NPOV is an acronym for Neutral Point of View, which is an official policy of Wikipedia.

Everybody has a point of view. Though 99% of the world may see something exactly the way you do, still your view is just one of many possible views that might be reasonably held. For example, what does it mean to be liberal? Some have said that this political stance means that the government should actively intervene to ensure fairness, while others have stated the opposite, that liberals seek to maximize individual opportunity and minimize government. Can a sensible article on Liberalism acknowledge such beliefs? Yes, and this tutorial will tell you how.

First: Negotiating neutrality with others

The first element in negotiating issues of bias with others is to recognize you have a point of view, and to pin-point where it comes from. "It's what everybody I know believes," is a start. But in co-writing an article with someone who believes differently, it's often important to have some evidence at hand. This includes not only evidence for your view but evidence for how many others hold it and who they are. Information like this enables writers and participants in discussion to come to practical decisions. These include whether one view deserves to go first, whether two deserve equal billing, whether views belong in different articles and, if so, what titles the articles should have.

Word ownership

A common source of obstinacy in NPOV disputes is the belief that one group "owns" a word and has sole authority to define it:

"The word liberalism was coined by political philosophers. Political philosophers are the experts on liberalism, and not one of them alive today believes that liberalism is the same thing as libertarianism."

In fact, many words have multiple meanings, and it's not just that one person sometimes uses "liberal" to refer to a political movement and sometimes to refer to generous use of an ingredient in a recipe. Sometimes it means that different people mean different things when they say the same word.

The fact that a right-wing Russian nationalist party is called the Liberal Democratic Party of Russia isn't covered by any senses of the word provided in the dictionary. Neither are the views of the original Liberals, who opposed the clergy and mercantilism. But in an encyclopedia, ideas that a lot of people believe or once believed deserve not only mention but respectful treatment. Many of these problems can be solved through what we call disambiguation.

At the same time, the fact that you disagree with the way a word is used or defined does not automatically imply that there is a POV problem. You must also ensure that your assertions about alternative uses are both significant and verifiable, using appropriate attribution and citation.

Attribution and citation

An attribution specifies who stands behind a claim. In this example:

"According to [Rock and Roll Survey 1998]" most Australians think The Beatles are the best rock music group ever.

the sentence attributes to "[Rock and Roll Survey 1998]" the claim that most Australians think the Beatles are the best group ever.

A citation tells readers where they can look to verify that the attribution is accurate. The underlined section above also leads to the citation.

Make only careful use of generic attributions ("Critics say..."). These are called weasel words, because they can make claims look less obscure or less controversial than they are. In general, when something needs attributing, be specific.

See: Wikipedia:Cite sources, Wikipedia:Verifiability.

Neutral language

Assertions written in neutral language are closer to being objectively true. One such neutral assertion is this:

"In 1989, Drs. Stanley Pons and Martin Fleischmann of the University of Utah shocked the world by reporting they had discovered a means to tap energy from nuclear fusion at near to room temperatures."

Even though very few scientists believe Pons' and Fleischmann's report was accurate, let alone responsible, probably none would disagree with the assertion made in the previous sentence. However, "[...] shocked the world [...]" is probably more dramatic, and less accurate, than had the statement been "[...] shocked the scientific community [...]". This serves as an example of the difficulty of finding truly objective wording.

As a political example, take the status of Jerusalem. The government of Israel considers it to be that nation's capital, but many other governments do not, and have gone so far as to place their embassies elsewhere. Disagreement about what city is the capital of Israel caused heated arguments on Wikipedia. But the facts as stated above were ones that all could agree on. The solution? Stick to the facts.

When a fact is not common knowledge, or when the information being related is a subjective assessment, like the result of a particular poll, the information should be attributed and cited.

Accusations

Attribution and citation are especially important for claims against a person ("Michael Jackson is a child abuser"). Note that many accusations are neither wholly true nor entirely baseless. Accusers often have evidence for a real offense, but choose hyperbolic words in naming it. A good way to handle such a situation might be like this:

"The boy's mother accused Jackson of sharing his bed with the boy, and called this 'child abuse'."

In other words, simply sharing a bed with a strange child is not what the words "child abuse" convey to most people, even if many might agree that to do so is improper. But if "child abuse" hits the airwaves and becomes news, it should not be omitted. The solution, as with other controversial claims, is to put it in quotes.

Obviously, false accusations are unfair and non-neutral, so if you suspect or know an accusation to be insincere, attempt to "neutralize" it. Unfortunately, without a confession from the accuser, insincerity is hard to prove. The best way to proceed in these cases is to locate reliable sources that treat this issue and attribute the discussion to them. Be sure to cover all sides of any debate in order to ensure the article remains neutral. Give the facts to the reader to decide for themselves.

