This show will help you understand human behavior and psychology so you can better navigate your personal and professional life and better connect with people. The host Zachary Elwood, known for his Reading Poker Tells trilogy of books, talks with a wide range of guests who have unique real-world insights, including: law enforcement professionals, behavior and psychology researchers, sports analysts, visa officers, jury consultants, political researchers, mental health experts, and many more. What drives this show is the idea that truly understanding people requires patience, nuance, and a willingness to question simplistic ideas and assumptions. There are more than 200 episodes.

Can trained investigators really tell when someone is lying based on nonverbal reads? And if not, what should they be focusing on instead? I talk with Maria Hartwig, a leading researcher on deception and interviewing, and Christian Cory, a former homicide detective and investigations commander, about the growing movement toward science-based interviewing. They are Co-Directors at the Aletheia Project (project-aletheia.org), which brings together researchers and law enforcement practitioners to improve interview techniques. We discuss their view that traditional interrogation methods are built around a misguided “confession obsession,” why bad ideas and exaggerated claims about body language and lie detection are so persistent and popular, and how techniques like the Strategic Use of Evidence (SUE) can help investigators gather more reliable information. We discuss the work of Paul Ekman and Joe Navarro, what the science really says about micro-expressions, and we explore why people seem so drawn to false, exaggerated ideas about reading behavior.
