Culture, from birth to death (metal)
Culture can be a little hard to wrap our minds around. It's seemingly everywhere, enveloping us—but where is it exactly? What are its core properties? How does culture change? Why does it change? What tools and techniques should we be using to understand its vagaries? How can we illuminate this living, breathing, omnipresent, amorphous thing? My guest today is Dr. Jacob Foster. Jacob is a Professor of Informatics and Cognitive Science at Indiana University – Bloomington; he's also an External Professor at the Santa Fe Institute. For more than a decade now, Jacob has been bringing together different disciplinary strands to develop a theory of culture and a toolkit for studying it. Here, Jacob and I talk about what culture is—and whether cultural ideas are, in an important sense, alive. We discuss Jacob's path through physics to complexity science to sociology and to cognitive science. We talk about the nature and value of computational thinking. We dig into Jacob's framework for thinking about culture as a set of chains that weave from mind to world and back, across time and space. We dig into a colossal new paper of Jacob's in which he and his co-authors characterize the dynamics of culture through the case of metal music—a genre that has been evolving, splintering, growing, and withering for more than 50 years. Along the way, Jacob and I touch on metaphors for culture as dark matter, as amphibian, as a set of companion species, as living vines on a human trellis. We touch on foxes and hedgehogs; personal culture and private culture; how to be a wizard; ecological carrying capacity and cultural carrying; schismogenesis; the ideas of Sperber, Heidegger, Jung, and Culianu; ideal objects and morphodynamics; and how viewing culture as alive give us a different stance toward the dead. This not my first chat with Jacob. As you'll hear, we overlapped in our undergraduate years, also in our postdoc years, and since 2018 have worked together at the Diverse Intelligences Summer Institute or DISI—which, of course, is the sponsor and incubator of this very podcast. Jacob and his wife Dr. Erica Cartmill founded DISI and are the current directors. I always have fun talking to Jacob—I always learn a bunch from him. And so I think you'll enjoy this one, friends.

Island of the tool users
Tool use is rare in the animal kingdom—but maybe not as rare as we once thought. Since Jane Goodall famously observed a chimpanzee fishing for termites, many new examples of animals using tools have come to light. Birds using sticks to forage for grubs. Sea otters using rocks to smash open mussels. Digger wasps using stones to close off their burrows. But as these examples mount, so do the scientific questions. What is tool use, really? What different forms does it take? Does it always imply a high degree of intelligence? And perhaps the biggest question of all: Why do some creatures use tools while so many others don't? My guest today is Dr. Alice Auersperg. Alice is a cognitive biologist at the University of Veterinary Medicine in Vienna. She and her lab study innovation, technical cognition, and tool use in animals—especially in a species of parrot known as the Goffin's cockatoo. Here, Alice and I talk about her lab's recent work with a certain remarkable cow. We discuss the wide variation in definitions of tool use across studies, and why some kinds of tool use are perhaps more impressive than others. We walk through some of her lab's most striking findings about tool use in the Goffin's cockatoo: for example, the finding that these birds don't just use tools but also make them—and can make the same tool out of different materials; the finding that they learn to use tools from others; and the finding that they recognize in some way the value of tools. We dig into some Alice's ideas about the big picture—why certain species use tools, and why so many tool users seem to live on islands. Along the way, Alice and I talk about whether tool use in birds is fundamentally different from tool use in primates; we talk about play and boldness; the allure of the sea mango; intrinsic motivation to combine objects; why tool use differs in captivity, at least in Great Apes; and why Goffin's cockatoos like to dunk their noodles in blueberry soy yogurt. Before we get to it, a brief announcement. We've been steadily expanding the ways you can engage with us. We recently revived our newsletter, in the form of a Substack. And our episodes are now up on YouTube (albeit in audio-only format, for the time being). And of course you can still find us on Spotify, LinkedIn, and on Bluesky.

