The accuracy of quoted material is paramount and the accuracy of quotations from living persons is especially sensitive. To ensure accuracy, the text of quoted material is best taken from and cited to the original source being quoted. If this is not possible, then the text may be taken from a reliable secondary source ideally one that includes a citation to the original. No matter where you take the quoted text from, it is important to make clear the actual source of the text, as it appears in the article.
Partisan secondary sources should be viewed with suspicion as they may misquote or quote out of context. In such cases, look for neutral corroboration from another source. Any analysis or interpretation of the quoted material, however, should rely on a secondary source see WP:No original research.
A statement that all or most scientists or scholars hold a certain view requires reliable sourcing that directly says that all or most scientists or scholars hold that view. Otherwise, individual opinions should be identified as those of particular, named sources. Editors should avoid original research especially with regard to making blanket statements based on novel syntheses of disparate material. Stated simply, any statement in Wikipedia that academic consensus exists on a topic must be sourced rather than being based on the opinion or assessment of editors.
Review articles , especially those printed in academic review journals that survey the literature, can help clarify academic consensus. How accepted, high-quality reliable sources use a given source provides evidence, positive or negative, for its reliability and reputation. The more widespread and consistent this use is, the stronger the evidence. For example, widespread citation without comment for facts is evidence of a source's reputation and reliability for similar facts, whereas widespread doubts about reliability weigh against it. If outside citation is the main indicator of reliability, particular care should be taken to adhere to other guidelines and policies, and to not represent unduly contentious or minority claims.
The goal is to reflect established views of sources as far as we can determine them. Some sources may be considered reliable for statements as to their author's opinion, but not for statements asserted as fact. For example, an inline qualifier might say "[Author XYZ] says A prime example of this is opinion pieces in sources recognized as reliable.
When using them, it is best to clearly attribute the opinions in the text to the author and make it clear to the reader that they are reading an opinion. Otherwise reliable news sources—for example, the website of a major news organization—that publish in a blog-style format for some or all of their content may be as reliable as if published in standard news article format. There is an important exception to sourcing statements of fact or opinion: Never use self-published books, zines , websites, webforums, blogs and tweets as a source for material about a living person , unless written or published by the subject of the biographical material.
Breaking-news reports often contain serious inaccuracies. As an electronic publication, Wikipedia can and should be up to date, but Wikipedia is not a newspaper and it does not need to go into all details of a current event in real time. It is better to wait a day or two after an event before adding details to the encyclopedia, than to help spread potentially false rumors.
This gives journalists time to collect more information and verify claims, and for investigative authorities to make official announcements. The On the Media Breaking News Consumer's Handbook  contains several suggestions to avoid spreading unreliable and false information, such as distrusting anonymous sources and unconfirmed reports, as well as reports attributed to other news media; seeking multiple sources; seeking eyewitness reports; being wary of potential hoaxes, and being skeptical of reports of possible additional attackers in mass shootings.
Claims sourced to initial news reports should be immediately replaced with better-researched ones as soon as they are published, especially if those original reports contained inaccuracies. When editing a current-event article, keep in mind recentism bias. These templates should not be used, however, to mark articles on subjects or persons in the news; if they were, hundreds of thousands of articles would have such a template, but to no significant advantage see also Wikipedia:No disclaimers in articles.
