Many worlds or one: reply to Steeger

Abstract

Steeger (2022) has recently claimed that Bohmians are able to make use of the Deutsch-Wallace derivation of quantum-mechanical chance values. I argue that Steeger's proposal does not succeed, but a close cousin of it - for de Broglie-Bohm epistemic probabilities - does. This clarifies the relationship between Born rule probabilities in Everettian quantum mechanics and de Broglie-Bohm theory, as well as the scope of the Deutsch-Wallace theorem
