Phase diagrams illustrating how the finally resulting system behavior depends on the parameter choices and on the initial conditions.

Left: Resulting outcome as a function of the relative benefit B/A of showing the preferred behavior and the relative strength S of population 1 for the model parameters R = 10, r = 0.01. Three different cases (“phases”) are possible, as indicated in the figure: either the great majority of people shows the individually preferred behavior (grey), or the behavior preferred by population 1 is established as a norm (white), or alternatively the behavior of preferred by population 2 (black). Right: Resulting outcome as a function of the initial average commitments p₁ and p₂ to the respectively preferred behavior in both populations for the model parameters A = 1, B = 0.5, R = 10, r = 0.01, and S = 0.5.
