Many Minds

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 . Rachna co-directs the longstanding in Uganda and is an incoming Assistant Professor of Psychology at the University of...

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 . Damián is an based at the 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...

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...

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...

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,...

The origins of Darwin's ideas show art The origins of Darwin's ideas

Many Minds

No discipline, no sphere of intellectual life, has been untouched by the work of Charles Darwin. He died in 1882 but his ideas are very much alive; they're now central to how we understand the natural world, the human mind, non-human minds, plants, biogeography, morality and emotion, culture, language, and more. But where did his ideas come from? How did they grow out of his travels, his social circle, his hobbies, his particular cast of mind?  My guest today is . Janet is Professor Emerita at Harvard University in the department of the History of Science. She is perhaps best known for...

Many Minds

It’s tempting to see bioluminescence as an oddity, one of those rare eccentricities of life on earth. And, on land, maybe that’s true. But our planet is mostly water, and out in the open ocean bioluminescence is utterly commonplace. Creatures of all shapes and sorts sparkle and glow, glitter and pulse. But what are these displays for? Why did they evolve? How did light become the currency of the deep?   My guest today is . Sönke is a Distinguished Professor of Biology at Duke University, where he and his research group study the visual ecology of the ocean. He’s the author of...

Is Man the Hunter just a myth? show art Is Man the Hunter just a myth?

Many Minds

There's a story about of our past that you know well. It goes like this: At some point earlier in human evolution, we started to hunt. Men in particular—perhaps channeling some deep-seated aggressive impulses—began to seek out big game. This new food source, this bonanza of calories, was what allowed our brains to expand. It changed our bodies and our societies and sent our species off on a whole new track. In short, Man the Hunter made us human. This story—told in different versions, with different points of emphasis—has circulated for decades. It's been debunked and revived, rejected...

Babies, dogs, and the riddles of word learning show art Babies, dogs, and the riddles of word learning

Many Minds

It's kind of astonishing, really, that kids ever learn words. Each one poses a little riddle. Does this sound string refer to a person? A category of things? Or maybe some other feature of the blooming, buzzing world? And yet word learning happens. In fact, we now know it begins earlier in infancy than we realized. And we now know, further, that dogs (or at least some dogs) understand words as well. So how does this happen? What do babies and dogs really know about words? And how might we go about figuring this all out? My guests today are and Dr. Claudia Fugazza. Elika is an Associate...

The inner life of the hand show art The inner life of the hand

Many Minds

Newton saw in the human hand proof of the divine; Darwin saw a key to our species' success. Many others, too, have described the hand in hyperbolic terms, as a paragon of design, a cornerstone of human uniqueness, an engine of our achievements. But what makes the human hand so powerful? Is it the proportions of the fingers? Is it the opposability of the thumb? Or, could it be none of this? Could it be that the real power of our hands lies—not in the physical design—but elsewhere, out of sight?  My guest today is . Matt is Professor of Cognitive Neuroscience at Birkbeck, University of...

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 I 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. We discuss a recent paper in which Damián 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 the 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-career 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!
