Consequence of the interaction of two cognitive states for the same experiments. Cognitive states gain information on the outcome of an experiment always through the macroscopic environment. The macroscopic environment is submitted to tiny fluctuations in the interval. The experimenter obtains information on the state of the experimental device either "directly" or through other sources such as the interaction with another observer Nevertheless agreement between these different sources must be respected. It can be demonstrated that only two positions are stable: "expected" results and observed results are either always concordant (θ = +π/4) or always discordant (θ =-π/4). See text for details on calculations. Eight examples of computing of the probability to observed concordant pairs are shown in this figure (at each iteration, a very small elementary change of probability of concordant pairs is applied in this computer simulation: from0.5 to +0.5 × 10-15 ).
