pronouns don’t create dimorphic behaviors, dimorphic behaviors create pronouns

as long as you have bifurcated signs at the root, people are always going to reduce their reference to the most generic sign because its heuristic value is most efficient, and compression is the whole point of these signs in the first place

or in fewer words, most polymorphic gender pronouns are feminine

more base types might have heuristic value depending on the feature dimensionality, where reduction yields declining value — there may even be human groups where 3 is useful, but it’s not arbitrarily large N
