Use this to request in-text attribution or an inline citation for perspectives and opinions that the Wikipedia article asserts is held by someone, but you don't know who holds the view.
If the material is supported by a citation to a reliable source, then look at the source to find out who holds the view, rather than adding this tag to the sentence.
Do not demand in-text attribution for simple, non-controversial facts. Simple facts, like "The Earth is round", should not be attributed to one person, because that attribution implies that very few people agree with the statement. In-text attribution is normally reserved for minority views, controversial claims, and other widely disputed material.
Controversial, poorly sourced perspectives and opinions in biographies of living persons should be deleted immediately, without moving it to the article's talk page.
If you have reason to think that these perspectives and opinions are not attributable to anyone by a reliable source, you may remove them altogether. Optionally, paste them into the article's talk page and explain your reasoning of why they should be removed.
If you know who the perspectives and opinions can be attributed to: Please be bold, delete the template, and indicate who they are attributed to, either in the text or with a citation.