"The boy's mother accused Jackson of sharing his bed with the boy, and called this 'child abuse'. While Joe Blow of the Foo Daily News suggested a financial motive for the accusation, the mother's lawyer has denied this claim."

That's about the best you can do. It is not neutral to say: "Of course, she's probably lying."

Insinuation

While hinting or insinuating may feel weak, it is a powerful tool and abuse of it is a common way of introducing bias. Consider the example:

The minister of parliament has been accused of lacking backbone and of being unwilling to use the armed forces to defend our rights. He acknowledged last month that he is left-handed.

To mention the minister's left-handedness in this context is to imply that it is relevant. As a result, this juxtaposition of otherwise neutral statements has the effect of fostering prejudice, in particular the prejudice that all left-handers are wimps. Insinuations of this sort are guaranteed to prompt complaints. Do not use or tolerate them.

Bias in attribution: Mind your nuances

It's possible to introduce your own bias even while attributing. Take this sentence as an example:

"Duane Gish said that the Earth and its living creatures were created by God."

This is a neutral statement as it stands. But what if "said" were substituted with:

Noted
Explained
Pointed out
Claimed
Suggested

All have different connotations, which could introduce bias, depending on context. "Noted", "pointed out", and "explained" in particular, imply that the Earth indeed was created by God, which many people consider false. In choosing words, imagine how a sentence will read to someone with another POV, and choose carefully. Whenever "said", "wrote", or "stated" are options, they are usually the safest.

For more on terms to watch out for, see Wikipedia:Words to avoid.

Space and balance

An article can be written in neutral language and yet omit important points of view. Such an article should be considered an NPOV work in progress, not an irredeemable piece of propaganda. Often an author presents one POV because it's the only one that he or she knows well. The remedy is to add to the article — not to subtract from it.

Different views don't all deserve equal space. Articles need to be interesting to attract and keep the attention of readers. For an entry in an encyclopedia, ideas also need to be important. The amount of space they deserve depends on their importance and how many interesting things can be said about them.

Information suppression

A common way of introducing bias is by one-sided selection of information. Information can be cited that supports one view while some important information that opposes it is omitted or even deleted. In this manner, the full range of views on a subject can be unfairly presented or concealed whilst still complying with Wikipedia:Verifiability. Remember that Verifiability is just one of Wikipedia's three content-guiding policy pages. The other two are NPOV and No original research. All three are necessary for an article to be considered compliant.

Some examples of how editors may unwittingly or deliberately present a subject in an unfair way:

Biased or selective representation of sources, eg:
- Explaining why evidence supports one view, but omitting such explanation in support of alternative views.
- Making one opinion look superior by omitting strong and citable points against it, comparing it instead with low quality arguments for other POV's (strawman tactics).
- Not allowing one view to "speak for itself", or refactoring its "world-view" into the words of its detractors.
Editing as if one given opinion is "right" and therefore other opinions have little substance:
- Entirely omitting significant citable information in support of a minority view, with the argument that it is claimed to be not credible.
- Ignoring or deleting significant views, research or information from notable sources that would usually be considered credible and verifiable in Wikipedia terms (this could be done on spurious grounds).
- Concealing relevant information about sources or sources' credentials that is needed to fairly judge their value.

Thus, verifiability, proper citation and neutral phrasing are necessary but not sufficient to ensure NPOV. It is important that the various views and the subject as a whole are presented in a balanced manner and that each is summarized as if by its proponents to their best ability.

Expertise

On many scientific, technical or social problems, different points of view may be held by different experts. This is especially the case, for instance, in areas of conjecture (e.g. estimating the future importance of global warming). Wikipedia should report all major points of views; however, it should do so in proportion to the credibility of the experts holding the various theses.

One measure of a view's importance is the credibility of the experts who hold that view. What makes an expert credible? Some criteria include:

The reputation of the expert, the reputation of the tradition within which he or she works, the reputation of the group or institution for which the expert works
Whether the expert uses the common methods of the field or completely different ones
Whether the expert has or has not failed to respond to criticisms
Whether the expert has reputable supporters of his or her claims
Whether the expert's point of view belongs in a different article (e.g. evolution vs. creationism)

In other words, an idea's popularity alone does not determine its importance. Few people may know that a belief is wrong, but sometimes that is because most are unaware of the evidence against it. If you are not an expert in a subject yourself, your intuition that an article is biased may not be reliable. Keep an open mind and ask others about the evidence.

