Fig. 1: The types of individuals in the world.

Individuals are aware of the existence of narratives 1 and 2. They have a personal belief in either 1 or 2. The actions of the individuals could be H or S (shown as icons). Thus, the strategy of a focal individual (⋆) is defined by \(({a}_{1}^{\star },{a}_{2}^{\star },{u}^{\star })\) where \({a}_{i}^{\star }\) is the hunting strategy of the focal individual when the group chooses to collectively believe in narrative i and u^⋆ is the narrative that the individual personally believes in. Following their own narratives, the red-tinged strategies would hunt hares, and blue-tinged, stags.
