Wikipedia:Citation needed

Innovative application for the template in xkcd 285 (Wikipedian Protester)
The {{Citation needed}} template aims to promote accountable discourse.

To ensure that all Wikipedia content is verifiable, anyone may question an uncited claim. If your work has been tagged, please provide a reliable source for the statement, and discuss if needed.

You can add a citation by selecting from the drop-down "cite" menu at the top of the editing box. In markup, you can add a citation manually using ref tags. There are also more elaborate ways to cite sources.

In wiki markup, you can question an uncited claim by inserting a simple {{Citation needed}} tag, or a more comprehensive {{Citation needed|reason=Your explanation here|date=November 2019}}. Alternatively, {{fact}} and {{cn}} will produce the same result. These all display as:

Example: 87% of statistics are made up on the spot.[citation needed]

"Citation needed" statements are part of the historical number of tags).

When to use this tag

A "citation needed" tag is a request for another editor to verify a statement: a form of communication between members of a collaborative editing community. It is never, in itself, an "improvement" of an article. Though readers may be alerted by a "citation needed" that a particular statement is not supported, many readers don't fully understand the community's processes. Not all tags get addressed in a timely manner, staying in place for months or years, forming an ever growing Wikipedia backlog—this itself can be a problem. Best practice recommends the following:

  • Tag thoughtfully. Avoid "hit-and-run" or pointed tagging. Try to be courteous and consider the hypothetical fellow-editor who will, we hope, notice your tag and try to find the citation you have requested. When adding a tag, ask yourself: Is it clear just what information you want cited? Is the information probably factual? (If it is not, then it needs deletion or correction rather than citation!) Is the knowledge so self-evident that it really does not need to be cited at all? (Some things do not.)
  • Some tags are inserted by people well placed to find a suitable citation themselves. If this is the case, consider adding these articles to your watchlist or a worklist so that you can revisit the article when you have the opportunity to fix the verifiability problems yourself.
