 Trust can be rational, then, depending on whether one conceives of rationality as truth-directed or end-directed. Notice that it matters also how one conceives of trust, and more specifically, whether one conceives of it as a belief in someone’s trustworthiness (see  section 4).  If trust is a belief, then whether the rationality of trust can be end-directed will depend on whether the rationality of a belief can be end-directed. To put the point more generally, how trust is rationally justified will depend on how beliefs are rationally justified (Jones 1996).
