Operator-Related Anomalies in a Random Mechanical Cascade
Abstract—Experiments with a "Random Mechanical Cascade" (RMC) apparatus have yielded anomalous results correlated with pre-stated intentions of human operators. Based upon a common statistical demonstration device, this machine allows 9000 polystyrene balls to drop through a matrix of 330 pegs, scattering them into 19 collecting bins with a population distribution that is approximately Gaussian. As the balls enter the bins, exact counts are accumulated photoelectrically, displayed as feedback for the operator, and recorded on-line. Operators attempt to shift the mean of the developing distributions to the right or left, relative to a concurrently generated baseline distribution. Of the 25 operators who have completed one or more experimental series with this device, four have achieved anomalous separations of their right and left efforts, and two others have displayed
significant separations of either their right or left efforts from their baselines." --
