This page is currently inactive and is retained for historical reference.
Either the page is no longer relevant or consensus on its purpose has become unclear. To revive discussion, seek broader input via a forum such as the village pump.

Wikipedia:Attribution was created to serve as a combination of Wikipedia:Verifiability, Wikipedia:No original research and Wikipedia:Reliable sources. A poll was held to ask for community input, and a bipartisan working party is currently being formed to develop a compromise proposal. See discussion.

This page documents an English Wikipedia policy.

It describes a widely accepted standard that all editors should normally follow. Changes made to it should reflect consensus.

This page in a nutshell:

Wikipedia is not a publisher of original thought.
Articles should only contain verifiable content from reliable sources without further analysis.
Content should not be synthesized to advance a position.

Original research (OR) is a term used in Wikipedia to refer to unpublished facts, arguments, concepts, statements, or theories. The term also applies to any unpublished analysis or synthesis of published material that appears to advance a position — or, in the words of Wikipedia's co-founder Jimmy Wales, would amount to a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 presenting 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 (NOR) is one of three content policies. The others are Wikipedia:Neutral point of view (NPOV) and Wikipedia:Verifiability (V). Jointly, these policies determine the type and quality of material that is acceptable in articles. Since the policies complement each other, they should not be interpreted in isolation from one another, and editors should try to familiarize themselves with all three.

What is excluded?

The original motivation for the "No original research" policy was to prevent people with personal theories attempting to use Wikipedia to draw attention to their ideas.^[1] Original research includes editors' personal views, political opinions, and any unpublished analysis or synthesis of published material that appears to advance a position. 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 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.

Sources

Reliable sources

Any material that is challenged or likely to be challenged must be accompanied by a reliable source. Material that counts as "original research" within the meaning of this policy is material for which no reliable source can be found and which is therefore believed to be the original thought of the Wikipedian who added it. The only way to show that your work is not original research is to produce a reliable published source who writes about the same claims or advances the same argument as you.

There is no firm definition of "reliable," although most of us have a good intuition about the meaning of the word. In general, the most reliable sources are books and journals published by university presses; mainstream newspapers; and magazines and journals published by known publishing houses. As a rule of thumb, the more people engaged in checking facts, analysing legal issues, and scrutinizing the writing, the more reliable the publication. Material that is self-published, whether on paper or online, is generally not regarded as reliable, but see Wikipedia:Verifiability for exceptions.

Primary, secondary, and tertiary sources

Primary sources are documents or people very close to the situation being written about. An eyewitness account of a traffic accident is a primary source. United Nations Security Council resolutions are primary sources. 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, anyone—without specialist knowledge—who reads the primary source should be able to verify that the Wikipedia passage agrees with the primary source. Any interpretation of primary source material requires a secondary source.
Examples of primary sources include archeological artifacts; photographs; newspaper accounts which contain first-hand material, rather than analysis or commentary of other material; historical documents such as diaries, census results, video or transcripts of surveillance, public hearings, trials, or interviews; tabulated results of surveys or questionnaires; written or recorded notes of laboratory and field experiments or observations; and artistic and fictional works such as poems, scripts, screenplays, novels, motion pictures, videos, and television programs.

Secondary sources draw on primary sources to make generalizations or original interpretive, analytical, synthetic, or explanatory claims. A journalist's analysis or commentary of a traffic accident based on eye-witness reports is a secondary source. An International Herald Tribune analysis and commentary on a United Nations Security Council resolution is a secondary source. An historian's interpretation of the decline of the Roman Empire, or analysis of the historical Jesus, constitute secondary sources. Wikipedia articles should rely on reliable, verifiable, published secondary sources. This means that we present verifiable accounts of views and arguments of reliable scholars, and not interpretations of primary source material by Wikipedians.

Tertiary sources are publications, such as encyclopedias, that sum up other secondary sources, and sometimes primary sources. (Wikipedia itself is a tertiary source.) Some tertiary sources are more reliable than others, and within any given tertiary source, some articles may be more reliable than others. For example, articles signed by experts in Encyclopaedia Britannica and encyclopedias of similar quality can be regarded as reliable secondary sources instead of tertiary ones. Unsigned articles may be less reliable, but they may be used so long as the encyclopedia is a high quality one.

Original research that creates primary sources is not allowed. However, research that consists of collecting and organizing information from existing primary and/or secondary sources is, of course, strongly encouraged. All articles on Wikipedia should be based on information collected from published primary and secondary sources. This is not "original research"; it is "source-based research", and it is fundamental to writing an encyclopedia.

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 legal cases). An article or section of an article that relies on a primary source should (1) only make descriptive claims, the accuracy of which is easily verifiable by any reasonable, educated person 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.

WP:SYN

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 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.^[2] "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 practice to use other people's books to find new references.

That much is fine. 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

This policy does not prohibit editors with specialist knowledge from adding their knowledge to Wikipedia, but it does prohibit them from drawing on their personal knowledge without citing their sources. If an editor has published the results of his or her research in a reliable publication, then s/he may cite that source while writing in the third person and complying with our NPOV policy. See also Wikipedia's guidelines on conflict of interest.

Original images

Pictures have enjoyed a broad exception from this policy, in that Wikipedia editors are encouraged to take photographs or draw pictures or diagrams 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. If they are noted as manipulated, they should be posted to Wikipedia:Images for deletion if the manipulation materially affects the encyclopedic value of the image. 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.

Verifiability (V)

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

Neutral point of view (NPOV)

The prohibition against original research limits the possibility of an editor presenting his or her own point of view in an article. 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 NPOV 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.

The inclusion of a view that is held only by a tiny minority may constitute original research. Jimbo Wales, Wikipedia's co-founder, has said of this:

If your viewpoint is in the majority, then it should be easy to substantiate it with reference to commonly accepted reference texts;
If your viewpoint is held by a significant minority, then it should be easy to name prominent adherents;
"If your viewpoint is held by an extremely small minority, then — whether it's true or not, whether you can prove it or not — it doesn't belong in Wikipedia, except perhaps in some ancillary article. Wikipedia is not the place for original research." ^[3]

Is original research ever permissible?

Original research should not be included in new articles or additions to existing Wikpedia articles. However:

1. This does not apply to talk pages or to any other page that is not a Wikipedia article (including, but not limited to, the village pump, mediation pages, and user pages.) When editors suggest an addition to an article, they should endeavor to find sources for their claims but sources are not required to discuss an issue. On the contrary, synthesis is often a vital part of the decision making process even though it isn't allowed in the article itself.

In other words, original research may be used as an argument for the inclusion of reputably sourced material, but the fruits of that research must not be included in the article itself.

2. This does not apply to the proposed removal or alteration of unsourced material from the article.

3. This does not apply to proposed formatting, rewording (so long as the reworded version does not contradict any applicable sources), page redirection, or any other sort of action that does not add new content to the article or remove/alter content that is properly sourced.

4. If doubt exists over whether something is original research, consider the overall necessity to the article. If there is a consensus that article suffers significantly without it, put it in (see WP:IAR.)

These exceptions exist to facilitate intelligent debate, not shoehorn your own personal opinion into an article. Original research does not imply bias--editors are still expected to present a neutral point of view.

Other options

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.
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.

Notes

^ Wikipedia's co-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." (Wales, Jimmy. "Original research", December 3, 2004)
^ Mr. Wales disapproves of synthesized historical theories and states: "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." (Wales, Jimmy. "Original research", December 6, 2004)
