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.

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.

[–] [email protected] 26 points 7 months ago (7 children)

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.

[–] [email protected] 14 points 7 months ago

We are limited by our own understanding and imagination, but I don't know any other explanation for silly little nonproductive activities other than "play". Is it because it is play, or is it beyond our understanding? We can't communicate with them, but we can draw parallels between their behaviors and our own natural behaviors.

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.

I dunno about all that, but I used to have an African fish that would always get the zoomies when I'd come home from work. He'd spit water at me or gravel at the glass to get my attention, and loved playing hide and seek and always brushed up on my hands when I was working on his tank. He never reacted this way to visitors, just me.

[–] [email protected] 12 points 7 months ago* (last edited 7 months ago) (2 children)

Exactly this.

And to get to this you need experience, research, and knowledge.

And trying to explain this to humans in general would take several generations in best case scenario (much less actually doing/changing anything with that knowledge).

Usually anything attacking the doctrine of how extra super special & way more unique than other equally unique species are is meet with severe (auto-?)hostility.

Even without our status in question, just the "threat" of something being slightly less/differently inferior to us is immediately attacked by the vast majority.

And once we decide something is inferior to us it takes extra effort to change the popular belief (like racism between humans as well - just designate some human as non-human & they are considered about as much as billions of yeast bacteria as we are baking bread).

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?

[–] [email protected] 17 points 7 months ago (7 children)

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.

Wasn’t this already obvious?

[–] [email protected] 52 points 7 months ago (2 children)

We don’t even know what sentience/sapience/whatever is. We have some thoughts, people argue about the definitions, and stuff; but really… it all comes down to… “are they like us”… but we don’t even really know what that means.

So no. It’s not obvious. (Particularly because humans are surprisingly stupid.)

[–] [email protected] 8 points 7 months ago

To people who spend a lot of time around animals or even sea creatures, it may be obvious that they’re more like us than most would assume.

This is self evident to any animal lover

[–] jaemo 16 points 7 months ago

It's self evident to anyone not plagued by speciesism, regardless of their feelings about animals; I don't think we ought to allow that much latitude to opt-out of the obvious moral consequences of this truth.

This reads like "scientists find that women have emotions and feeling and can feel pain"

[–] [email protected] 27 points 7 months ago

So arrogant are we

[–] [email protected] 27 points 7 months ago (1 children)

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 :).

[–] [email protected] 21 points 7 months ago (14 children)

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.

[–] [email protected] 6 points 7 months ago (3 children)

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

I've always thought this, and thought it strange we assumed other creatures experienced lesser levels of sentience.

This raises some interesting questions. The premise of these scientists is that consciousness can be quantified empirically. Yet many of the tests described in this article can be passed by machines. Does that mean that the scientists who signed the declaration consider some smart devices to demonstrate consciousness? And what are the implications?

IS veganism the real solution here, or is the real solution the all-artificial, all-synthetic diet? Me personally, I'm going to down this jug of red 40, and then I think I'll get back to you

If it ever comes out that plants are sentient and feel pain my moral compass is going to have a bad day.

I'm not even a vegetarian ... but I have tried to eat less meat in recent years, in part because of the cruelty.

[–] [email protected] 15 points 7 months ago (7 children)

I'd say eating plants would still be the lesser of two evils in that case. Animals we kill for food also eat plants, so from a pure quantity of suffering, it's better to not have the middleman there.

We can always go the way of only eating fruits (and fruit-like growths), as they're specifically meant for being eaten.

Im pretty sure i have read articles about study finding that show certain trees can communicate distress via pheromones or something when under attack by insects that strip their leaves and some plants give off a very faint 'noise' when they are dehydrated or distressed.

[–] [email protected] 5 points 7 months ago

Me too. I still eat cheese but no more meats. Regardless of the sentient thing, it's good for you to not eat meat.

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'd be tempted to go and say "no shit," but even the most obvious things have to be proven or tested. How you define consciousness can also change a lot.

Sometimes I confuse Sentient and Sapient in sentences but they actually don't mean the same thing at all.

[–] [email protected] 10 points 7 months ago (1 children)

In my opinion the idea of animal conscious has been fairly well supported for decades at minimum. There was a certain anti-consciousness orthodoxy in the animal behavior field that held back understanding of this topic. But I mean simple observation of animal behavior and the similar nervous structures surely leave animal consciousness the most likely explanation, even if it’s difficult to definitively prove.

A more interesting question in my mind is whether plants are conscious. This is a question that we truly have no idea how to answer.

[–] [email protected] 7 points 7 months ago (2 children)

The idea that turned me into a vegetarian is the realization that my pets most definitely had personalities, and what is a person if not something with a personality?

I might not be able to have a complex discussion about shared interests with them, but there are plenty of humans you can say the same thing about, and I'm still not going to eat them, or be okay with them being tortured from birth to execution.

No fucking shit... anyone with half a brain and a minimum of empathy already knows that.

Yes, yes, the scientific method doesn't discriminate between what is and isn't obvious, but the headline is, as usual, aimed at people with the intellectual capabilities of a 4 year old.

[–] [email protected] 7 points 7 months ago

Anything being that has a sense of self and other has a level of conscious awareness.
