A reader suggests the Statistical Interpretation of quantum mechanics, aka the Ensemble interpretation, is superior to others.
My main complaint is that this claims to be a "minimalist interpretation". It is not. Sometimes the many-worlds also claims to be minimalist. It is not either. The most minimal of the of the mainstream interpretations is the Instrumentalist interpretation.
The statistical interpretation essentially says that only probabilities are observable, and only in large systems. But quantum mechanics is commonly used to make predictions about small systems, such as a the energy levels of a 2-particle hydrogen atom. Turning this into a statistical observation about an ensemble of hydrogen atom is to add a lot of extraneous junk. A minimalist interpretation has to say something about one atom.
I prefer the positivist interpretation, as being truly minimalist.
Probability is a mathematical layer with multiple interpretations, and any quantum mechanics interpretation that requires probability is not minimalist.
Part of the confusion is that people think that probability is essential to quantum mechanics, via the Born rule. Probability is important to quantum mechanics in the same way that it is important to other scientific theories, but not essential.
