Ep171 "Why Do Some Urges Feel Irresistible?" with Paige Gordon
Ep171 "Why Do Some Urges Feel Irresistible?" with Paige Gordon Sep 14, 2026 2789 Why do two people facing the same choice feel different urges? How much effort hides behind resisting a cookie? Why can the brain keep wanting something long after pleasure fades? Can a molecule crank down the volume of your internal radio? Does a biological understanding of behavior reduce responsibility, or does it deepen compassion? And how would your life change if your loudest urge went quiet
Ep 170 "Will Mars Create a New Species of Human?" with Scott Solomon
Ep 170 "Will Mars Create a New Species of Human?" with Scott Solomon Sep 7, 2026 2931 What happens when we start birthing babies on Mars? Might a Martian human become unable to survive on Earth because of differences in microbes and gravity? How much of your body is shaped by the details of this planet? Will radiation accelerate human evolution on Mars? Could living on Mars eventually create a new species of human? Could Mars change the way humans dream? Would a Martian child find
Ep169 "What Is Claude Thinking But Not Saying?" with Jack Lindsey
Ep169 "What Is Claude Thinking But Not Saying?" with Jack Lindsey Aug 31, 2026 4869 Is AI thinking things it never says aloud? How would we know if a large language model were having a subjective experience? Is there a way to read the 'thoughts' of an LLM? Human brains seem to have a 'global workspace' -- what would it mean if we discovered that AI has something similar? Can you reach inside an LLM to change one of its 'thoughts'? Join Eagleman with Anthropic interpretabilit
Ep168 "Will it Someday Make Sense to Elect an AI President?"
Ep168 "Will it Someday Make Sense to Elect an AI President?" Aug 24, 2026 2765 Could there be a better form of government than the one we have now? As we enter an AI-powered world, when might we choose an AI leader? Will your grandchildren ever vote for a human president, who comes with a political party & the weaknesses of a human, or will they vote for a system that has a jaw-dropping capacity to extract patterns from vast rivers of data, simulate millions of possible
Ep167 "What Happens With Stone Age Brains + Godlike Tools?" with Steven Kotler
Ep167 "What Happens With Stone Age Brains + Godlike Tools?" with Steven Kotler Aug 17, 2026 2310 What happens when old brain circuitry collides with modern tech? Are we heading into an age of abundance, and can abundance create its own psychological problems? Do we need friction in our lives to become better humans? Could curiosity become the most important survival skill of the twenty-first century? What happens to your biological neural networks when artificial neural networks do your think
Ep166 "Could the Next Brain Interface Get Sprayed Up Your Nose?" with Tetiana Aleksandrova & Scott Meek
Ep166 "Could the Next Brain Interface Get Sprayed Up Your Nose?" with Tetiana Aleksandrova & Scott Meek Aug 10, 2026 2876 A brain computer interface (BCI) is any technology that allows you to connect your 3 pounds of wetware to a computer. But instead of implanting electrodes via neurosurgery, might the next revolution in BCIs come from something very small, like nanoparticles? Would this allow us to spy on millions (or billions) of neurons talking at once -- and could we do so without opening the
Ep165 "What's a Doom Loop & How Do You Escape It?" with Jonathan Downar
Ep165 "What's a Doom Loop & How Do You Escape It?" with Jonathan Downar Aug 3, 2026 3592 Have you ever spent hours with a thought cycling around in your head? What happens when the brain continuously worries, craves, or replays something without finding the exit? Where does the feeling of being “done” come from? Might depression, addiction, OCD, and PTSD all share the same problem? Is mental freedom just the ability to change states? Join Eagleman with neuroscientist
Ep164 "Why Do We Act Differently Around Different People?" With Claude Steele
Ep164 "Why Do We Act Differently Around Different People?" With Claude Steele Jul 27, 2026 4268 Does your identity and performance change in different situations? What does this have to do with wondering how you’re being judged? What if polarization grows from uncertainty more than hatred? Might social uncertainty be more common than prejudice? Why do strangers become enemies so easily? Can we engineer more trust into society? Today Eagleman sits down with Stanford social psycholo
Ep163 "How Quickly Does AI Become Smarter Than Humanity?" with Ben Goertzel
Ep163 "How Quickly Does AI Become Smarter Than Humanity?" with Ben Goertzel Jul 20, 2026 4169 What is artificial general intelligence (AGI) and how close are we to getting there? What defines the next step, called artificial superintelligence (ASI), and why might the gap between those two be so dangerous? When machines become smarter than us, what roles are left for humanity? Should we think of AI as software, or as something we’re raising like a child? Will tomorrow’s AI
Ep162 "What Does Medicine Look Like in Ten Years?" with Jeanne Loring
Ep162 "What Does Medicine Look Like in Ten Years?" with Jeanne Loring Jul 13, 2026 2025 For all of medical history, we’ve tried to persuade sick cells to behave better. What if instead we just swapped them out? Can we insert new brain cells grown from your own skin cells? And what does any of this have to do with sending one’s own cells into space, or rescuing animals on the very brink of extinction? Today we talk with stem cell biologist Jeanne Loring about the
Ep161 "What Do Ancient Brains and Future AIs Have in Common?" with Read Montague
Ep161 "What Do Ancient Brains and Future AIs Have in Common?" with Read Montague Jul 6, 2026 3802 What do honeybee brains have in common with human brains -- and with the AI that beat the world's best Go player? What simple algorithm has been hiding inside brains for 100s of millions of years? When babies throw food from a high chair again and again, are they being mischievous or are they running physics experiments? And what does any of this have to do with whether dopamine is more than a ple
Ep160 "Do You Really Have a Self?" with Sam Harris
Ep160 "Do You Really Have a Self?" with Sam Harris Jun 29, 2026 3996 re you the author of your thoughts or just their witness? Do we simply watch our thoughts like we watch unfolding dream plots? What if the most familiar thing you experience — yourself — isn’t really there? If that’s the case, why does the experience of the self feel so solid that it often takes a lifetime to notice something strange? Why would evolution invent the feeling
