Sorry for being a pain, but I didn’t understand exactly what you said. If you’re still an active user, could you clear up a few things for me? Firstly, could you elaborate on counterfactual definiteness? Another user said contrafactual, is this the same, and what do other interpretations say on this issue?
Secondly, I’m not sure what you meant by the whole universe being ruled by hidden variables, I’m currently interpreting that as the universe coming pre-loaded with random numbers to use and therefore being fully determined by that list along with the current probabilistic laws. Is that what you meant? If not, could you expand a little on that for me, it would help my understanding. Again, this is quite a long time post-event so if anyone reading this could respond that would be helpful.
Firstly, I am not an expert in QM, so you should take everything I say with a whole serving of salt.
1) Yes, counterfactual = contrafactual. What other interpretations of QM say about counterfactual definiteness I don’t know. But wikipedia seems to give at least a cursory understanding to what is necessary for any interpretation to QM.
2) You could understand it that way, yes. Basically, the existence of hidden variables means ‘just’ that our current theory of QM is incomplete. So basically there is no collapsing wave function or decoherence or anything and all the seeming randomness we observe just comes from our not knowing which values those hidden variables take.
Again, if all I have said is complete and utter nonsense, please correct me!

Also not a QM expert, but this matches my understanding as well.
