Quantum effects in belief. Can comp explain this?
I have not the time look at that definition of belief, but actually
(this is not a confession, I have already explain this, but probably
not so lately) a consequence of the loss of the necessitation make the
comp quantum logic into a belief theory (in the sense of Dempster-
Shafer).
Comp is close to Fuch and Pauli and Heisenberg: the wave describes
relative belief state.
But I have stop to look at those who see the quantum directly in term
of beliefs, as it does not fit well neither comp nor the quantum, it
is only "quantum" in a very weak sense.
Now, why do you keep asking me if comp can explain this or that, when
my contribution is that comp leads to the *necessity* of explaining
matter from mind, and mind from arithmetic?
I submit a problem, translate it in arithmetic, and begun to solve it.
You might ask yourself can "non-comp" explain this., but that might be
trivial in the paper which I might read later, the week-end for example.
About the K paper, please notice that when you have two semantically
equivalent theory for some representation, the most informative one
will be the one with one more independent axiom. That is why S4Grz is
more interesting than S4, it provides more constraints for the class
of all models, despite both are complete and sound for intuitisonistic
logic. So only K would be very poor (in case Z1* would have collapse
into K). It would be less dramatic than getting just Classical
propositional logic, in which case physics would be empty, and all
laws of physics would be contradicted somewhere in the (still)
physical universe: everything would be geographical. With K, physics
is no more empty, but with Z1*, normally we get the whole physics
(with some help from S4Grz1, and X1*, so that many internal nuances
are possible. Also the Z and X logics are graded (which is welcome),
and as I realized recently, finding an arithmetical interpretation of
the dyodorean formula <>[]p -> []<>p in the Z1* logic, might make
sense, and even gives some hope to justify dimensionality, relation
between knots and space (and gravitation).
It just hard to interview the machine on GR and compare.

In recent years, quantum probability theory has been used to explain
a range of seemingly irrational human decision-making behaviors. The
quantum models generally outperform traditional models in fitting
human data, but both modeling approaches require optimizing
parameter values. However, quantum theory makes a universal,
nonparametric prediction for differing outcomes when two successive
questions (e.g., attitude judgments) are asked in different orders.
Quite remarkably, this prediction was strongly upheld in 70 national
surveys carried out over the last decade (and in two laboratory
experiments) and is not one derivable by any known cognitive
constraints. The findings lend strong support to the idea that human
decision making may be based on quantum probability.
These findings suggest that quantum probability theory, initially
invented to explain noncommutativity of measurements in physics,
provides a simple account for a surprising regularity regarding
measurement order effects in social and behavioral science.
