 Finally, the main thrust of this entry is theoretical and foundational. However, there also is a more practical aspect to logic and games. Logic plays a role in cognitive psychology and experimental game theory, if only to identify testable hypotheses related to Theory of Mind or strategic reasoning (Ghosh, Meijering, &amp; Verbrugge 2014; Ghosh &amp; Verbrugge 2018; Bicchieri 1993; Fagin, Halpern et al. 1995). Lastly, some work at the interface of logic and games suggests outreach to the world of actual parlor games (van Ditmarsch &amp; Kooi 2015; van Benthem &amp; Liu 2019).
