No interpretation is really physics. These are more in a way metaphysics. They are not consistent with each other and yet they are commensurate with quantum mechanics. This means they are auxiliary. They generally can be lumped into two categories, those that are ψ-epistemic and those that are ψ-ontic, which in some way might reflect an undecidability issue with quantum mechanics. Examples of these for ψ-epistemic interpretations are Copenhagen, GRW or objective collapse, and those that are ψ-ontic are MWI or the deBroglie-Bohm interpretation.