Cognitive offloading and its consequences
For thousands of years—maybe for as long as we've been human—we've offloaded our thinking. We've counted on our fingers. We've carved tallies into bone. We've invented a long series of tools to help us reason, remember, and manage information—tools like abacuses, calendars, writing systems, calculators, smartphones, and many, many more. So cognitive offloading is hardly new—but the questions around it seem newly urgent. As cognitive technologies accumulate, as opportunities for offloading tempt us at every turn, as headlines warn of "digital dementia" and "cognitive surrender," it seems like a good time to take stock. Yes, cognitive offloading can save us time and effort. But what are its other consequences? My guest today is Dr. Sam Gilbert. Sam is a Professor of Cognitive Neuroscience at University College London. Sam and his colleagues have been trailblazers in the study of cognitive offloading—when we do it, why we do it, what it does for us and to us. Here, Sam and I talk about what cognitive offloading is, how deep it goes in our species' history, and how it pervades our everyday lives. We talk about the different forms that offloading takes. We discuss why some people offload more than others, and why we offload in certain situations. We walk through three bodies of research on the consequences of cognitive offloading—research on the so-called Google effect, on the photo-taking impairment effect, and on the impact of using GPS to navigate. Of course, we also address the elephant in the room: How should we think about the possible dangers—and benefits—of cognitive offloading in the new era of AI? Before we get to it, some news: We have re-launched the Many Minds newsletter, as a Substack! We'll be sharing each of our episodes there, as well as other morsels from time to time. We've been wanting to do this, in part, to give you a better way to engage with us—and with each other. Were there questions we should have asked? Are there connections you made that we didn't? Counterarguments we overlooked? Et cetera. All that stuff can now go in the comments for each episode. So, if you're a fan of the show, please do consider subscribing and following along with us there. Alright friends, on to my conversation with Dr. Sam Gilbert. Enjoy!

Coming of age in Ngogo
It's a familiar story in many ways. A child is born, and for years afterward is adored and indulged and anchored to home and family. But then the child grows up and starts crossing that long threshold into adulthood. The transition proves—to say the least—a bit turbulent. Now when I say this story is familiar, I don't just mean familiar to us as human beings. After all, a similar story has long played out among our closest cousins, the chimpanzees. My guest today is Dr. Rachna Reddy. Rachna co-directs the longstanding Ngogo Chimpanzee Project in Uganda and is an incoming Assistant Professor of Psychology at the University of California, Berkeley. For more than a decade now, she has been closely observing the chimpanzees at Ngogo—and especially the adolescents. Here Rachna and I talk about why adolescence—in all its intensity—is such a scientifically fascinating life-stage. We sketch the Ngogo research site, home to the largest group of chimpanzees ever studied. We unpack the different stages of chimpanzee life history. We zoom in on chimpanzee adolescence using a variety of different lenses—we talk about greetings, dominance hierarchies, grooming, social rejection, mentorship, deference, patrolling, female dispersal, and more. We discuss the so-called civil war that has taken root at Ngogo. And, finally, we talk about Rachna's in-progress novel (if that's the right word), which tells the story of one chimpanzee's coming of age in immersive detail. I think you'll enjoy this one folks. Chimpanzees offer us a kind of parallel universe, a funhouse mirror version of human life—one that is deeply relatable in some ways, and totally alien to us in others. And the parallels and non-parallels are arguably all the more striking in adolescence. But before we get to it, one humble ask: As the new season of Many Minds ramps up, this would be a great time to support the show. You could do this by rating us, writing a review on Apple Podcasts or a comment on Spotify, or by doing the old-fashioned thing of just recommending us to a friend or colleague. Your support is—as always—much appreciated. Alright friends, without further ado. Here's my conversation with Dr. Rachna Reddy. Enjoy! Notes 4:00 – Damien and several other chimpanzees discussed in this episode feature in the Netflix documentary series Chimp Empire. 8:00 – See here for a study by Dr. Reddy and a colleague on caregiving behavior in recently orphaned chimpanzee siblings. 13:00 – See here for a comprehensive recent article by Dr. Reddy and colleagues about puberty and adolescence in chimpanzees. 16:00 – The Ngogo fission—and subsequent "civil war"—is treated in detail in Chimp Empire and was the subject of a recent, widely discussed research paper (which includes Dr. Reddy as an author). 26:00 – "Tanner stages" are a widely used scale for measuring different phases of puberty in humans. 29:00 – For more discussion of life history stages and how these differ across species, see our earlier episodes here and here. For a recent report that Ngogo females experience menopause, see here. 36:00 – For some of Dr. Reddy's work on dominance hierarchies in adolescent male chimps, see here. 39:00 – For a detailed discussion of the chimpanze

