A Cephalopod Has Passed a Cognitive Test Designed for Human Children (sciencealert.com)

I agree with the main thesis of the article, stated in the first paragraph. That idea of ”how important it is for us humans to not underestimate animal intelligence”.

I think folks in modern times are less & less prone to thinking animals are ‘dumb’. But 1 or 2 generations ago this was not the case. I think humans for a long time have regarded animal intelligence in an inferior light.

Cephalopods have proven to to be incredibly intelligent, and emotional. I think you could easily argue many of them are smarter than human children, maybe even a lot of adults :)

I highly recommend an episode of ‘Nature’ I saw recently on PBS about octopi. It’s called “Octopus: Making Contact”. It’s the story of a professor who decided to install a tank and keep an octopus in his home, and the relationship he & his daughter developed with it. Absolutely stunning!

Great post. Respectfully, though, I disagree with the excerpt above.

I find that urbanization has led to a disconnect between people and animals. In times past, a person would have regular contact with a host of domesticated animals (cattle, horses, mules, donkeys, sheep, goat, chickens, pigs, etc.) as well as the wild animals that are a part of everyday life in rural settings (rodents, possums, armadillos, foxes, coyotes, snakes, deer, birds, etc.)

Without question, people in the past had a far greater appreciation of the ‘intelligence’ and behavior of animals than modern city-dwellers.

One need look no further than the numerous metaphors that have been passed down from these non-urban times: stubborn as a mule, wise as serpents, cunning like a fox, horse-sense, wise as an owl, etc...

In short, I’d suggest that the more modern (or, perhaps, urbanized is a better word) the LESS appreciation one finds for animal intelligence.


I have family who still live a pretty rural life, close to nature. They care very little about animals compared to my urban friends and family. They view animals as little more than "moving things" or simply food.


You may be mixing apples and oranges...

The degree of ‘compassion’ one has toward an animal is not directly correlated to one’s opinions as to its intelligence.

My uncle raised pigs. A frequent topic of conversation was how smart they are. Without question, they’re smarter than dogs. (I had a pet pig growing up.)

Yet, we ate then.

An even more brutal example: slavery. It was obvious and undeniable that human slaves were intelligent; yet, that didn’t mean that compassion towards them was common.


Fair point. Interesting that human beings can keep those separated.


> One need look no further than the numerous metaphors that have been passed down from these non-urban times: stubborn as a mule, wise as serpents, cunning like a fox, horse-sense, wise as an owl, etc...

Are you sure that comes from nature observation ?

Satire used to criticize the powerful of the world picturing them as animals. So these associations might not come from where you think they do. La Fontaine's fables are a good example of that. He was not the only one to do that.


I have firsthand knowledge of the sayings in regard to mules, horses, and foxes. They are very accurate.

Never thought snakes were that ‘wise’ though. Don’t know about owls.


> I think folks in modern times are less & less prone to thinking animals are ‘dumb’. But 1 or 2 generations ago this was not the case.

The naturalist Jean-Henri Fabre, in the 19th century, made an extensive study of solitary, spider-hunting wasps. Much of what he discovered, with regard to the surprising complexity of their hunting and nesting behavior, became well known in his day - he was one of the first writers I discovered when I started delving into the literature to feed my own burgeoning interest in the aculeates, and one of the reasons his work is so easy to come by is that it was popular, and thus well preserved.

It was very much new to me, though; to whatever extent it had entered common knowledge a century and a half ago, it has since exited again. If anything, I think that in recent generations we have become less likely to recognize complex behavior and intelligence in nonhuman animals, not more so; that may be changing, but if so, I think it must have begun quite recently.


I believe I underestimated animal intelligence, and as an extension of that, animal consciousness. I have no proof that animals are intelligent or sentient or whatever. I do however have no reason to assume otherwise. As a result I’ve stopped eating meat almost entirely, and I suspect I’ll eliminate it entirely eventually. I still eat fish and shellfish.

I struggle to understand how I disregarded animal minds for decades, but I suspect it can be reduced to arrogance, convenience, and gluttony. It has been a difficult revelation in some ways. Cooking meat has almost been a part of my way of life; it’s something I took pride in and always did to the best of my ability. Now I don’t really have much interest in food at all.


The realization that animals in factory farms have a capacity to suffer, and are undoubtedly subjected to this suffering for the majority of their lives, has made me cut my meat consumption from every meal to occasionally on the weekends. Would love to cut it out completely but have not mustered the willpower to do so.

