Question about discussions around quantum interpretations

[ojitojuntos]

Thank you so much for the explanation!
Guys, I recently read that objective collapse theories have been increasingly constrained. Does this mean that, indirectly, determinism has gained more plausibility over probabilistic interpretations?

No. The operationalis/instrumentalist account is probabilistic and has no objective collapse. Consistent histories is probabilistic and has no objective collapse. Recent nonmarkovian reformulations are probabilistic and have no objective collapse.

I would say it rather makes the concept of objective probability less plausible as fundamental in a theory or interpretation where you insist that measurements and expectations are physical interactions and encodings as opposed to armchair mathematical constructs and "not real".

Ie. it makes it less plausible to think that objectively inferrable ~ real/ontic

We have to wait for experiments using matter wave interferometry, to register quantum superposition on objects of 10¹² atoms at least.

Current experimental limit 10⁴

Thank you! Now, these past weeks I’ve tried to take some time off work to read a bit, but in afraid that I’m far from being able to grasp some of the concepts shared here.
I was wondering: Do QFT theories shift the balance towards a fully deterministic reading of nature vs a probabilistic one?

I tried to Google it, and learn from online sources, but the proliferation of AI articles and sensacionalista shows make it very hard to filter what is bogus and what not for a layman like me.

I even tried using AI to get a list of relevant articles, but most of them didn’t exist! Hahah

Again, I reallly appreciate your willingness to help me navigate these questions.
