This is a podcast about deciphering human behavior and understanding why people do the things they do. I, Zach Elwood, talk with people from a wide range of fields about how they make sense of human behavior and psychology. I’ve talked to jury consultants, interrogation professionals, behavior researchers, sports analysts, professional poker players, to name a few. There are more than 135 episodes, many of them quite good (although some say I’m biased). To learn more, go to PeopleWhoReadPeople.com.
Can you really tell who’s lying just by watching their body language? Are there any practical takeaways you can reliably and regularly get from studying nonverbal behavior in interrogation/interview settings? In this episode, I, Zach Elwood (author of some popular books on poker tells) talk to Chris Shelton, host of Speaking of Cults (speakingofcults.com). We take a hard look at the booming industry of alleged “body language experts,” behavior-based deception detection, and viral interrogation analysis (popular on YouTube and video platforms). We unpack why confident claims about blinks, posture, eye direction, and micro-movements are often misleading, how pseudoscience sneaks into true crime media and even law enforcement, and why innocent people can easily be anxious and seem suspicious under pressure. We discuss if there are realistic uses of body language in interrogation and other real-world settings, and what that might look like. If you’ve ever been persuaded by a YouTube body language “expert,” this conversation might change how you think about behavior.