I think personally owning a pet dog and realizing they aren't biological machines simply responding to stimuli has helped me with that realization.


What if the suffering could somehow be guaranteed not to occur? Since that seems to be your only (main?) reason to give up meat, would you go back to eating it if the suffering didn't happen?

I think the parent comment to yours is more about avoiding meat because of compassion to the intellect/consciousness. Rather than avoiding meat in order to eliminate any suffering that may occur during "production" of it.

I'm curious because I'm pretty good at convincing myself that the meat I buy comes from animals that haven't suffered. And if it can actually be guaranteed (moose killed by hunter) I'm all-in on meat. But if I somehow "woke up" and realized that I didn't want to eat other living things because of compassion (or whatever) to their minds? I'm not sure that I could go back from that.


I think I'm somehow in the same situation, trying to avoid industrial farming in benefit of local, small farming. I can know for sure (for some of them) that the animal was well treated from the beginning of its life to the very end.

I am asking myself if it is better for the animal to live a decent life even if it is to be killed and ate at the end or not to live at all.


My hang up is basically this:

If I want the animal to have a good life, why do I/should I get to (or even want to) decide when and why that life should end? It seems very contradictory to me and necessitates a need for the taking of the thing I’m apparently attaching value to.

Also I know I don’t physically kill these animals on a stop watch, but I vote for their death with my wallet. I don’t see a significant difference. Actually, I think it’s somewhat worse than it I carried it out myself. That’s why I generally try to only eat seafood that I selectively harvest while diving. I can guarantee the final moments were as brief as humanly possible and the rest of its life were as nature intended.

So, I really struggle with this one part where I decide the animal has worth and should therefor have a good existence. However, I’m also deciding it should only have that until I decide I want to deep fry its muscles or something. So it must be that I’m deciding to be a benevolent killer or something, which is certainly better than a ruthless one, but leaves me a uncomfortable nonetheless. I need to justify my own need or desire to continue killing, or at least profiting from the killing.

That’s the part I can’t do so far. Do I actually need to eat them? No, so far I really don’t. My health is still good after quite a while and the initial cravings have subsided. Do I want to eat them? No, not anymore, although I do miss it from a culinary perspective. Does that justify killing them? Well, would it justify killing someone’s dog if I thought dogs were delicious? Or any dog? No, never - the notion is absurd.

Well. I suppose some people eat dogs. This has a significant cultural element to it.

Nonetheless I really can’t bring myself to convince myself that I have any good reason to eat animals. Though admittedly I make an exception for fish and shellfish. I feel strange about that. I mean, when I get in the water those fish are arguably smarter than I am. One thing I justify the action by is that at least in the water they have a natural chance and environmental advantage. It isn’t a relationship of control and systematic murder from birth to death.

In time I suspect I’ll stop eating fish too. I don’t know.

The more I think about it the more it becomes an existential matter to be honest.


I don't see why your reasoning shouldn't also apply to fish and shellfish as it does to other animals?

> would it justify killing someone’s dog if I thought dogs were delicious?

That's a bit silly. Regardless of the ethics of eating meat, there are a whole bunch of other reasons why you wouldn't kill someone's pet. Just like you don't dive into people's fish tanks for your seafood :)


I don't think there's anything inherently wrong with killing animals for sustenance. Animals die and get eaten without needing any help form humans.

My main objection is to the manner of which animals have to be raised and harvested in the most efficient manner to satisfy the ever increasing demand for meat in the world while still being bottom of the barrel in price. Has there been any evidence this can be sustained without wholesale suffering?

If you can ensure all the meat you purchase comes from the opposite of such conditions then all the more power to you. The meat I do eat I also try to purchase from better farm conditions, but I don't think that's always possible.


Why care about the suffering, but not about the extinguishing of a life? If the moment to moment experience of a thing has value, but the thing's actual existence does not, why should (humane) murder not be legal? I do implore you to wake up -- you are deluding yourself for the sake of the pleasure.

Death is a form of suffering. Whether the creature you kill knows it lives only to die for you, whether it can see and understand some aspect of its cage or not, you took it before its time. It is all the same wrong in the end.

Now, eating an animal that died of natural or uncontrollable causes, or using for-real excess milk or eggs? Sure, fine. But those are not at all sustainable activities at a population level. We have to do things to animals that cause real harm to ever get enough of those products to sell them, even if we treat the animals way better overall. (And it's still better to push for better treatment than to do and feel nothing!)

