How does someone make a living playing slot machines—and why would casinos let them? After joining professional gambler Chris Huang on a casino trip in Atlantic City, I talk with him about the unusual career of casino “advantage play” and how pro slot machine players capture the money left behind by other, less knowledgeable players. We explore why manufacturers create beatable machines, the psychological tricks that machine makers use to attract players, and the unethical actions some slot machine pros take to manipulate players into leaving profitable seats. Chris explains the risks pro slot machine players can encounter, how seemingly promising opportunities can turn into expensive mistakes, why a little knowledge can be dangerous, and what happens when you run out of cash in the middle of a long-term play. We also discuss online gambling “gurus” selling dubious claims of expertise, the secrecy and competition among slot professionals, and the appeal—and pressures—of making a living this way.

A talk with Andrew Thompson, a New York City-area private investigator and a researcher of criminal behavior and interrogation techniques. Andrew shares how he gets people talking while lacking the authority and command of a police badge, and what studying FBI crime cases and interrogations taught him about linguistic clues to deception in people’s stories. We also discuss his research into criminal personality categories and how that may be tied to linguistic patterns. We discuss how mistaking signs of anxiety for guilt or deception can send investigators down very wrong paths; and how aggressive questioning can contribute to false confessions and other negative outcomes. We discuss why appearing uninterested in an important revelation from someone can sometimes encourage them to reveal more, and other tips on influencing and manipulating people in order to achieve investigative results. And Andrew discusses how AI advances have affected the investigative industry. Hosted by Simplecast, an AdsWizz company.

On this podcast I sometimes explore the “behavior expert” industry. One thing I'm curious about is the value people say that they’ve received from “behavior expert” trainings and certifications. This is a talk with Gallia Winkler, a psychological coach and a behavioral student of Joe Navarro’s; she’s been certified in his Body Language Expert Program. I ask her about what drives her interest in nonverbal behavior, what value she believes she’s gotten from Navarro's teachings, and how those teachings have helped her in her personal and professional life.

A talk with former CIA officer Kent Clizbe about the exaggerated, irresponsible claims made by many self-described “behavior experts,” focusing especially on Paul Ekman, Joe Navarro, microexpressions, and attempts to detect deception from body language. We discuss why facial expressions and physical movements cannot be interpreted through a universal dictionary, how cultural and individual differences make behavioral judgments especially difficult, and why nervousness or discomfort is rarely meaningful evidence of guilt or deception in high-stakes situations. We examine the failed TSA SPOT program, the influence of shows like “Lie to Me” (which was loosely based on Paul Ekman’s work), and the lack of convincing real-world, high-stakes examples supporting “behavior expert” claims. We also explore how behavioral hunches can contribute to tunnel vision, false confessions, and wrongful convictions; why games like poker can offer a more constrained and useful setting for behavioral reads; and why the most actionable information in high-stakes situations almost always comes from what people say, what they leave out, and how their statements compare with known facts.

A talk with an Army Psychological Operations soldier about what military psy-op work really involves—and how different the reality is from many people's ideas about the nature of that work. We discuss his psy-op work in Afghanistan, why credibility and truth are usually much more persuasive and effective than deception, and fascinating historical operations involving surrender appeals, staged intelligence, and Vietnam’s eerie “ghost tapes.” We also explore the legal and ethical limits on influencing Americans, how social media has blurred those boundaries, how foreign influence campaigns exploit political polarization, and why “PSYOP” has become an all-purpose label for conspiracy theories. Finally, we examine the red flags that can help you identify self-proclaimed-but-deceptive military-persuasion experts (like Chase Hughes) who fabricate and exaggerate their credentials and experience to sell their psychology- and behavior-focused training and products.

Can machines spot a lie better than we can? I talk with psychology researcher Bennett Kleinberg, whose work brings together psychology, machine learning, natural-language processing, and deception detection. We explore why humans are bad at identifying lies, which verbal clues may reveal deception—and why nervousness is often misleading. Bennett explains how liars use detail and how level of detail can be a clue to deception, the fact that deception usually involves a good amount of truth in the mix and what that means, and what happens when human judgment is combined with AI. We also discuss the risks of the mysterious black-box nature of some machine learning systems, and how smarter, research-informed interviewing techniques could transform criminal investigations.

Former Scientologist Chris Shelton spent thousands of hours using the e-meter to "audit" fellow members of the Church—but what does the device actually measure, and why do Scientologists trust it as an infallible guide to the truth? Chris takes us inside a typical auditing session, explaining the personal questions auditors ask, the needle movements they watch for, and what they believe those reactions reveal. We compare the e-meter with the polygraph, explore how relentless questioning can produce false memories and confessions, and examine how auditors can sincerely believe they are helping even when their methods become coercive or abusive. If you’re interested in Scientology, interrogation, or behavior reading, this is a fascinating look at how a simple machine can acquire enormous power through belief.

In a 2014 deception detection study, Pete Blair made 33 judgments—and got all 33 right. That paper was titled “Expertise in deception detection involves actively prompting diagnostic information rather than passive behavioral observation.” I ask Pete about what the factors were in him getting 100% accuracy in that study, and we talk about the interplay between verbal and nonverbal behavior. Pete talks about the importance of context and domain knowledge in making high-confidence judgments, and he discusses how such insights will sometimes be based on aspects that we aren’t consciously aware of.

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. Hosted by Simplecast, an AdsWizz company.

Polygraphs are a controversial tool in criminal investigations: critics argue they're too unreliable to trust, while proponents say that, even if they’re not perfect, they nonetheless can play a valuable role in helping uncover the truth. I talk with veteran polygraph examiner David Goldberg (executiveprotectiongrp.com), who has conducted more than 20,000 examinations over a 30-year career and who believes that, in the hands of a highly skilled examiner, polygraphs are far more accurate than most people realize. We discuss why he thinks innocent people should see nothing to fear when taking a polygraph, how experienced examiners distinguish deception from nervousness, how hiring processes use polygraphs, and why he sees interviewer skill—not the technology—as the biggest factor in accuracy. David talks about the granular details of how a polygraph examination is conducted, and the strategies he uses. Along the way, we explore the broader question that underlies so many debates about the polygraph and other uses of behavior analysis: when can information that's less than 100% reliable still be useful for making important decisions?

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. Hosted by Simplecast, an AdsWizz company.

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. Hosted by Simplecast, an AdsWizz company.

What if some job applicants aren’t actually trying to get jobs — but are instead trying to infiltrate companies? Dani Tepedjiyska, who works with the recruitment firm Michael Page, describes a strange and growing world of fake resumes, organized applicant networks, AI-assisted interviews, and suspicious staffing firms that may be helping fraudulent actors gain access to banks and other financial institutions. We talk about the real-world signs she’s seen while interviewing deceptive candidates — from people secretly receiving answers during interviews to applicants who suddenly crack under simple follow-up questions. We also explore how AI tools are making this kind of fraud much easier, why remote work creates new vulnerabilities, and how some infiltrators may be playing a very long game. Along the way, Dani shares practical insights for job seekers about how recruiters analyze applicant resumes and behavior, and tips on optimal LinkedIn strategies.
