This guideline discusses the reliability of various types of sources. The policy on sourcing is ], which requires ] for any material challenged or likely to be challenged, and for all quotations. The verifiability policy is strictly applied to all material in the mainspace—articles, lists, and sections of articles—without exception, and in particular to ], which states: | |||
'''If you can provide useful information to Misplaced Pages, please do so, but bear in mind that edits for which no reliable references are provided may be removed by any editor.''' | |||
{{quote|Contentious material about living persons (or, ]) that is unsourced or poorly sourced—whether the material is negative, positive, neutral, or just questionable—must be removed immediately and without waiting for discussion.}} | |||
What follows is a description of Misplaced Pages's best practices. Many articles may fall short of this standard until one or more editors devote time and effort to fact-checking and reference-running. (See ].) In the meantime, readers can still benefit from your contributions, bearing in mind that unsourced edits, or edits relying on inappropriate sources, may be challenged at any time. | |||
In the event of a contradiction between this guideline and our policies regarding sourcing and attribution, the policies take priority and editors should seek to resolve the discrepancy. Other policies relevant to sourcing are ] and ]. For questions about the reliability of particular sources, see ]. | |||
There are many ways in which factual errors can be introduced into reports. Keep in mind that many articles are about characterizing the various factions in a dispute. This means that you will be looking for reliable published reports of people's opinions. | |||

] | |||
Articles should be based on reliable, ], published sources with a reputation for fact-checking and accuracy. This means that we publish only the analysis, views, and opinions of reliable authors, and not those of Wikipedians, who have read and interpreted primary source material for themselves. The following examples cover only some of the possible types of reliable sources and source reliability issues, and are not intended to be exhaustive. Proper sourcing ''always'' depends on context; common sense and editorial judgment are an indispensable part of the process. | |||
===Definition of a source=== | |||
Please note the following terms: | |||
{{shortcut|WP:SOURCEDEF}} | |||
A ''source'' is where the material comes from. For example, a source could be a book or a webpage. A source can be reliable or unreliable for the material it is meant to support. Some sources, such as unpublished texts and an editor's own personal experience, are prohibited. | |||
When editors talk about sources that are being cited on Misplaced Pages, they might be referring to any one of these three concepts: | |||
* A ] is an ] state of affairs, which can be an historical event, or a social or natural phenomenon. To say of a ] or ] that it is ] is to say that it refers to a fact. | |||
* The piece of work itself (the article, book) | |||
* An ] is a view that someone holds, the content of which may or may not be verifiable. However, that a certain person or group holds a certain opinion ''is'' a fact, and it may be included in Misplaced Pages if it can be ]; that is, if you can cite a good source showing that the person or group holds the opinion. | |||
* The creator of the work (the writer, journalist) | |||
* A ] is a document or person providing direct evidence of a certain state of affairs; in other words, a source very close to the situation you are writing about. The term most often refers to a document produced by a participant in an event or an observer of that event. It could be an official report, an original letter, a media account by a journalist who actually observed the event, or an autobiography. Statistics compiled by an authoritative agency are considered primary sources. In general, Misplaced Pages articles should not depend on primary sources but rather on reliable secondary sources who have made careful use of the primary-source material. Most primary-source material requires training to use correctly, especially on historical topics. Misplaced Pages articles may use primary sources only if have been published by a reliable publisher e.g. trial transcripts published by a court stenographer, or historic documents that appear in edited collections. '''We may not use primary sources whose information has not been made available by a reliable publisher.''' See ] and ] | |||
* The publisher of the work (for example, ] or ]) | |||
* A ] summarizes one or more primary or secondary sources. Secondary sources produced by scholars and published by scholarly presses are carefully vetted for quality control and can be considered authoritative. A ] usually summarizes secondary sources. Misplaced Pages is a tertiary source. | |||
