Many Minds

We've got something special for you today folks: bats. That's right: bats.  Ever since Thomas Nagel wrote his famous essay on what it's like to be a bat, these flying, furry, nocturnal, shrieky mammals have taken up roost in our scientific imaginations. They've become a kind of poster child—or poster creature?—for the idea that our world is full of truly alien minds, inhabiting otherworldly lifewo...

Why do we make music? Why do we love music? Well, you say, because it's in our nature. Our brains were sculpted over the course of evolution to delight in sonic sequences, to remember melodies, to revel in rhythms. Perhaps. But, actually, not everyone thinks music is an adaptation. Not everything we do was directly shaped by natural selection. And even if music was an evolutionary adaptation, that...

Welcome back friends! Cue the kazoos and the champagne—after a short summer snooze, we're much revived and ready for a third season of Many Minds ! I could not be more thrilled about the guest we have to help kick things off: Dr. Alison Gopnik. Alison is a Professor of Psychology and Affiliate Professor of Philosophy at the University of California, Berkeley. She's the author of several books, inc...

We're on summer break this week. Back in a couple weeks with the kick-off of Season 3! In the meanwhile, here's a favorite episode from our archives: a conversation with Dr. Rebecca Wragg Sykes about her 2020 book, Kindred . Enjoy! --- You probably think you know the Neanderthals. We've all been hearing about them since we were kids, after all. They were all over the comics; they were in museum di...

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 an outmoded and over-narrow way of thinking. They prop...

Public opinion can sometimes shift dramatically over time. Beliefs that were widely held a few decades ago may now seem antiquated or even repugnant. But what's driving these shifts? Is it individual people changing their minds? Or is it just folks with old-fashioned worldviews dying out and being replaced? My guest on today's show is Dr. Stephen Vaisey . He's a Professor of Sociology and Politica...

You've no doubt heard that—as humans—our sense of smell is, well, kind of pathetic. The idea goes all the way back to Aristotle, that we have advanced senses—especially sight and hearing—and then lowly, underdeveloped ones—taste and smell. It's an idea that has been repeated and elaborated over and over, throughout Western intellectual history. Along with it comes a related notion: that smells are...

Let's say you're out on the open sea, having a leisurely sail, when you suddenly encounter not one but two sinking boats. One is a boat with two dogs in it; the other is a boat with a single human in it. You can only save one of the boats, so which one do you pick? The answer may seem obvious—you save the boat with the human, right? For many adults—even those who have a special love for animals—th...

Welcome back folks! We've got an audio essay for you this week. It touches on art, music, the skin, the spine, individual differences, vestigial responses, tiny muscles. There's even some Darwin thrown in there. It's a fun one. Hope you enjoy it! A text version of this essay is available on Medium.   Notes and links 1:30 – The novel that very recently gave me goosebumps. 2:00 – A brief discussion...

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 theirs, different as our bodies are—we sense a certain kinship. We know they've got big brains, much like we do. We know that some cetacean species live long lives, sing songs, and form close bonds. If you're like me, you may ha...

Have you ever seen what seemed to be a spirit? Or heard a voice from an unseen source? Or maybe just sensed a presence and found yourself with goosebumps all over? These kinds of experiences can be incredibly powerful— life-altering, in fact—but they don't happen often, and they don't happen to everyone. So what drives this individual variation? Why do some of us have these extraordinary experienc...

Greetings, all! It's been a minute, but we're back, we're refreshed, and we're buzzing with excitement about the next few months of Many Minds . This episode we're talking about one of humanity's most powerful cognitive tools: numerals. Numerals are those unassuming symbols we use whenever we read clocks, check calendars, dial phone numbers, or do arithmetic. My guest on today's show is Stephen Ch...

We're doing some spring cleaning this week, but please enjoy this pick from our archives. It's a conversation with Dr. Alex Taylor that aired originally in September 2020.  We've got a terrific spring lined up for the show. See you in two weeks! --- There's a  viral video clip  from 2014—maybe you've seen it. It features a subject in a pretty remarkable psychology experiment. He's put in room full...

