Reasonable Rules of Choice

Players have consonant interests if each has a strategy favourable to the pursuit of his own and the
interests of the others when the latter adopt a best response. Reasonableness is to move according to such
a strategy at the stage reached, reaping the gains this generates. Some overt games hide an underlying
game in the choice of rules of choice in which reasonableness is substantively rational, credible and leads
to a state that Pareto dominates the Nash equilibria of the original game. The paper contains an application
to the finite prisoner’s dilemma
