There is no testable mathematical model of either Everett’s branches, or quantum immortality, so it is pointless to argue about the evidence for or against, unless you are a tenured professor who is paid to do so.
Forget testability, there is not even a way to set up reasonable priors and make a Bayesian estimate. The Everett-based models are not less wrong, they are not even wrong.

Eliezer’s take on those objections:
Decoherence is Simple
Decoherence is Falsifiable and Testable
Quantum immortality is quite another can of worms, and there’s not as much of a LW consensus on the way anthropic probabilities work.
