 It may sound odd to insist that trustworthiness is a virtue or, in other words, a moral disposition to be trustworthy (Potter 2002: 25; Hardin 2002: 32). What disposition exactly is it meant to be? A disposition normally to honor people’s trust? That would be strange, since trust can be unwanted if the trust is immoral (e.g., being trusted to hide a murder) or if it misinterprets the nature of one’s relationship with the trustee (e.g., being trusted to be friends with a mere acquaintance). Perhaps trustworthiness is instead a disposition to respond to trust in appropriate ways, given “who one is in relation” to the trustor and given other virtues that one possesses or ought to possess (e.g., justice, compassion) (Potter 2002: 25). This is essentially Potter’s view. Modeling trustworthiness on an Aristotelian conception of virtue, she defines a trustworthy person as “one who can be counted on, as a matter of the sort of person he or she is, to take care of those things that others entrust to one and (following the Doctrine of the Mean) whose ways of caring are neither excessive nor deficient” (her emphasis;  16).[6]  A similar account of trustworthiness as a virtue—an epistemic one, specifically—can be found in the literature on testimony (see Frost-Arnold 2014; Daukas 2006, 2011).
