Overview

MinutePhysics, with 3Blue1Brown, explains Bell's theorem using a Venn diagram paradox and polarizing filters. It shows why no local hidden variable theory can reproduce quantum correlations.

On Hacker News

Repeatedly recommended as the most accessible explanation of Bell's inequality, reducing it to a simple counting problem.

I really enjoyed this Minute Physics and 3Blue1Brown video describing hidden variables and Bell's theorem: [VIDEO] As you said, it's implies that we're not failing to measure some "hidden variable" that would explain probabilities away, but that the vary nature of these objects is probabilistic.

Part of this is because of tests like the ones involved with Bells theorem. Minute physics does a better job explaining it then I can. [VIDEO]

I can also suggest a video that seemed to me to explain Bell's theorem and what it means that the correlations are stronger than classically possible here: [0] [VIDEO]