Points of view held as having little credibility by experts, but with wide popular appeal (e.g.: the belief in astrology, considered as irrational and incorrect by the vast majority of scientists and astronomers), should be reported, but as such: that is, we should expose the point of view and its popular appeal, but also the opinion held by the vast majority of experts.

Moral and political points of view

On certain topics, there is naturally less "expertise" and scientific thinking, and more "opinion". This is especially the case of topics such as morals or religion, based on faith, as well as politics.

We should then list all points of views, according to their importance, and, if possible, be precise as to who holds them. There exist some cases where the vast majority of political parties, politicians and journalists hold a certain opinion, while a sizeable minority do not: both views should be stated.

One common problem with politics is the natural tendency of considering the major political opinions of one's country as "normal", while considering those held in other countries as "abnormal", silly, or misguided. Thus, for instance, an article written from an American point of view may judge that the European fondness for welfare state solutions is misguided, or express this point of view in oblique ways; the same could be true of an article written from a European point of view on justice and firearms in the United States. Writers should thus combat this natural tendency of considering the point of view of one's groups as the "majority" and "natural" point of view, and giving to it more space and more focus.

Article splitting

When an article becomes too long (see wikipedia:article size), a split is recommended. Such split can be performed in a POV way, for example putting everything you don't like in a new article, give that article an un- common name, so obfuscating its whereabouts. The NPOV way of splitting articles is explained in Wikipedia:Content forking: every main section of the article is reduced in size, keeping to the "space and balance" principle as explained above, and an equal number of sub-pages is created using a technique as explained in wikipedia:summary style.

The most important lesson

More important than being able to write neutrally without thinking about it is being willing and knowing how to work with others toward that goal. Be bold in editing pages that are biased, be bold in asking for help, and do not be alarmed when others edit your articles.

Realize you may have a bias you're not aware of, that you might have learned something wrong or that you might be misremembering it. Consider that even when an article has struck everyone who has read it so far as neutral, others arriving with a different bias may still have a good reason to change it. Often even a neutral article can be made still more neutral.

Regard bias as a problem with the article, not with the people who wrote it. Compromise, don't attack. For users you can't reason with and who seem determined to violate NPOV policy, enlist the help of the Wikipedia mediators. Just never forget to give discussion an honest try. Once they are given a little courtesy and respect, you might be surprised how many Wikipedians turn out to be not so biased after all.

Things to avoid

Some Wikipedians, in the name of neutrality, try to avoid making any statements that other people find offensive or objectionable, even if objectively true. This is not the intent of striving for neutrality. Many groups would prefer that certain facts be stated euphemistically, or only in their own terminology, or suppressed outright; such desires need not be deferred to. On the other hand, these terms should be presented, explained and examples given, perhaps with views of other groups of why the term is used as well as the group itself.

Article names

For an article name it is not usually possible to include all views on the article name in the article title itself, for example there is:

Alfred the Great

There is no way of making that more NPOV by naming the article:

Alfred the Great according to most people, but not according to some

The essential guidelines for making article names the most NPOV possible are included in:

Categorisation

Also for categorisation NPOV cannot always be achieved by adding more categories to the bottom of the article, while that would end up making the list of categories at the bottom of an article nearly as long as the body of the article itself.

The key recommendation for addressing such POV/NPOV issues comes from Wikipedia:Categorization of people (while indeed, people articles appear to be the most sensitive to POV/NPOV categorisation disputes):

[for sensitive categories:] Try to limit the number of categories to what is most essential about this person, something in the vein of: "give me 4 or 5 words that best characterize this person."

So, as an example, there is no doubt a "significant minority" would consider Menachem Begin a state terrorist - while, however one turns it, this is not one of the 4 or 5 essential characteristics of this person, a "state terrorists" category will not be found at the bottom of the article of this person.

Handling NPOV disputes

Handling NPOV disputes has no separate ruleset from what is described in Wikipedia:Dispute resolution

Template messages that might come in handy when dealing with such issues are most of them listed at Wikipedia:Template messages/Disputes.

Other standard templates that may help in addressing NPOV-related issues regarding articles can, for example, be found in Wikipedia:Template messages/Cleanup. For categories all available standard templates are listed at Wikipedia:Template messages/Category namespace

Note that the templates that can be used for NPOV concerns generally suppose that the suspected NPOV problem is explained on the article's or category's talk page. When all NPOV-related issues detailed on the talk page have been handled, the template should be removed from the article or category page. In most cases, however, the least cumbersome way of handling NPOV concerns would be to improve the article or the category description, so that it is no longer POV.
