Abstract: Everettian quantum mechanics (EQM) might appear to be inhospitable to metaphysical indeterminacy (MI), given that, as Alastair Wilson (2020) puts it, “the central idea of EQM is to replace indeterminacy with multiplicity” (77). But as Wilson later observes, the popular decoherence-based understanding of EQM (DEQM) appears to admit of MI in world nature. After sketching DEQM (S1), we bolster the case for there being MI in world nature in DEQM (S2). The question remains of how to account for this MI. After briefly describing the two main contenders—a metaphysical supervaluationist approach as per Barnes and Williams (2011), and a determinable-based approach as per Wilson (2013) and Calosi and Wilson (2018 and forthcoming)—we offer four arguments in support of a determinable-based approach’s having a clear comparative advantage so far as accommodating MI in world nature in DEQM is concerned (S3).
