Many worlds or one: reply to Steeger
摘要
Steeger (Synthese 200(2), 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.
