 We stress that, according to the above scheme, quantum mechanics makes only conditional probabilistic predictions (conditional on the measurement being actually performed) for the outcomes of prospective (and in general incompatible among themselves) measurement processes. Only if a state belongs to an eigenmanifold of the observable, which is going to be measured, already before the act of measurement, one can predict the outcome with certainty. In all other cases—if the completeness assumption is made—one has objective nonepistemic probabilities for different outcomes.
