Dear Hans,
Thank you for mentioning QBism. It can be treated as the quantum alternative
for classical Bayesian inference.
In this connection, it is good to mention that classical Bayesian PU suffers of
the well known Cromwell problem: if prior probability is zero it would always
be zero,
if it is 1 it always be 1...
Quantum update of probability does not suffer of this problem, zero probability
can be updated to nonzero, the same can happen for the probability one.
See our paper in attachment, it was published in Journal of Mathematical
Psychology.
yours, andrei

Subject: [Fis] A curious tale and QBism
Thank you Pedro for mentioning my new book.
Actually, there is a connection between my book and the curious tale. QBists
look at the future as a web of interlaced personal, numerical probability
estimates, with no certainties anchored in REAL mechanisms. The probability
that CERN will blow up the world is small enough to be negligible for most
people, but not for all. The thing QBists reject as in principle unattainable
is ABSOLUTE certainty, which many lay people and some physicists (Einstein was
among them) continue to long for.
