Wikipedia:Citation needed

The {{citation needed}} template aims to promote accountable discourse.

To ensure that all Wikipedia content is verifiable, anyone may question an uncited claim by inserting {{citation needed}} (or the short versions: {{cn}}, {{fact}}), or a similar inline template.

Example: Most people believe in ghosts.^{[citation needed]}

This tag signals you to do the following:

Exercise caution when relying upon unsourced claims.
If you have reason to think that the claim is inaccurate, you may remove the claim altogether. Optionally, paste it into the article's talk page and explain your reasoning.
If you can locate a reliable source for the claim: Please be bold and replace the template with <ref>some footnote</ref>, replacing some footnote with enough information to locate the source. Leave the copyediting to someone else, or learn more at Wikipedia:Citing sources.
Controversial, poorly sourced claims in biographies of living persons should be deleted immediately.
