This template tag will categorise tagged articles intoCategory:Articles that may contain original research. Thistemplate is aself-reference and so is part of the Wikipedia project rather than the encyclopedic content.
The intention of this tag is tonudge fellow editors who may inadvertently (or otherwise) introduce text thatappears based upon original research, into supporting such text through demonstrating its previously researched origins. This tag provides agood faith means for editors to allow given text of fellow editors to remaintemporarily in a given article until such time as the text's previously researched origins are supported. In the event that researched origins for the text are not produced after a relatively small passage of time (i.e., no more than a few days), the tagging editor would generally be right in assuming that it could be edited or otherwise removed from the article to comply withWikipedia:No original research. When a given editor adds this template they must concurrently add corresponding text to the tagged article's talk page to explain their concerns relative to original research for the given tagged text unless talk already exists relative to such concerns. If a given article has been tagged and the tagging editor doesn't ensure that corresponding article talk relative to the tag isn't either already available or added within a short amount of time (i.e., no more than 24 hours) then fellow editors are within their rights to remove the tag or alternatively, add talk in support of its use.
