Jaynes has reservations about Bell's Theorem, and they made a fair amount of sense to me. And in general I find it good policy to trust him on how to properly interpret probabilistic reasoning.

If you're going to use an authority heuristic, at some point you also have to apply the heuristic "what does pretty much everyone else think?"

My impression is that most people take for granted that Bell was correct, and consider it a done deal. Another impression is that "pretty much everyone else" mistakenly takes ontological randomness as a conceptual given on a macro level, and there has yet to be conclusive evidence (see detector efficiency) that ontological randomness operates on a micro level.

I'm not saying he is right. I'm saying that I haven't seen any better probabilistic analysis of the issue than what I've seen from Jaynes, and the evidence so far doesn't conclusively prove him wrong.

Well, maybe my complaint about authority is just be hindsight talking. This is because it's not like entanglement has never again been part of scientific research - quantum computers are made of the stuff. Electrons are just not classical objects.

And I think that, if we treat the universe as based on causality (a la Judea Pearl), the hidden variable route ( P(A | B a b) = P(A | a b) ) really is the only relativistic one, if we avoid many worlds. There are three ways for events to be linked: direct causally linked (faster than light), both descendants of a node we know about (hidden variable), or both ancestors of a node we know about (faster than light).
