Everettian rationality: defending Deutsch's approach to probability in the Everett interpretation
Abstract
An analysis is made of Deutsch's recent claim to have derived the Born rule from decisiontheoretic assumptions. It is argued that Deutsch's proof must be understood in the explicit context of the Everett interpretation, and that in this context, it essentially succeeds. Some comments are made about the criticism of Deutsch's proof by Barnum, Caves, Finkelstein, Fuchs, and Schack; it is argued that the flaw which they point out in the proof does not apply if the Everett interpretation is assumed.
