Epistemic Separability and Everettian Branches: A Critique of Sebens and Carroll

We discuss the proposal by Sebens and Carroll to derive Born rule in Everettian quantum mechanics from a principle they call ‘ESP-QM’. argue that fails: ESP-QM is not, as argue, ‘less general version’ of an independently plausible principle, ESP, can only be motivated empirical success mechanics, including use rule. Therefore, cannot have status meta-theoretical reasoning provides no viable basis for deriving
