Summary and Keywords
Trust is the expectation that one’s interests be looked after despite the possibility of exploitation by the one being trusted (trustee). Trusting always involves some risk on the part of the one trusting (truster). The truster is vulnerable—either by choice or by circumstance. One can never be absolutely sure that one’s interests are important to the trustee or that their past performance can allow one to predict future behavior. The trustee retains their agency and even has an incentive for betrayal in the future. Much of the research on trust in international relations is aimed at explaining cooperation amid anarchy. In this context, cooperation begins with a leap of faith by actors who trust generally rather than specifically. Such “generalized trusters” do not require evidence that the trustee in question is even trustworthy with respect to a particular issue, since all actors are assumed to be worthy of trust across all topics (assuming they have the capacity to act). This can be considered “credulity,” and it primarily involves having trustful attitudes, affects, emotions, or motivational structures that are not focused on specific people, institutions, or groups. Furthermore, one cannot speak of trust without some reference to affect, particularly since one can never absolutely calculate the odds of betrayal.
