  Recently, a group of experiments tested local realism with random choices
prepared by humans. These various tests were subject to additional assumptions,
which lead to loopholes in the interpretations of almost all of the
experiments. Among these assumptions are fair sampling, no signaling, and
faithful reproduction of a Bell-type quantum model. We examined the data from 9
of 13 experiments and analyzed occurring anomalies in view of the above
assumptions. We conclude that further tests of local realism need better setup
calibration to avoid apparent signaling or necessity of the complicated
underlying quantum model.
