Self-locating uncertainty and the many worlds interpretation
Speaker(s): Kelvin McQueen
Abstract: According to the many worlds interpretation (MWI), quantum mechanics in its simplest form (no collapse or hidden variables) is complete. A primary objection to the MWI is that it fails to account for the Born rule. The most prominent response to this objection comes from the decision-theoretic program, which aims to derive a rationality postulate according to which a believer in the MWI ought to act as if the Born rule is true. I argue that the existence of alternative coherent rationality postulates undermines this response. A different response, based on self-locating uncertainty, avoids this objection and may explain the Born rule in the MWI. I conclude by considering whether this framework is capable of explaining the weak trace of particles in certain difficult cases.
