|This page in a nutshell: Articles must not take sides, but should explain the sides, fairly and without editorial bias. This applies to both what you say and how you say it.|
All encyclopedic content on Wikipedia must be written from a neutral point of view (NPOV), which means representing fairly, proportionately, and, as far as possible, without editorial bias, all of the significant views that have been published by reliable sources on a topic.
NPOV is a fundamental principle of Wikipedia and of other Wikimedia projects. It is also one of Wikipedia's three core content policies; the other two are "Verifiability" and "No original research". These policies jointly determine the type and quality of material that is acceptable in Wikipedia articles, and, because they work in harmony, they should not be interpreted in isolation from one another. Editors are strongly encouraged to familiarize themselves with all three.
This policy is non-negotiable, and the principles upon which it is based cannot be superseded by other policies or guidelines, nor by editor consensus.
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. Wikipedia aims to describe disputes, but not engage in them. Editors, while naturally having their own points of view, should strive in good faith to provide complete information, and not to promote one particular point of view over another. As such, the neutral point of view does not mean exclusion of certain points of view, but including all verifiable points of view which have sufficient due weight. Observe the following principles to achieve the level of neutrality that is appropriate for an encyclopedia:
As a general rule, do not remove sourced information from the encyclopedia solely on the grounds that it seems biased. Instead, try to rewrite the passage or section to achieve a more neutral tone. 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 only where you have a good reason to believe it misinforms or misleads readers in ways that cannot be addressed by rewriting the passage. The sections below offer specific guidance on common problems.
In some cases, the choice of name used for a topic can give an appearance of bias. While neutral terms are generally preferable, this must be balanced against clarity. If a name is widely used in reliable sources (particularly those written in English), and is therefore likely to be well recognized by readers, it may be used even though some may regard it as biased. 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, even though they may appear to pass judgment. The best name to use for a topic may depend on the context in which it is mentioned; it may be appropriate to mention alternative names and the controversies over their use, particularly when the topic in question is the main topic being discussed.
This advice especially applies to article titles. Although multiple terms may be in common usage, a single name should be chosen as the article title, in line with the article titling policy (and relevant guidelines such as on geographical names). Article titles that combine alternative names are discouraged. For example, "Derry/Londonderry", "Aluminium/Aluminum" or "Flat Earth (Round Earth)" should not be used. Instead, alternative names should be given due prominence within the article itself, and redirects created as appropriate.
Some article titles are descriptive, rather than being a name. Descriptive titles should be worded neutrally, so as not to suggest a viewpoint for or against a topic, or to confine the content of the article to views on a particular side of an issue (for example, an article titled "Criticisms of X" might be better renamed "Societal views on X"). Neutral titles encourage multiple viewpoints and responsible article writing.
The internal structure of an article may require additional attention, to protect neutrality, and to avoid problems like POV forking and undue weight. Although specific article structures are not, as a rule, prohibited, care must be taken to ensure that the overall presentation is broadly neutral.
Segregation of text or other content into different regions or subsections, based solely on the apparent POV of the content itself, may result in an unencyclopedic structure, such as a back-and-forth dialogue between proponents and opponents. 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. Try to achieve a more neutral text by folding debates into the narrative, rather than isolating them into sections that ignore or fight against each other.
Pay attention to headers, footnotes, or other formatting elements that might unduly favor one point of view, and 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.
Neutrality requires that each article or other page in the mainspace fairly represent all significant viewpoints that have been published by reliable sources, in proportion to the prominence of each viewpoint in the published, reliable sources. Giving due weight and avoiding giving undue weight means that articles should not give minority views or aspects as much of or as detailed a description as more widely held views or widely supported aspects. Generally, the views of tiny minorities should not be included at all, except perhaps in a "see also" to an article about those specific views. For example, the article on the Earth does not directly mention modern support for the flat Earth concept, the view of a distinct minority; to do so would give undue weight to it.
Undue weight can be given in several ways, including but not limited to depth of detail, quantity of text, prominence of placement, and juxtaposition of statements. In articles specifically relating to a minority viewpoint, such views may receive more attention and space. However, these pages should still make appropriate reference to the majority viewpoint wherever relevant and must not represent content strictly from the perspective of the minority view. Specifically, it should always be clear which parts of the text describe the minority view. In addition, the majority view should be explained in sufficient detail that the reader can understand how the minority view differs from it, and controversies regarding aspects of the minority view should be clearly identified and explained. How much detail is required depends on the subject. For instance, articles on historical views such as Flat Earth, with few or no modern proponents, may briefly state the modern position, and then go on to discuss the history of the idea in great detail, neutrally presenting the history of a now-discredited belief. Other minority views may require much more extensive description of the majority view to avoid misleading the reader. See fringe theories guideline and the NPOV FAQ.
