 An approach that is close in spirit to Everett’s relative-state interpretation of pure wave mechanics is to simply to deny that there are any salient absolute matters of fact about the properties of physical systems or the records, experiences, and beliefs of observers and insist that all physical facts relevant to explaining our experience are relative (see Saunders, 1995, 1997, and 1998, Conroy 2012, and  relational quantum mechanics  for examples of how this might work). In the experiment above, a relational formulation of quantum mechanics would not describe the observer \(J\) as believing that his result was “spin up” and it would not describe him as believing that his result was “spin down”. Rather, there would be no simple fact of the matter regarding what result \(J\) recorded. Here \(J\) recorded that his result was “spin up” relative to \(S\) being x-spin up and \(J\) recorded that his result was “spin down” relative to \(S\) being x-spin down. Similarly, the state of \(S\) is x-spin up relative to \(J\) believing that his result was “spin up”, etc. On this reading of Everett, physical facts are essentially relative, and there are, hence, typically no simple matters of fact about the properties of any individual physical system.
