The tag "[citation needed]" is 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]
Usage on Wikipedia
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 citation needed tag is used to mark statements that lack such citations.[1] As of June 2023[update], 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]
Usage outside Wikipedia
In 2008, Matt Mechtley created stickers with "[citation needed]", encouraging people to stick them on advertisements.[5]
