To summarize our progress thus far, we are considering a population of agents which are merely hosts to pairs of replicating entities, memes and genes. In game theory, the labeling and positioning of rows and columns of a payoff matrix have no effect on a game’s strategic properties, but permutations may influence the responses of human decision makers, especially in symmetric games, because symmetry is most obvious when a matrix is presented in what we call root position, as in the versions shown in Figs. 96.
