    Incidentally, I notice that besides this entry Bell’s inequalities we have Bell’s theorem, and the two should be merged.

    Looking over the latter, I find that the text offered there needs attention. (This originates from a user 12+ years ago who caused us some trouble back then, I seem to remember.)

    I won’t do the merging right now, though (am on my phone in a plane descending onto Dubai…).

    I have added an Idea-section and a full statement and proof of the inequality.

    (Have not yet added the argument for why/how this inequality is violated in QM.)

    As announced there, I have merged the material previously at Bell’s theorem into here, in order to merge the duplicate entries.

    That original material had references to equation numbers coded by hand(!), which I have now adjusted to automatic numbering, hoping I got it all right.

    (A strange technical glitch is that in the original entry all the equations were numbered automatically, while in the new entry the numbers appear only for equations that also carry a label. While that clearly makes sense, I am puzzled that the rendering can change just by copying material to another entry as if dependent on some preamble context, which I thought doesn’t exist for nLab entries(?).)
