Wikipedia:No original research

Original research is a term used in Wikipedia to refer to material that has not been published by a reliable source. It includes unpublished facts, arguments, concepts, statements, or theories, or any unpublished analysis or synthesis of published material that appears to advance a position — or which, in the words of Wikipedia's co-founder Jimbo Wales, would amount to a "novel narrative or historical interpretation."

Wikipedia is not the place for original research. Citing sources and avoiding original research are inextricably linked: the only way to demonstrate that you are not doing original research is to cite reliable sources that provide information directly related to the topic of the article, and to adhere to what those sources say.

Wikipedia:No original research is one of three content policies. The other two are Wikipedia:Neutral point of view and Wikipedia:Verifiability. Jointly, these policies determine the type and quality of material that is acceptable in the main namespace. Because the three policies are complementary, they should not be interpreted in isolation from one another, and editors should try to familiarize themselves with all three. The principles upon which these three policies are based are non-negotiable on the English Wikipedia and cannot be superseded by other policies or guidelines, or by editors' consensus.

What is excluded?

The original motivation for the no original research policy was to combat people with personal theories, such as cranks and trolls, who would attempt to use Wikipedia to draw attention to their ideas and to themselves.

However, original research is more than just no personal crank theories. It also excludes editors' personal views, political opinions, their personal analysis or interpretation of published material, as well as any unpublished synthesis of published material, where such a synthesis appears to advance a position or opinion an editor may hold, or to support an argument or definition s/he may be trying to propose. That is, any facts, opinions, interpretations, definitions, and arguments published by Wikipedia must already have been published by a reliable publication in relation to the topic of the article. See this example for more details.

An edit counts as original research if it proposes ideas or arguments. That is, if it does any of the following:

• It introduces a theory or method of solution;
• It introduces original ideas;
• It defines new terms;
• It provides or presumes new definitions of pre-existing terms;
• It introduces an argument, without citing a reputable source for that argument, that purports to refute or support another idea, theory, argument, or position;
• It introduces an analysis or synthesis of established facts, ideas, opinions, or arguments in a way that builds a particular case favored by the editor, without attributing that analysis or synthesis to a reputable source;
• It introduces or uses neologisms, without attributing the neologism to a reputable source.

Primary, secondary, and tertiary sources

• Primary sources are documents or people very close to the situation you are writing about. An eyewitness account of a traffic accident is a primary source. The White House's summary of a president's speech is a primary source. Primary sources that have been published by a reliable source may be used in Wikipedia, but only with care, because it's easy to misuse them. For that reason, edits that rely on primary sources should only make descriptive claims that can be checked by anyone without specialist knowledge. Any interpretation of primary source material requires a secondary source.

Examples of primary sources include archeological artifacts; photographs; historical documents such as a diary, census, video or transcript of surveillance, a public hearing, trial, or interviews; tabulated results of surveys or questionnaires; written or recorded records of laboratory assays or observations; written or recorded records of field observations; and artistic and fictional works such as poems, scripts, screenplays, novels, motion pictures, videos, and television programs.

• Secondary sources are documents or people that summarize other material, usually primary source material. They are academics, journalists, and other researchers, and the papers and books they produce. A journalist's account of a traffic accident is a secondary source. A New York Times account of a president's speech is a secondary source. Wikipedia articles should rely on reliable, published secondary sources wherever possible. This means that we publish the opinions of reliable authors, and not the opinions of Wikipedians who have read the primary source material for themselves.

• Tertiary sources are publications, such as encyclopedias, that sum up other secondary sources, and sometimes primary sources. Wikipedia is a tertiary source.

Although most articles should rely predominantly on secondary sources, there are rare occasions when they may rely entirely on primary sources (for example, current events or Braunfeld v. Brown). An article or section of an article that relies on primary source should (1) only make descriptive claims the accuracy of which is easily verifiable by any reasonable adult without specialist knowledge, and (2) make no analytic, synthetic, interpretive, explanatory, or evaluative claims. Contributors drawing on entirely primary sources should be careful to comply with both conditions.