My own mental backflip: I do still eat meat, because I'm a selfish and horrible person. I accept my complicity in the evil. But I also know my own choices will not meaningfully change demand patterns, so I allow myself the pleasure of the flavours I grew up eating, and try not to dwell on it too much. Even the Buddha was said to eat meat if it was what was served -- but of course, would request not to be served it!

Regardless, I know full veganism is the only actually ethically justifiable choice, and I believe and hope it will one day be the only realistic or acceptable choice for all of us. I will advocate for it (I hope) strongly whenever I can. No being deserves any part of what we do to them for food, and most people have pretty awful reasons to continue to eat meat; often literally at the level of, "animals can't suffer!", or, "humans are a higher being!", which is a mind-blowingly horrific thing to understand people will assert even after being given the evidence. I find the dismissive attitude appalling and try to get friends to at least see it in its real light.

Personally, once I catch wind that the tide toward veganism is beginning to turn, or that we somehow achieved affordable ethically lab-grown cheap muscle+fat tissue meats, I'll gladly turn that page. Or, once the horror again resurges strongly enough to overcome the value of shepherd's pie, thanksgiving ham, or a hamburger.

It's not much of an intellectual position, but it's all I've got. I ask that you at least be honest with yourself: the beings you eat have suffered for your pleasure.


> Death is a form of suffering.

I don't think this blanket statement is true. eg: people often live long past the point that they enjoy being alive.

> Now, eating an animal that died of natural or uncontrollable causes, or using for-real excess milk or eggs?

What's "natural" in your opinion? Do you mean old-age, disease, natural predators or something else? Humans are natural predators. Death from old age/disease is often caused by environmental factors or stress.

Calling any of this "evil" is an interesting choice. Maybe this is all just how the world works and we have yet to accept that as a species. I do think our role in the food chain needs to be sustainably defined and understood.


Thanks for taking the time. It's an interesting argument that many people live past the point that they enjoy life, but I doubt you are really suggesting we would be right to kill those people without their direct consent. Euthanasia, where it is at all accepted as moral, typically requires consent. If you think you can get the consent of an animal to kill it, well... let's cross that bridge when we come to it! Regardless, 'death' in this instance is still not necessarily a pleasure -- it may just be the option with the least suffering, and even if there are exceptions to death as a form of suffering, it doesn't seem far off base. As living beings, we value life.

Next, I agree that "natural" could mean a lot of things. In this case, understanding that we're discussing moral involvement, I'm speaking about whether or not you have moral involvement in causing the death.

Paying for a burger from McDonald's is indirectly asking for the death of the cow. They wouldn't kill it if no one bought burgers, but we all know that people do buy burgers, so the blame is diffuse. We all share. But you, in eating it, still profit by the being's death, and it was ultimately a deed done for your benefit when you chose to pay them. Of course it is more direct if you pay a butcher to slaughter a cow, and far more direct if you wield the knife. Hit a deer with your car by mistake? Maybe that's like manslaughter levels of culpability.

As a sidebar, is a cow killed by a wolf a natural death? It happens 'in nature', and the wolf couldn't live without killing other things, so it is natural for a wolf to kill a cow. But... is the death a natural death? I do not feel it is. I cannot blame the wolf (as it does not know better and does not possess other actual options, like we do), but I do not think the cow exists for the wolf. To paraphrase Kant I think, each being is an end unto itself. The cow's most natural death is one of old age, i.e. what we would legally call 'natural causes'. Suppose that health care could have extended its life, well sure, but there's a limit of practicality.

Last, it would be possible to justify literally any act from the position of "maybe this is just how the world works and we have to accept it" -- so, again, sure. But slavery was 'just how the world worked' for a long time, and I feel I am better off, and I can think of a hell of a lot of other humans who are better off, for us eventually having not just accepted it. There are similarities.

Veganism is really the only choice that's morally consistent, intellectually honest, and doesn't rely on special permission. It is ultimately not really arguable that it is a terrible thing for us to do to breed them, to keep them, to manipulate them, to harvest their products, and to kill them, especially in the ways we do. One must rely on ideas like 'might is right', 'we are inherently special for reasons that must be taken on faith', or 'nothing really matters anyway, everything is relative', which are exactly the arguments that have been used to justify all past atrocities of our doing.


> Thanks for taking the time.

likewise :)

In terms of practicality, a wolf needs to eat too. Without wolves (or predators) we find over-population which leads to food scarcity which leads to suffering (queue yoda reference.)

