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 .

Of breeds and brains
Many Minds
It's hard to say exactly when, but some tens of thousands of years ago, our best friends were born. I'm referring, of course, to dogs. This didn't happen overnight—it was a long process. And it not only changed how those canids behaved and what they looked like, it also changed their brains. As wolves gave way to proto-dogs, and proto-dogs gave way to dingoes and dalmatians and Dobermanns and all the rest, their brains have continued to change. What can we learn from this singular saga? What does it tell us about dogs, about domestication, and about brains? My guest today is . Erin is...

[originally aired May 17, 2023]
You know the feeling. You're trying to read or write or think through a project, maybe even just respond to an email, when your attention starts to drift. You may not even notice it until you've already picked up your phone or jumped tabs, until your mind has already wandered way off-piste. This problem of distraction has become a bit of a modern-day obsession. We now fret about how to stay focused, how to avoid time-sucks, how to use our attention wisely. But it turns out this fixation of ours—contemporary as it may seem—is really not so new.
My guest today is Dr. Jamie Kreiner, Professor of History at the University of Georgia. Jamie is the author of a new book titled The Wandering Mind: What Medieval Monks Tell us about Distraction. In the book, Jamie shows that Christian monks in late antiquity and the early middle ages were—like us—a bit obsessed with attention. And their understanding of attention fit within a broad and often remarkably detailed understanding of the mind.
In this conversation, Jamie and I talk about why monks in this era cared so much about distraction. We discuss how they understood the relationship between mind and body; how they conceptualized memory, meditation, and mind-wandering. We discuss some of the mnemonic techniques they used, some of the graphical and textual devices that helped keep them focused, and some of the metaphors and visualization techniques they innovated. Along the way we also touch on fasting, sleep, demons and angels, the problem of discernment, the state of pure prayer, the Six Wings mnemonic device, metacognitive maneuvering, and much more.
I’ll just say I really enjoyed The Wandering Mind. As Jamie and I chat about here, the book illuminates an earlier understanding of human psychology that feels deeply familiar in some ways, and delightfully strange in others. I think you definitely get a sense of that in this conversation.
Alright friends, on to my chat with Dr. Jamie Kreiner. Enjoy!
