Reliability of Wikipedia

A series of studies from Harvard Business School in 2012 and 2014 found Wikipedia "significantly more biased" than Encyclopædia Britannica but attributed the finding more to the length of the online encyclopedia as opposed to slanted editing.

[26][27] Concerns regarding readability and the overuse of technical language were raised in studies published by the American Society of Clinical Oncology (2011),[28] Psychological Medicine (2012),[24] and European Journal of Gastroenterology and Hepatology (2014).

Variations in coverage mean that Wikipedia can be both, as online communities professor Amy S. Bruckman put it, "the most accurate form of information ever created by humans" on the whole while short articles can be "total garbage".

[53][nb 2] A web-based survey conducted from December 2005 to May 2006 by Larry Press, a professor of Information Systems at California State University at Dominguez Hills, assessed the "accuracy and completeness of Wikipedia articles".

[61][62][63] In its April 2008 issue British computing magazine PC Plus compared the English Wikipedia with the DVD editions of World Book Encyclopedia and Encyclopædia Britannica, assessing for each the coverage of a series of random subjects.

[75] In 2007, Michael Gorman, former president of the American Library Association (ALA) stated in an Encyclopædia Britannica blog that "A professor who encourages the use of Wikipedia is the intellectual equivalent of a dietician who recommends a steady diet of Big Macs with everything".

"[77] PC Pro (August 2007) cites the head of the European and American Collection at the British Library, Stephen Bury, as stating "Wikipedia is potentially a good thing—it provides a speedier response to new events, and to new evidence on old items".

[90] In 2007, the Chronicle of Higher Education published an article written by Cathy Davidson, Professor of Interdisciplinary Studies and English at Duke University, in which she asserts that Wikipedia should be used to teach students about the concepts of reliability and credibility.

[97] This reinterpretation of NPOV "had meaningful consequences, turning an organization that used to lend credence and false balance to pseudoscience, conspiracy theories, and extremism into a proactive debunker, fact-checker and identifier of fringe discourse.

[100] In November 2012, judge Brian Leveson was accused of having forgotten "one of the elementary rules of journalism" when he named a "Brett Straub" as one of the founders of The Independent newspaper in his report on the culture, practices and ethics of the British press.

"[102] A 2016 BBC article by Ciaran McCauley similarly noted that "plenty of mischievous, made-up information has found its way" on to Wikipedia and that "many of these fake facts have fallen through the cracks and been taken as gospel by everyone from university academics to major newspapers and broadcasters.

[104] Slate said in 2022 that "Screenshots of vandalized Wikipedia articles, even when reverted within minutes, often have a much longer afterlife in news reports and on social media, creating the public impression that the platform is more vulnerable to abuse than it actually is.

Hoiberg focused on a need for expertise and control in an encyclopedia and cited Lewis Mumford that overwhelming information could "bring about a state of intellectual enervation and depletion hardly to be distinguished from massive ignorance".

[129] BBC technology specialist Bill Thompson wrote that "Most Wikipedia entries are written and submitted in good faith, and we should not let the contentious areas such as politics, religion or biography shape our view of the project as a whole", that it forms a good starting point for serious research but that:[130] No information source is guaranteed to be accurate, and we should not place complete faith in something which can so easily be undermined through malice or ignorance... That does not devalue the project entirely, it just means that we should be skeptical about Wikipedia entries as a primary source of information...

News stories appeared about IP addresses from various organizations such as the Central Intelligence Agency, the Democratic Congressional Campaign Committee, Diebold, Inc. and the Australian government being used to make edits to Wikipedia articles, sometimes of an opinionated or questionable nature.

But the online encyclopedia has since been hijacked by forces who decided that certain things were best left unknown... Now a website designed to monitor editorial changes made on Wikipedia has found thousands of self-serving edits and traced them to their original source.

In an article in the Times Higher Education magazine (London) philosopher Martin Cohen frames Wikipedia of having "become a monopoly" with "all the prejudices and ignorance of its creators", which he describes as a "youthful cab-drivers" perspective.

Ivor Tossell wrote: That Wikipedia is chock full of useless arcana (and did you know, by the way, that the article on "Debate" is shorter than the piece that weighs the relative merits of the 1978 and 2003 versions of Battlestar Galactica?)

In an article entitled "Seeking Disambiguation", Annalisa Merelli interviewed Catalina Cruz, a candidate for office in Queens, New York in the 2018 election who had the notorious SEO disadvantage of having the same name as a porn star with a Wikipedia page.

Particularly, the criteria for notability were criticized, with The Washington Post reporting: "Greenfield is a uniquely tricky case for Wikipedia because she doesn't have the background that most candidates for major political office typically have (like prior government experience or prominence in business).

[165] Andrew Schlafly created Conservapedia because he found Wikipedia "increasingly anti-Christian and anti-American" for its frequent use of British spelling and coverage of topics like creationism and the effect of Christianity on the Renaissance.

[168][non-primary source needed] In a September 2010 issue of the conservative weekly Human Events, Rowan Scarborough presented a critique of Wikipedia's coverage of American politicians prominent in the approaching midterm elections as evidence of systemic liberal bias.

Scarborough compared the biographical articles of liberal and conservative opponents in Senate races in the Alaska Republican primary and the Delaware and Nevada general election, emphasizing the quantity of negative coverage of Tea Party movement-endorsed candidates.

"[187] In a 2008 letter to the editor of Physics Today, Gregg Jaeger, an associate professor at Boston University,[188] has characterized Wikipedia as a medium that is susceptible to fostering "anarchy and distortions" in relation to scientific information.

Articles about the comedian Paul Reiser, British television host Vernon Kay, French professor Bertrand Meyer, and the West Virginia Senator Robert Byrd, who died on June 28, 2010, have been vandalized in this way.

The citation, however, read: "The Order of the Companions of OR Tambo in Gold—awarded to Joseph Sepp Bellend Blatter (1936–) for his exceptional contribution to the field of football and support for the hosting of the Fifa World Cup on the African continent", after the name on his Wikipedia entry was vandalized.

[231] The death of Norman Wisdom in October 2010 led several major newspapers to repeat the false claim, drawn from Wikipedia, that he was the author of the lyrics of the Second World War song "(There'll Be Bluebirds Over) The White Cliffs of Dover".

Jean-Pierre Grand asked the president of the French National Assembly and the prime minister of France to reinforce the legislation on the penal responsibility of Internet sites and of authors who peddle false information in order to cause harm.

A South American coati . In July 2008, a 17-year-old student added an invented nickname to the Wikipedia article coati as a private joke, calling them "Brazilian aardvarks ". The false information lasted for six years and was propagated by hundreds of websites, several newspapers, and even a few books published by university presses. [ 1 ] [ 2 ]