Wikipedia articles include material on the basis of verifiability, not truth. That is, we report what other reliable sources have published, whether or not we regard the material as accurate. In order to avoid doing original research, and in order to help improve the quality of Wikipedia articles, it is essential that any primary-source material, as well as any generalization, analysis, synthesis, interpretation, or evaluation of information or data, has been published by a reputable third-party publication (that is, not self-published) that is available to readers either from a website (other than Wikipedia) or through a public library.

Synthesis of published material serving to advance a position

Editors often make the mistake of thinking that if A is published by a reliable source, and B is published by a reliable source, then A and B can be joined together in an article in order to advance position C. However, this would be an example of a new synthesis of published material serving to advance a position, and as such it would constitute original research. "A and B, therefore C" is acceptable only if a reliable source has published this argument in relation to the topic of the article.

Here is an example from a Wikipedia article, with the names changed. The article was about Jones:

Smith says that Jones committed plagiarism by copying references from another book. Jones denies this, and says it's acceptable scholarly practise to use other people's books to find new references.

Now comes the unpublished synthesis of published material:

If Jones's claim that he consulted the original sources is false, this would be contrary to the practice recommended in the Chicago Manual of Style, which requires citation of the source actually consulted. The Chicago Manual of Style does not call violating this rule "plagiarism." Instead, plagiarism is defined as using a source's information, ideas, words, or structure without citing them.

This entire paragraph is original research, because it expresses the editor's opinion that, given the Chicago Manual of Style's definition of plagiarism, Jones did not commit it. To make the paragraph consistent with this policy, a reliable source is needed that specifically comments on the Smith and Jones dispute and makes the same point about the Chicago Manual of Style and plagiarism. In other words, that precise analysis must have been published by a reliable source in relation to the topic before it can be published in Wikipedia.

Citing oneself

"No original research" does not prohibit experts on a specific topic from adding their knowledge to Wikipedia. It does, however, prohibit expert editors from drawing on their personal and direct knowledge if such knowledge is unverifiable. Wikipedia welcomes the contributions of experts, as long as these contributions come from verifiable (i.e. published) sources. Thus, if an editor has published the results of his or her research elsewhere, in a reputable publication, then the editor may cite that source while writing in the third person and complying with our NPOV policy. We further hope expert editors will draw on their knowledge of other published sources to enrich our articles. While specialists do not occupy a privileged position within Wikipedia, they are often familiar with and have access to a wider range of verifiable sources and can thus be of special assistance in verifying or citing sources. See also Wikipedia's guidelines on conflict of interest.

Reliable publications

Reliable publications include peer-reviewed journals, books published by a known academic publishing house or university press, and divisions of a general publisher with a good reputation for scholarly publications.

For non-academic subjects, there is no firm definition of "reliable." In general, most of us have a good intuition about the meaning of the word. A magazine or press release self-published by an extremist political or religious group would not be regarded as "reliable," and could only be used in articles about those groups. In contrast, The New York Times is generally accepted as a trustworthy source.

Ask yourself some questions when you are evaluating a publication. Is it openly partisan? Does it have a large or very small readership? Is it a vanity publisher? Is it run principally by a single person, or does it have a large, permanent staff? Does it seem to have any system of peer review, or do you get the feeling that it shoots from the hip? If you heard that the publication you are about to use as a source was considering publishing a negative article about you, would you (a) be terrified because you suspect they are irresponsible and do not fact-check; or (b) feel somewhat reassured because the publication employs several layers of editing staff, fact-checkers, lawyers, an editor-in-chief, and a publisher, and will usually correct its mistakes? If it is (a), do not use it as a source. If it is (b), it is what Wikipedia calls "reliable."

Original images

Pictures have enjoyed a broad exception from this policy, in that Wikipedia editors are encouraged to take photographs or draw pictures and upload them, releasing them under the GFDL or another free license, to illustrate articles. This is welcomed because images generally do not propose unpublished ideas or arguments, the core reason behind the NOR policy. Also, because of copyright law in a number of countries and its relationship to the work of building a free encyclopedia, there are relatively few publicly available images we can take and use. Wikipedia editors' pictures fill a needed role.

