https://www.quantamagazine.org/quantum-bayesianism-explained-by-its-founder-20150604/ The usual story of Bell’s theorem is that it tells us the world must be nonlocal. That there really is spooky action at a distance. So they solved one mystery by adding a pretty damn big mystery! What is this nonlocality? Give me a full theory of it. My fellow QBists and I instead think that what Bell’s theorem really indicates is that *the outcomes of measurements are experiences, not revelations of something that’s already there*. @philipthrift > > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