{{strong|Any of the three can affect reliability.}} Reliable sources may be published materials with a reliable publication process, authors who are regarded as authoritative in relation to the subject, or both. These qualifications should be demonstrable to other people. | |||
When reporting facts, Misplaced Pages articles should ]. There is a wealth of reliable information in tertiary sources such as the ]. Note that unsigned ''Encyclopedia Britannica'', ''World Book'' and ''Encarta'' articles are written by staff, not by experts, and do not have the same level of credibility. In recent years there has been a proliferation of specialized encyclopedias some in one volume and others multi-volume such as the ] and the ]. They can be considered authoritative. Older editions such as the ] often have fuller articles than current editions on some subjects, though there is always the danger that the information is outdated. | |||
===Definition of ''published''=== | |||
When reporting that an opinion is held by a particular individual or group, the best citation will be to a direct quote, citing the source of the quote in full after the sentence (see ]) or using a footnote or embedded link if the source is online. See ] for more details. If there is text, audio, or video available of someone expressing the opinion directly, you may include or transcribe an excerpt, which is allowed under ]. | |||
{{redirect-distinguish2|WP:PUBLISHED|] (])}} | |||
{{shortcut|WP:PUBLISHED}} | |||
'']'' means, for Misplaced Pages's purposes, any source that was ''made available to the public in some form''. The term is most commonly associated with text materials, either in traditional printed format or online; however, audio, video, and multimedia materials that have been recorded then broadcast, distributed, or archived by a reputable party may also meet the necessary criteria to be considered reliable sources. Like text, media must be produced by a reliable source and be properly cited. Additionally, an archived copy of the media must exist. It is convenient, but by no means necessary, for the archived copy to be accessible via the Internet. | |||
===Context matters=== | |||
== Unattributed material == | |||
{{shortcut|WP:CONTEXTMATTERS|WP:RSCONTEXT}} | |||
Wikipedians often report as facts things they remember hearing about or reading somewhere, but they don't remember where, and they have no corroborating evidence. It is important to seek reliable sources to verify these types of reports, and if they cannot be verified, any editor may delete or challenge them. | |||
The reliability of a source depends on context. Each source must be carefully weighed to judge whether it is reliable for the statement being made in the Misplaced Pages article and is an appropriate source for that content. | |||
In general, the more people engaged in checking facts, analyzing legal issues, and scrutinizing the writing, the more reliable the publication. Sources should {{em|directly support}} the information as it is presented in the Misplaced Pages article. | |||
It is always appropriate to ask other editors to produce their sources. '''The burden of evidence lies with the editor who has made the edit in question''', and any unsourced material may be removed by any editor. However, some editors may object if you remove material without giving people a chance to find a source, particularly when the material is not obviously wrong, absurd, or harmful. Instead of removing such material immediately, editors are encouraged to move it to the talk page, or to place the {{tl|fact}} template after the disputed word or sentence, or to tag the article by adding {{tl|not verified}} or {{tl|unsourced}} at the top of the page. | |||
See ] and ], which are policy, and ]. | |||
Information provided in passing by an otherwise reliable source or information that is not related to the principal topics of the publication may not be reliable; editors should cite sources focused on the topic at hand where possible. For example, a publisher's web site is likely to be reliable for an author's identity, date of publication, etc., but not necessarily for a critical, artistic, or commercial evaluation of the work {{See below|{{slink||Reliability in specific contexts}}, below}}. | |||
=== In biographies of living persons === | |||
Unverified material that could be construed as critical, negative or harmful in articles about living persons should be removed immediately, and should not be moved to the talk page. The same applies to sections dealing with living persons in other articles. See ] and ]. | |||
===Age matters=== | |||
== Beware false authority == | |||
{{shortcut|WP:AGE MATTERS|WP:RSAGE|WP:OLDSOURCES}} | |||
Look out for false claims of authority. Advanced degrees give authority in the topic of the degree. Web sites that have numerous footnotes may be entirely unreliable. The first question to ask yourself is, "What are the credentials and expertise of the people taking responsibility for a website?" Anyone can post anything on the web. | |||
