Trust that seems purely moral actually supervenes on prior shared interests.

Evidence

In the case of the putative supervenience on interests of a trust that is not seemingly based in interests, we can actually give an account of how to get from a relationship grounded in interests to one that is seemingly unmoored. Our problem with the account is that people may often deny that there was ever a background of interests. The problem of psychological supervenience is more that of the agent than of the theorist who wishes to explain the agent’s behavior. This is a problem that is rife in social explanation. Our task is not simply to accept agents’ testimony but, for example, to establish general patterns of development of trust relationships. — Russell Hardin, Trust and Trustworthiness, 418
