Abstract

Roberts and Sherratt argue that if agents with identical tags are allowed a choice of behaviour, then tag similarity can no longer be a reliable guide to behaviour and so similarity does not breed cooperation. Although they are correct in noting that in our model1 an agent will always donate when it meets another with an identical tag, we do not believe that their basic claim is correct.
