You seem to imply that Jaynes was writing before Bell. That is not true by many decades. I suppose it is possible that the chapter is based on a paper he wrote before Bell, but he had half a century to revise it.
Jaynes thought he had found an error in Bell's theorem, but he was wrong. (I wrote a comment somewhere on LW about this before; I'll link to it as soon as I find it.)
I'm under the impression that he was so committed to the idea that there are no probabilities due to intrinsic indeterminacy of nature rather than our ignorance that he got mind-killed. (I wonder whether he had ever heard (and seriously thought) about the MWI.)
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
