There is a general agreement that most quantum systems exhibit a strong form of quantum metaphysical indeterminacy (QMI). This means that QMI is almost a given, intrinsic property of a quantum system S, and it does not depend on external elements such as the environment E of S and the scale at which S is defined. This paper aims to qualify this statement: there are several ways to interpret QMI based on multiple factors: different interactions with the environment (hence, decoherence), the way we interpret the formalism of QM, and ultimately the structure of spacetime in which S is embedded. If classical systems do not display QMI, then where do we make the cut between indeterminacy and determinacy? This suggests that QMI may sit at the end of a spectrum. IF Quantum Mechanics is a ‘non-final theory’ (Ruetsche, Bell) do we expect to have an absolute QMI grounded in its formalism? We explore this suggestion further by stating that when decoherence is considered, the much-celebrated QMI becomes relational (relative to an environment) and hybrid (as a limiting case of a quantum and classical system). The paper also explores a form of epistemicism about quantum mechanics that is usually considered instrumentalism or anti-realism and may deflate the strength of the arguments for an absolute QMI. The idea of bringing QFT as a more fundamental theory that can resolve or dissolve some of the QMI at the level of QM is briefly stated. Is it also of interest to talk about indeterminacy in Quantum Gravity and how it relates to QMI.","language":"5.
