Sensible Quantum Mechanics: Are Probabilities only in the Mind?
Quantum mechanics may be formulated as {\it Sensible Quantum Mechanics} (SQM)
so that it contains nothing probabilistic except conscious perceptions. Sets of
these perceptions can be deterministically realized with measures given by
expectation values of positive-operator-valued {\it awareness operators}.
Ratios of the measures for these sets of perceptions can be interpreted as
frequency-type probabilities for many actually existing sets. These
probabilities generally cannot be given by the ordinary quantum
``probabilities'' for a single set of alternatives. {\it Probabilism}, or
ascribing probabilities to unconscious aspects of the world, may be seen to be
an {\it aesthemamorphic myth}.Comment: LaTeX, 14 pages, shortened version of quant-ph/950601
Possibilities for Probabilities
In ordinary situations involving a small part of the universe, Born's rule
seems to work well for calculating probabilities of observations in quantum
theory. However, there are a number of reasons for believing that it is not
adequate for many cosmological purposes. Here a number of possible
generalizations of Born's rule are discussed, explaining why they are
consistent with the present statistical support for Born's rule in ordinary
situations but can help solve various cosmological problems.Comment: 8 pages, LaTe
