One way to think about these ideas about identity and roles is in the context of a more general theory I want to suggest: that there is a recurring set of conditions under which of games of costly signaling of the ability to resemble prototypes of a category tend to evolve convergently.
Such a theory might be consistent with the results from experiments on attractiveness of facial symmetry and facial averageness.
It might also be consistent with some observations I make by introspecting on intuitions which predict social penalties for unusual but morally harmless behavior. (E.g. the penalties one would receive if one were to wear, without explanation, a formal business suit with details somehow precisely matching the accidents of fashion of a randomly and fairly drawn alternate history from 200 years ago, instead of a formal business suit with details precisely matching the accidents of fashion of our own local history.)

Such a theory would predict that there would be literature on a cognitive bias to prefer prototypical and central members of a category to non-prototypical and peripheral members of the category. But as far as I know, there is not very much specific literature on this question. The only specific literature I know of is work) by Jamin Halberstadt of the University of Otago (NZ) and co-authors about visual attractiveness. A summary from 2006 is “The generality and ultimate origins of the attractiveness of prototypes”. “Prototypes are attractive because they are easy on the mind” is an ungated paper from 2006 that reports an experiment controlling for the effect of preference for fluently processed stimuli, because prototypical stimuli are processed more fluently. (One possible interpretation of the result is that there may be a reason to prefer stimuli which aren’t confusing, because confusing stimuli may hide defects better.) “The face of fluency: Semantic coherence automatically elicits a specific pattern of facial muscle reactions” generalizes part of this effect to non-visual stimuli, and “Uniting the tribes of fluency to form a metacognitive nation” argues that fluency experiences affect many dimensions of social judgement.
