 In Section 4.2 we briefly discussed the role of the study of knowledge and belief when analyzing social procedures. In this vein, the field of epistemic game theory focuses on agents’ beliefs about other agents’ strategies and those agents’ beliefs about other agents’ strategies, and so on, up to the idealized case of common knowledge among a group of agents that they are all rational (see the entry on  epistemic foundations of game theory;  Perea 2012; Brandenburger 2014).
