Many Minds

Consider the peacock. Its plumage is legendary—those shimmering, iridescent colors, and those eerie, enchanting eyespots. But what often goes less appreciated (at least by us humans) is that this chromatic extravaganza is also a sonic extravaganza. The peacock's display operates in infrasound, an acoustic dimension that we simply can't hear without assistance. Which raises a question: If we're obl...

When we talk about AI, we usually fixate on the future. What's coming next? Where is the technology going? How will artificial intelligences reshape our lives and worlds? But it's also worth looking to the past. When did the prospect of manufactured minds first enter the human imagination? When did we start building robots, and what did those early robots do? What are the deeper origins, in other...

We're taking care of some housekeeping this week, so we're sharing a favorite from our archives. Look out for a new episode at the end of the month! --- Preferences, decisions, goals . When you hear these words, you probably think of humans. Or, if not humans then maybe charismatic animals—you know, great apes, certain species of birds, maybe dogs. In any case, I bet you think of creatures that ar...

Some of us are a little shy; others are sociable. There are those that love to explore the new, and those happy to stick to the familiar. We're all a bit different, in other words—and when I say "we" I don't just mean humans. Over the last couple of decades there's been an explosion of research on personality differences in animals too—in birds, in dogs, in fish, all across the animal kingdom. Thi...

There's an old view of the mind that goes something like this: The world is flooding in, and we're sitting back, just trying to process it all. Our minds are basically passive and reactive, always a step behind. Contrast that view with a new one that's quickly gaining ground. According to this alternative, we don't just react to the world, we anticipate it. We're not leaning back but trying to sta...

From one perspective, rituals are pure silliness. They might involve us waving our hands in a certain way and saying these exact words, in this exact order; we might put on a funny costume, or eat specific foods, or even subject ourselves to considerable amounts of pain. And we don't just perform these rituals once either—we tend to do them over and over again, year after year. Seen in this way, r...

If your podcast listening habits are anything like mine, you might be out for a walk right now. Maybe you're wandering the neighborhood, just blocks from home, or maybe you're further afield. In either case, I'm guessing you're finding your way without too much trouble—you're letting some intuitive sense steer you, track how far you've gone, tell you where to go next. This inner navigator of yours...

And we're back. We're rested, we're rejuvenated, and we're ready for Season 4 of Many Minds ! We're also, frankly, a bit hot. As I am recording this there is a heat dome parked over California and there is sweat under my headphones. But, more to the point, we've got a great episode to kick the new season off. My guest today is Dr. Irene Pepperberg . For more than forty years now, Irene has been do...

Friends, here's another favorite episode from our archives while we're still on summer break. Enjoy! ---- It's an old question: How does experience shape our minds and brains? Some people play the piano; others drive taxis; others grow up trilingual. For years now, scientists have examined how these and other kinds of life experiences can lead to subtle differences in our concepts and cortexes. Bu...

We're on break this month, but are sharing some favorite episodes from our archives to tide you over. Enjoy, friends!   I'm betting you've heard about the next generation of artificial intelligence, the one that's just around the corner. It's going to be pervasive, all-competent, maybe super-intelligent. We'll rely on it to drive cars, write novels, diagnose diseases, and make scientific breakthro...

The world is bigger than you think. I don't mean geographically, though maybe that too. I mean in terms of its textures and sounds and smells; I mean in terms of its hues and vibrations. There are depths and layers to the world that we don't usually experience, that we might actually never be able to experience. Our senses just aren't wired to take it all in. We're simply not tuned to all the dime...

Welcome back, friends! Apologies for the brief delay in getting this episode out. We're now happily back on track and super stoked for what we have coming up—starting with today's episode. My guest is Dr. Michael Tomasello, a voraciously interdisciplinary thinker, an incredibly productive scientist, and a pioneer in the systematic comparison of chimpanzee and human capacities. Mike is a Distinguis...

