Many Minds
A cluster of brain cells in a dish, pulsing with electrical activity. A bee buzzing its way through a garden in bloom. A newborn baby staring up into his mother's eyes. What all these entities have in common is that we don't quite know what it’s like to be them—or, really, whether it's like anything at all. We don't really know, in other words, whether they’re conscious. But maybe we could know—if only we developed the right test. My guest today is . Tim is Professor of Philosophy at Monash University in Melbourne, Australia. He’s a philosopher of mind and cognitive science,...

Welcome back friends! Today we've got a first for you: our very first audio essay by... not me. I would call it a guest essay, but it's by our longtime Assistant Producer, . If you're a regular listener of the show, you've been indirectly hearing her work across dozens and dozens of episodes, but this is the first time you will be actually hearing her voice. Urte is a philosopher. She works primarily in the philosophy of psychiatry, but also in the philosophy of mind, the philosophy of biology, the history of medicine, and neighboring fields. She's particularly interested in a colorful...

They tend to move under the cover of darkness. As night descends, they come for your gardens and compost piles, for your trash cans and attic spaces. They are raccoons, skunks, and coyotes. And if you live in urban North America, they are a growing presence. Whether you consider them menacing, cute, fascinating, or all of the above, you have to grant that they are quite a clever crew. After all, they've figured out how to adapt to human-dominated spaces. But how have they done this? What traits and talents have allowed them to evolve into this brave new niche? And are they still...

Hi friends, we're busy with some spring cleaning this week. We'll have a new episode for you in two weeks. In the meanwhile, enjoy this pick from our archives! _____ [originally aired Nov 30, 2022] 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've all seen those illusions. The dots seem to dance, when in fact they're completely still. The lines look like they bend, but in reality they're perfectly straight. Here's the thing: It doesn't matter that you know the ground truth of these illusions—the dancing and bending won't stop. And that we see the world one way, even though we know it's actually another way, is a fascinating quirk of our minds—and maybe a telling one. It suggests that there's a chasm between perceiving and thinking, that these may be two independent provinces of the mind. But, if so, we're faced with another...

If you want to have a rich social life, you're going to need to know who's who. You'll need to distinguish friend from foe, sister from stranger. And you're going to need to hold those distinctions in your head— for at least a little while. This is true not just for humans but—we have to assume—for other social species as well. But which species? And for how long can other creatures hold on to these kinds of social memories? My guests today are and . Laura is a biological anthropologist and postdoctoral scholar at UC Berkeley; Chris is a comparative psychologist and an Assistant...

Brains are not cheap. It takes a lot of calories to run a brain, and the bigger your brain, the more calories it takes. So how is it that, over the last couple million years, the human brain tripled in size. How could we possibly have afforded that? Where did the extra calories come from? There's no shortage of suggestions out there. Some say it was meat; others say it was tubers; many say it was by mastering fire and learning to cook. But now there's a newer proposal on the table and—spoiler—it's a bit funky. My guests today are , Postdoctoral Fellow at Aix-Marseille University, and ,...

Where do memories live in the brain? If you've ever taken a neuroscience class, you probably learned that they're stored in our synapses, in the connections between our neurons. The basic idea is that, whenever we have an experience, the neurons involved fire together in time, and the synaptic connections between them get stronger. In this way, our memories for those experiences become minutely etched into our brains. This is what might be called the synaptic view of memory—it's the story you'll find in textbooks, and it's often treated as settled fact. But some reject this account entirely....

Welcome back folks! The new season of Many Minds is quickly ramping up. On today’s episode we’re thrilled to be rejoined by . Michael is Associate Professor of Economic Psychology at the London School of Economics. He’s an unusually wide-ranging and rigorous thinker; though still early in his career, Michael has already made key contributions to our understanding of culture, intelligence, evolution, innovation, cooperation and corruption, cross-cultural variation, and a bunch of other areas as well. We wanted to have Michael back on—not just because he was an audience...

And we’re back! It’s been a while, friends. Hope you enjoyed your fall and your holidays. Thanks so much for re-joining us—we’re super excited to be kicking off a brand-new season of the Many Minds podcast. We thought we’d get things started this year with an audio essay, one partly inspired by some musings and mullings from my parental leave. Hope you enjoy it folks—and we’ll see you again in a couple weeks with our first interview of 2024. Now on to ‘Dawn of the smile.’ Enjoy! A text version of this episode is available .

My guest today is Dr. Sarah Benson-Amram. Sarah is Assistant Professor of Forest and Conservation Sciences and Zoology at the University of British Columbia; she also directs the Animal Behavior & Cognition Lab at UBC. Sarah's research group focuses on the behavioral and cognitive ecology of urban wildlife. They ask what urban wildlife can teach us about animal cognition more generally and try to understand ways to smooth human-wildlife interactions.
Here, Sarah and I talk about her work on that trio I mentioned before: raccoons, skunks, and coyotes. These three species are all members of the mammalian order of carnivora, a clade of animals that Sarah has focused on throughout her career and one that has been underrepresented in studies of animal cognition. We discuss the traits that have allowed these species—and certain members of these species—to thrive in dynamic, daunting urban spaces. We also talk about the big picture of the evolution of intelligence—and how urban adapter species might shed light on what is known as the cognitive buffer hypothesis. Along the way, we touch on: the neophilia of raccoons and the neophobia of coyotes, puzzle boxes, the Aesop's fable task, hyenas and elephants, brain size, individual differences, human-wildlife conflict, comparative gastronomy, and the cognitive arms race that might be unfolding in our cities.
If you have any feedback for us, we would love to hear from you. Guest suggestions? Topics or formats you'd like to see? Blistering critiques? Effusive compliments? We're open to all of it. You can email us at manymindspodcast at gmail dot com. That's manymindspodcast at gmail. Though, honestly, if it's really an effusive compliment, feel free to just post that publicly somewhere.
Alright friends, on to my conversation with Sarah Benson-Amram. Enjoy!
