Eleanor March: 'Is the Deutsch-Wallace theorem redundant?'
I defend the Deutsch-Wallace (DW) theorem against a dilemma presented by Dawid and Thebault (2014), and endorsed in part by Read (2018), and Brown and Porath (2020), according to which the theorem is either redundant or in conflict with general frequency-to-chance inferences. I argue that neither horn of the dilemma is well-posed. On the one hand, the DW theorem is not in conflict with general frequency-to-chance inferences on the most natural way of stating the theorem. On the other hand, the DW theorem is crucial for establishing the Born rule as a prediction of Everettian quantum mechanics, and so cannot be redundant within the theory.
The PoP-grunch (Philosophy of Physics Graduate Lunch) is a weekly informal seminar in which graduate students in Philosophy of Physics present their work in progress. Anyone can attend although please note that Meeting Room 4 is limited to 12 people. Anyone interested in presenting or being added to the mailing list should contact Dominik Ehrenfels dominik.ehrenfels@wolfson.ox.ac.uk.
