  • A World Without Scarcity | Steven Kotler
    May 6 2026

    What happens to human beings in a world without scarcity? If all our needs were met, would we actually be better off? Will technological progress lead to utopia or collapse?


    Humans are living through massive improvements in material conditions. More people have access to food, energy, and technology than ever before. Steven Kotler examines what this kind of abundance does to us. It may support a more comfortable life, but it can also erode the conditions that sustain a sense of purpose.


    We also discuss how attention and identity are being affected by technological progress. As AI systems take on more optimization and decision-making, the role of human thought may change, raising questions about what remains distinctly human in how we engage with the world.

  • Living with Adversity | David Benatar
    May 6 2026

    What does it mean to live with adversity? How ought we respond to the suffering of others? How can we adapt to hardship?


    Adversity is a universal experience. Nearly everyone, at some point, faces physical, psychological, or social challenges, and yet suffering often goes unnoticed.


    David Benatar joins us to discuss these questions on the human condition, provoked by his book 'Living with Adversity,' a collection of personal accounts of suffering.

  • Risky Storytelling | Kevin Allison
    May 6 2026

    Kevin Allison, creator of the RISK! podcast, recounts a high school prank at an all-boys Jesuit school in 1986. After a crush teased him by repeatedly spitting on him, Kevin later mailed him a sealed container of feces labeled “enjoy the cookies.”


    In retelling the story, Kevin considers how the prank mixes humiliation and a possible form of intimacy, situated within his experience of growing up gay under Catholic doctrine. For Kevin, telling such stories has become an opportunity for self-reflection.


    Beyond this, Kevin argues that sharing what is usually considered “unmentionable” can create a distinct form of connection: moments of vulnerability tend to draw listeners in rather than push them away. Thus, the points of greatest risk are often where an audience leans in most.

    [12:49] Why the "Unmentionable" Matters

  • Free Speech, Hate Speech, and Mental Health | Chloe Carmichael
    Mar 22 2026

    Clinical psychologist Chloe Carmichael, author of "Can I Say That?," examines how free expression relates to psychological well-being and social trust. Carmichael argues that suppressing disagreement drives resentment and misperception, rather than resolving conflict. She also scrutinizes the role of safe spaces, the spread of therapeutic language, and what limits on speech might be justified in public versus private life.

  • The Nature of the Sexes | Tomás Bogardus (with Stephen Kershnar)
    Feb 22 2026

    Tomás Bogardus joins to discuss his book "The Nature of the Sexes" and argues for a reproductive-functional account of biological sex. According to Bogardus, males and females are defined by the reproductive function their bodies are structured to perform: producing sperm or eggs. Even when that function is not realized and no sperm or eggs are produced, a person’s sex remains the same, because it is grounded in biological organization. To defend this view, Bogardus considers intersex and DSD cases, critiques contextualist accounts that treat sex as domain-dependent, and argues for a unified meaning of “male” and “female.” The conversation later turns to whether sex is essential or changeable, as well as debates about pronouns, sports, and medical interventions for minors.

  • God Is Not Praiseworthy | Stephen Kershnar and Nathan Bray
    Feb 9 2026

    Brain in a Vat is back from hiatus with a deep dive into the philosophy of religion. Stephen Kershnar and Nathan Bray join us to ask whether God can be morally responsible and whether worship makes sense if God could not have done otherwise.


    The discussion begins with a thought experiment about gratitude and worship. If worship expresses praise for morally responsible action, can a perfectly good God deserve it at all? Kershnar and Bray argue that divine perfection may undermine responsibility rather than secure it.


    From there, Kershnar and Bray explore compulsion, omnibenevolence, and free will. Along the way, we discuss moral saints, chess computers, Frankfurt-style cases, Patty Hearst, and the costs these arguments impose on traditional theism.


    We would love to hear your thoughts. Is worship grounded in gratitude, awe, or something else entirely? And does God need moral responsibility to be worthy of it?

  • Facial Distortions and Prosopometamorphopsia | Brad Duchaine (Rebroadcast)
    Nov 9 2025

    In this special episode of Brain in a Vat, Brad Duchaine from the Psychological and Brain Sciences Department at Dartmouth discusses prosopometamorphopsia (PMO) – a condition where individuals see distorted faces.


    The episode explores various manifestations of PMO, including seeing demonic features, dragons, or entirely different faces, and distinguishes it from prosopagnosia (face blindness). It delves into the neurological basis of PMO, touching upon structural and functional differences in the brains of those affected.


    We discuss the significant impact PMO and prosopagnosia have on individuals' social interactions and quality of life, as well as potential management techniques such as using glasses or colored lights to reduce distortions.
