 The orthodox position gives a very simple answer to the question: what determines the outcome, when different outcomes are possible? The answer is “nothing”—the theory is complete and therefore it is illegitimate to raise any question about properties possessed prior to a measurement, when different outcomes of a measurement of an observable have non-vanishing probabilities of occurring, if the measurement is actually performed. Correspondingly, the referents of the theory are only the results of measurements. These are to be described in classical terms and involve in general mutually exclusive physical conditions.
