  • Lie Detection vs Investigative Interviewing: The Truth
    May 29 2026

    Lie detection has been the wrong goal all along. Mark Anderson spent decades in law enforcement, and his conclusion is blunt: the mindset you carry into an interview matters more than any signal you think you're reading off someone's face.
    In this episode:

    Why curiosity over certainty is an operational principle, not a motivational slogan, and what it actually changes in practice

    The lie detection problem: why watching for behavioural signals produces confirmation bias rather than accurate reads

    How behavioural observation functions as question fuel rather than a truth-or-deception verdict, and why that distinction matters operationally

    The power and control dynamic in investigative interviews, and why maintaining control by giving it up is the move most interviewers won't make

    Bob Pointer on talking to the mask: why addressing who the person wants to be seen as is more productive than trying to strip it away

    System 1 vs System 2 thinking in the interview room, and how pressure to act on instinct produces the worst outcomes at the highest stakes

    Why red-teaming your own interview mindset reduces confirmation bias more reliably than technique training alone

  • Disclaimers and Critical Thinking With Kent Axell
    May 29 2026

    Most people think critical thinking means finding the right answer faster. Kent Axell has spent a career proving it means knowing exactly which doors you're closing behind yourself, and why that distinction changes everything from a Las Vegas stage to a jury room.
    In this episode:

    Why magicians develop critical thinking skills that investigators and analysts rarely get trained in

    The assumption gradient: where useful belief ends and self-deception begins

    Why "I don't know" is a more powerful position than certainty, and how the skeptic community gets this wrong

    Disclaimers in mentalism, what they actually communicate, and why technically honest is still functionally deceptive

    The Chris Voss story: what happened when a master negotiator watched a mentalism show and still ended up in the wrong box

    Why "body language" as a term sets people up to believe in something that does not work the way they think

    Vincent Denault's research on how public misconceptions about behavioural reading are actively influencing police training, jury evaluation, and interrogation

    If the gap between what people believe they can read and what the evidence actually supports concerns you, this episode goes there.

  • What's Actually Driving You (And Why You're Probably Wrong About It) w/Pete Rushmer
    May 22 2026

    Pete Rushmore built a business, hit the metrics that were supposed to mean something, and felt nothing. Not because he failed. Because the vision he was chasing was answering a question he'd never actually asked.

    This episode follows the performance trifecta he developed out of that realisation: direction, skills, energy, and why energy is the foundation even though it's the last thing anyone looks at.

    Motivational mapping, self-determination theory, the gap between what people say drives them and what actually does. Bob and Ben both have opinions. Pete handles them graciously.
