A New Frame for Intersubjectivity in Game Theory: The Insights of the Theories of Mind and Simulation

Chapter Chapter 5 in On Coordination in Non-Cooperative Game Theory, 2023, pp 215-281 from Springer

Abstract: Abstract Chapter 5 adopts a philosophy of economics approach to show the contribution of the theory of mind (ToM) to renew the intersubjective dimension in game theory assumed with common knowledge rationality. With ToM, we show in this chapter that empathy is not confined to an ethical dimension (involved in other-regarding feelings and behaviors) but is essentially linked to cognitive and epistemic dimensions of particular interest for game theory. In ToM, empathy is a mechanism of mental state attribution. ToM provides an explanation of the way players may tacitly understand each other, which explains how they form beliefs toward each other’s beliefs and actions. The type of intersubjectivity supposed in game theory through CKR, while highly problematic (see Chap. 2 ), is unanimously assumed. Thus, this chapter will present the type of intersubjectivity that can be offered by the epistemic side of empathy, which is called mindreading in cognitive sciences and ToM. We show that the type of intersubjectivity assumed in mindreading is compatible with a strategic form of reasoning embedded in methodological individualism (understood in a broad sense). We suggest the simulation theory within ToM as an alternative to common knowledge of Bayesian rationality.
