-The above plot shows the empirical Schelling diagrams for both Cleanup (A) and Harvest (B) (from [[2]](https://arxiv.org/abs/1803.08884)). These diagrams show the payoff that an individual agent can expect if it follows a defecting/exploitative strategy (red) vs a cooperative strategy (blue), given the number of other agents that are cooperating.  We can see that an individual agent can almost always greedily benefit from detecting, but the more agents that defect, the worse the outcomes for all agents.
