Animal, heal thyself
Many Minds
What happens to animals when they get sick? If they’re pets or livestock, we probably call the vet. And the vet may give them drugs or perform a procedure. But what about wild animals? Do they just languish in misery? Well, not so much. It turns out that animals—from bees to butterflies, porcupines to primates—medicate themselves. They seek out bitter plants, they treat wounds, they amputate limbs, they eat clay—the list goes on. This all raises an obvious question: How do they know to do this? How do they know what they know about healing and medicine? It also invites a related...

The rise of machine culture
Many Minds
The machines are coming. Scratch that—they're already here: AIs that propose new combinations of ideas; chatbots that help us summarize texts or write code; algorithms that tell us who to friend or follow, what to watch or read. For a while the reach of intelligent machines may have seemed somewhat limited. But not anymore—or, at least, not for much longer. The presence of AI is growing, accelerating, and, for better or worse, human culture may never be the same. My guest today is . Iyad directs the at the Max Planck Institute for Human Development in Berlin. Iyad is a...

How should we think about IQ?
Many Minds
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 risen markedly over the last century. At the same time, IQ seems to be met with increasing squeamishness, if not outright disdain, in many circles. It's often seen as crude, misguided, reductive—maybe a whole lot...

Rethinking the "wood wide web"
Many Minds
Forests have always been magical places. But in the last couple decades, they seem to have gotten a little more magical. We've learned that trees are connected to each other through a vast underground network—an internet of roots and fungi often called the "wood wide web". We've learned that, through this network, trees share resources with each other. And we've learned that so-called mother trees look out for their own offspring, preferentially sharing resources with them. There's no question that this is all utterly fascinating. But what if it's also partly a fantasy? My guest today is ....

Electric ecology
Many Minds
There's a bit of a buzz out there, right now, but maybe you haven’t noticed. It's in the water, it's in the air. It's electricity—and it's all around us, all the time, including in some places you might not have expected to find it. We humans, after all, are not super tuned in to this layer of reality. But many other creatures are—and scientists are starting to take note. My guest today is . Sam is a sensory ecologist at the Natural History Museum in Berlin, and one of a handful of scientists uncovering some shocking things about the role of electricity in the natural world. Here, Sam...

The nature of nurture
Many Minds
The idea of a "maternal instinct"—the notion that mothers are wired for nurturing and care—is a familiar one in our culture. And it has a flipside, a corollary—what you might call “paternal aloofness.” It's the idea that men just aren't meant to care for babies, that we have more, you know, manly things to do. But when you actually look at the biology of caretaking, the truth is more complicated and much more interesting. My guest today is . She is Professor Emerita of Anthropology at the University of California, Davis and the author of the new book, . In it, she examines...

The space of (possibly) sentient beings
Many Minds
We may not know what it's like to be a bat, but we're pretty confident that it's like something—that bats (and other mammals) are sentient creatures. They feel pleasure and pain, cold and warmth, agitation and comfort. But when it comes to other creatures, the case is less clear. Is a crab sentient? What about a termite, or a tree? The honest answer is we just don't know—and yet, despite that uncertainty, practical questions arise. How should we treat these beings? What do we owe them? My guest today is . Jonathan is a Professor of Philosophy at the London School of Economics and the...

Hi friends, we're on a brief summer break at the moment. We'll have a new episode for you in August. In the meanwhile, enjoy this pick from our archives! ---- [originally aired January 25, 2023] By now you’ve probably heard about the new chatbot called . 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,...

Hi friends, we're on a brief summer break at the moment. We'll have a new episode for you in August. In the meanwhile, enjoy this pick from our archives! _____ [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...

[originally aired May 25, 2022]
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 toys did they have? What were their lives like?
My guest today is Dr. Michelle Langley, an archaeologist at Griffith University in Queensland, Australia. Michelle grapples with questions about children, play, and childhood in the deep past. In recent work, she draws on ethnographic reports to assemble a picture of what children have in common all across the globe. She then uses that understanding to cast new light on the archaeological record, to make fresh inferences about what kids must have been doing, making, and leaving behind.
In this conversation, Michelle and I talk about the kinds of basic activities that have long been a mainstay of childhood everywhere—activities like playing with dolls, keeping pets, collecting shells, and building forts. We discuss how archaeologists often assume that hard-to-interpret objects have ritual purpose, when, in fact, those objects could just as easily be toys. We talk about how children seek out and engineer “secret spaces”. We also touch on how a male-centric bias has distorted archaeological discussions; how the baby sling may have been the primordial container; and how otters stash their favorite tools in their armpits.
This is a super fun one, folks. But first a tiny bit of housekeeping: in case you missed the news, we have new newsletter. Seriously, who wouldn’t want a monthly dose of Many Minds right in their inbox? You can find a sign-up link in the show notes.
Alright friends, on to my conversation with Dr. Michelle Langley. Enjoy!
