Latest / Talking Science / Animal Intelligence – Minds Unlike Our Own
Transcript
- 0:00You know it happens to almost every single one
- 0:03of us at some point. Like you're just at the
- 0:05park or maybe sitting on your living room floor
- 0:07and you just happen to catch the eye of an animal.
- 0:10Oh yeah. Like your dog staring back at you. Exactly.
- 0:13Your dog or maybe a crow perched on a chain link
- 0:16fence or I mean even an ape if you're spending
- 0:18the day at the zoo. You lock eyes for a second
- 0:21and there is this quiet almost instinctual question
- 0:25that just pops into your head. Right. You're
- 0:27asking, how much is this creature actually like
- 0:29us? Yes. It's this profoundly human moment where
- 0:33we look across that species divide and we immediately
- 0:37wonder if they are running the same kind of internal
- 0:40software that we are. We really want to know
- 0:42if there is a recognizable mind looking back
- 0:44at us. Right. So we immediately start running
- 0:46them through this mental checklist. We ask ourselves,
- 0:49well, can it use a tool the way I do? Or, you
- 0:52know, can it figure out a puzzle? Could it learn
- 0:53a few words if I taught it? Exactly. And welcome
- 0:57to today's deep dive, where we are going to explore
- 1:00the mechanics behind that exact feeling. We have
- 1:04this really fascinating stack of source material
- 1:06today centered around an excerpted essay on animal
- 1:09minds. It's a great piece. It really is. And
- 1:12our mission for this deep dive is to unpack a
- 1:15massive, subtly misleading assumption that most
- 1:19of us make about intelligence without even realizing
- 1:21we're doing it. An assumption that honestly profoundly
- 1:24warps how we interact with the natural world
- 1:27around us. Yeah. And that assumption is that
- 1:29intelligence is essentially this single vertical
- 1:32ladder. Right. The ladder model. Right. So we
- 1:34tend to picture this tall ladder where you have,
- 1:37you know, the simple instinct driven creatures
- 1:39down at the very bottom. Then the slightly more
- 1:41clever mammals, a few rungs up. And then us.
- 1:44Yeah. Then us humans sitting very proudly right
- 1:46on the top rung, just looking down at the rest
- 1:48of creation. We treat nature like it's like a
- 1:51video game. game leaderboard. Well, that's a
- 1:53good way to put it. And humans always have to
- 1:55get the high score. Right. But the sources we
- 1:58are looking at today argue that grading animals
- 2:01based on whether they can do human things is,
- 2:04well, completely missing the point of what intelligence
- 2:07actually is. I mean, we do it because it's comfortable.
- 2:09We are using the only yardstick we intimately
- 2:12understand, which is our own human cognition.
- 2:14Right. But the fundamental argument of our source
- 2:17text is that nature was never arranged like a
- 2:19ladder at all. Intelligence is not this single
- 2:23linear progression toward human thought. So it's
- 2:26not a straight line upwards. Not at all. Instead,
- 2:29intelligence has evolved independently. many
- 2:32times over, along wildly different paths. And
- 2:35it did this to solve entirely different environmental
- 2:37problems. So basically, once you dismantle that
- 2:40imaginary ladder, the animal world completely
- 2:43transforms. It stops being the strict hierarchy
- 2:45of lesser and greater creatures. Yeah, it becomes
- 2:47something much more interesting. It becomes this
- 2:49vast branching gallery of minds. And I think
- 2:52the crucial takeaway here is that these minds
- 2:54aren't just, you know, cheaper, less impressive
- 2:56versions of human minds. Right, they're genuinely,
- 2:58fascinatingly other. Other. Exactly. So today
- 3:02we are going to walk through that gallery. And
- 3:05for anyone listening, we're taking our time with
- 3:07this. So you don't need a biology degree to follow
- 3:09along. Nope, not at all. And, you know, if we
- 3:11want to truly abandon our human centric bias,
- 3:14we have to start by looking at a form of intelligence
- 3:16that evolved in almost complete isolation from
- 3:19our own. Which brings us to the octopus. Yes.
- 3:22The perfect starting point. So for us vertebrates.
- 3:26And just to clarify, that means you, me, anyone
- 3:29listening who happens to have a bony spine. Right.
