Is the wave function, an unreal tool, to partially model a real interaction?

    Is the wave function, an unreal (but a useful mathematical) tool, to partially model a real interaction?

    i.e. can probabilities have an existence of their own? i.e. exist by themselves without referring to some underlying phenomena?

    The wave function is a mathematical/probability tool. It is certainly a very useful tool.

    However is the wave function a tool to model some real interaction/resource we don't know much about yet?

    What does the wave-function tell us about this "unknown but real" interaction/phenomena?

    Psi-Epistemic Theories: The Role of Symmetry

    No-go theorems for ψ-epistemic models based on a continuity assumption

    but as stated by Rudolph (epistemic proponent):
    "Even though it seems very abstract, what we're saying in some sense is tied to space and time,"

    "I prepare this, and then I measure that, and so on. So although it comes in very implicitly, I think that ultimately what we will understand is that space and time are just part of what this particular primate has evolved to find a use for – that what's actually going on in the universe doesn't care about space and time."

    IMO exist various pure quantum states corrrespondent/consistent with only one ontic state
    Epistemic-Ontic reality, i.e. wave functions are epistemic and there is some underlying ontic state.

    in contrast in the Epìstemic-Epistemic scheme there is no underlying reality
    or the Ontic proposition in which the wave function is the reality.

    above from this discussion in these forums:

    The quantum state cannot be interpreted statistically?
