses unique wording, phrasing, content, structure and quantities of information that reveal not only if they did it but also, when, why and how they did it.