- 3:31Animals with a backbone. Right. So for us vertebrates,
- 3:34our intelligence is housed in this heavily armored
- 3:37centralized skull. We're warm blooded. We walk
- 3:40on land and our social structures are totally
- 3:43central to our survival. And the octopus is basically
- 3:46none of those things. Right. It is a completely
- 3:47soft bodied, solitary creature living entirely
- 3:50underwater. Biologically speaking, I read that
- 3:54it's actually much closer. to a garden snail
- 3:56than it is to a human being. It is. I mean, if
- 3:59you trace our evolutionary family trees backward,
- 4:02you had to go back roughly 600 million years
- 4:05to find the last common ancestor that humans
- 4:09and octopuses shared. Right. 600 million years.
- 4:12Yeah, it's a massive gap. Yeah. And that ancestor
- 4:14was likely this microscopic flattened worm just
- 4:18inching its way along the primordial seafloor.
- 4:21Wow. Yeah. So evolution took that simple organism
- 4:24and just split it down to entirely different
- 4:26developmental paths. So one path eventually leads
- 4:29to us, you know, inventing the wheel and recording
- 4:31deep dives. And the other path leads to this
- 4:33squishy eight -armed sea creature. Exactly. But
- 4:36the text highlights that despite being essentially
- 4:38a giant sea snail, the octopus is undeniably
- 4:42brilliant. I mean, the tricks they do are wild.
- 4:44They navigate intricate mazes. They figure out
- 4:47the mechanics of screw top jars just to get at
- 4:49the food inside. Which is impressive enough on
- 4:51its own. Totally. But the behavior that really
- 4:54stands out in the research is their tool use.
- 4:56Like some octopuses will carry heavy coconut
- 4:58shells across the ocean floor. Right, they just
- 5:00drag them along. Yeah, dragging them along just
- 5:03to have a mobile hiding spot to assemble later
- 5:04when they feel threatened. And that behavior
- 5:08right there is a massive cognitive leap. How
- 5:10so? Well... A soft bodied creature in a predator
- 5:13heavy ocean obviously needs armor. But carrying
- 5:17a coconut shell isn't just a neat physical trick.
- 5:20It actually demonstrates an ability to anticipate
- 5:23a future state. Oh, I see. Yeah, the octopus
- 5:26is not in danger right now, but it recognizes
- 5:28that it will be vulnerable later and it actively
- 5:30plans for that future need. OK, that is wild.
- 5:34But what makes the octopus truly alien, at least
- 5:37according to the text, isn't just what it thinks,
- 5:39but where that intelligence physically lives.
- 5:42Right. This is where it gets really strange.
- 5:44Because, OK. The fundamental building blocks
- 5:47of intelligence are neurons, right? The specialized
- 5:49cells that process information and make up a
- 5:51nervous system. Correct. And humans keep the
- 5:54vast majority of our neurons densely packed inside
- 5:56our heads. We are very centralized. But an octopus
- 5:59distributes its processing power. Like throughout
- 6:02its body. Yeah, exactly. Around two -thirds of
- 6:06an octopus's neurons are spread out along its
- 6:08eight arms. Two -thirds? Yep. And because of
- 6:11that unique biological distribution, Each individual
- 6:14arm can taste the water, feel its surroundings,
- 6:18and even initiate actions somewhat independently
- 6:21of the central brain. Okay, it reminds me of
- 6:23a corporate management structure. Oh, I like
- 6:25that. How do you mean? Well, human intelligence
- 6:28operates like a traditional company with a hyper
- 6:30-controlling CEO sitting in the corner office,
- 6:33the brain. Right, just micromanaging every single
- 6:36sensory input and physical output. Exactly. But
- 6:39the octopus's nervous system operates more like...
- 6:43like a coordinated committee of semi -independent
- 6:45branch offices. That's a really great analogy.
- 6:47So the central brain might set the overall goal
- 6:49like, hey, we need to hunt for crab today. But
- 6:52the branch offices, the arms, are out in the
- 6:54field making their own localized decisions. Yeah,
- 6:57they're deciding which rocks to reach under and
- 7:00how to coordinate the grass based on what they're
- 7:02tasting and feeling in that exact moment. It's
- 7:04so foreign. Like, how foreign is this way of
- 7:07thinking truly compared to our own experience?
