The idea of Ballentine’s interpretation is that the wavefunction is a tool to compute a probability distribution. Probability distributions are real. Ballentine would accuse many worlders of confusing the map (wavefunctions) for the territory.
You never predict “this is what happens when I send a photon through the slit”- instead you predict “this is what happens when i send lots of photons through a slit.” Its very much the minimal interpretation of quantum mechanics. I recommend skimming through Ballentine’s text (its a very good for many reasons- deriving the Schroedinger equation from galilean relativity, for instance).
Sampling mechanism, please.
If it isn’t “They’re all real, and we just feel one of them”, then it’s adding something big—a whole new dynamical principle.
If it IS “They’re all real, and we just feel one of them”, then hey, it’s just MWI with another name.
