 Often, in popular writings, the case of aligned devices is the only one mentioned, and the perfect anticorrelation (for spin-\(\frac{1}{2}\) particles in the singlet state) or correlation (for photons in state \(\ket{\Phi}\)) of results in this case is offered as evidence of “spooky action at a distance.” In fact, as Bell (1964, 1966) demonstrated by means of simple toy models, this behaviour can be reproduced by entirely local means. An important insight of Bell’s was to consider the less-than perfect correlations obtained when the device axes are not aligned. In Bell’s toy model, correlations fall off linearly with the angle between the device axes, whereas the quantum correlations (14, 16) fall off sinusoidally; the decrease in correlations away from the case of perfect alignments is less steep than in the toy model. Bell’s theorem shows that this sort of behaviour is not a peculiarity of his model; no model satisfying the condition F can reproduce the quantum correlations for all angles. This can be seen by considering the quantum predictions (14, 16) and plugging them into the expression for \(S\). For a pair of spin-\(\frac{1}{2}\) particles in the singlet state, we have,
