 The final step of the proof our Bell-type theorem is to exhibit a system, a quantum mechanical state, and a set of quantities for which the statistical predictions violate inequality (8). The example used by Bell stems from Bohm’s variant of the EPR thought-experiment (Bohm 1951, Bohm and Aharonov 1957). A pair of spin-\(\frac{1}{2}\) particles is produced in the singlet state,
