Objection: Payoff matrix is rigged by Gauthier Gauthier obviously designed his x payoff matrices to have nash equilibrium corners and cooperative corners, with the payoffs arranged such that cooperation is desirable. But a payoff matrix need not look like this, and if it doesn’t then gauthier’s approach to morality falls apart. Neither party has a dominant strategy thus, there are no nash equilibrium or cooperative corners. Trying to ascertain whether people are risk adverse or risk attainers Row plays top row then they get 5 no matter what. Plays bottom, then you have a chance at all or nothing PD games do have nash equilibrium and cooperative corner they are the defining characteristics of a PD game...they always will have those if not, then you are not playing pd. Gauthier is interested in PD games because they model a specific kind of interaction between people where an agreement is made to cooperate to the benefit of both parties, but the actual fulfillment of the agreement is to occur at a later date, and so there’s risk involved with cooperating (that is, fulfilling the agreement) – you never know how conscientiously the other person will fulfill their half of the agreement. Business people find themselves in situations where an agreement is made but you wonder if the agreement will be kept.
