Most universes you can describe don’t break up nicely into Everett branches. My point was that in between having two of you in one branch and having one each in two, there are many less well divided worlds in which your two copies have complicated relationships (you can go between them smoothly, though its not informative). It seems like you should also make predictions in these intermediates.

Can’t we define an operator counting the number of humans and enumerate its eigenstates, at least in principle?
