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

<p>Left: Resulting outcome as a function of the relative benefit <i>B</i>/<i>A</i> of showing the preferred behavior and the relative strength <i>S</i> of population 1 for the model parameters <i>R</i> = 10, <i>r</i> = 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 <i>p</i><sub>1</sub> and <i>p</i><sub>2</sub> to the respectively preferred behavior in both populations for the model parameters <i>A</i> = 1, <i>B</i> = 0.5, R = 10, <i>r</i> = 0.01, and <i>S</i> = 0.5.</p>