I think there is a big difference between slavery (a dark human endeavor) and the natural order of the world. Humans didn't invent predators. At best, we conquered them and at worst, we became them while growing to become the second most dominant (and largely unchecked) biomass on the planet.

Given that plants have been shown to have feelings, I'm not sure where our idea that eating plants is morally superior to eating animals comes from. Some plants poison animals in order to fertilize their soil. Some people poison plants in order to have a somewhat pleasant looking front-yard. Many plants have developed obvious defenses against being eaten, much like animals. By eating fruit that has dropped to the ground, you are denying the plant its intent to reproduce.

I think that most humans are more capable of empathizing with other animals than with plants and that's the root of the sense of morality here. The hard truth is that no living thing wants to be eaten to death but every living thing needs to eat. The circle of life is a real thing, the carbon cycle relies on plants recycling decayed organic matter including animals.


> realizing they aren't biological machines simply responding to stimuli

I know what you mean, but on some level you and I are also "biological machines simply responding to stimuli". The difference is more in the complexity of said stimuli and responses in time and space :)


> I struggle to understand how I disregarded animal minds for decades, but I suspect it can be reduced to arrogance, convenience, and gluttony.

I don't think that cephalopods are arrogant when they eat other creatures, although I suppose they may be gluttonous. Why hold yourself to a higher standard than you hold the animals you refrain from eating?


>Why hold yourself to a higher standard than you hold the animals you refrain from eating?

For some, morality isn't fungible or based on the morality or others (animal or human). If someone is a thief and willing to rob you, does that mean its okay for you to steal from them? It seems reasonable to me to hold a personal code of ethics and standards that isn't dependent (or at all related) to the ethics and standards of others (if any).


That's why I like eating tuna! They're out hunting and killing, and then have one very bad day. Live by the sword ...


I think what you're suggesting is footed on the appeal to nature fallacy. What happens in nature is natural and therefor good.

Also, I'm not sure a cephalopod has evolved the physical and mental capability to vary its diet on command such that it can choose if it will feed on other animals or not.

At some level humans and cephalopods are just animals, and equivalent in that regard, but I'm not sure I accept the equivalence far beyond that or especially when it comes to morality.


> Why hold yourself to a higher standard than you hold the animals"

This cannot be how you approach morality. Animals routinely do horrific things to each other. Would you ever ask someone that question outside of a conversation on whom we kill to eat?


With apologies to Sinclair: it is difficult to get a man to understand something, when his dinner plate depends on his not understanding it.

Cooking is a source of pleasure and society. My cultural Christian inheritance (and yours?) is quite committed to the separateness of people and animals. Many people deny even the wholeness of the human species. Where is the mystery in your beliefs? It is only an inheritance you now reject.

You can come back to meat later, or not, in your own time. Sort of like when you go far enough left, you get your guns back. There is nothing shameful in a cat.


It's a very hard realization to have. I applaud you. I was vegan for a couple years, until I devleped tooth problems for the first time in my life, which spooked me and I quit. Now I just try to moderate my meat intake, consume the less-in-demand parts like tongue (nobody raises a cow for its tongue), and buy from sources that impose less, albeit clearly still substantial, suffering.

But that said, there's so much great vegetarian food to be eaten!


That reminds me of something, which I suppose goes against what I've been commenting here. The rest of my family still eats meat and rather than throw out bones I will freeze them, let them accumulate, then make a broth and drink it. It seems immoral to waste the bones, sort of like how it seems more moral to only seek out that which might otherwise be wasted. It's a grey area for sure. In that regard though I suppose I do still eat animals? I certainly wouldn't make the broth if my family wasn't eating meat, though.

And you're right, most of the world has amazing vegetarian food. It's daunting to take on learning all of it. Indian and Thai foods especially have been incredibly appealing to me lately. So much flavour and nutrition is possible and these people seem to have figured it out a long time ago.


Most of it is learned behaviour. There is nothing natural about it for children, but conditioning and culture largely makes us who we are as humans.

So I don't see the need to look down on yourself for realizing something new. It wouldn't be new if it was totally familiar. However, the knowledge itself is thousands of years old, and also evolving.

I was talking to a kitchen hand in New Zealand in an area with Kea. He described the escalating battle to keep kea out the rubbish bins. It started with a rock on the lid which they solved fast, and then various other hinderances to keep them out.