- 7:10I mean, that distributed intelligence is profoundly
- 7:13foreign to us. We are so anchored to our singular
- 7:17centralized stream of consciousness. Trying to
- 7:20imagine a mind that exists simultaneously as
- 7:23a unified whole and as eight separate tasting
- 7:27thinking appendages, it really stretches the
- 7:31limits of our imagination. It really does. So
- 7:33if the octopus shows us that a centralized brain
- 7:36isn't the only way to process complex information,
- 7:39our next stop in the gallery shows us that you
- 7:41don't need a heavy mammalian brain to perform
- 7:43high -level computations. Yes. Let's look at
- 7:46the sky. Yeah, let's talk about corvids. And
- 7:48for those listening, corvids are the family of
- 7:50birds that includes crows, ravens, and magpies.
- 7:54And they are the absolute perfect counter -argument
- 7:56to the old ladder -style insult of being bird
- 7:59-brained. Right. I love that the text dismantles
- 8:02that. It's a completely outdated idea. Yeah.
- 8:04For a long time, early scientists assumed that
- 8:07because mammals have these large, heavy brains,
- 8:09physical size must equal processing power. So
- 8:12they thought a small bird brain simply couldn't
- 8:14hold complex cognitive software. Exactly. They
- 8:17assumed it was a hardware. limitation. But corvids
- 8:19routinely shatter that assumption. I mean, the
- 8:22essay notes they are among the greatest problem
- 8:24solvers in the animal kingdom. Oh, without a
- 8:26doubt. They don't just use found tools like the
- 8:29octopus, they actually manufacture them. Like,
- 8:32researchers have observed crows taking a straight
- 8:34piece of wire, evaluating it, and deliberately
- 8:38bending it into a hook so they can fish a piece
- 8:41of meat out of a plastic tube. Think about the
- 8:43cognitive load required for that task, though.
- 8:46It's a lot, right? It is. The bird has to recognize
- 8:50a problem, visualize a geometric solution that
- 8:53does not currently exist in its environment,
- 8:56understand the physical properties of the wire,
- 8:58and apply the necessary force to bend it. All
- 9:01while looking at a piece of meat it can't even
- 9:03reach yet. Right, and then use the tool to manipulate
- 9:06an object it cannot even directly see inside
- 9:08the tube. Many primate species, you know... our
- 9:12closest genetic relatives, really struggle with
- 9:14that level of abstract physics. Wait, really?
- 9:17A primate would struggle with that? Oh, yeah.
- 9:18A lot of them wouldn't figure out the wire bending
- 9:20part. That is amazing. And they also hold grudges.
- 9:23The text details how crows can recognize individual
- 9:27human faces and will hold a grudge against a
- 9:29specific researcher for years. Yes. The facial
- 9:33recognition is incredible. And they even teach
- 9:35their flock mates to scold that specific person
- 9:38on site. But this brings up a massive question
- 9:41for me about the biological hardware. Okay, what's
- 9:44that? Well, humans and mammals have these big
- 9:47brains to hold all our intelligence. How on earth
- 9:51does a crow fit all of this, the tool manufacturing,
- 9:54the facial recognition, the social teaching,
- 9:56onto a physical brain the size of a walnut? It's
- 10:00a great question. And it comes down to, well,
- 10:02abandoning the idea that all brains are built
- 10:04on the exact same architectural blueprint. Okay.
- 10:07The text explains that the avian brain is wired
- 10:09completely differently than a mammalian brain.
- 10:12Their neurons are packed incredibly densely,
- 10:14and the connective pathways between those neurons
- 10:17are heavily streamlined. So it's kind of similar
- 10:19to the evolution of human technology, then? Like
- 10:21computers. Yeah. We moved from these massive,
- 10:24room -sized computers that relied on bulky vacuum
- 10:27tubes down to tiny silicon microchips. It's not
- 10:31about the overall physical size of the machine.
- 10:34Right. It's about the efficiency. Exactly. It's
- 10:36about how densely you can pack the transistors
- 10:39and how efficiently they route the information.
- 10:42Precisely. That specific architecture allows
- 10:45for high -level cognitive function without all
- 10:47the weight, which is, you know. Rather important
- 10:50if you need to fly. Ha ha. Yeah. I guess a heavy
- 10:52brain would be a liability for a bird. Definitely.
