Does anyone know how Wheeler understood QM? Here are some well-known sayings of his (slightly paraphrased): "the wave function does not represent the electron- it represents what we know about the electron; the joint product of all the evidence that is available to those who communicate" "it is meaningless to talk about the position of a particle until a position measurement has been performed. No question- no answer!" He also often quoted Bohr: "no phenomenon is a phenomenon until it has been made macroscopic by an irreversible act of amplification" He seems to be treading a very confusing middle ground between realism and operationalism. On the one hand, he clearly does not take the wf as the "actual reality", as MWI, BM, collapse models, and even the Von Neumann/Wigner consciousness idea would have it. On the other hand, he does see observations, or "acts of observer/participancy" as playing a special- and very real- role; so much so that he went on to suggest that our observing the universe is necessary for its existence("it from bit")! I'm not asking about that particular idea; I just want to know whether his interpretation of QM is seen today as a self-consistent possibility, and if so, how to make sense of it.
