“…Probably the idea is motivated by the EPR definition of "elements of physical reality". Fortunately, contrary to widespread beliefs [29][30][31][32][33], the original Bell inequality formulation requires neither counterfactual definiteness nor counterfactual reasoning [22].…”

We present a pragmatic analysis of the different meanings assigned to the term ``local realism'' in the context of the empirical violations of Bell-type inequalities since its inception in the late 1970s. We point out that most of them are inconsistent and arise from a deeply ingrained prejudice that originated in the celebrated 1935 paper by Einstein-Podolski-Rosen. We highlight the correct connotation that arises once we discard unnecessary metaphysics.

“…Indeed, the correct inequality derivation exclusively relies on the results of actually performed experiments (cf. [21,22], also Appendix 5.2). Hence, it cannot falsify whether those results existed or not previous to measurements.…”

“…Therefore, a coherent rejection of realism as a "causal explanation" has nothing to do with the infamous elements of physical reality or logically ill-conceived machinations such as counterfactual definiteness, incompatible experiments, or joint probabilities [22].…”

“…Probably the most popular version is the CHSH inequality [17]. References [18][19][20][21][22] discuss the CHSH inequality correct and incorrect derivations warning against the use of counterfactual reasoning. The derivation of the Bell inequality requires only elementary mathematics and is uncontroversial from the mathematical point of view.…”

The alleged nonlocal character of quantum mechanics is inextricably related to the formulation of the Bell theorem. However, as we shall see, that relation is commonly incorrectly assessed. The departure from the clear line of reasoning that John Bell tried to convey has led to a polarization of part of the scientific community into radical irreconcilable positions. We show how the correct appreciation of Bell's work calls for reinterpreting the usual significance given to the Bell theorem yielding a more rational perspective of the problem. Given the relevance of the Bell-type inequalities in quantum information technology and quantum foundations, further clarification of their relation to the nonlocality conundrum deserves due attention. The exposition is also of didactic value. It shows the problems arising from incorrect inferences and superfluous metaphysical ideas.