- 10:55Yeah. And you see this dense processing power
- 10:57vividly in their ability to perform mental time
- 11:01travel. Mental time travel. Yeah. So a corvid.
- 11:04will hide, or cache, food in hundreds of different
- 11:08locations across its territory to survive the
- 11:11harsh winters. Right, like squirrels do. Yes,
- 11:13but they don't just remember the geographic coordinates
- 11:15of the food. They remember what specific type
- 11:17of food they hid in each location. Oh, wow. and
- 11:21critically they understand the rate of decay
- 11:23wait so if they bury a piece of meat in a pile
- 11:25of nuts they know exactly how many days they
- 11:27have to retrieve the meat before it spoils they
- 11:30intentionally eat the perishables first and leave
- 11:32the non -perishable seeds for later in the season
- 11:35That is just mind -blowing. That requires spatial
- 11:38mapping, a complex memory timeline, and a clear
- 11:41understanding of time and decay all running seamlessly
- 11:44on that walnut -sized microchip. It really is
- 11:47definitive proof that nature found more than
- 11:50one way to construct a brilliant brain. But,
- 11:53you know, intelligence isn't only about manipulating
- 11:56physical objects like wires and coconut shells.
- 11:59Right. Because for some species, the greatest
- 12:01cognitive demands come from navigating a complex
- 12:04social web. Exactly. Which brings us back to
- 12:07the ocean. Yes. Specifically to the cetaceans,
- 12:10the marine mammal group that includes dolphins
- 12:11and whales. Unlike the solitary octopus, cetacean
- 12:15intelligence is inextricably linked to their
- 12:17societies. They are deeply, deeply social creatures.
- 12:20Right. Their survival in the open ocean depends
- 12:22entirely on how they relate to, communicate with,
- 12:24and hunt alongside one another. They cooperate
- 12:27in these really clever, coordinated hunts. And
- 12:30because vision is limited in murky ocean water,
- 12:33and smell is largely useless underwater, cetaceans
- 12:37have develop incredibly sophisticated auditory
- 12:40processing. To maintain those social bonds over
- 12:42vast distances, right? Exactly. Sound is everything
- 12:45to them. And the real revelation for me in the
- 12:47source material was the concept of the signature
- 12:50whistle. Oh, it's fascinating. Yeah. So individual
- 12:53dolphins develop this unique, highly specific
- 12:56frequency and rhythm pattern. And what researchers
- 13:00have found is that other dolphins in the pod
- 13:02will mimic that specific sound to call out to
- 13:06that particular individual. They're basically
- 13:08assigning a vocal label to... a specific member
- 13:11of their community which is a name for all practical
- 13:14observable purposes yes they're using names they
- 13:17are calling each other by name that is so cool
- 13:19but it goes beyond just communication right because
- 13:21they are actively teaching each other too yes
- 13:23they are the text points out that different pods
- 13:25of the exact same species of dolphin will develop
- 13:28entirely different localized hunting techniques
- 13:31depending on their environment Right, like one
- 13:34group might learn to trap fish by swimming in
- 13:37tightening circles to create this sort of net
- 13:39of mud, while another group, miles away, figures
- 13:42out how to hydroplane onto a muddy beach to snatch
- 13:45fish. And they don't just do it. They teach these
- 13:48specific techniques to their calves. Yeah. It
- 13:51reminds me of a family passing down a generational
- 13:53recipe. Where it isn't instinct coded into their
- 13:56DNA, it's learned behavior that belongs to a
- 13:59specific community. So does this mean dolphins
- 14:02actually possess a simple form of culture? I
- 14:05mean, yes. That is the textbook scientific definition
- 14:08of culture. Culture is the non -genetic transmission
- 14:11of habits, information, and traditions. Wow.
- 14:14When a behavior is learned socially rather than
- 14:16inherited genetically, you are looking at a cultural
- 14:18species. Okay, so if an animal has a name and
- 14:21participates in a distinct culture, it implies
- 14:24they have a rich inner life and a clear sense
- 14:26of identity. But how do scientists actually test
- 14:29for self -awareness in animals? It's notoriously
- 14:31difficult. But that brings us to one of the most
- 14:33famous behavioral experiments mentioned in our
- 14:36sources, the mirror test. Right, the mirror test.
