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.
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?
These arguments never make much sense because there’s no broadly accepted philosophical consensus on what sentience is.
I agree with this. I’ve read the statement that the scientists wrote and I honestly could not figure out what they are trying to say. I just don’t see how any of the tests they reference would challenge the idea that we don’t know how to define or test consciousness.
Sentience is not necessarily the same thing but its in a similar place. It may be possible to test depending on the definition.
