A debunker is a person who attempts to expose or discredit claims believed to be false, exaggerated or pretentious.[1] The term is often 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, to "debunk" is defined as:

  1. To expose the falseness or hollowness of (a myth, idea, or belief).
  2. To reduce the inflated reputation of (someone), esp. by ridicule: "comedy takes delight in debunking heroes".

If debunkers are not careful, their communications may backfire – increasing an audience's long-term belief in myths. Backfire effects can occur if a message spends too much time on the negative case, if it is too complex, or if the message is threatening.[2]

Etymology

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 County, North Carolina" given by North Carolina representative Felix Walker during the 16th United States Congress (1819–1821).[3]

The term debunk originated in a 1923 novel Bunk, by American journalist and popular historian William Woodward (1874–1950), who used it to mean to "take the bunk out of things."[4]

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

Backfire effects

<templatestyles src="Module:Hatnote/styles.css"></templatestyles>

The authors of the Debunking Handbook warn that a failed debunking can actually worsen misconceptions. They recommend simple, positive, and emotionally sensitive education (e.g. bolstering the learner's ego, or avoiding threatening words).

Australian Professorial Fellow Stephan Lewandowsky[5] and John Cook, Climate Communication Fellow for the Global Change Institute at the University of Queensland (and author at SkepticalScience.com)[6] co-wrote Debunking Handbook,[2] in which they warn that debunking efforts may backfire. Backfire effects occur when science communicators accidentally reinforce false beliefs by trying to correct them.

Cook and Lewandowsky offer possible solutions to the backfire effects as described in different psychological studies. They recommend spending little or no time describing misconceptions because people cannot help but remember ideas that they have heard before. They write "Your goal is to increase people's familiarity with the facts."[2][7][8] They recommend providing fewer and clearer arguments, considering that more people recall a message when it is simpler and easier to read. "Less is more" is especially important because scientific truths can get overwhelmingly detailed; pictures, graphs, and memorable tag lines all help keep things simple.[2][9]

The authors write that debunkers should try to build up people's egos in some way before confronting false beliefs because it is difficult to consider ideas that threaten one's worldviews[2][10] (i.e., threatening ideas cause cognitive dissonance). It is also advisable to avoid words with negative connotations.[2][11] The authors describe studies which have shown that people abhor incomplete explanations – they write "In the absence of a better explanation, [people] opt for the wrong explanation". It is important to fill in conceptual gaps, and to explain the cause of the misconception in the first place.[2][12] The authors believe these techniques can reduce the odds of a "backfire" – that an attempt to debunk bad science will increase the audience's belief in misconceptions.

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."
