These policies jointly determine the type and quality of material acceptable in Wikipedia articles, and because they work in harmony, they should not be interpreted in isolation from one another.
Achieving what the Wikipedia community understands as neutrality means carefully and critically analyzing a variety of reliable sources and then attempting to convey to the reader the information contained in them fairly, proportionately, and as far as possible without editorial bias.
Biased information can usually be balanced with material cited to other sources to produce a more neutral perspective, so such problems should be fixed when possible through the normal editing process.
Remove material when you have a good reason to believe it misinforms or misleads readers in ways that cannot be addressed by rewriting the passage.
The internal structure of an article may require additional attention to protect neutrality and to avoid problems like POV forking and undue weight.
[a] It may also create an apparent hierarchy of fact where details in the main passage appear true and undisputed, whereas other segregated material is deemed controversial and therefore more likely to be false.
Pay attention to headers, footnotes, or other formatting elements that might unduly favor one point of view or one aspect of the subject.
Watch out for structural or stylistic aspects that make it difficult for a reader to fairly and equally assess the credibility of all relevant and related viewpoints.
Undue weight can be given in several ways, including but not limited to the depth of detail, the quantity of text, prominence of placement, the juxtaposition of statements, and the use of imagery.
However, these pages should still appropriately reference the majority viewpoint wherever relevant and must not represent content strictly from the minority view's perspective.
This rule applies not only to article text but to images, wikilinks, external links, categories, templates, and all other material as well.
However, when reputable sources contradict one another and are relatively equal in prominence, describe both points of view and work for balance.
For example, a description of isolated events, quotes, criticisms, or news reports related to one subject may be verifiable and impartial, but still disproportionate to their overall significance to the article topic.
When there is a consensus of opinion on scientific matters, providing an opposite view without consideration of "due weight" can lead to "false balance", meaning that viewers might perceive an issue to be more controversial than it actually is.
While it is important to account for all significant viewpoints on any topic, Wikipedia policy does not state or imply that every minority view, fringe theory, or extraordinary claim needs to be presented along with commonly accepted mainstream scholarship as if they were of equal validity.
There are many such beliefs in the world, some popular and some little-known: claims that the Earth is flat, that the Knights Templar possessed the Holy Grail, that the Apollo Moon landings were a hoax, and similar ones.
When writing about a topic, basing content on the best respected and most authoritative reliable sources helps to prevent bias, undue weight, and other NPOV disagreements.
If you need help finding high-quality sources, ask other editors on the talk page of the article you are working on, or ask at the reference desk.
Wikipedia deals with numerous areas that are frequently subjects of intense debate both in the real world and among editors of the encyclopedia.
Pseudoscientific theories are presented by proponents as science but characteristically fail to adhere to scientific standards and methods.
This applies to all types of fringe subjects, for instance, forms of historical negationism that are considered by more reliable sources to either lack evidence or actively ignore evidence, such as claims that Pope John Paul I was murdered, or that the Apollo Moon landings were faked.
Some adherents of a religion might object to a critical historical treatment of their own faith because in their view such analysis discriminates against their religious beliefs.
Wikipedia articles about religious topics should take care to use these words only in their formal senses to avoid causing unnecessary offence or misleading the reader.
Conversely, editors should not avoid using terminology that has been established by the majority of the current reliable and relevant sources on a topic out of sympathy for a particular point of view or concern that readers may confuse the formal and informal meanings.
This type of split is permissible only if written from a neutral point of view and must not be an attempt to evade the consensus process at another article.
For example, the widely used names "Boston Massacre", "Teapot Dome scandal", and "Jack the Ripper" are legitimate ways of referring to the subjects in question despite appearing to pass judgment.
Try not to quote directly from participants engaged in a heated dispute; instead, summarize and present the arguments in an impartial, formal tone.
For instance, the article on Shakespeare should note that he is widely considered one of the greatest authors in the English language by both scholars and the general public.
Avoid the temptation to rephrase biased or opinion statements with weasel words, for example, "Many people think John Doe is the best baseball player."
Jimmy Wales has qualified NPOV as "non-negotiable", consistently, throughout various discussions: 2001 statement, November 2003, April 2006, March 2008.
