People Who Read People: A Behavior and Psychology Podcast

In real or fictional criminal interrogation scenes, you've probably seen the approach where police barge in and confront the suspect with the evidence, trying to get them to crack and give a confession. In this talk, Maria Hartwig and Christian Cory explain why that doesn’t work well, and why a strategic use of evidence (SUE) approach, involving planning out the reveal of evidence, gets much better results. Maria is a well known researcher and trainer of criminal interviewing, and Christian is a 26 year law enforcement veteran. I talk to them about their and others' attempts to promote more science-based approaches to interviewing and interrogation. They are Co-Directors at the Aletheia Project (project-aletheia.org), which brings together researchers and law enforcement practitioners to improve interview techniques. We talk about their view that "old school" interrogations are built around a misguided "confession obsession," why bad ideas and exaggerated claims about nonverbel behavior and lie detection are so persistent and popular, and the downsides of lying to suspects about evidence. We talk about what the science really says about micro-expressions, and we explore why people seem so drawn to false, exaggerated ideas about reading behavior.

Zack Davies was a standout contestant on the popular reality TV show The Traitors (UK, season 2). The Traitors is what is called a social deduction game, similar to the games Werewolf and Mafia. In this talk we examine psychological factors and behavioral clues that can shape players' perceptions and decisions in this game. We discuss how friendships and rivalries can negatively affect people’s judgment. We talk about behavioral clues; for example, why it is that unusually expressive, exuberant behavior is a clue that someone is a Faithful (i.e., a “good guy”). We talk about social deduction game strategy, deception, group psychology, unconscious bias, and how to make tough judgments when there’s little actual information or evidence to go on. Zack shares behind-the-scenes stories from the show, including the intense stress of life in the castle, and a panic attack that never made it on TV. Whether you're a fan of The Traitors or just interested in human behavior, you’ll probably find a lot to like in this episode.

How do digital/open-source investigators uncover hidden truths and expose lies? World-renowned digital sleuth Craig Silverman shares important lessons he's learned from years spent exposing scammers, fake-news operators, fraud networks, and online deception. We discuss: the techniques investigators use to track anonymous people through seemingly insignificant clues; why stepping away from a case can be more productive than obsessively chasing leads; and how confirmation bias can derail even experienced investigators. Craig recounts the story of how he identified the anonymous creator behind the influential fake-news site True Pundit, along with other investigations that uncovered sophisticated fraud schemes that made millions of dollars. We also explore the modern explosion of misinformation, fake credibility, and AI-generated deception, and why investigative skills are becoming an increasingly valuable skill—not just for journalists, but for anyone trying to make sense of today's confusing information landscape.

How much can we really learn from people's words and behavior—and where do we risk fooling ourselves? In this talk, former Secret Service agent and polygraph examiner Brad Beeler explores the practical realities of interrogations, deception detection, statement analysis, and reading people in high-stakes situations. We discuss why confirmation bias is such a threat to good investigations, why many popular body-language claims are overstated, and how investigators might make use of subtle behavioral clues without becoming wrongly overconfident in them. Brad shares stories from criminal investigations, explains how experienced interviewers think about truth and deception, and offers a polygraph examiner’s take on the controversial subject of polygraphs. We also talk about the importance of rapport-building and listening to what people are actually trying to communicate.
