Sorry I was wrong before. I think what you&amp;#x27;re talking about here is what gets called the &amp;quot;detection loophole&amp;quot; in most of the literatire. The idea that if we detect only a small enough fraction of the events then they can be a sufficiently unrepresentative sample that we think we violated a Bell inequality even though the full statistics don&amp;#x27;t. This has (in my opinion) been comprehensively addressed already. You can check out the references in the section of the wiki article here…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/1508.05949/"&gt;Paper and discussion history&lt;/a&gt;.

About the link between boole&amp;#x27;s and bell&amp;#x27;s inequalities : There are tons of paper : A quick search for example https://arxiv.org/pdf/quant-ph/0406004.pdf (I just skimmed it for a few seconds but it&amp;#x27;s probably talking about the right thing) In the paper you suggest https://arxiv.org/abs/1508.05949, there is nothing which looks like a probability definition. Assuming the world is using continuous fields, defining the probability for what register as a discrete event like a &amp;quot;blip&amp;quot; must be done carefully, it&amp;#x27;s not a trivial…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/1508.05949/"&gt;Paper and discussion history&lt;/a&gt;.

In fact they seem to me to be completely different. Boole&amp;#x27;s inequality also does not tell you &amp;quot;you&amp;#x27;re doing the math wrong when defining your measure&amp;quot;, it tells you that the probability that either A or B happens is not greater than the sum of the probability of A happening and the probability of B happening. I&amp;#x27;m not sure what you mean in the first part of your comment, could you indicate specifically what probability measure is defined…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/1508.05949/"&gt;Paper and discussion history&lt;/a&gt;.

Proponents of realist interpretations of QM have relied for decades on identifying possible classical channels of relativistic communication, or theorizing the existence of hidden variables. The double slit experiment has been used in various forms to, over time, eliminate these channels. I&amp;#x27;m not a physicist, but the language that they are using quite a few papers leads me to believe that these channels have been closed, and the realists are out of remaining…&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/1508.05949/"&gt;Paper and discussion history&lt;/a&gt;.