A disadvantage of allowing original photographs to be uploaded is the possibility of editors using photo manipulation to distort the facts or position being illustrated by the photo. Manipulated images should be prominently noted as such and, if they are not, should be posted to Wikipedia:Images for deletion. Images that constitute original research in any other way are not allowed, such as a diagram of a hydrogen atom showing extra particles in the nucleus as theorized by the uploader.

Related policies and guidelines

Wikipedia:Verifiability

By insisting that only facts, assertions, theories, ideas, claims, opinions, and arguments that have already been published by a reputable publisher may be published in Wikipedia, the no-original-research and verifiability policies reinforce one another.

The threshold for inclusion in Wikipedia is verifiability, not truth.

See Wikipedia:Verifiability for more detailed information, and Wikipedia:Cite sources for examples of citation styles.

Wikipedia:Neutral point of view

The prohibition against original research limits the possibility of an editor presenting his or her own point of view in an article. Moreover, by reinforcing the importance of including verifiable research produced by others, this policy promotes the inclusion of multiple points of view in an article. Consequently, this policy reinforces our neutral point of view policy.

In many cases, there are multiple established views of any given topic. In such cases, no single position, no matter how well researched, is authoritative. It is not the responsibility of any one editor to research all points of view. But when incorporating research into an article, it is important that editors situate the research; that is, provide contextual information about the point of view, indicating how prevalent the position is, and whether it is held by a majority or minority.

How to determine whether a view is established

The inclusion of a view that is held only by a tiny minority may constitute original research because there may be a lack of sufficiently credible, third-party, published sources to back it up.

From a mailing list post by Jimbo Wales, Wikipedia's founder:

• If a viewpoint is in the majority, then it should be easy to substantiate it with reference to commonly accepted reference texts;
• If a viewpoint is held by a significant minority, then it should be easy to name prominent adherents;
• If a viewpoint is held by an extremely small (or vastly limited) minority, it doesn't belong in Wikipedia (except perhaps in some ancillary article) regardless of whether it's true or not; and regardless of whether you can prove it or not.

See Wikipedia:Neutral point of view for more detailed information.

Policy origin: the opinion of Wikipedia's founder

Wikipedia's founder, Jimbo Wales, has described the origin of the original research policy as follows:

The phrase "original research" originated primarily as a practical means to deal with physics cranks, of which of course there are a number on the Web. The basic concept is as follows: It can be quite difficult for us to make any valid judgment as to whether a particular thing is true or not. It isn't appropriate for us to try to determine whether someone's novel theory of physics is valid; we aren't really equipped to do that. But what we can do is check whether or not it actually has been published in reputable journals or by reputable publishers. So it's quite convenient to avoid judging the credibility of things by simply sticking to things that have been judged credible by people much better equipped to decide. The exact same principle will hold true for history." [1]

Some who completely understand why Wikipedia ought not create novel theories of physics by citing the results of experiments and so on and synthesizing them into something new, may fail to see how the same thing applies to history. [2]

On talk pages and project pages

Like most Wikipedia policies, No original research applies to articles, not to talk pages or project pages, although it is regarded as poor taste to discuss personal theories on talk pages.

A few pages have been created devoted to research into issues related to Wikipedia; for instance Wikipedia:Statistics Department and Wikipedia:WikiProject Wikidemia. These pages may contain original research; that is, research for which there is no reference other than projects in the Wikipedia namespace. Original research that does not have Wikipedia as its object should, however, be avoided on these pages too.

Other options

• Meta-Wiki allows original research, see for instance m:research, m:Wikiresearch, m:Wikimedia Research Network, m:wikiversity, m:category:research, and m:statistics.
• Wikipedia-style websites that allow original research but are not affiliated with the Wikimedia Foundation include Wikinfo, Everything 2 and Urban Dictionary.
• Wikinews allows original reporting. See the Original Reporting page on Wikinews for more information.
