Repeated failure of trust forces revision, a minimal rational constraint.

Evidence

We are not wildly irrational in our optimism, however, and we will revise our optimistic hope if it proves to have been unwarranted. This is a minimally rational constraint on trust: One will not continue to trust another who repeatedly fails the trust. Moreover, we may be more optimistic toward new cases in richly structured than in anomic contexts. An account of the life of the infant child and its inherent dependency suggests the plausibility of evolutionary selection for openness that enables us later to be warily optimistic. — Russell Hardin, Trust and Trustworthiness, 360