The natural history of linguistic diversity
Thousands of languages are used around the world today, and this linguistic diversity is a precious part of our human heritage. But it's also more than that. Linguistic diversity provides clues—a vast crazy quilt of clues—about how language works, about how history has unfolded, about the dynamics of culture, and about the nature of the human mind. My guest today is Dr. Damián Blasi. Damián is an ICREA Research Professor based at the Center for Brain & Cognition at the Pompeu Fabra University in Barcelona. Over the last decade or so, Damián's emerged as one of the most innovative researchers in the study of language and linguistic diversity. He's been widely recognized for this work, and most recently was awarded the 2026 FABSS Early Career Impact Award from the Cognitive Science Society. In this conversation, Damián and talk about why scientists should care about linguistic diversity. We do a bit of linguistic diversity 101—how many languages there are, how we can enumerate them, how they vary from another. We discuss a recent paper in which Damian and his colleagues reconstructed the explosive rise and precipitous fall of human linguistic diversity over the last 12,000 years. We talk about the factors that drive language change. And we discuss how cognitive science relies too much on English and English speakers—and how this may be holding the field back. Along the way, Damián and I touch on the Tower of Babel, a golden age of linguistic diversity, the human bite configuration, scientific aesthetics, whether children shape language, polygenetic theories of language evolution, the pace of language change, schooling, linguistic inequality and behemoth languages, and why Damián thinks that possibility space of human language might be bigger and wilder than we currently imagine. This is a special episode of the Many Minds podcast. As I mentioned, Damián is this year's winner of an award from the Cognitive Science Society, in recognition of his outstanding early-year contributions to the field. He recently gave a keynote at the society's annual conference in Rio de Janeiro, and we've partnered with the Cognitive Science Society to feature this conversation about his work. I'll also mention that this wasn't my first time chatting with Damián—he's an alumnus of the Diverse Intelligences Summer Institute (DISI), the sponsor & incubator of this podcast. We met there a couple years ago, and so it was all the more fun to reconnect with him here. Alright friends, without further ado, on to my conversation with Dr. Damián Blasi. Enjoy! Notes 10:00 – The UNESCO page on multilingualism and linguistic diversity. 17:00 – The Ethnologue database. 20:00 – For examples of Dr. Blasi's work on "behemoth languages" and on how languages are not represented equally in terms of technological and development investment, see here and here. 26:00 - For the paper in which Dr. Blasi and colleagues introduced Grambank, see here.

From the archive: Electric ecology
Hi friends! We're still taking a bit of a summer pause. We'll be back at the end of August—in the meanwhile, enjoy this listener favorite from our archives! ----- [originally aired September 19, 2024] There's a bit of a buzz out there, right now, but maybe you haven't noticed. It's in the water, it's in the air. It's electricity—and it's all around us, all the time, including in some places you might not have expected to find it. We humans, after all, are not super tuned in to this layer of reality. But many other creatures are—and scientists are starting to take note. My guest today is Dr. Sam England. Sam is a sensory ecologist at the Natural History Museum in Berlin, and one of a handful of scientists uncovering some shocking things about the role of electricity in the natural world. Here, Sam and I have a wide-ranging conversation about electroreception—which is the perception of electrical stimuli—and electric ecology—which is the study of the ecological roles of electricity. We talk about how an interest in electroreception first got started, and why it's recently resurged. We discuss aquatic electroreception versus aerial electroreception, active electroreception versus passive electroreception. We talk about how electroreception is actually kind of easy to evolve. Along the way, we consider electrolocation and, its analog in sound, echolocation. We touch on dolphins, sharks, echidnas, ticks, caterpillars, bees, and spiders. We zoom in on electrostatic pollination, and what is inarguably the coolest sounding anatomical structure known to biology: the ampullae of Lorenzini. I think you'll enjoy this one, friends. As Sam describes here, electroreception is one of those "alien senses"—it really challenges the imagination. And electric ecology is one of those frontiers in our understanding of the natural world. So without further ado, here's my chat with Dr. Sam England. Enjoy! A transcript of this episode is available here. Notes and links 3:00 – For many of the topics discussed in this episode, see this comprehensive recent review of electroreception and electric ecology by Dr. England and a colleague. 7:30 – A paper reviewing the (contested) phenomenon of electromagnetic hypersensitivity in humans. 9:30 – An encyclopedia article on electroreception in monotremes. 13:00 – An early study of electrolocation in "weakly electric" fish. 17:00 – A popular article about the discovery of electroreception in sharks. 20:30 – A 2013 study showing that bumblebees detect the electric fields around flowers. 23:30 – A recent review of electroreception and its evolution in fish. 25:00 – A study demonstrating electroreception in the Guiana dolphin. 34:00 – A recent <a href= "https://www.cell.com/current-biology/fulltext/S0960-9822(23)00772-8?_hsmi=263616874&_hsenc=p2ANqtz--faOOOSB

