Interrogation trainer shares what really works (and why "reading people" doesn't)

Author: Zachary Elwood May 5, 2026 Duration: 1:07:45
Many people think police interrogations often involve reading body language and catching “tells” of deception. Interrogation trainer Mark Anderson explains how much of what’s taught about using nonverbal behavior in high-stakes interviews is based on myth, not science—and how a faulty focus on “reading people” can actually damage interviews. We dig into why stress behaviors don’t signal guilt, how confirmation bias warps investigations, and why “reading people” is far less useful than most believe. Instead, Mark lays out what actually works: deep listening, better questioning, managing conversations, and building real rapport—even with people who’ve done serious harm. Along the way, he shares stories from his career that show how empathy and curiosity can unlock information in surprising ways. If you’re interested in psychology, communication, or the reality behind interrogations, this episode might challenge some of your basic assumptions. Learn more about your ad choices.

Ever wonder what a professional poker player notices about your tells, or how an FBI interrogator knows when someone’s lying? People Who Read People: A Behavior and Psychology Podcast digs into these questions through conversations with a fascinating array of experts. Host Zachary Elwood sits down with people whose jobs depend on accurately interpreting others-from jury consultants and behavior researchers to sports analysts and deception detection professionals. Each episode pulls back the curtain on the practical frameworks these individuals use to make sense of why we act the way we do, moving beyond textbook theory into the messy, applied reality of human interaction. With over 135 episodes in the archive, this podcast offers a deep and varied library exploring the subtle signals, hidden motivations, and cognitive patterns that drive our daily lives. You’ll hear specific stories and case studies that reveal how understanding behavior plays out in high-stakes courtrooms, strategic games, and everyday relationships. It’s for anyone curious about the mechanics of social dynamics, self-awareness, and the art of observation. Elwood’s grounded, interview-led approach makes complex psychological concepts accessible and immediately relevant, building a resource that feels both insightful and genuinely useful.
