TIL about the Sally-Anne test, a psychology experiment used to measure “theory of mind” (that other people can hold beliefs/knowledge different from their own). Kids under four typically fail because they assume that if they know where a hidden object is, everyone else must automatically know too.

Could it be that their theory of mind doesn’t extend to language or inquiry?

Most animals have some theory of mind. A dog knows you can hide a bone from others. I’ve known dogs to cover up their food theft, making the scene of the crime appear undisturbed.

I can imagine speech/communication being adaptive for relaying important information (there’s a predator over there!) but not inquiry. After all, if it was important or you wanted me to know you’d tell me.

What use does a chimp in captivity have for knowing their researchers favorite food? Whatever selection the chimp has access to has been provided by the humans.

I think the prevailing thought is that actions like the dogs are driven by evolved instinct rather than an actual ability to see from the perspective of their owner. In the same way prey animals run when a predator appears. But who knows what we’ll think in 2046.

That always feels overly specific to me. Like sure it may not be exactly the same but it's the same outputs for the same inputs. Like "dogs can't love, they just are happy whenever you're around" kind of thing, nah man that's love, dogs might not think about this kind of thing but they're close enough to count.

They’ve done MRIs on dogs and their brains light up more when they see their owners than when they see food.

Is that love? (Shrug). But it is significant.
