Individuals are randomly matched to play an ex-ante symmetric hawk-dove game. Individuals assume one of a finite set of observable labels and condition their action choice on their opponent’s label. We study the evolutionary stability of chosen labels and their social interaction structure. Evolutionarily stable social structures differ for games in which a dove player prefers the opponent to play hawk (anti-coordination games), and those in which everyone prefers their opponent to play dove (conflict games). Non-trivial hierarchical social structures can only emerge in anti-coordination games. Egalitarian social structures can emerge in both, but are more fragile in conflict games.
