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.

EVP are probably the most prolific results produced by paranormal investigations. There are good things about this, and there are bad things. The bad news is that, working under the assumption evidence of the paranormal is a rarity, with so many examples of EVP populating the internet, the likelihood any of it being genuinely "paranormal" is pretty low.

Orb Study #2

During a recent investigation of a private residence, Pacific Paranormal Investigations (PPI) captured this particulate "orb" on our infrared surveillance cameras. PPI presents this short video clip as part of our ongoing community outreach and education program.
