The Secret to Human Thought AI Will Never Understand
Elliot Murphy, a neuroscientist who studies language, cognition and the brain, offers a brisk tour of what makes human language unique. He explores innate language capacity, structural ambiguity and sentences humans grasp that AI misses. He examines language’s evolution, its role in deception and whether something beyond our current language could exist.

Spirits, Ghosts & The Strange New Neuroscience of Unseen Others | Ben Alderson-Day
Ben Alderson-Day is a cognitive scientist and author of the book Presence: The Strange Science and True Stories of the Unseen Other.In this podcast, we discuss the experience of sensing presences even in otherwise healthy people, why such experiences are more likely in extreme situations, how the brain constructs a sense of another being, how to think about the metaphysical status of spirits and ghost encounters, how this capacity shapes everyday reality, how AI might induce the feeling that someone is really there, and much more...Timestamps:00:00 The Strange Science of the Unseen Other 03:38 The Feeling of Presence of Beings06:15 The Third Man effect in extreme environments and survival situations11:46 The psychological function of presence capacity 18:46 Disrupting presence with the "presence robot"22:20 Are Spirits and Ghosts Real?27:04 Presence as an underlying component of everyday cognition31:28 Representing others and virtual social cognition35:59 The role of stereotypes and generalized models38:35 Anthropomorphism and presence in interactions with large language models42:28 Clinical implications and future research on AI and psychosisFind Ben:•Presence: The Strange Science of the Unseen Other •Reader Bank — https://readabank.org•Hearing the Voice — 10-year project at Durham University (funded by the Wellcome Trust)•Discovery Research PlatformFind Jack:• Youtube: https://youtu.be/LDAVqatEWTk• X: https://twitter.com/jack_roycroft• Substack: https://substack.com/@jackroycroftsherry?utm_campaign=profile&utm_medium=profile-page

The Quantum Physics of Retrocausality, Precognition & Synchronicity
Physicist Chris Fields recently gave a talk on retrocausality and non-causal information flow in physics, and how these concepts help us understand precognition and potential retrocausal effects in psychology experiments. I wanted to explore this further.What does physics say about whether time can flow backwards? How are physicists thinking about spacetime, identity, and memory differently than they did in the past? And what can the physics of retrocausality tell us about precognition experiments in psychology and strange cases of synchronicity in humans?Timestamps:00:00 Time Can Flow Backwards (in theory)02:25 Entropy & the Observer's Role in Time 04:10 Entropy and the Arrow of Time08:00 Time and the Big Bang14:00 What Actually is Time?

The Hidden Intelligence within Evolution, Matter & The Universe | Dr. Richard Watson
Dr. Richard Watson, biologist and computer scientist exploring cognition in life and matter. He debates limits of standard natural selection and why major transitions like multicellularity are puzzling. He describes learning and memory outside brains, how networks and ecosystems can encode information, and how cognition might predate life and shape evolution.

Beyond a Black Hole is a Big Bang - Julian Gough
What if the Big Bang was actually the other side of a black hole in a previous parent universe? Irish writer-turned-cosmologist Julian Gough and I discuss.In this podcast, learn about: where the term "black hole" came from, how black holes and the Big Bang seem suspiciously like one another, why our universe looks like it comes from an evolved history of parent universes, how universes can evolve their parameters of physics through offspring universes (from their black holes), how cosmological evolution through black holes explains the complexity of the early universe, the nature of dark matter, why the universe could be purposeful, and much more...Timestamps:00:00 The Birth of Universes from Black Holes03:54 Could universes actually emerge out of black holes?05:38 How this idea explains the complexity of our cosmos09:05 What happens at the singularity of a black hole?11:40 Three-Stage Cosmological Natural Selection15:03 The Mechanism of Black Hole Production17:59 Moral Implications of Creating Universes20:54 The Future of Black Hole Research31:55 The Evolution of Black Holes and Stars35:11 Exaptation: Evolution's Ingenious Adaptation39:05 The Chemistry of Life and Stellar Evolution40:55 The Role of Supermassive Black Holes in Galaxy Formation51:13 Spiral Galaxies: A New Perspective01:04:14 The Universe as an Evolving Organism01:05:45 Galaxy Formation and Supermassive Black Holes01:08:36 Critique of Mainstream Cosmology01:10:13 The Sociological Implications of Cosmology01:11:41 Evolutionary History of Electrons01:14:37 Structure in the Universe: Past vs Present01:17:03 Purpose in the Universe01:19:21 Dark Matter and Self-Organizing Systems01:20:55 Interacting with Parent Universes01:24:11 The Future of Cosmological Theories01:28:15 Creating a New Field of StudyFind Julian:• Substack: https://theeggandtherock.com/• Blowtorch Theory: A New Model for Structure Formation in the Universe: https://theeggandtherock.com/p/the-blowtorch-theory-a-new-model• Website: https://www.juliangough.com/Find Jack: • Spotify: https://open.spotify.com/show/0DGVMa1qAI1huc87xNDrgy?si=62c281d9e8274694• X: https://twitter.com/jack_roycroft• Substack: https://substack.com/@jackroycroftsherry?utm_campaign=profile&utm_medium=profile-page

The Strange Experiment that Reimagines Mind & Cognition (Mike Levin Lab) - Adam J. Goldstein
Adam J. Goldstein is a cognitive scientist and entrepreneur working in the field of diverse intelligence.Is cognition just a brain thing? Recent evidence suggests that everything from cells to worms to slime moulds can be cognitive. In this episode, we go a step further and look at apparent problem-solving & cognition in simple computer algorithms. Might there be more to even basic algorithms than we think? And what could this reveal about the nature of intelligence, matter, and the universe?Timestamps: 00:00 Unexpected Behaviour in Sorting Algorithms06:05 What do Algorithms "Know"?08:29 Philosophical Perspectives on Algorithms11:33 Free Energy Principle and Its Implications14:39 Understanding Cancer Through Algorithms17:31 The Role of Algorithms in Human Behavior20:31 The Interplay of Algorithms and DNA23:21 Metacognition and Human Uniqueness26:28 AI and Cooperative Dynamics29:29 Michael Levin's Artificial Organisms 31:59 Algorithms vs. DNA in BiologySORTING ALGORITHMS PAPER DISCUSSED:• Sorting Algorithms paper: https://journals.sagepub.com/doi/10.1177/10597123241269740FIND ADAM• X: @adamjgoldstein• Read more: softmax.com/inspiration• Watch more: Friston, Levin, Goldstein talk on algorithms & Free Energy Principle: https://www.youtube.com/watch?v=ApVWEn-3vG4FIND JACK• Spotify: https://open.spotify.com/show/0DGVMa1qAI1huc87xNDrgy?si=62c281d9e8274694• X: https://twitter.com/jack_roycroft• Substack: https://substack.com/@jackroycroftsherry?utm_campaign=profile&utm_medium=profile-page