Especially in scientific and academic fields, older sources may be inaccurate because new information has been brought to light, new theories proposed, or vocabulary changed. In areas like politics or fashion, laws or trends may make older claims incorrect. Be sure to check that older sources have not been superseded, especially if it is likely that new discoveries or developments have occurred in the last few years. In particular, ]. | |||
Sometimes sources are too ''new'' to use, such as with ] (where later reports might be more accurate), and primary sources which purport to debunk a long-standing consensus or introduce a new discovery (in which case awaiting studies that attempt to replicate the discovery might be a good idea, or reviews that validate the methods used to make the discovery). | |||
Use sources who have postgraduate degrees or demonstrable published expertise in the field they are discussing. The more reputable ones are affiliated with academic institutions. The most reputable have written textbooks in their field: these authors can be expected to have a broad, authoritative grasp of their subject. In general, college textbooks are frequently revised and try to be authoritative. High school and middle school textbooks, however, do not try to be authoritative and they are subject to political approval. | |||
Similarly for breaking news, a contemporary secondary news source can quickly become a historical primary source. Articles of recent current events ] with new secondary sources. | |||
== Exceptional claims require exceptional evidence == | |||
Certain red flags should prompt editors to closely and skeptically examine the sources for a given claim. | |||
Sources of any age may be prone to ], and this needs to be balanced out by careful editing. | |||
* Surprising or apparently important claims that are not widely known. | |||
* Surprising or apparently important reports of recent events not covered by reputable ]. | |||
* Reports of a statement by someone that seems out of character, embarrassing, controversial, or against an interest they had previously defended. | |||
* Claims not supported or claims that are contradicted by the prevailing view in the relevant academic community. Be particularly careful when proponents say there is a ] to silence them. | |||
===Usage by other sources=== | |||
== Evaluating sources == | |||
{{Shortcut|WP:UBO|WP:USEBYOTHERS}} | |||
Editors have to evaluate sources and decide which are the most reliable and authoritative. For academic topics, every field has an established system of reviews and evaluations that can be found in scholarly journals associated with that field. In history, for example, the ] reviews around 1,000 books each year. | |||
How accepted and high-quality reliable sources use a given source provides evidence, positive or negative, for its reliability and reputation. The more widespread and consistent this use is, the stronger the evidence. For example, widespread citation without comment for facts is evidence of a source's reputation and reliability for similar facts, whereas widespread doubts about reliability weigh against it. If outside citation is the main indicator of reliability, particular care should be taken to adhere to other guidelines and policies, and to not unduly represent contentious or minority claims. The goal is to reflect established views of a topic as far as we can determine them. | |||
'''' (1995) summarizes the evaluations of 27,000 books and articles in all fields of history. Editors should seek out and take advantage of these publications to help find authoritative sources. Disagreements between the authoritative sources should be indicated in the article. | |||
==Some types of sources== | |||
Also ask yourself: | |||
{{shortcut|WP:SOURCETYPES}} | |||
* Do the sources have an agenda or conflict of interest, strong views, or other bias which may color their report? Remember that conflicts of interest are not always explicitly exposed and bias is not always self-evident. However, that a source has strong views is not necessarily a reason not to use it, although editors should avoid using political groups with widely acknowledged '']'' views, like ] or ]. Groups like these may be used as primary sources only as sources about themselves or about their viewpoints, and even then with caution and sparingly. | |||
{{further|Misplaced Pages:Verifiability#Reliable sources|Misplaced Pages:Verifiability#Verifiability does not guarantee inclusion}} | |||
* Were they actually there? Be careful to distinguish between descriptions of events by eyewitnesses and by commentators. The former are primary sources; the latter secondary. Both can be reliable. | |||
