This thread is getting a lot longer and more involved than I anticipated. Apologies but for the sake of my own free time and sanity I may have to slow down and make more use of citations. The main point I was trying to get across was that QBism does say these things about quantum theory, regardless of whether or not you find it tenable. As I say the mathematics is invariant across interpretations, therefore the Born rule and POVMs have a use to an Everettian just as they do a QBist. The difference is what they think of the physical meaning of such a thing. [0][1] Interpreting quantum theory…

Perhaps it would help to note that in QBism, reality is not denied. Rather, the objective reality of the quantum state is denied. Not sure what you mean by incompatible results. Certainly QBism is incompatible with Many Worlds! The latter states that the quantum state is real and objective, the former states the opposite. The QBist horsemen have devoted some attention to the question of compatible quantum state assignments. See: https://arxiv.org/abs/quant-ph/0206110 However, Chris Fuchs does not see any problem in someone assigning a probability-1 belief to a measurement outcome and being…