Welcome back folks! Don't want to get ahead of ourselves, but rumor is that in certain parts of the Northern Hemisphere, the signs of spring are starting to emerge—little buds and shocks of color. We'll be monitoring the situation closely over the coming weeks. My guest today is Melanie Challenger. Melanie is a writer and researcher whose work explores the relationship between humans and the natur...

Do you remember the first time you made a good joke? Most likely not. Turns out the first forms of humor emerge super early in infancy, before the first birthday even. We're not talking about stand-up routines here. We're talking about a more basic but no less interesting behavior: teasing. In what's known as "playful teasing," one individual intentionally violates another's expectations for the s...

Guess what folks: we are celebrating a birthday this week. That's right, Many Mind s has reached the ripe age of one year old. Not sure how old that is in podcast years, exactly, but it's definitely a landmark that we're proud of. Please no gifts, but, as always, you're encouraged to share the show with a friend, write a review, or give us a shout out on social. To help mark this milestone we've g...

Greetings friends and happy February! Today's episode is a conversation with Dr. Michael Muthukrishna, an Associate Professor of Economic Psychology at the London School of Economics. Michael's research takes on a suite of topics that all start from a single big question: Why are we so different from other animals? Part of the answer has to do with our neural hardware. There's no question we've go...

Today we've got another "behind the paper" episode for you. In it, we're talking about some of the most alien-seeming yet charismatic creatures around. I chatted with Dr. Alex Schnell , a Comparative Psychologist and Research Fellow at Cambridge University. We discuss a paper she recently published with a few colleagues titled, ' How intelligent is a cephalopod ?' I've been charmed by cephalopods...

Welcome to our first episode of 2021! Super excited to get this year going—we've got, I promise, lots of great conversations in store for you. But this week, to kick things off, we have a brief audio essay. It's about tracks—that's right, footprints. This might seem at first glance like a narrow topic but, fear not, it contains multitudes. I started thinking about this theme a month or so ago afte...

When you think of domestication, I bet you think of farm animals—you know cows and pigs and alpacas—or maybe house pets. You might think of corn or wheat or rice. You probably don't think of us—humans, Homo sapiens . But, by the end of today's conversation, I'm guessing you will. For this episode I talked with Dr. Brian Hare of Duke University. He's a core member of the Center for Cognitive Neuros...

Welcome back folks! Today's episode is a conversation about the nature of knowledge. I talked with Dr. Briana Toole, an Assistant Professor of Philosophy at Claremont McKenna College. Briana specializes in epistemology—the branch of philosophy that grapples with all things knowledge-related. In her work she is helping develop a new framework called "standpoint epistemology." The basic idea is that...

Today we've got another installment in our "behind the paper" format. In case you missed the first iteration, these are 30-minute or so interviews that dig into recent notable papers. This episode takes on a timeless question: Do concepts differ from one language to the next, or are they basically the same? Maybe you think we already know the answer. You've probably heard of cases where one langua...

You probably think you know the Neanderthals. We've all been hearing about them since we were kids, after all. They were all over the comics; they were in museum dioramas and on cartoons. They were always cast as mammoth-eating, cave-dwelling dimwits—nasty brutes, in other words. You probably also learned that they died off because they couldn't keep pace with us, Homo sapiens , their svelter, sav...

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 mini will not disappoint. We take a look at a 140-year-old idea but very much a radical one—the root-brain hypothesis. It was proposed by Charles Darwin in a book published in the twilight of his career. The idea, in short, is that plan...

Imagine a friend's face. How much detail do you see? Do you see the color of their hair? What about the curve of their smile? For many people, this mental image will be relatively vivid. A somewhat watered down picture, sure, but still a picture—still something similar to what they would see if that friend were sitting across from them. For other folks, though, there's no image there at all. There...
