Article is self contradictory re locality

Intro says experimental results are incompatible with local hidden variable theories, but Manyworlds section says Bell's doesn't apply and it is a dynamically local theory. This is clearly inconsistent with the intro. Suggest intro be changed to "*most* local hidden variable theories" Joncolvin (talk) 16:48, 31 October 2024 (UTC)[reply]

No. Hidden worlds don't seem to count as "hidden variables". So all local hidden variables are incompatible. Johnjbarton (talk) 17:16, 31 October 2024 (UTC)[reply]

The MWI (or rather, all the various versions of it proposed over the years) is not a hidden-variable model. In a hidden-variable model, either a wavefunction is a probability distribution over the true physical states, or the hidden variables exist in addition to the wavefunction. In MWI, the wavefunction is physical reality. XOR'easter (talk) 22:15, 31 October 2024 (UTC)[reply]
