      "statement": "# Bell: the EPR paradox and limits of local theories\n\n## The question\n\nCould quantum correlations be explained by a suitable underlying local hidden-variable theory? Bell's 1964 work converts this foundational question into constraints that can be compared with quantum predictions. A hidden variable is an additional proposed description of the system; locality and the other assumptions specify how outcomes are allowed to depend on the experiment. Those assumptions are part of the result, not optional background decoration.\n\n## The idea\n\nRather than asking only which philosophical picture sounds convincing, derive an inequality that every model in the specified class must satisfy. If a competing description predicts correlations outside that constraint, the two descriptions have an observable disagreement. The theoretical inequality and later experiments testing related constraints are different contributions. The 1964 paper should not receive automatic credit for every subsequent experimental design, loophole analysis or measurement.\n\n## Why it matters\n\nThe contribution makes a conceptual disagreement susceptible to mathematical and experimental analysis. WRS's S grade highlights that change in the research question. Its current field label is a presentation aid, not a declaration that foundational physics belongs to only one discipline. Neither an editorial grade nor a model's confident summary independently verifies the theorem or the applicability of a particular experimental test.\n\n## A teaching example\n\nImagine two separated boxes that each produce an answer when given a setting. Before looking at any output, write down what information each box may use and whether the settings can depend on shared earlier information. Different permitted-information rules define different model classes. A table of answers may then rule out one class while leaving another untouched. This is only an analogy for the importance of assumptions; it is not a Bell experiment, and a toy table cannot establish a physical violation or faster-than-light communication.\n\n## Scope and a useful next step\n\nRead the original theoretical source and keep any experimental paper as a separate reference. A manageable contribution would compare the assumptions of one inequality with the conditions reported in one experiment. Identify which assumption each check addresses, and what remains unresolved. An observed correlation does not by itself explain a mechanism or permit signaling. If a source is unavailable behind an archive browser check, record that access boundary rather than claiming a fresh full-paper verification.\n\n## Scientific scope\n\nAssumptions such as locality must be retained. The theoretical result and subsequent experiments are distinct contributions.\n\n## Sources for this explanation\n\n- [Bell, On the Einstein Podolsky Rosen paradox, Physics 1 (1964) 195–200](https://cds.cern.ch/record/111654?ln=en): Identified original contribution source. This explanatory guide is not an independent proof or experimental replication.\n",
