+This hypothesis is weaker than the autogynephilia theory, but still has implications for the ways in which transgender identity claims might or might not be validated by natural, prediction-motivated categorization schemes. If most trans women's traits are noticeably _not drawn from the female distribution_, then it becomes less practical to insist that others categorize them as women.
+
+To this it might be objected that there are many different types of women. Clusters can internally have many subclusters: Pureto Rican women (or married women, or young women, or lesbians, _&c_.) don't have the _same_ distribution of traits as women as a whole, and yet are still women. Why should "trans" be different from any other adjective one might use to specify a subcategory of women?
+
+The problem is that—under the two-types hypothesis where gender dysphoria in non-exclusively-androphilic biological males is mostly not an intersex condition—most trans women aren't just not part of the female cluster in configuration space, displaced from it in some arbitrary direction. They're specifically part of the _male_ cluster (along most dimensions), which people _already_ have a concept for.
