Anomalous operation

Anomalous operation, also known as anomalous perturbation, is a term describing a broad category of purported paranormal effects that can best be described as subject A stating an intent or goal to influence system B, and system B then changing appropriately through unknown or unverifiable means. System B can be literally anything, though the common experiment is one or more subjects working to influence the output of a random system such as an electronic noise source. It covers phenomena as psychokinesis, micro-psychokinesis, pyrokinesis, faith healing, poltergeist activity, and other manipulative parapsychological phenomena.
