 In the context of BDMI, SDMI and PMI it is usually claimed that, given the space of possible events, the state generates an ignorance-interpretable probability measure over this set: quantum probabilities quantify the ignorance of the observer about the actual values acquired by the system’s observables (see, e.g. Dieks 1988, Clifton 1995a, Vermaas 1999, Bene and Dieks 2002).
