Theory of Mind
Theory of mind (ToM) is the ability to understand that other people hold beliefs, desires, intentions, and perspectives different from one's own — to infer what's in other people's "minds." It's what lets someone understand that another person can hold a false belief, that intentions drive behavior, and that other people see the world from different angles.
The hypothesis that autistic people have difficulty with theory of mind was proposed by Simon Baron-Cohen, Alan Leslie, and Uta Frith in 1985. Later research showed the relationship is more complex: many autistic people do develop ToM — especially for explicit tasks — but differently or more slowly. The difficulty may lie more in fast, implicit processing of social information than in a total inability.
Critiques of the ToM concept in autism: Damian Milton's "double empathy problem" proposes that the difficulty of mutual understanding is bidirectional — neurotypical people also struggle to understand autistic perspectives.
💡 Practical example
In the classic "false-belief test": Joana puts a chocolate in a box and leaves the room. Pedro comes in and moves the chocolate somewhere else. When Joana comes back, where will she look for the chocolate? Most 4-year-olds answer correctly (where Joana put it). Autistic children often answer based on where the chocolate actually is now — not on Joana's perspective (her false belief).
