In this paper we discuss and re-analyze some phenomena involving interactions between machines and states of conscious intention that have been reported by Robert Jahn and his colleagues at Princeton University. We specifically deal with the experiments these investigators have carried out using an apparatus called the random mechanical cascade (or RMC). We introduce a class of theories, called selection theories, which might be invoked to explain the phenomena they have observed. These include some parapsychological theories that have been proposed for such phenomena in the past, and they also include the theory that the phenomena are spurious by-products of conscious or unconscious editing of the experimental data.

We have found that the data for the RMC experiments have some statistically significant features which have not been noted before, and which tend to rule out selection theories as possible explanations of the observed phenomena. Thus our findings support the conclusion that these phenomena represent a genuine anomaly, and they narrow down the range of possible theories that might account for this anomaly.
