 Folk psychology is a name traditionally used to denote our everyday way of understanding, or rationalizing, intentional actions in mentalistic terms. This quotidian competence is known by other names in the philosophical literature: commonsense psychology; naïve psychology; Homo sapiens psychology; the person theory of humans; the intentional stance; propositional attitude psychology; belief-desire psychology (see, e.g., Churchland 1979; Dennett 1987; Goldman 2006; Bogdan 2009). As some entries on this list suggest, folk psychology can be conceived of in wider or more narrow terms, picking out different extensions accordingly.
