In chapter 6, I discuss falling in love and into friendship as ways in which trust comes quickly, virtually before any interaction. What often happens, however, is that people grow into a richer relationship of friendship or at least cooperativeness with respect to some range of matters. At that point, trust may often be overdetermined because trustworthiness is overdetermined. You may be trustworthy out of interest, morality, and friendship. You may even develop a simple disposition to be trustworthy to me, and you might develop a disposition to trust me. (Such dispositions toward particular persons could be shattered by misunderstanding or bad faith.)

XREF: Connects to the relationship between trust, friendship, and morality — parallels other accounts of trustworthiness being reinforced by multiple independent grounds.
