What really works in interrogations? (spoiler: it's not reading nonverbal behavior)

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.
