Stephen Wagner of about.com has punished the article 7 Signs of Poltergeist Activity. (Click on link for full article) Beyond being a fun read there is little new information accept the point that poltergeist activity is different from a true haunting. Unfortunately Wagner misses the point and misses the opportunity to make an important observation. He writes “poltergeist activity is the result of psychic energy generated (usually unconsciously) by a person” or psychokinesis but those “persons” are generally young females between the ages of 10 to 25 who are going through puberty. This is plausible reason that an unusually high number of High Schools are reputed to be haunted. Historically, the Salem witch trials involved a group teenage girls having extraordinary fits, things thrown, pinching and other events considered beyond what was normal. Today the whole of the events have been generalized as hoaxes and mass hysteria, but looking at the described happenings it would be easy to also ascribe poltergeist activity to some of the accounts.
