Back before Bell's Theorem ruled out local hidden variables, it seemed possible that (as Einstein thought) there was some more complete description of reality which we didn't have, and the quantum theory summarized incomplete knowledge of this more complete description.
EY seems a big fan of Jaynes. Has he ever specifically confronted Jayne's arguments against Bell?

Eliezer is definitely a big fan of Jaynes. I've never seen him write anything like a whole post or essay on that particular topic, but he has touched on it a few times. In general, Jaynes seems to have considered and rejected all the various interpretations of QM that were floating around in his day, on probability theoretic grounds. I did see EY in one place imply that he thinks Jaynes would have gone for the MWI, if Jaynes had ever heard about it. To the best of my knowledge, he never did.
Today's post, Quantum Non-Realism was originally published on 08 May 2008. A summary (taken from the LW wiki):
Discuss the post here (rather than in the comments to the original post).
This post is part of the Rerunning the Sequences series, where we'll be going through Eliezer Yudkowsky's old posts in order so that people who are interested can (re-)read and discuss them. The previous post was Decoherence is Falsifiable and Testable, and you can use the sequence_reruns tag or rss feed to follow the rest of the series.
Sequence reruns are a community-driven effort. You can participate by re-reading the sequence post, discussing it here, posting the next day's sequence reruns post, or summarizing forthcoming articles on the wiki. Go here for more details, or to have meta discussions about the Rerunning the Sequences series.
