The wavefunction has other branches, because it’s the same mathematical object governed by the same equations. Only, the wavefunction doesn’t exist physically, it’s just an intermediate variable in the computation. The things that exist (corresponding to the Φ variable in the formalism) and the things that are experienced (corresponding to some function of the 2Γ variable in the formalism) only have one branch.
So in a “weird experiment”, the infrabayesian starts by believing only one branch exists, and then at some point starts believing in multiple branches?
Multiple branches can only exist transiently during the weird experiment (i.e. neither before nor after). Naturally, if the agent knows in advance the experiment is going to happen, then it anticipates those branches to appear.
If there aren’t other branches, then shouldn’t that be impossible? Not just in practice but in principle.
