Entropic dynamics: a hybrid-contextual model of quantum mechanics

Abstract
The Bell–Kochen–Specker (BKS) theorem and the more recent \(\psi \)-epistemic no-go theorems of Quantum Mechanics (QM) are discussed in the context of entropic dynamics. In doing so we find that the BKS theorem allows for, a perhaps overlooked, hybrid-contextual model of QM in which one set of commuting observables (position in this case) is non-contextual and all other observables are contextual. Entropic Dynamics is in a unique position as compared to other foundational theories of QM because it derives QM using standard techniques in Bayesian probability theory. In this formalism, position is the preferred basis from which inferences about other contextual operators are made. This leads to the interpretation that Entropic Dynamics is a hybrid-contextual model of QM, which we show to be consistent with the BKS theorem and QM.
