Deception in Court

Abstract

Different forms of deception can be applied to hide one's true intentions; this faking can take various forms, depending on the deceiver's aim(s): faking bad or faking good. Since 25-45% of behaviors are deceptive in a legal setting, detecting these efforts has become a priority. With this aim, the development of objective and effective tools has increased considerably. Starting with the first polygraph created by Vittorio Benussi in 1914 to nowadays through the implementation of Artificial Intelligence, we will explore the lie detection techniques that have followed over the years.
