honoring the heroes of

skeptical inquiry

Explaining Paranormal Activity: Since PPI strives to honor the scientific method and promote skeptical inquiry of paranormal phenomena, the term "explain" is preferred over the word "debunk." While the term "debunking" is still frequently used, many conscientious paranormal groups are moving away from the term because it is does not dignify the motive of most clients who request investigations. The term derives from bunkum, an insincere public display or statement, which suggests that debunking a paranormal phenomenon means to expose the trickery of duplicitous clients. Such clients are an extreme rarity for investigation groups. "Debunking," in fact, entered into the popular vernacular because of criminal investigators and scientists who, in the interest of protecting the unwitting public, apprehended charlatan spirit mediums, defrauded psychic flimflam, and exposed medical quackery. One of the most famous debunkers who has evolved from a professional illusionist into one of the leading figures of skeptical inquiry is James Randi. The preferred term among paranormal investigators these days is "explaining," which is far more empathetic to the possibility that a client in paranormal distress may have misunderstood or overlooked a rational explanation for paranormal activity, rather than have conspired to dupe the public.
