title: Homogeneity of mind can yield heterogeneity in behavior producing emergent collaboration in groups.
abstract: The evolved psychological process for producing social norms is both needed to facilitate emergent group-level traits and capable of delivering such a process. I discuss how this process can work to generate group-level traits and how specific mechanisms established to buttress social norms similarly can explain how group-level traits are supported.