The kea sit and watch and learn over s day or 3 and then they are back in, causing chaos.

The kitchen staff were trying to solve each puzzle with time pressure, a job to do and bad weather. The kea looked to find it funny whole the poor worker was frustrated.


Every time I read about octopi I'm stunned at their intelligence and ability to connect with humans.

If our civilization lasts long enough, someday we'll all be reviled for eating animals, especially octopi and pigs.


Taken further, you might argue that there might be condemnation eventually of the whole concept of pets and work animals too. I'm not sure I "condemn" these ideas, but I don't have a pet because I think animals should be wild. I make my own ethical comprimises, though, don't get me wrong.

Harry Harrison wrote a book I read many years ago called West of Eden, where the dinosaur extinction event didn't occur. An advanced species of lizard used modified lifeforms for their tech. I have it on my list to read again. It does make you think people might be more symbiotic towards the world rather than what we have now.


How come you include pigs but leave out cows?


The parent commenter has probably, like me, heard that pigs are remarkably intelligent. I haven't heard the same of cows.

That may very well be a skewed understanding, but it's likely why they choose that grouping.


Personally, I don’t see cows as very different from dogs.

They’re just as social and emotional as dogs are.

Intelligence wise, dogs are probably a bit smarter. But how much, I don’t know, they don’t seem that radically different.


I suspect you have more experience than I, and I know my imagining is poorly founded!

I think pigs have just received enough good PR recently that they come to mind as another particularly intelligent animal.


Maybe the size also helps? Closer to a dog or a cat, cows are not.


> I think humans for a long time have regarded animal intelligence in an inferior light.

Well, it is objectively inferior. That doesn't mean that it's not intelligence.


Haha, ok in general you’re right. Maybe a poor choice of words. But also, in general, I believe we have vastly underestimated the intelligence of most other animals. Even ones that are demonstrably not that smart.


As someone who trained my dog to sit and wait for me outside a shop while I got coffee, which was a similar delayed gratification and I didn't even use treats, I think science might be underestimating just how stupid human children are.


Perhaps. Small children are also exceptionally accident prone.

On the other hand, human children are incredibly curious and experiment with everything. It may not be stupidity that keeps them from following directions.


Indeed!

There is much to be learned by occasionally breaking the rules.


To properly test, you'd need to:

1. Draw a triangle on your forehead

2. Make a shitty clone of yourself with a circle drawn on the clone's forehead, who comes out of the shop immediately after you walk in

Then see if your dog decides to follow the shitty clone, or whether it waits a couple minutes for the regular version of you.

Edit: also, repeat with many more dogs, many more dog owners, and many more shitty clones.


This made me laugh as a potential Rick & Morty episode


I've never heard of Rick and Morty, but take my advice, don't try to shop your screenplay to VCs. They took a dim view of my "Adult Stewie" concept last year (think "Young Sheldon" backwards). Try Hollywood.

Anyway, I think a fun cartoon would be the Flintstones with ceph, for example their screen could be a smaller ceph whose chromataphores are pixels.

[edit]

Old drawing, back of a napkin (apologies to MIT AI Memo 554):

Was literally thinking the Rick & Morty tie-in would be that Morty gets a pet cuttlefish who not only speaks, but insists that even though he is stuck in this aquarium, he says it is preferable to the pathetic existential prison of their inferior human minds, and he uses his mesmerizing persuasive power to turn the rest of the house into a hippie comumune of drifters who do whatever he wants, and ultimately directs them to attack celebrities. The cuttlefish's name is Charlie.

Recurring villain, probably gets his own show.


The 'dog' is Jerry. We all know it.


From the article:

Some primates can delay gratification, along with dogs, albeit inconsistently. Corvids, too, have passed the marshmallow test.

Having had a couple of human children, I would definitely not claim that they are anything but extremely clever, but then so are many primates, dogs, and corvids.


Yes. Children are literally little humans. They have enormous brainpower, they just lack the experience they need to use it properly.


That and their brains are insanely malleable. As someone who contemplated learning Irish as an adult, I have to say that their brains can do things ours simply can't.

And I learned Hungarian (and Portuguese) as a kid.


Adults can actually learn language much more quickly then children in my opinion.

The only issue is that there’s a critical window in there that shapes your accent.


I mean, the dog gets nothing for sitting and waiting. He stopped getting treats once training was over. So is he smarter than the kid that wonders off or comes inside demanding cake and acting cute?


https://www.vox.com/2015/4/7/8360143/dogs-intelligence-scien...

