"Knowledge" in Psi-Epistemic Interpretation Fundamental or Emergent?

[QUOTE="lucas_, post: 6222563, member: 543935"] Is "Knowledge" in quantum Psi-Epistemic interpretation fundamental or emergent? And what does it mean? What do you think? [URL unfurl="true"]https://backreaction.blogspot.com/2019/08/the-problem-with-quantum-measurements.html[/URL] "One way to deal with the measurement problem is to argue that the wave-function does not describe a real object, but only encodes knowledge, and that probabilities should not be interpreted as frequencies of occurrence, but instead as statements of our confidence. This is what’s known as a “Psi-epistemic” interpretation of quantum mechanics, as opposed to the “Psi-ontic” ones in which the wave-function is a real thing. The trouble with Psi-epistemic interpretations is that the moment you refer to something like “knowledge” you have to tell me what you mean by “knowledge”, who or what has this “knowledge,” and how they obtain “knowledge.” Personally, I would also really like to know what this knowledge is supposedly about, but if you insist I’ll keep my mouth shut. Even so, for all we presently know, “knowledge” is not fundamental, but emergent. Referring to knowledge in the postulates of your theory, therefore, is incompatible with reductionism. This means if you like Psi-epistemic interpretations, you will have to tell me just why and when reductionism breaks down or, alternatively, tell me how to derive Psi from a more fundamental law."
