Obviously, refusing to give in the public goods game reduced the reputation of a player to a similar extent as if this person had refused to give in the indirect reciprocity game: his potential donor in the next round of indirect reciprocity just followed the rules for indirect reciprocity and refused to give to someone with a low image score. This is different from punishing because it does not need any special punishing rule or motivation, and the potential donor actually saves money by refusing to give. — Hans-Jürge, Reputation helps solve the `tragedy of…, 28