From the archive: Varieties of childhood
Hi friends! We're taking a bit of a summer pause. We'll be back soon—in the meanwhile, enjoy this listener favorite from our archives! ----- [originally aired July 10, 2025] Childhood is a special time, a strange time. Children are adored and catered to—they're given their own menus and bedrooms. They're considered delicate and precious, and so we cushion them from every imaginable risk. Kids are encouraged to play, of course—but very often it's under the watchful eye of anxious adults. This, anyway, is how childhood looks in much of the United States today. But is this the way childhood looks everywhere? Is this the way human childhoods have always been? My guests today are Dr. Dorsa Amir and Dr. Sheina Lew-Levy. Dorsa is an Assistant Professor of Psychology & Neuroscience at Duke University, where she runs the Mind and Culture Lab. Sheina is an Associate Professor of Psychology at Durham University in the UK, where she co-directs the Forager Child Studies research group. Both Sheina and Dorsa have spent much of their careers thinking about how childhoods differ across cultures—and why. In this conversation, I talk with Dorsa and Sheina about their fieldwork with indigenous groups in Ecuador and the Congo, respectively. We discuss the different ways that childhood differs in these places—for instance, in terms of parents' attitudes toward risk, in terms of the social structures and activities in which kids are embedded, and in terms of the freedom that children are granted. We discuss developmental psychology's "WEIRD problem." We talk about the quasi-autonomous cultures that children create among themselves—sometimes called "peer cultures"—and discuss how these kid-driven cultures end up shaping and benefit the larger community. Along the way, we touch on adult supremacy, adverse childhood experiences, walking the forest and climbing papaya trees, parenting norms, ding dong ditch and "nananabooboo", the pioneering work of the folklorists Iona and Peter Opie, teaching, toys, and the enduring question of what childhood is for. Alright friends, lots to think about here. On to my conversation with Sheina Lew-Levy and Dorsa Amir. Enjoy! A transcript of this episode is available here.

From the archive: Philosophers on psychedelics
Hi friends! We're taking a bit of a summer pause. We will be back soon—in the meanwhile, enjoy this listener favorite from our archives! ----- [originally aired May 14, 2025] Some call it the "psychedelic renaissance." In the last decade or so, interest in psychedelic drugs has surged—and not just among Silicon Valley types and psychiatrists and neuroscientists. It's also surged among a stereotypically soberer crowd: academic philosophers. The reasons are clear. With their varied and sometimes transformative effects, psychedelics raise ethical questions, epistemological questions, metaphysical questions, questions about the nature of experience and the nature of the mind. My guest today is Dr. Chris Letheby. Chris is a philosopher of cognitive science at the University of Western Australia and the author of the 2021 book, Philosophy of Psychedelics. Here, Chris and I talk about the so-called classic psychedelics—LSD, psilocybin, ayahuasca, and others—and how interest in them has gone through three distinct waves. We discuss the effects that these substances seem to have, in particular their capacity to treat certain psychiatric conditions and their tendency to induce "mystical-like" experiences. We consider the idea that psychedelics might serve as agents of moral enhancement. And we dig into the psychological and neural mechanisms by which psychedelics seem to have their diverse—and often salutary—effects. Along the way, we talk about ontological shock, comforting delusions, brain plasticity, unselfing, microdosing, placebo effects and adverse effects, physicalism and idealism, the REBUS model, environmental virtues, plant consciousness, meditation, and much more. Maybe this is obvious but this episode is not just for the seasoned psychonauts out there. Whatever your personal experience with these substances, they offer a distinctive window into the mind—a new way of grappling with big questions. Perhaps this much is also obvious but we're not encouraging or endorsing the use of psychedelics here—just offering a little fuel for your intellectual fires! Alright friends, on to my conversation w/ Dr. Chris Letheby. Enjoy! A transcript of this episode is available here. Notes and links 4:00 – For a brief historical overview of research into psychedelics, see this paper. 8:30 – For work by an early trailblazer in the philosophy of psychedelics, see Thomas Metzinger's Being No One. 12:30 – For our earlier episode on the psychology and philosophy of visual illusions, see here. 18:00 – For a history of the concept of "set and setting," see here. 19:00 – A 2024 review of "adverse events" in classic psychedelics. 26:00 – A blog post on the history of the term "psychedelic." 27:00 – A recent review and meta-analysis of the use of psychedelic therapy for depressive symptoms. 31:00 – On mystical experience see Walter Stace's classic work, Mysticism and Philosophy. On the measurement of mystical-type experiences, see, e.g., Walter Pahnke's paper here. 36:00 – On the idea of "psychoplastogens," see <a href= "https://