Have you ever pondered the letter P, or maybe reflected on the letter R? As in, thought about their structures, their shapes, and how they came to be. I, to be honest, had not. I have never given these letters—or any other letters—much thought. But that's what we're up to today. In this episode, we're looking across the world's hundred plus scripts and asking some basic questions: How are they ali...

Right now, as I'm recording this, there's an astonishing spectacle unfolding in the forests of Tennessee. Every June , vast swarms of Photinus carolinus fireflies light up the night there. The members of this particular species don't just blink erratically and independently. They sync up; they flash in a dazzling unison, creating waves of light that seem to propagate through the forest. But how do...

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...

Welcome back friends! Today's episode is an audio essay. Those who've listened to the show for a while now know that this is a classic Many Minds genre. But we actually haven't done one in quite awhile. This one takes on a topic that is big, consequential, and above all quite fun: our species' long-running obsession with our own uniqueness. I won't say too much more—don't want to spoil anything—bu...

Your friend is in a bit of distress. They've just been dunked in a pool, and they can't pull themselves out. You're looking on as they're paddling furiously, trying to hold onto the pool's ledge. Fortunately, there's a way to save your friend, to give them an escape route. The thing is, there's also something else vying for your attention at the moment: a chunk of chocolate. So what do you do? Do...

Welcome back friends and happy spring! (Or fall, as the case may be.) Today's show takes on a disarmingly simple question: What is language for? As in, why do we say things to each other? What do words do for us? Why do our languages label some aspects of the world, but not others? My guest today is Dr. Nick Enfield. He's Professor of Linguistics at the University of Sydney. Nick has authored or e...

Friends—we're busy with some spring cleaning this week, but will be back in mid-April. In the meanwhile, here's a favorite audio essay from our archives. Enjoy! ______ Welcome back folks! Today is a return to one of our favorite formats: the audio essay. If you like your audio essays short, concise, and full of tidbits, then this one will not disappoint. We take a look at a 140-year-old idea but v...

It's an old question: How does experience shape our minds and brains? Some people play the piano; others drive taxis; others grow up trilingual. For years now, scientists have examined how these and other kinds of life experiences can lead to subtle differences in our concepts and cortexes. But to really push on the question, to really explore the limits of how experience can rewire us, some resea...

To be a good magician, you have to be a good psychologist. If you want to pull off a really good magic trick, you need to know your audience—what they are likely to attend to or gloss over, what shortcuts they take, what predictions they tend to make. Which all raises a question: Could you get to know a new audience, a very different audience, by seeing which tricks they fall for and which they do...

I have this theory about podcasts—it's almost certainly not original, and it's probably not right. But anyway, I have this theory that what makes for a great podcast episode is really just a few good moments. Sure, it's nice if the conversation has a satisfying arc and good energy; it's great if it's not too dense or repetitive—all that stuff matters. But I think what really makes an interview sti...

You have a big brain. I have a big brain. We, as a species, have pretty big brains. But this wasn't always the case. Way back when, our brains were much smaller; then they went through a bit of growth spurt, one that lasted for a couple million years. This steady ballooning of brain size is one of the key themes of the human story. But then there's a late-breaking twist in that story—a kind of une...

You've probably seen those lists of the so-called "wonders of the world." Many are works of architecture: the Great Wall, the pyramids, the colosseum, Taj Mahal. But these lists are, in a sense, always incomplete. Our world holds other architectural wonders, after all—albeit ones that are hidden from human eyes, made from different materials, and a bit scaled down. I'm talking, of course, about th...

We're on a brief winter break right now, but we'll be back later in January. To tide you over, here's one of our favorite episodes from 2021: a conversation with Dr. Luke Rendell about culture in whales and dolphins. Enjoy! -- Whales and dolphins are, without a doubt, some of the most charismatic, enigmatic creatures around. Part of what draws us to them is that­—different as our worlds are from t...
