I might be dumber than the AI because I don't know the answer. Bob looks around? I mean the toy is not there when he comes back. Where else can he check?
The idea is if someone said "under the desk" they might not understand that people have different subsets of information, i.e. Bob wasn't there when Alice hid the toy, so he doesn't know it's not in the box where he left it until he checks himself.
Or looks inside Alice... Maybe that answer is how they test for psychopaths.
I guess there are two ways of passing this test: 1) use your reasoning skills to figure out the answer or 2) practice tests beforehand so you can recall the answer.
Sally puts her ball in box A and leaves. While she's away, Anne moves the ball from box A into box B. When she returns, where does Sally look for her ball?
Correctly answering this question doesn't rely on tracking where the ball is, but tracking where Sally thinks the ball is. Hence, autistic kids tend to flunk this test by answering "box B" when the correct answer is "box A".
“When Sally returns, she would look for her ball in box A, as that is where she left it before leaving. Sally is not aware that Anne moved the ball to box B while she was away.”
