When you think of the dinosaurs, you probably think of supersized lizards. At least I do. They were gargantuan, certainly, and maybe quite agile, but also a bit dim-witted. Maybe not markedly dim-witted, but definitely not the brightest. When dinosaurs terrify us it’s because of their giant jaws and their sheer size, not because they were especially clever or crafty. (Except for those velociraptors in Jurassic park, of course—they were terrifyingly wily.) But, in any case, who really knows? It’s...

Once upon a time there was a king and a bishop... No, I'm not actually going to tell you a story right now. I just wanted you to notice something: As I started into that, your mind likely shifted into a different mode. You might have started mentally salivating as you anticipated a coming morsel of fiction. That’s because stories are special; they work a kind of magic on us. Humans everywhere—in every known society, starting from a very young age—seem to hunger for narratives. But why? What make...

Not sure about you, but it seems like I spend most of my time in the future. We're told to live in the present, of course—and I try. But at any opportunity my mind just races ahead, like an eager puppy. I'm planning my next meal, dwelling on that looming deadline, imagining the possibilities that lie ahead. In one sense, all this time spent puttering around tomorrow-land is kind of regrettable. But in another sense it's really quite extraordinary. When we think ahead, when we cast our thoughts i...

By now you’ve probably heard about the new chatbot called ChatGPT . There’s no question it’s something of a marvel. It distills complex information into clear prose; it offers instructions and suggestions; it reasons its way through problems. With the right prompting, it can even mimic famous writers. And it does all this with an air of cool competence, of intelligence. But, if you're like me, you’ve probably also been wondering: What’s really going on here? What are ChatGPT—and other large lang...

Welcome back, friends—and a very happy new year! For our first episode of 2023 we're going big. We're examining the minds of some of the most massive, majestic megafauna around. My guest today is Dr. Joshua Plotnik . Josh is an Assistant Professor in the Department of Psychology at Hunter College, and the director of the Comparative Cognition for Conservation Lab . His work focuses on elephants—Asian elephants in particular. Josh studies how these creatures perceive and think, how they solve pro...

We're off this week but are excited to share a thought-provoking conversation from our archives, about the long-standing puzzle of why we (and other creatures) dream. Happy holidays from the Many Minds team! --- You may not remember much about it, but chances are last night you went on a journey. As you slept, your brain concocted a story—maybe a sprawl of interconnected stories. It took you to some unreal places, gave you superpowers, unearthed old acquaintances, and twisted your perceptions. M...

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 oblivious to the full vibrancy of the peacock's display, what other sounds might we be missing out on? ...

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 words, not only of artificial intelligences themselves, but of our ideas about those intelligences? ...

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 are more or less cognitively sophisticated. I know I do. But, according to some researchers, this is a...

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. This research is addressing questions like: What are the ways that individuals of the same species diff...

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 stay a step ahead—our minds are fundamentally active and predictive. And our predictions aren't just id...

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, rituals are frivolous, expendable, and mind-numbingly repetitive. And yet they’re also central . Ritu...

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 is doing all in the background, as your mind wanders elsewhere, and magically it gets it all right....

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 doing groundbreaking research on parrots, with a focus on how they think and communicate. She is best ...

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. But to really push on the question, to really explore the limits of how experience can rewire us, some...

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 breakthroughs. It will do all these things better, faster, more safely than we bumbling humans ever could. The ...

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 dimensions of reality’s rich splendor. But there is a way we can appreciate these hidden dimensions: wit...

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 alike? How do they differ? And why do they have the shapes that they do? My guests are Dr. Yoolim Kim a...

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 they do it? How do these tiny creatures pull off such a brilliant display? My guest today is Dr. Or...

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 t...

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—but, like a lot of our essays, this one’s a mix of history of ideas and contemporary science, leavened...

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 you first nab the chocolate and then free your friend? Turns out that most rats in this position—tha...

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 edited more than a dozen books on different aspects of human language and communication—books on word...

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.

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 don't? Could we use magic as a scientific tool, in other words, as a window into minds that may be qui...

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 stick out for us—and stick with us—are these little time slices. Charged little moments that burn a lit...

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 unexpected epilogue. You see, after our brains grew, they shrank. But when this shrinkage happened and—...

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 the wonders of the underworld. I’m talking about ant nests. My guest today is Dr. Walter Tschinkel. Wa...
