The <Einstein–Podolsky–Rosen criterion of reality> says that if, without disturbing a system, one can predict a physical quantity with certainty, then an element of physical reality corresponds to that quantity.
For two settings on each wing and outcomes in $\{-1,1\}$, the <CHSH inequality> for every <local hidden-variable theory> is
$$
\boxed{|E(A_0B_0)+E(A_0B_1)+E(A_1B_0)-E(A_1B_1)|\leq2}.
