A private investigator's tips on reading and manipulating people

A talk with Andrew Thompson, a New York City-area private investigator and a researcher of criminal behavior. Andrew shares how he gets people talking while lacking the authority and command of a police badge, and what studying FBI crime cases and interrogations taught him about linguistic clues to deception in people’s stories. We also discuss his research into criminal psychological personality categories and how that may be tied to linguistic patterns. We discuss how mistaking signs of anxiety for guilt or deception can send investigators down very wrong paths; and how aggressive questioning can contribute to false confessions and other negative outcomes. We discuss why appearing uninterested in an important revelation from someone can sometimes encourage them to reveal more, and other tips on influencing and manipulating people in order to achieve investigative results. And Andrew discusses how AI advances have affected the investigative industry.
