 This piece explores these different philosophical issues about trust. It deals predominantly with interpersonal trust, which arguably is the dominant paradigm of trust. Although some philosophers write about trust that is not interpersonal, including trust in groups (Hawley 2017), institutional trust (i.e., trust in institutions; see, e.g., Potter 2002; Govier 1997; Townley and Garfield 2013), trust in government (e.g., Hardin 2002; Budnik 2018) or science (e.g., Oreskes 2019), self-trust (Govier 1993; Lehrer 1997; Foley 2001; McLeod 2002; Goering 2009; Jones 2012b; Potter 2013), and trust in robots (e.g., Coeckelbergh 2012, Sullins 2020), most would agree that these forms of “trust” are coherent only if they share important features of (i.e., can be modeled on) interpersonal trust. The assumption going forward therefore is that the dominant paradigm is interpersonal.
