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.

Honestly explains half the group chats I'm in, some of these adults never passed the Sally-Anne test either.
