A diagnosis, title, or nationality can explain something without explaining someone.

A category can be accurate and still be a summary. The diagnosis explains the pattern, the title explains the role, the nationality explains a context, and none of them tells you what someone is like on a Tuesday, what they want, or how they treat people. The label answers a question about mechanism, not about person.

When you learn a fact like this about someone, treat it as a beginning rather than an explanation. Ask what it is actually like for them. And when one is applied to you, you can accept its usefulness without accepting it as a description.
