postulate (and, with it, the Born rule), one must be very careful not to unwittingly, and of course invalidly, use the standard interpretation of the formalism in terms of collapses and probabilities. We will see below that much of the confusion regarding the reach of decoherence as a tool to resolve foundational questions arises from ignoring these aspects and making this type of mistakes.

The formalism described above is, of course, the most successful empirical theory ever constructed. The problem, however, is that, in spite of such an amazing predictive success, the formalism is not fully satisfactory – the culprit being the notorious measurement problem. But what is the measurement problem? Crull is right in pointing out that the measurement problem means different things to different people and that, in fact, it sometimes consists of a group of interrelated issues and not only one specific problem. She is also right in pointing out that there is a lot of confusion in the literature regarding its true nature, import and consequences. Unfortunately, we believe that the discussion of the problem in [@Crull] only deepens the misunderstanding.

The measurement problem is, of course, a problem of a theoretical framework. Therefore, in order
