Game-theoretic modeling reveals that moderate collective reputation criteria sustain cooperation across leading-eight strategies in public goods dilemmas, highlighting the impact of social strictness.

Key Points

To examine how introducing collective reputation assessments into public goods games affects the evolution and stability of indirect reciprocity and group-level cooperation.
Developed a theoretical evolutionary game framework embedding group-level reputation assessment mechanisms into public goods games.
Evaluated the dynamical stability and performance of the 'leading-eight' reputation-based strategies across varying social assessment criteria.
Altering group assessment criteria destabilized the standard reputation dynamics of leading-eight strategies, but sustained cooperation remained achievable within a specific criteria window.
An optimal, moderately set collective assessment threshold maximized cooperative behavior and resolved the public goods dilemma.
Evolutionary preference for social strictness among leading-eight strategies was inversely correlated with the payoff level.
