Sensible Quantum Mechanics: Are Probabilities only in the Mind?

Abstract

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}.
