We emphasize the difficulties of an experiment that can definitely discriminate between local realistic hidden-variables theories and quantum mechanics using the Bell CHSH inequalities and a real measurement apparatus. In particular, we analyze some examples in which the noise in real instruments can alter the experimental results, and the nontrivial problem to find a real “fair sample” of particles to test the inequalities.
