[SPK] I strongly disagree with this statement! Everett showed
the exact opposite; that relative probabilities completely depend
of the choice of basis and framing.
Prove? This is contrary to what Everett said, and I have try to
contradict him on this, eventually he is right. Deustch tought like
you but has eventually change its mind. There are no prefer basis,
and with the CTM there are not even a prefer ontological theory.
Dear Bruno,
Is it possible to define a "relative probability" in the case
where it is not possible to count or otherwise partition the members
of the ensemble?
Yes. "relative probability" is not necessarily a constructive notion.
Not that I know of! If you know how, please explain this to me!
Normally if you follow the UDA you might understand intuitively why
the realtive probability are a priori not constructive. So you can't
use them in practice, but you still can use them to derive physics,
notably because the case "P = 1" can be handled at the proposition
level through the logic of self-references (Bp & Dt, p sigma_1).