On the whole, psychologist and dog researcher Stanley Coren estimates, the average dog's intelligence is roughly as sophisticated as a 2.5-year-old baby's.


I have a 2.5 year old.

A few weeks ago she (on her own) decided to dry her wet painting by taping it to the heat vent. We have never used tape in any way similar to that, and certainly have never used the heat vent to dry anything (it being a long-term safety hazard, and potentially bad for the ventilation system).

She routinely falls on her face because of getting herself into ridiculous precarious situations (in disturbingly similar ways).

The problem is intelligence just isn't 1D no matter how much we wish it was. Delayed gratification, problem solving and communication ability are not necessarily highly correlated enough for a single metric to make sense of the three.


> She routinely falls on her face because of getting herself into ridiculous precarious situations

The clumsiness might be a different thing. Changes in height, weight, strength and sight and probably a load of other things come into this. If you change something about an adult it takes them a while to adapt.

The example that comes to mind is a pregnant woman squeezing though some gap. To any observer the attempt was obviously not going to go smoothly.


As a human researcher, I don't think that's a fair comparison. A 2.5-year-old human can talk in simple sentences. The experiments in that article don't really measure intelligence. Babies are just much more curious.

I think dogs are still surprisingly smart.


By that argument no animal, dolphin, porpoise, dog, gorilla, elephant can be as intelligent as a 2.5 year old baby because none of them have evolved a tongue and vocal apparatus capable of making the correct sounds.


> because none of them have evolved a tongue and vocal apparatus capable of making the correct sounds.

And the neurological development to process and produce speech. I'm no cognitive scientist but I think verbal speech and reasoning is a huge amount of what we call "intelligence" in humans and goes beyond simple communication of immediate facts or commands. I suspect babies do have similar problem solving abilities compared to those animals, but I think it's disingenuous to throw out speech just because a dog hasn't evolved vocal chords. They're also missing the brain to use them, with whatever that means for reasoning.


>And the neurological development to process and produce speech.

I put gorilla in there specifically for this reason - https://en.wikipedia.org/wiki/Koko_(gorilla)

Gorillas can't produce speech but they can process language at about the level of a 2-3 year old human. Which is roughly the level of intelligence that dogs were being described as having in the article I linked earlier.

>I'm no cognitive scientist but I think verbal speech and reasoning is a huge amount of what we call "intelligence" in humans and goes beyond simple communication of immediate facts or commands.

well I'm no cognitive scientist and I think differently than you do!

>but I think it's disingenuous to throw out speech just because a dog hasn't evolved vocal chords.

and I think it's disingenuous for out cephalopod overlords to claim I lack the ability to reason about potential threats because I don't shoot ink out of my fingers when in danger.

I mean I don't actually know or care that dogs might be as smart as a three year old or that any of the other animals I named might be; I just accept the findings of experts in the manner as being more likely to be correct than what I might think is the case. Still I am supposing none of the named animals are as smart as I am so I am certainly not threatened by the concept.


I'm a cognitive scientist. Intelligence is such a badly defined concept, it's almost useless to reason about "intelligence".

In humans, intelligence is often defined as "what is measured by an IQ test", which obviously doesn't work for either babies or animals.

So while you can say "some dogs can learn to understand hundreds of words, just like most babies", you can not really say "being able to tell words/people/emotions apart means an organism is intelligent"


I know a dog that sings along when his humans sing. It's obviously not a human voice, but the little thing is trying his best and totally nails the pitch and rhythm.


Our dog will howl along with some of the emergency vehicle sirens. Remarkably similar to the particular siren that is sounding outside. (We live on a 4 lane parkway an easy walking distance from a major hospital, so we get different sirens from many different jurisdictions. She'll sing (edit: said sign before) along or in back-and-forth with about 1/3 of the distinct sirens.)


She also can sign? That's amazing!


The comment history of this username really checks out!

I take zero offense and thank you for the correction, but it's somewhat amusing to think that someone presumably has two accounts and switches between them to make comments when a post is inadequately proofed.


dogs sign walls and trees all the time


Dogs can also talk in simple (<4 word) sentences: https://yewtu.be/watch?v=AHiu-EDJUx0


That’s not delayed gratification, it’s just obeying orders. In the marshmallow test it’s crucial that the subject makes their choice freely.


> I think science might be underestimating just how stupid human children are.