Wikipedia should not present a dispute as if a view held by a small minority deserves as much attention overall as the majority view. Views that are held by a tiny minority should not be represented except in articles devoted to those views (such as Flat Earth). To give undue weight to the view of a significant minority, or to include that of a tiny minority, might be misleading as to the shape of the dispute. Wikipedia aims to present competing views in proportion to their representation in reliable sources on the subject. This applies not only to article text, but to images, wikilinks, external links, categories, and all other material as well.
Keep in mind that, in determining proper weight, we consider a viewpoint's prevalence in reliable sources, not its prevalence among Wikipedia editors or the general public.
If you can prove a theory that few or none currently believe, Wikipedia is not the place to present such a proof. Once it has been presented and discussed in reliable sources, it may be appropriately included. See "No original research" and "Verifiability".
An article should not give undue weight to minor aspects of its subject, but should strive to treat each aspect with a weight proportional to its treatment in the body of reliable, published material on the subject. For example, discussion of isolated events, criticisms, or news reports about a subject may be verifiable and impartial, but still disproportionate to their overall significance to the article topic. This is a concern especially in relation to recent events that may be in the news.
While it is important to account for all significant viewpoints on any topic, Wikipedia policy does not state or imply that every minority view 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. Conspiracy theories, pseudoscience, speculative history, or plausible but currently unaccepted theories should not be legitimized through comparison to accepted academic scholarship. We do not take a stand on these issues as encyclopedia writers, for or against; we merely omit this information where including it would unduly legitimize it, and otherwise include and describe these ideas in their proper context with respect to established scholarship and the beliefs of the wider world.
Good and unbiased research, based upon the best and most reputable authoritative sources available, helps prevent NPOV disagreements. Try the library for reputable books and journal articles, and look online for the most reliable resources. 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.
Neutrality assigns weight to viewpoints in proportion to their prominence. However, when reputable sources contradict one another and are relatively equal in prominence, describe both points of view and work for balance. This involves describing the opposing views clearly, drawing on secondary or tertiary sources that describe the disagreement from a disinterested viewpoint.
Wikipedia describes disputes. Wikipedia does not engage in disputes. A neutral characterization of disputes requires presenting viewpoints with a consistently impartial tone; otherwise articles end up as partisan commentaries even while presenting all relevant points of view. Even where a topic is presented in terms of facts rather than opinions, inappropriate tone can be introduced through the way in which facts are selected, presented, or organized. Neutral articles are written with a tone that provides an unbiased, accurate, and proportionate representation of all positions included in the article.
The tone of Wikipedia articles should be impartial, neither endorsing nor rejecting a particular point of view. Try not to quote directly from participants engaged in a heated dispute; instead, summarize and present the arguments in an impartial tone.
Wikipedia articles about art and other creative topics (e.g., musicians, actors, books, etc.) have a tendency to become effusive. This is out of place in an encyclopedia. Aesthetic opinions are diverse and subjective--we might not all agree about who the world's greatest soprano is. However, it is appropriate to note how an artist or a work has been received by prominent experts and the general public. For instance, the article on Shakespeare should note that he is widely considered to be one of the greatest authors in the English language. Articles should provide an overview of the common interpretations of a creative work, preferably with citations to experts holding that interpretation. Verifiable public and scholarly critiques provide useful context for works of art.
There are no forbidden words or expressions on Wikipedia, but certain expressions should be used with care, because they may introduce bias. For example, the word claim, as in "Jim claimed he paid for the sandwich", could imply a lack of credibility. Using this or other expressions of doubt may make an article appear to promote one position over another. Try to state the facts more simply without using such loaded words; for example, "Jim said that he paid for the sandwich". Strive to eliminate expressions that are flattering, disparaging, vague, or clichéd, or that endorse a particular point of view (unless those expressions are part of a quote from a noteworthy source).
A common argument in a dispute about reliable sources is that one source is biased and so another source should be given preference. The bias in sources argument is one way to present a POV as neutral by excluding sources that dispute the POV as biased. Biased sources are not inherently disallowed based on bias alone, although other aspects of the source may make it invalid. Neutral point of view should be achieved by balancing the bias in sources based on the weight of the opinion in reliable sources and not by excluding sources that do not conform to the editor's point of view. This does not mean any biased source must be used; it may well serve an article better to exclude the material altogether.
