What can AI teach us about the mind?
Many Minds
Everyone is talking about AI these days. Often these conversations are about how AI might upend education, or work, or social life, or maybe civilization itself. But among cognitive scientists and psychologists the conversation inevitably drifts toward other questions. What does this latest generation of AI tell us about the human mind? Is it putting old ideas and theories to rest? Is it ushering in new ones? Will AI—in other words—also upend cognitive science? My guests today are and . Mike is a Professor of Psychology at Stanford University, where focuses on language learning and...

Mutualisms all the way down
Many Minds
No one is an island. We all depend on each other in critical, often tangled ways. And when I say "we" and "each other" I don't just mean humans. Yes, we humans rely on other humans. But we also rely on bees, yeasts, dogs, bacteria, and countless other creatures big and small. These interspecies dependencies—or mutualisms, as biologists call them—have deflected and inflected our history. And there's no doubt they will also inflect our future. My guest today is . Rob is Professor of Applied Ecology at North Carolina State University, where he studies the creatures and ecologies all...

Seven metaphors for AI
Many Minds
If you wanted a petri dish for understanding metaphors—how they emerge and evolve and jostle with each other—it would be hard to do better than the world of AI. We talk about AI systems variously as coaches or co-pilots, little genies or alien intelligences. Some researchers claim that AIs "grow," that they're entering their phase of "adolescence." Critics deride AI products as slop and dismiss LLMs as a kind of autocomplete on steroids. What's behind these different characterizations? Which ones are accurate and which are unfair? And are our metaphors mostly colorful rhetoric or do they...

Origins of the kiss
Many Minds
Humans do some pretty weird things. Some of us will sit in searingly hot rooms or jump into icy ponds. Others risk their lives trying to climb to new heights or dive to new depths. And every once in a while, two otherwise normal-seeming humans will lean in close to each other, open mouths, lock lips, and swap a hearty helping of microbes. You may even know people who've done this. But why? Are we the only animals who kiss? What could be the deeper origins of this truly bizarre behavior? My guest today is Dr. .

The aura of metaphor
Many Minds
Metaphors matter. They enliven our speech and our prose; they animate our arguments and stir our passions. Some metaphors power political movements; others propel scientific revolutions. These little figures of speech delight, provoke, captivate, shock, amuse, and galvanize us. In one way or another, metaphors just seem to help us make sense of a messy world. But how do they do all this? Whence their peculiar powers? What does it say about the human mind that we just can’t escape our metaphors—and frankly don’t want to? My guest today is . Steve is an Assistant Professor of...

From the archive: How should we think about IQ?
Many Minds
Hello friends, and happy new year! We're gearing up for a new run of episodes starting later in January. In the meanwhile, enjoy this pick from our archives. ------ [originally aired October 16, 2024] IQ is, to say the least, a fraught concept. Psychologists have studied IQ—or g for “general cognitive ability”—maybe more than any other psychological construct. And they’ve learned some interesting things about it. That it's remarkably stable over the lifespan. That it really is general: people who ace one test of intellectual ability tend to ace others. And that IQs have...

From 'On Humans': Can the brain understand itself?
Many Minds
Hello there, friends! We hope you're having a restful holiday, or a lively holiday, or whatever mix of those you prefer. As the year draws to a close, we at Many Minds are taking a much needed pause ourselves. But we wanted to share with you an episode from a podcast that we've been following for some time called . It's hosted by Ilari Mäkelä. It looks at humanity from all angles to understand where we come from and where we're going. The episode we're sharing features an interview with biologist and historian of science, Matthew Cobb; he's also the author of the book, . In...

In search of names
Many Minds
Alright, friends—we’ve come to the end of the 2025 run of Many Minds! Our final episode of the year is an audio essay by yours truly. This is a classic format for the show, one that we only do every so often. Today’s essay is about names. It’s about the question of whether animals have something like names for each other. And it’s also about a deeper question: What even is a name? How do humans use names? How does the historical and ethnographic record kind of complicate our everyday understanding of what names are. I had a lot of fun putting this together, and I do hope you...

The value of animal cultures
Many Minds
Not long ago culture was considered rare in nature, maybe even uniquely human. But that's changed. We now know that the tree of life is buzzing with culture—and not just on a few lonely branches. Creatures great and small learn songs, migration routes, and feeding techniques from each other. Many species build up reservoirs of knowledge over generations. This has profound implications, not just for our understanding of the natural world, but also for our efforts to protect it. My guest today is . Philippa is an Honorary Lecturer at the University of Exeter, with one foot in science and...

What is memory for?
Many Minds
Everyone loves a good evolutionary puzzle. Why do we have appendices? Why do we dream? Why do we blush? At first glance, memory would not seem to be in this category. It's clearly useful to remember stuff, after all—to know where to find food, to remember your mistakes so you don't repeat them, to recall who’s friendly and who’s fierce. In fact, though, certain aspects of memory—when you hold them up to the light—turn out to be quite puzzling indeed. My guests today are and .

[originally aired May 25, 2022]
When we think about ancient humans, we often imagine them doing certain kinds of things. Usually very serious things like hunting game and making tools, foraging for food and building fires, maybe performing the occasional intricate ritual. But there was definitely more to the deep past than all this adulting. There were children around, too—lots of them—no doubt running around and wreaking havoc, much as they do today. But what were the kids up to, exactly? What games were they playing? What toys did they have? What were their lives like?
My guest today is Dr. Michelle Langley, an archaeologist at Griffith University in Queensland, Australia. Michelle grapples with questions about children, play, and childhood in the deep past. In recent work, she draws on ethnographic reports to assemble a picture of what children have in common all across the globe. She then uses that understanding to cast new light on the archaeological record, to make fresh inferences about what kids must have been doing, making, and leaving behind.
In this conversation, Michelle and I talk about the kinds of basic activities that have long been a mainstay of childhood everywhere—activities like playing with dolls, keeping pets, collecting shells, and building forts. We discuss how archaeologists often assume that hard-to-interpret objects have ritual purpose, when, in fact, those objects could just as easily be toys. We talk about how children seek out and engineer “secret spaces”. We also touch on how a male-centric bias has distorted archaeological discussions; how the baby sling may have been the primordial container; and how otters stash their favorite tools in their armpits.
This is a super fun one, folks. But first a tiny bit of housekeeping: in case you missed the news, we have new newsletter. Seriously, who wouldn’t want a monthly dose of Many Minds right in their inbox? You can find a sign-up link in the show notes.
Alright friends, on to my conversation with Dr. Michelle Langley. Enjoy!