Human children are stupid by design (well, evolution). Language, culture, and technology are overtaking genetics as the more effective information transfer mechanism. As we shed our instincts to make room for learning, human children will be born more and more stupid over time. It's a trade-off: At the same time, human adults will have greater capacity for smarts. It is the increasing stupidity at birth which enables us to learn so much into adulthood.

Animals without developed language haven't been able to afford this progress. They are smarter than human children from birth, but are unable to learn as much. So while your dog outperforms a human child at waiting outside the store, it will never have the capacity for art, mathematics, nor engineering, no matter how hard you train it. Humans on the other hand, can be trained quite a bit.



I think we’re all too ignorant about potentially including/integrating other animals into the society, Doctor Dolittle style. Wouldn’t it be just fantastic?


Obedience and intelligence are different things.


> That seems like cuttlefish can exert self control, all right, but what's not clear is why. In species such as parrots, primates, and corvids, delayed gratification has been linked to factors such as tool use (because it requires planning ahead), food caching (for obvious reasons) and social competence (because prosocial behaviour - such as making sure everyone has food - benefits social species). > > Cuttlefish, as far as we know, don't use tools or cache food, nor are they especially social ...

This feels like an evolutionary attribution error, if that's a thing. Self control is different from a thumb; there aren't necessarily any genes that code for it.

My first guess would be that, in order for a creature to be as smart as a cuttlefish, it needs to have a mental model of spacetime and of itself. Self-control is just one of the many results of such intelligence.


If anyone is interested in cephalopod intelligence I heartily recommend the book: "Other Minds: The Octopus and the Evolution of Intelligent Life" by Peter Godfrey-Smith.


One of the most interesting concepts in the book was "efference copies." The idea is that your mind needs to distinguish between stimulus that you caused by voluntary action (moving your arm) versus stimulus that the environment causes (your arm being moved by something else), so you send these "echos" of your voluntary actions back to your brain and this is possibly where your sense of self comes from.


That. And the idea that the cuttlefish are perhaps showing their internal state via their changing color patterns and not as a sinajng device. And of course their fairly short lives.

Yes, that is excellent as well. And quite moving.


I second this recommendation. I think someone in HN recommended this, very fascinating. My respect and interest for octopuses and surprisingly cuttlefish went way high up after reading this book. Kudos to whoever recommended it!

It feels like we are wasting our time looking for aliens searching for them in the skies (especially the unscientific work around oumuamua).

They are living right beside us in the form of cephalopods. We haven't deployed enough science on these amazing creatures yet (without of course distributing them like putting them in cages), probably because it's not a sexy field as compared to say astronomy or other cool things...


Thanks all, for these references! My wife is into cephalopod intelligence. I'll forward this to her and ask if she has any other recommendations.

I do know there are a couple of websites for cephalopod enthusiasts:

The article doesn't mention this but that test is not very well regarded currently. It's basically a test of food security and trust in adults rather than any particular behavioral benchmark.


I think it's even worse than that. I hate this test because both now and as a kid I'd take the single marshmallow and just be done. I don't want two, even if you hand them to me back-to-back... let alone 15 minutes later.

I don't care if its my favorite treat either. I believed quite strongly that a little vs a lot doesn't matter: the best parts are in the anticipation, the initial bite, and enjoying the lingering aftertaste. Having more more bites to eat is a gimmick with nothing but downsides (however now I get how things like addiction can drastically alter that equation so the "more" is practically everything).

So show me a version of this test that doesn't have the assumption "all kids are greedy for food and the most successful ones will optimize for that" at its core.


The cuttlefish test was very different though. Instead of more food, it's about better food.


There's more to the paper, though only six cuttlefish:

>The other part of the experiment was to test how good the six cuttlefish were at learning. They were shown two different visual cues, a grey square and a white one. When they approached one, the other would be removed from the tank; if they made the "correct" choice, they would be rewarded with a snack.

>Once they had learnt to associate a square with a reward, the researchers switched the cues, so that the other square now became the reward cue. Interestingly, the cuttlefish that learnt to adapt to this change the quickest were also the cuttlefish that were able to wait longer for the shrimp reward.

I agree but this new adapted test for cuttlefish is actually pretty smart. They actually zone in on delayed gratification.


I mean the signature characteristic of the most famous Cephalopod in fiction is that it waits dreaming in its house in R'lyeh. Evidently not coming out until the food on offer is better, either.


