Is it the same thing as the copenhagen interpretation, what's different about it?
That's true as well - and you are only exaggerating a bit.Well, it seems they still add new flavors to the Copenhagen interpretations. Overexaggerating it a bit: There are as many Copenhagen interpretations as quantum physicists subscribing to that interpretations :).
It would be helpful if you would tell us the context in which you encountered the phrase. I expect that you found it in the Leifer paper ("Is the quantum state real? A review of ψ-ontology theorems") to which you were referred earlier? If so, Leifer provides a definition, and if you have follow-up questions based on this definition you will have to be more precise about which parts you need help with.Is it the same thing as the copenhagen interpretation, what's different about it?
