The paradox of trust is akin to the choice between Type I and Type II errors. Should the procedural constraints of trust be set so narrowly that desirable agency behavior is deterred or so flexibly that inappropriate behavior is tolerated? Most often, principals equivocate: they really hope that trustees do not take their instructions too literally yet simultaneously fear that they will not.