- 14:39It was designed as a gold standard to check for
- 14:41self -awareness. And the mechanics are really
- 14:44simple. A researcher secretly places a mark,
- 14:47usually a dot of odorless paint on an animal's
- 14:50body, in a place where the animal cannot normally
- 14:53see it. Like on its forehead. Exactly. Then the
- 14:56animal is presented with a mirror. And if the
- 14:58animal looks in the glass, notices the dot on
- 15:01the reflection, and immediately reaches up to
- 15:03investigate its own forehead, it implies a profound
- 15:06cognitive leap. Right, because it means the animal
- 15:09understands that the entity in the mirror is
- 15:11not a stranger. It's a reflection of its own
- 15:14physical self. Yes. And great apes, elephants,
- 15:17dolphins, and some corvids have all passed this
- 15:19test. But the author of our source essay points
- 15:22out a massive structural flaw in how we interpret
- 15:25this test. A huge flaw, yes. Because the mirror
- 15:28test is a fundamentally visual puzzle. It is
- 15:30entirely reliant on sight. And because it was
- 15:34designed by human beings, well... We are intensely
- 15:37visual primates. Right. We navigate our reality
- 15:40through sight. So when we want to test another
- 15:42creature's intelligence, we instinctively build
- 15:44a visual obstacle course. Exactly. But in doing
- 15:48so, we ignore the concept of the umwelt. The
- 15:51umwelt. What is that exactly? It's a German word
- 15:54used in biology that means the unique sensory
- 15:56world that a specific animal inhabits. Okay,
- 16:00and the essay uses the example of a dog to illustrate
- 16:03this perfectly. Anyone listening who has a dog
- 16:05knows that a dog's reality is constructed entirely
- 16:08out of scent. They read the world chemically.
- 16:10Right. So if a dog stands in front of a mirror,
- 16:13it sees a flat piece of glass that just smells
- 16:16like glass. It doesn't smell like a dog. So of
- 16:18course, the dog fails the visual mirror test
- 16:20completely. But has no reason to interact with
- 16:22it as a dog. Exactly. But if you threw a human
- 16:25being into a room and asked us to identify ourselves,
- 16:28purely based on the unique chemical signature
- 16:30of our own scent left on a fire hydrant. We would
- 16:34fail completely. We would look incredibly stupid
- 16:36to a dog. So aren't we basically judging a fish
- 16:39by its ability to climb a tree here? Couldn't
- 16:42a dog have a deeply rich sense of self built
- 16:44out of scent rather than sight? I agree completely.
- 16:47and the text agrees. The failure isn't in the
- 16:50animal's cognitive ability. The failure is in
- 16:53the design of the test. A dog absolutely might
- 16:56possess a highly complex sense of self, but it's
- 16:59a self constructed out of a continuous narrative
- 17:01of scent. Rather than a visual portrait. Yes.
- 17:05And this is the central, humbling difficulty
- 17:08of studying animal minds. When we measure another
- 17:11creature, we can only build tests out of the
- 17:13building blocks of our own sensory experience.
- 17:16So we risk marking an animal as stupid simply
- 17:19because it's clever in a way we just didn't think
- 17:21to check for. We punish them for not being human
- 17:23enough. Exactly. And this leads directly into
- 17:25what scientists call the two perennial traps
- 17:28of animal observation. Okay, what are the traps?
- 17:31Because if our tests are so biased by our own
- 17:34human bubbles, how do scientists actually study
- 17:36these animals without getting it totally wrong?
- 17:38Well, the first trap scientists have to avoid
- 17:40is over -reading, which is anthropomorphism.
- 17:43Right, projecting human thoughts onto animals.
- 17:45Yes. It's our natural human temptation to project
- 17:49complex human emotions and thought processes
- 17:52onto animal behavior that might actually be driven
- 17:55by far simpler mechanics. Like when a dog tilts
- 17:58its head at you, it is so tempting to assume
- 18:01it's deeply pondering the existential meaning
- 18:03of your words. When in reality, it's probably
- 18:05just adjusting its... ear canals to pinpoint
- 18:07the source of a sound. Right, exactly. So scientists
- 18:10have to guard against that trap by insisting
- 18:12on rigorous, repeatable experiments rather than
- 18:15relying on charming anecdotes. But the second
- 18:18trap is far more insidious, and it's called under
- 18:20-reading. Under -reading. Yes. This is the mechanistic
- 18:23assumption that animals are basically just simple
- 18:25machines running entirely on blind robotic instinct.
