Far more animals than previously thought likely have consciousness, top scientists say in a new declaration — including fish, lobsters and octopus.
Bees play by rolling wooden balls — apparently for fun. The cleaner wrasse fish appears to recognize its own visage in an underwater mirror. Octopuses seem to react to anesthetic drugs and will avoid settings where they likely experienced past pain.
All three of these discoveries came in the last five years — indications that the more scientists test animals, the more they find that many species may have inner lives and be sentient. A surprising range of creatures have shown evidence of conscious thought or experience, including insects, fish and some crustaceans.
That has prompted a group of top researchers on animal cognition to publish a new pronouncement that they hope will transform how scientists and society view — and care — for animals.
Nearly 40 researchers signed “The New York Declaration on Animal Consciousness,” which was first presented at a conference at New York University on Friday morning. It marks a pivotal moment, as a flood of research on animal cognition collides with debates over how various species ought to be treated.
What was obvious to most of us as kids (and what was attempted to be beaten out of us as kids) is now being accepted by scientists. Love it.
Right, I had no idea scientists were trying to say these animals weren’t sentient. Stupid scientists.
It’s not really that they all thought they didn’t, it’s that there was a lack of evidence to declare it to likely be true. Better testing methodology to exclude other possible explanations have contributed.
Ofc they are sentient.
I fail to understand why do we will push the ‘no expression of the face means no intelligence or emotions bcs most of us communicate that way’.
It always turns out that whatever brain mechanics we think of as our own we later & with minimal research find in other animals as well.
Evolutionary speaking too, same brain centres (with various density and relative size - of which we dont have all that dense brains & and most parts are underdeveloped), it’s absolutely unlikely we would have developed something new in a few millions of years (especially given smol & fragmented populations facing extinctions and smol gene pools - tho that could be interpreted the other way too). It’s just specialisation, some (advantageous) functions grew, other were optimised to the point of non-existence.
Then again, given how intolerant are we to our own species in terms of our emotional response to slight visual differences (I mean vcompletely evolutionary, uncanny valley thing, the next village of humanoids might have been competing for the same resources, which makes different culture/colours/face shapes = danger, etc), how we choose to ignore compassion (like ‘look at that idiot, ofc they have no feelings, not unlike me, the superior being’) … ofc we can’t immediately recognise and understand what and how animals are feeling. It takes a lot of time, effort, & empathy (mechanical empathy, like to fully underhand their environment from their pov, and emotional empathy, how they are processing that environment).
And the bigger the difference and habitats, the harder it is (like any sea animal really). Anything non-mammal seems alien to us, no matter the smarts (eg cuttlefish, that can clearly experience psychological trauma on individual and population/cultural level).
And then there are fungi. After that plants. And whatever we choose bacteria to be (like beings, or just a literal matter of environment we live within). Etc :).
Insects don’t really have brains. The complexity of their ganglia is not really comparable to what we consider a brain and seems rather unlikely that they have anything like our consciousness, just due to the difference in complexity. Does not mean we should treat them like shit, they are living creatures - but also not sure why we need to pretend they are something they are clearly not.
Jumping spiders show some level of consciousness. They’re intelligent predators that heavily use their sight to identify prey. They can recognise different prey types, learn their behaviours and adjust hunting strategies accordingly. A good example is how they are able to recognise when certain prey is acting odd, deduce it’s injured and drop their stealthy approach for a more direct one. They’re also capable of remembering their environment and using indirect and often complex paths to sneak up on prey.
Scientists have even observed them “dreaming”, which is likely when they do the information processing required for such comparatively complex behaviours https://www.nationalgeographic.com/animals/article/jumping-spiders-dream-rem-sleep-study-suggests
Bold claim to go from REM in sleep-like state to dreams and consciousness, and the original paper is not making that claim.

All of this seems rather possible even with basic learning mechanisms on molecular level. Not sure why you would claim that this need consciousness. But if you have a paper on this topic I would be more than interested to read them.
No papers that are actually concrete. Most of it is just speculation.
I’m not a scientist, and for me personally it’s enough to make me spend a bit longer thinking before immediately dismissing all insects as mindless automatons. Most probably are simple biological machines. Jumping spiders are however massive outliers in terms of insect intelligence, and a cursory Google search will provide a wealth of evidence for it.
I personally would also go as far as believing that they dream. I just don’t believe there’s a reasonable explanation for the REM like state other than some form of dreaming, even if rudimentary.