Many Misplaced Pages articles rely on scholarly material. When available, academic and peer-reviewed publications, scholarly monographs, and textbooks are usually the most reliable sources. However, some scholarly material may be outdated, in competition with alternative theories, controversial within the relevant field, or largely ignored by the mainstream academic discourse because of lack of citations. Try to cite current scholarly consensus when available, recognizing that this is often absent. Reliable non-academic sources may also be used in articles about scholarly issues, particularly material from high-quality mainstream publications. Deciding which sources are appropriate depends on context. Material should be ] where ]. | |||
* Find out what other people say about your sources. | |||
* Have they reported other facts reliably, including on different subjects? Cross-check with what you already know. | |||
* Are the publications available for other editors to check? We provide sources for our readers, so they must be accessible in principle, although not necessarily online. | |||
===Scholarship=== | |||
See ] and ] for more information. | |||
{{shortcut|WP:SCHOLARSHIP}} | |||
* '''Prefer secondary sources''' – Articles should rely on secondary sources whenever possible. For example, a paper reviewing existing research, a review article, monograph, or textbook is often better than a primary research paper. When relying on primary sources, extreme caution is advised. Wikipedians should never interpret the content of primary sources for themselves ({{crossref|see ] and ]}}). | |||
* '''Reliable scholarship''' – Material such as an article, book, monograph, or research paper that has been vetted by the scholarly community is regarded as reliable, where the material has been published in reputable peer-reviewed sources or by well-regarded academic presses. | |||
* '''Dissertations''' – Completed dissertations or theses written as part of the requirements for a doctorate, and which are publicly available (most via interlibrary loan or from ]), can be used but care should be exercised, as they are often, in part, primary sources. Some of them will have gone through a process of academic peer reviewing, of varying levels of rigor, but some will not. If possible, use theses that have been cited in the literature; supervised by recognized specialists in the field; or reviewed by independent parties. Dissertations in progress have not been vetted and are not regarded as published and are thus not reliable sources as a rule. Some theses are later published in the form of scholarly monographs or peer reviewed articles, and, if available, these are usually preferable to the original thesis as sources. Masters dissertations and theses are considered reliable only if they can be shown to have had significant scholarly influence. | |||
* '''Citation counts''' – One may be able to confirm that discussion of the source has entered mainstream academic discourse by checking what scholarly citations it has received in ]es or lists such as ]. Works published in journals not included in appropriate databases, especially in fields well covered by them, might be isolated from mainstream academic discourse, though whether it is appropriate to use will depend on the context. The number of citations may be misleading if an author cites ] often. | |||
* '''Isolated studies''' – Isolated studies are usually considered tentative and may change in the light of further academic research. If the isolated study is a primary source, it should generally not be used if there are secondary sources that cover the same content. The reliability of a single study depends on the field. Avoid ] when using single studies in such fields. Studies relating to complex and ] fields, such as ], are less definitive and should be avoided. Secondary sources, such as ], textbooks, and scholarly ] are preferred when available, so as to provide proper context. | |||
* <span id="QUESTIONABLEJOURNAL"></span>'''POV and peer review in journals''' – Care should be taken with journals that exist mainly to promote a particular point of view. A claim of peer review is not an indication that the journal is respected, or that any meaningful peer review occurs. Journals that are not peer reviewed by the wider academic community should not be considered reliable, except to show the views of the groups represented by those journals.<ref group="notes">Examples include ''The Creation Research Society Quarterly'' and ''Journal of Frontier Science'' (the latter uses ). {{Webarchive|url=https://web.archive.org/web/20190420060736/http://jfspeerreview.blogspot.com/|date=2019-04-20}}).</ref> | |||

However, links to such repositories can be used as open-access links for papers which have been subsequently published in acceptable literature. | |||

===News organizations=== | ||
{{shortcut|WP:NEWSORG}} | |||
Psychological experiments have shown that memory and perception are not as reliable as we would like them to be. In one experiment, subjects were shown ] with some anomalies. Subjects could usually identify normal cards correctly even if they were displayed for a very short amount of time. But when briefly flashed a black four of hearts, for example, most subjects would, without apparent hesitation or puzzlement, incorrectly identify it as either the four of hearts or the four of spades. Subjects only became aware of the anomalous cards with longer exposures. Subjects who were aware that these strange cards were mixed in with normal cards were also much better at identifying them. {{ref|kuhn-62}} | |||
