ABSTRACT

Kenneth Arrow [1994, p. 8] As noted in Chapter 9, many game theorists see a direct connection between evolution and social learning. While some game theorists are interested only in the question of how all individual players learn to play the same equilibrium strategy whenever there are multiple equilibria possible, evolutionary game theorists seem to go further. If all individuals in equilibrium models possessed the same knowledge (as in the case of the assumption of ‘common knowledge of rationality’ discussed in Chapter 4), then equilibrium models would seem plausible although it does beg the question of how that knowledge was ‘acquired’ or better, why do they have the same knowledge. If one presumes that induction is possible, then perhaps whenever everyone faces the same facts they will induce the same knowledge. But, as I have repeatedly stressed, there is no inductive logic and thus no means of assuring such unanimity.
