Abstract

'In the ontological models framework [Harrigan & Spekkens 2007], it is assumed that the probability measure representing a quantum state is independent of the choice of future measurement setting.' (Leifer 2014, 140)

In this recently-unearthed piece I discuss a version of the above assumption, concluding that it is 'very difficult to justify on metaphysical grounds'. I note that abandoning it has an interesting potential payoff, given its crucial role in the no-go theorems of Bell and of Kochen & Specker. There has been increased interest in this option in recent years, under the label of retrocausal models of QM (see, e.g., Price & Wharton 2015, Wharton & Argaman 2020). The present piece may be of interest to diligent historians of this approach. It was written in 1978, while I was a graduate student in Cambridge.
