measurement problem present in the literature, Crull decides to use the one in [@Sch]. According to Schlosshauer’s book, the measurement problem is composed of three distinct parts:

1.  *The problem of the preferred basis*. What singles out the preferred physical quantities in nature – e.g., why are physical systems usually observed to be in definite positions rather than in superpositions of positions?

2.  *The problem of the nonobservability of interference*. Why is it so difficult to observe quantum interference effects, especially on macroscopic scales?

3.  *The problem of outcomes*. Why do measurements have outcomes at all, and what selects a particular outcome among the different possibilities described by the quantum probability distribution?

Schlosshauer argues that decoherence resolves the first two components and the first part of the third one (i.e., why measurements have outcomes at all). He also claims that it is debatable whether it solves the last bit of the third one since it is linked to the choice of interpretation. In any case, he claims that this last element of the problem is only of “philosophical” relevance and not important for practical purposes.

At any rate, given our previous discussion regarding the nature of the measurement problem, it
