"[citation needed]" is a tag added by Wikipedia editors to unsourced statements in articles requesting citations to be added.[1] The phrase is reflective of the policies of verifiability and no original research on Wikipedia and has become a general Internet meme.[2]
The tag was first used on Wikipedia in 2006,[2] and its template created by user Ta bu shi da yu. By Wikipedia policy, editors should add citations for content, to ensure accuracy and neutrality, and to avoid original research.[3] The Шаблон:Not a typoon needed tag is used to mark statements that lack such citations.[1]Шаблон:Asof, there were more than 539,000 pages on Wikipedia (or roughly 1% of all pages) containing at least one instance of the tag.[1] Users who click the tag will be directed to pages about Wikipedia's verifiability policy and its application using the tag.[4]
Randall Munroe has frequently used "[[[:Шаблон:Not a typo]]on needed]" tags for humorous commentary in his writings, including in his 2014 book What If?[7][8][9]
It was also used as the name of a 2014–2018 YouTube series by the British comedy group The Technical Difficulties. In the show, Tom Scott gives the title of a random Wikipedia article to the other members, and they try to guess on what the rest of the article is about with a 'ding' and points for correct guesses.[10]
