ABSTRACT
Recurrent spontaneous psychokinesis (PK) or poltergeist activity used to be attributed to spirits, but is now sometimes associated with a particular human, often an adolescent. Most spiritual traditions are associated with some form of PK, from healing the sick to apparent miracles like the biblical story of the parting of the Red Sea. Poltergeist cases have been reported on occasion for at least 500 years. Typical features include objects moving for no apparent reason, sometimes breaking, and unexplained noises such as knocking. in 1955, Lambert found that half of the fifty odd cases he studied were within a few miles of tidal water and that more cases were reported in winter. Random number generator or random event experiments have become the main way of testing for PK. Radioactive decay and electronic noise form the basis for true random number generators; an alternative is to use a complicated computer algorithm which generates a pseudo-random series.