Biased statements of opinion can be presented only with attribution. For instance, "John Doe is the best baseball player" expresses an opinion and cannot be asserted in Wikipedia as if it were a fact. It can be included as a factual statement about the opinion: "John Doe's baseball skills have been praised by baseball insiders such as Al Kaline and Joe Torre." Opinions must still be verifiable and appropriately cited.
Another approach is to specify or substantiate the statement, by giving those details that actually are factual. For example: "John Doe had the highest batting average in the major leagues from 2003 through 2006." People may still argue over whether he was the best baseball player. But they will not argue over this.
Avoid the temptation to rephrase biased or opinion statements with weasel words, for example, "Many people think John Doe is the best baseball player." But "Who?" and "How many?" are natural objections. An exception is a situation where a phrase such as "Most people think" can be supported by a reliable source, such as in the reporting of a survey of opinions within the group.
A POV fork is an attempt to evade the neutrality policy by creating a new article about a subject that is already treated in an article, often to avoid or highlight negative or positive viewpoints or facts. POV forks are not permitted in Wikipedia.
All facts and significant points of view on a given subject should be treated in one article except in the case of a spinoff sub-article. Some topics are so large that one article cannot reasonably cover all facets of the topic, so a spinoff sub-article is created. For example, Evolution as fact and theory is a sub-article of Evolution, and Creation-evolution controversy is a sub-article of Creationism. 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.
When writing articles, there may be cases where making some assumptions is necessary to get through a topic. For example, in writing about evolution, it is not helpful to hash out the creation-evolution controversy on every page. There are virtually no topics that could proceed without making some assumptions that someone would find controversial. This is true not only in evolutionary biology, but also in philosophy, history, physics, etc.
It is difficult to draw up a rule, but the following principle may help: there is probably not a good reason to discuss some assumption on a given page, if that assumption is best discussed in depth on some other page. However, a brief, unobtrusive pointer might be appropriate.
Wikipedia deals with numerous areas that are frequently subjects of intense debate both in the real world and among editors of the encyclopedia. A proper understanding and application of NPOV is sought in all areas of Wikipedia, but it is often needed most in these.
Pseudoscientific theories are presented by proponents as science, but characteristically fail to adhere to scientific standards and methods. Conversely, by its very nature, scientific consensus is the majority viewpoint of scientists towards a topic. Thus, when talking about pseudoscientific topics, we should not describe these two opposing viewpoints as being equal to each other. While pseudoscience may in some cases be significant to an article, it should not obfuscate the description of the mainstream views of the scientific community. Any inclusion of pseudoscientific views should not give them undue weight. The pseudoscientific view should be clearly described as such. An explanation of how scientists have reacted to pseudoscientific theories should be prominently included. This helps us to describe differing views fairly. This also applies to other fringe subjects, for instance, forms of historical revisionism 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 landing was faked.
See Wikipedia's established pseudoscience guidelines to help with deciding whether a topic is appropriately classified as pseudoscience.
In the case of beliefs and practices, Wikipedia content should not only encompass what motivates individuals who hold these beliefs and practices, but also account for how such beliefs and practices developed. Wikipedia articles on history and religion draw from a religion's sacred texts as well as from modern archaeological, historical, and scientific sources.
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. Their point of view must be mentioned if it can be documented by relevant, reliable sources, yet note that there is no contradiction. NPOV policy means that Wikipedia editors ought to try to write sentences like this: "Certain Frisbeetarianists (such as the Rev. Carlin) believe This and That, and also believe that This and That have been tenets of Frisbeetarianism from its earliest days; however, influenced by the findings of modern historians and archaeologists (such as Dr. Investigate's textual analysis and Prof. Iconoclast's carbon-dating work) certain sects -- calling themselves Ultimate Frisbeetarianists -- still believe This, but instead of That now believe Something Else."
Several words that have very specific meanings in studies of religion have different meanings in less formal contexts, e.g., fundamentalism, mythology, and (as in the prior paragraph) critical. 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. Details about particular terms can be found at Wikipedia:Manual of Style/Words to watch.
Common objections or concerns raised to Wikipedia's NPOV policy include the following.
Since the NPOV policy is often unfamiliar to newcomers--and is so central to Wikipedia's approach--many issues surrounding it have been covered before very extensively. If you have some new contribution to make to the debate, you could try the policy talk page. Before asking, please review the links below.
NPOV is one of the oldest policies on Wikipedia.
