skeptical inquiry

Debunking: Frequently misused to refer to the search for practical causes of paranormal events and anomalies, the term "debunking," is reserved for the unmasking of bunco, or "bunk," those paranormal confidence tricks used by charlatans to swindle customers out of their money. The preeminent "debunker" of the 20th century was James Randi, a former stage magician turned investigator bent on exposing unscrupulous mentalists, prestidigitators, fortune tellers, spoon benders, psychics, and mystics. In 1996, Randi created the James Randi Educational Foundation (JREF) for skeptical enquiry, and famously offered one million U.S. dollars to the first person who could demonstrate a valid supernatural ability while undergoing scientific testing. To date, no one has passed the first level of the test.
