PROJECT MWhat is your preferred definition of trust? In “Can We Trust Trust?” you defined trust as a particular expectation we have with regard to the likely behavior of others.” Elsewhere, you offer “trust is our expectation that another person (or institution) will perform actions that are beneficial or at least not detrimental to us, regardless of our capacity to monitor those actions.”
Diego GambettaThe first one is too generic, the second one is a little better. An even better one is to be found in the paper with Michael. When can we say we trust someone? When we expect them to do Y, a certain action beneficial to us, even when there is Z, another action which, if they are strictly self-interested, they may prefer to do and would be damaging for us. For this expectation to be trust, both truster and trustee must know that by trusting, the truster gives the trustee an opportunity to do Z. That is, I give you the money because I believe you will return it, but I am also giving you the opportunity to pocket it. If the trustee is untrustworthy and does Z, then the truster would have done better for himself by not trusting.
