Extended Data Fig. 6: Graphs of size N≤10 that most easily support prosocial behavior.

For PC and DB updating, we illustrate the 100 graphs with the lowest positive critical ratios for pp- and ff-goods. In each case, the graphs are colored according to their critical ratios. In these examples, ff-goods result in lower critical ratios than pp-goods, and DB updating tends to give lower ratios than PC updating.
