-How weasely am I being with these "approximately true" and "as a first approximation" qualifiers and hedges? I claim: not _more_ weasely than anyone who tries to reason about psychology given the knowledge and methodology our civilization has managed to accumulate. Psychology is very complicated; every human is their own unique snowflake, but it would be impossible to navigate the world using the "every human is their own unique _maximum-entropy_ snowflake; you can't make _any_ probabilistic inferences about someone's mind based on your experiences with other humans" theory. Even if someone were to _verbally endorse_ something like that—and at age sixteen, I might have—their brain is still going to go on to make predictions inferences about people's minds using _some_ algorithm whose details aren't available to introspection. Much of this predictive machinery is going to be instinct bequeathed by natural selection (predicting the behavior of conspecifics was very useful in the environment of evolutionary adaptedness), but some of it is the cultural accumulation of people's attempts to organize their experience into categories, clusters, diagnoses. (The cluster-learning capability is _also_ bequeathed by natural selection, of course, but it's worth distinguishing more "learned" from more "innate" content.) No one matches any particular clinical-profile stereotype _exactly_, but the world makes more sense when you have language for theoretical abstractions like ["comas"](https://slatestarcodex.com/2014/08/11/does-the-glasgow-coma-scale-exist-do-comas/) or "depression" or "bipolar disorder" or "autogynephilia".
