A debunker is a person who attempts to discredit and contradict claims as being false, exaggerated or pretentious.[1] The term is closely associated with skeptical investigation of controversial topics such as U.F.O.s, claimed paranormal phenomena, cryptids, conspiracy theories, alternative medicine, religion, or exploratory or fringe areas of scientific or pseudoscientific research.

According to the Merriam-Webster online dictionary, "debunk" is defined as 1.Expose the falseness or hollowness of (a myth, idea, or belief). 2.Reduce the inflated reputation of (someone), esp. by ridicule: "comedy takes delight in debunking heroes".


The American Heritage Dictionary traces the passage of the words bunk (noun), debunk (verb) and debunker (noun) into American English in 1923 as a belated outgrowth of "bunkum", of which the first recorded use was in 1828, apparently related to a poorly received "speech for Buncombe" given by North Carolina representative Felix Walker during the 16th United States Congress (1819–1821).[2]

The term debunk originated in a 1923 novel Bunk, by American novelist William Woodward (1874–1950), who used it to mean to "take the bunk out of things."[3]

Often the term "debunkery" is not limited to arguments about scientific validity. It can also be used in a more general sense at attempts to discredit any opposing point of view, such as that of a political opponent.

He had become disturbed by the number of listeners phoning in with such flummery as tales of self-styled clairvoyants' uncannily correct forecasts. Gradually, his work as a debunker began to rival his show-business career, gathering momentum in the early 1970s, when Uri Geller caught Randi's attention."
