Behaviorally, poker and interrogations are very different

Zach Elwood, author of influential books on poker tells and host of the People Who Read People podcast, joins The Deductionist podcast for a wide-ranging conversation about what we can and can't learn from human behavior. Drawing on his years studying poker tells and consulting for high-stakes players, Zach explains why reading behavior in structured games like poker is fundamentally different from reading people in real-world situations like interrogations, negotiations, or everyday conversations. The discussion explores why nonverbal behaviors are almost always far less informative than what people say (and what they don’t say), why we can be drawn to overconfident behavior “experts" who promise certainty in uncertain situations, and how context and environment can dramatically change the meaning of behavior. We also discuss why some law enforcement professionals claim that understanding nonverbal behavior is hugely important in their work, while others claim it has close to zero impact. Sometimes, people are talking past each other, and thinking about entirely different aspects of behavior.
