honoring the heroes of

skeptical inquiry

Haunting: In common parlance, when a location exhibits a pattern and a personality of paranormal activity, it is said to be "haunted." As a rule, PPI does use this word, nor do we enter into any investigation assuming that a haunting is occurring; rather, it assumes that paranormal activity is not occurring and, instead, looks for practical reasons or causes. If our findings cannot be explained, we prefer instead to classify a case as "unexplained." Phenomena associated with classic "haunting" are generally identified as Intelligent or Residual. Claims of an "intelligent haunting" are characterized by a sentience who is "attached" to the premises and interacts with it and its living occupants. Characteristics typical of a so-called "residual haunting" are rote and absentminded, as if caught in a repeating loop. A third classification, Poltergeist, remains controversial; although it resembles a haunting, it is thought by many to be a manifestation of a living mind; in consequence, it has more in common with possession, with which it suffers from similar lack of credibility.