I’m not going to state that jumping spiders are fully conscious as 100% fact, there’s not enough proof for that. But they do have a proven ability to learn, and an ability to make somewhat complex plans. And all I’m trying to say is that we need more research before dismissing them so certainly.
I thought this should be obvious to anyone who’s interacted with an animal, ever. But sadly there are a great many people who don’t agree there is a ‘soul behind the tv screen’ as it were with animals more primitive than things like cats and dogs. It can be easy to use to justify human cruelty.
And it’s easy for you to say it’s obvious and you’ve thought that all along. You’re not the demographic they’re trying to inform.
I found that too many people who call themselves a dog person because they are terrible with animals. Dogs have been bred to put up with us. But give them a dog that’s either bred for a specific task, or one that is a bit feral and they’ll say the dog is difficult. It isn’t, the owner is just incompetent.
I’m no dog or cat person. It’s easier for me to name the animals I hate (damn mosquito’s). I get along with most animals, even instant-swatting cats labelled as difficult. Only because I respect their boundaries. And I’ve stuck my hand behind a fence to pet a pitbull more often than a sane person would consider healthy.
I think that pet breeding should be banned and only allowed by veterinairy instances, universities and animal shelters. Imagine if people couldn’t buy a pet on a whim? Imagine if they had to order in advance and get certified they know how to take care of one? We’d have less animal cruelty, and less strays.
Also, sheep are underrated pets. Holy damn they are social. They are basically a walking pillow and love scratches behind the horns. And wag their tail when happy. Same for rats. I say rats are more suitable as pets than dogs. Social, fun, trainable (be warned of the lazy males), don’t bite, love cuddles, and you don’t need to castrate them to “keep their fun behaviour.” You do have to remove the ovaria as it makes female rats prone to cancer otherwise.
I’m a dog person because between cats and dogs, I lack respect for cats. Yes they are cute and soft and sometimes cuddly. It’s not worth the ammonia smell everywhere and the scratching me when they come to me for pets, or the biting, clawing furniture, etc. Mostly the pee in the house.
I’ve done the things like changing the litter box and using new litter frequently. I’ve given them off limits spaces so they aren’t bothered. I’ve done the things and more. My daughter still has a cat downstairs. I’m not a jerk to the cat, but I just don’t like cats. I’ll pet, hold, play, etc. Cats are simply not a favorite for me.
Dogs… Ok the other hand… Obnoxious playful dopey friends that can learn cool things. Big cuddle bugs is what they are.
You share the same problem with the “too many people calling themselves dog people.” You state you lack respect to an animal, and then complain about said animal who is known to fight when threatened. That cat can tell you don’t like him, and so he doesn’t like you. Similar with horses. Just like many other animals, they sense your emotions. Except horses are very very good at it, and cats much less so.
Considering that as sentient beings ourselves, we don’t really even understand sentience, it’s kinda bold to assume we’ve got a monopoly on it.
Similarly I wonder how much of the observation is projection. We don’t know what the bee thinks it’s getting out of rolling the ball around, we don’t know that the fish was actually reacting to seeing itself. At some level we’re assuming that’s what’s going on because it makes sense to us.
Humans have a really, really hard time NOT assigning human attributes to every other living thing.
One thing that makes this hypothesis seem possible, is that some researchers are suggesting consciousness is external, and eternal. Meaning all living things are essentially antennae.
Source?
This is basic, but there are thousands of lectures, books, and papers on it, going back to the 80’s.

Or anything with Donald Hoffman, which there is a ton.
Basically, our brain just handles our cognitive needs, and filters consciousness, which is a fundamental property of the universe. Think what you will, but this is a pretty popular theory in the past decade or so. Among physicists and neurologists alike…
So, there’s a chance that there’s an afterlife, I mean if the brain isn’t the SOURCE of conciousness? But are you sure it’s popular? I heard neurologists were strictly “Brain is the source”
That really reeks of “scientists invent God.” And I question the actual motives of any researcher that would suggest such an idea.
Show me the data that suggest that. Describe a test that might prove it.
I think Penrose was talking about devising one. What do you think the motives would be?
It seems odd to me that this article is framing octopodes as a surprising inclusion. Aren’t they generally known to be some of the most intelligent animals of all?
Yes and no. It has long been known that they are surprisingly intelligent, but the structure of their nervous system is very strange and decentralized which makes it fairly surprising nonetheless.
I heard there’s a theory that they didn’t originate on earth
We have fossil evidence otherwise. Their greatest barrier to developing higher intelligence is that they die after reproduction, so they’ll never have pressures to develop more symbolic thought or pass on knowledge.