You sure? I seem to recall some kind of mass hysteria happening fairly recently, made it was the first signs of his coming


It is a test, and it is used on humans. It isn't a qualification for human-ness, any more than "breathing" is.

Theory of Mind is much more a test of human-ness - a stage person-ness really. And yes, quite a few animals qualify.


Says more about how hard it is to design tests, than it does about this particular test. Lots of reasons for delayed gratification. Not all of them mean "as smart as humans".


That's not the conclusion: no one is claiming "as smart as humans". Intelligence is multidimensional, and along some dimensions animals outperform us by a long shot.

Some birds remember thousands of locations of their stashed food. Some animals have a detailed internal map of many square miles of land on which they live. Pick just about anything a typical 3 year old can do, and we can find an animal to outperform them in that respect.

Glad to see someone else referenced this book. For anyone who wants to learn more about just how difficult it is to peer into the minds of other creatures, I highly recommend this book. Also, it's filled with delightful anecdotes of animal behavior that you would only experience if you spent hundreds of hours observing an individual.


Sure they were; that's what the title implies. Else, why the comparison?

And I'm curious if those studies of animal intelligence, actually tried a human. Could I remember thousands of place I put stuff? I think I do. I have a whole house full of stuff, and can find most of it quickly. I remember where I kept my socks in an apartment I lived in 30 years ago.

So yeah no, animals maybe aren't ahead of us in cognitive function.


Animals certianly aren't ahead of us in human cognitive function, but that feels like a loaded competition. Humans do have a hard time imagining intelligence as anything other than what we have.


Not me. I can easily imagine animals having better senses and better integration of those senses.

But I have to doubt, when somebody claims (as in the title above) that some animal is cognitively more advanced that a human child. That's linkbait and best, and plain wrong at bottom.


There are implications of certain recent discoveries. Not to be mysterious, I'm talking about Levin's lab.[1] All cells "think" using the same bio-molecular machinery as neurons. Neurons are just denser and faster.

-> Intelligence is ambient.

All cells think, and all collections of cells (from biofilms and stomatolites on up) think. In computer terms all cells use compatible protocols and processors and the living world is a kind of biological internet ("Wood-Wide Web").

-> All life shares one mind.

Whatever mind is, if you believe it "runs on" the physical substrate of cellular internet, then our minds are not separate from the minds of other living things. This would explain a lot.

When I bring this up people often object that this is anthropomorphism, but don't see it that way. Since all living tissue is intelligent, I see humans as the anthropomorphism of that ambient intelligence of the biosphere.

-> The biosphere is the result of "intelligent design": it's own.

From early on, the evolution of life would have become (more deeply) self-referential through mental feedback, meaning that the advent of intelligence itself becomes a factor in the further evolution of life. Things like the great switch-over from anaerobic to aerobic metabolism and the concomitant massive increase in atmospheric oxygen may well have been deliberate choice on the part of the global mind. In any event, the reductive mechanistic view of "dumb" life is faulty. Earth is Solaris.

Now this changes nothing about evolution. It's still a chemical tautology with no purpose, and adaptive pressure doesn't stop just because cells can think. ("Science does not remove the terror of the gods.") The Earth as a single being still has to navigate the "slings and arrows of outrageous fortune". Gaia is mortal. Part of the reason living systems seem so wildly inefficient (an illusion) is that they are so inconceivably resilient. (Efficiency vs. inefficiency is meaningless in evolution: there is no purpose so there can be no measurement of efficiency.)

Uh oh the humans are on to us


Let's just complain about how click-baity the title is. It works every time.


*a biased cognitive test


> "They break camouflage when they forage, so they are exposed to every predator in the ocean that wants to eat them. We speculate that delayed gratification may have evolved as a byproduct of this, so the cuttlefish can optimise foraging by waiting to choose better quality food."

It's a bit of natural selection. I don't know if cephalopods have a 'patience' gene. If yes, then --> natural selection. The ones who didn't have this gene got eaten many generations ago. The ones who do (and their genetically blessed offsprings), are alive to 'tell the tale'.

This is a bit biased if you ask me. They examined only the ones thay they found. The ones they found are the ones that are alive. The ones that are alive are the ones that are patient.

To disqualify my above 'theory' the scientists must capture eggs of 100 (?) eggs, raise them, treat them all the same, and then release them in a controlled 'wild' environment and see how fast they get eaten/how many survive for how long.

Then they compare results with their observations in the wild.

I am not a marine biologists, so I probably wasted 30secs of your life (apologies).
