I consider Katherine Hawley's commitment account of interpersonal trustworthiness alongside her sceptical challenge regarding the value of philosophically modelling institutional trustworthiness as distinct from reliability. I argue, pace Hawley's challenge, that there would be significant diagnostic and explanatory loss if we were to content ourselves with ideas of institutional (un)reliability alone; and I offer an illustrative case where institutional unreliability is only the half of it, indicating that when it comes to certain kinds of institutional dysfunction, we do need philosophical (...) models of institutional ‘distrustworthiness’ if we are to achieve a proper diagnosis.
