No probability loophole in the CHSH

Abstract

Geurdes (2014) outlines a probabilistic construction of a counterexample to Bell’s theorem. He gives a procedure to repeatedly sample from a specially constructed “pool” of local hidden variable models (depending on a table of numerically calculated parameters) and select from the results one LHV model, determining a random value S of the usual CHSH combination S of four (theoretical) correlation values. He claims Prob(|S|>2)>0. We expose a fatal flaw in the analysis: the procedure generates a non-local hidden variable model. To disprove this claim, Geurdes should program his procedure and generate random LHV’s till he finds one violating the CHSH inequality.
