The Limits of Influence is a detailed examination and defense of the evidence for largescale-psychokinesis. It examines the reasons why experimental evidence has not, and perhaps cannot, convince most skeptics that PK is genuine, and it considers why traditional experimental procedures are important to reveal interesting facts about the phenomena.

A critical review is conducted based on analytical simulations of an experimental study to measure change in weight of sheep upon death published in 2001 by L. E. Hollander in JSE. The experimental system is modeled as a single-degree-of-freedom vibrating system. The following conclusions are obtained. (1) The experimental result obtained with Sheep #7 appears to be natural, as expected by the theoretical model. (2) Hollander’s conclusion that “there was a transient gain of weight of 780 grams” in the case (...) of Sheep #7 is not an appropriate expression of the experimental result, because the 780 gf pulse includes an overshoot reaction of the system; however, the cause of the force event remains to be explained. Analytical simulation of a supposed weight measurement experiment involving an out-of-body experience (OBE) subject is carried out using the theoretical model under a supposed weight decrease of the experient. The simulation showed that the disturbance caused by breathing becomes the primary noise in the system response. However, some noise reduction techniques can be used to discern the change in the weight of the experient, if there indeed is a weight decrease. Weight measurement experiments using a trance channeler are suggested because “trance channeling” is objectively more observable than OBE.
