The curse of knowledge, aka hindsight biasmajor contributor to academese is a cognitive blind spot called the Curse of Knowledge: a difficulty in imagining what it is like for someone else not to know something that you know. The term comes from economics, but the general inability to set aside something that you know but someone else does not know is such a pervasive affliction of the human mind that psychologists keep discovering related versions of it and giving it new names: egocentrism, hindsight bias, false consensus, illusory transparency, mind-blindness, failure to mentalize, and lack of a theory of mind. In a textbook demonstration, a 3-year-old who sees a toy being hidden while a second child is out of the room assumes that the other child will look for it in its actual location rather than where she last saw it. Children mostly outgrow the inability to separate their own knowledge from someone else’s, but not entirely. Even adults slightly tilt their guess about where a person will look for a hidden object in the direction of where they themselves know the object to be. And they mistakenly assume that their private knowledge and skills—the words and facts they know, the puzzles they can solve, the gadgets they can operate—are second nature to everyone else, too.
