a Expected payoffs given the perceived benefit effect. b Probability of cooperation given the perceived benefit effect. Note: γ = 0.4, Cg = 3 − α ∙ (g − 1), where Cg is the payoff from mutual cooperation for group g. The parameter α > 0 measures how much from the original value is subtracted when moving to the next group. α = 0.1 is used in the model