- 18:29So denying them any inner life or subjective
- 18:32experience at all, it's like treating them as
- 18:34biological windup toys. Or simple computer algorithms,
- 18:37where a specific input strictly equals a specific
- 18:39output. Just because it's convenient or because
- 18:42we can't easily see the evidence. But why did
- 18:45science lean so heavily into that trap? Well,
- 18:47historically, it was a reaction against the overly
- 18:50sentimental nature writing of the past. For a
- 18:52large part of the 20th century, the scientific
- 18:54community demanded rigid, objective behaviorism.
- 18:58Ah. I see. Attributing thoughts, intentions,
- 19:00or feelings to an animal was seen as deeply unscientific.
- 19:04It was just safer for a researcher's career to
- 19:06treat an animal like a complex thermostat. But
- 19:09the text argues that the entire modern era of
- 19:12animal cognition is essentially the story of
- 19:14that thermostat model just crumbling to pieces.
- 19:17Animal by animal, experiment by experiment, with
- 19:21every new cleverly designed study that actually
- 19:24counts for an animal's unique. Well, we keep
- 19:28revealing capacities that we flatly denied were
- 19:30possible just a few decades ago. Right. We find
- 19:33tool use in octopuses, time travel in crows,
- 19:35and cultural transmission in dolphins. So how
- 19:38does modern science balance between these two
- 19:40extremes now? The only intellectually honest
- 19:42position left for a modern scientist is one of
- 19:45genuine uncertainty and open curiosity. We have
- 19:48to take other minds seriously. We have to acknowledge
- 19:50their depth without pretending we can magically
- 19:52climb inside their heads and know exactly what
- 19:55it feels like to be them. Exactly. We have to
- 19:57observe them on their own terms, not ours. So
- 20:01what does this all mean for you listening to
- 20:03this right now? What is the main takeaway from
- 20:06all the research we've explored today? I'd say
- 20:08the deepest lesson here is that We have to retire
- 20:12that ladder of intelligence for good. We really
- 20:14do. We have to tear it down and throw it away.
- 20:16There is no single vertical scale of cognition
- 20:20with humanity standing triumphantly at the summit.
- 20:24None at all. Instead, we live in this magnificent
- 20:26branching bush of different minds. Each branch
- 20:30was shaped by millions of years of evolution
- 20:32to thrive in its own specific, unique environment.
- 20:35You have the distributed, localized, tasting
- 20:37intelligence of the octopus branch. You have
- 20:40the dense, tool -making, time -traveling foresight
- 20:42of the corvid branch. And you have the highly
- 20:44fluid, social, name -calling world of the dolphin
- 20:47branch. And look, the human branch is extraordinary
- 20:50in its own right, absolutely. But it is just
- 20:53one branch among many. It is not the universal
- 20:56yardstick by which all other life must be measured.
- 20:59So the next time you look at the animals we share
- 21:01this planet with, whether it's a bird working
- 21:03at your backyard feeder, or a dog sniffing a
- 21:06fire hydrant on the street, or a documentary
- 21:08about creatures in the deep ocean, remember this.
- 21:11You are surrounded by real astonishing intelligence.
- 21:16It isn't a lesser, flawed version of your mind.
- 21:18It is something completely, beautifully different.
- 21:20The hard part was never their cleverness. The
- 21:23hard part was our own inability to recognize
- 21:25minds that don't look and operate exactly like
- 21:28our own. Exactly. Which leaves me with a final,
- 21:31slightly mind -bending thought for you to mull
- 21:33over as we wrap up. Oh, let's hear it. If we
- 21:36struggle this deeply to recognize, measure, and
- 21:38understand the intelligence of creatures, that
- 21:40we actually share a planet with creatures we
- 21:42share an evolutionary history and an environment
- 21:45with, what does that mean for our search for
- 21:48life out in the stars? That is a chilling thought.
- 21:50Right. If we were to ever encounter a truly alien
- 21:53intelligence out in the universe, would we even
- 21:56possess the sensory tools to recognize it as
- 21:58a mind at all? Think about that the next time
- 22:01you lock eyes with an animal. Thanks for joining
- 22:04us on this deep dive.
