Macroscopic Unobservability of Spinorial Sign Changes
  In Section 5 of Christian (2014), published in IJTP, an experiment is described which is purported to have the capacity for exhibiting quantum correlations in a completely classical environment. Unfortunately the experiment has an interesting self-destructive property: it is certain not to deliver the required result, hence it is pretty certain that no experimenter will ever bother to perform it.
