Abstract: In this talk, we first present a brief review of evolution mechanisms of cooperation. Then we give a clean model with conditional dissociation only, which could be viewed as a variant of peer punishment. Supported by both the numerical simulations and the theoretical analysis of Neutrally Stable Strategy， we show that conditional dissociation does promote cooperation, no matter whether mixed strategies are allowed or not, but the pure strategies induces more cooperation. Moreover cooperative behavior is favored when waiting time and/or the population’s lifespan are longer. We also illustrate the explanation power of our model by the stories in the real world.
