Nice paper (from a while back). AFAICT his resolution of the
indeterminacy issue in MWI is logically identical to Bruno's FPI in
the context of computationalism. In other words, in both cases it is
an 'illusion of ignorance' attributable to the limitation on
information available to each 'copy' of a deterministically
proliferated observer. Each copy will inevitably (and subjectively
justifiably) identify itself as a continuation of a common
'ancestor'. Each observer will therefore feel justified in making
probabilistic predictions based on its *subjective restriction* to
an apparently (but, sub specie aeternitatis, illusorilly) singular
personal history. According to Vaidman this is essentially what the
paper is about.
I'm frankly staggered that this (i.e. the equivalence between the
two forms of FPI) can be in the least controversial at this stage.
And is it?
It is ignored, but if it was controversial, I think I would know it.
It is not controversial, it is ignored, and hidden by the usual
special interest, like defending personal notoriety etc.
John Clark has illustrated perfectly well the panoply of strategies
you need to hide the FPI, by making it looking contreversed, but it is
not. Just ignored by pseudo-religious people for pseudo-religious or
private interests or both.
It is a bit like the danger of marijuana. It does not exist for any
scientists having work on the subject, so its "scientific" relative
innocuousness is not controversial. It is controversial only in
"media" and "politics".
The use of the FPI in quantum mechanics will work or not, but to work,
what I show is that not only we must get the Born rules, but we must
get the waves itself too. If not, QM becomes a religion of the gap,
and hides the mind-body problem in the (quite persisting then)
Aristotelian theological dogma.