News sources often contain both factual content and opinion content. News reporting from well-established news outlets is generally considered to be reliable for statements of fact (though even the most reputable reporting sometimes contains errors). News reporting from less-established outlets is generally considered less reliable for statements of fact. Most newspapers also reprint items from ] such as ], ], ], ] or the ], which are responsible for accuracy. The agency should be cited in addition to the newspaper that reprinted it. | |||
Recent scientific experiments have begun to explain how the brain can remember imagined events as if they were real. {{ref|trudeau-23oct04}}{{ref|npr-4feb05}} Police, judges, and trial lawyers are familiar with the phenomenon that several different people witnessing the same event remember it and sometimes its crucial details differently. A common classroom | |||
exercise is to stage a sudden interruption of the class, then ask each student to write an | |||
account of what he or she saw. Most people also know that the older a memory is, the less reliable it may be. Recent studies have shown that this may be because memories are overwritten each time we access them. {{citation needed}} | |||
* Scholarly sources and high-quality non-scholarly sources are generally better than news reports for academic topics {{see above|{{slink||Scholarship}}, above}}. Press releases from organizations or journals are often used by newspapers with minimal change; such sources are ] and should not be treated differently than the underlying press release. Occasionally, some newspapers still have specialist reporters who are citable by name. ({{crossref|For topics relating to health or medicine, see {{slink||Medical claims}}, below}}.) | |||
Because conscious and unconscious biases are not always self-evident, you shouldn't necessarily be satisfied with a single source. Find another one and cross-check. If multiple independent sources agree and they have either no strong reason to be biased, or their biases are at cross purposes, then you may have a reliable account. | |||
* Otherwise reliable news sources—for example, the website of a major news organization—that publish in a blog-style format for some or all of their content may be as reliable as if published in standard news article format ({{crossref|See also {{slink|Misplaced Pages:Verifiability|Newspaper and magazine blogs}} }}). | |||
* Signals that a news organization engages in fact-checking and has a reputation for accuracy are the publication of ] and disclosures of ]. | |||
* ] is generally not as reliable as news reporting, and may not be subject to the same rigorous standards of fact-checking and accuracy (see ]).<ref>{{cite news |last=Miller |first=Laura |date=October 16, 2011 |title='Sybil Exposed': Memory, lies and therapy |work=] |publisher=Salon Media Group |url=https://www.salon.com/2011/10/16/sybil_exposed_memory_lies_and_therapy/ |accessdate=October 17, 2011 |quote=] also documents a connection between Schreiber and Terry Morris, a 'pioneer' of this genre who freely admitted to taking 'considerable license with the facts that are given to me.' |archive-url=https://web.archive.org/web/20111016222231/http://www.salon.com/2011/10/16/sybil_exposed_memory_lies_and_therapy/ |archive-date=October 16, 2011 |url-status=live |df=mdy-all }}</ref> | |||
* The reporting of rumors has a limited encyclopedic value, although in some instances verifiable information ''about'' rumors may be appropriate (i.e. if the rumors themselves are noteworthy, regardless of whether or not they are true). ] for passing along ] and ]s. | |||
* Some news organizations have used Misplaced Pages articles as a source for their work. Editors should therefore beware of ].<ref group=notes>A variety of these incidents have been documented by '']'' and others and discussed on Misplaced Pages, where incorrect details from articles added as ] or otherwise have appeared in newspapers</ref> | |||
* Whether a {{em|specific}} news story is reliable for a fact or statement should be examined on a case-by-case basis. | |||
* Multiple sources should not be asserted for any ] article. Such sources are essentially a single source. | |||
* Unless reported by a reliable source, leaks should not normally be used or cited directly in articles. | |||
==== Editorial and opinion commentary ==== | |||
However, bear in mind that we only report what reliable publications publish, although of course editors should seek to use the most authoritative sources. In accordance with Misplaced Pages's ] policy, we do not add our own opinion. | |||
{{shortcut|WP:NEWSOPED|WP:RSEDITORIAL}} | |||
Editorial commentary, analysis and ]s, whether written by the editors of the publication (]s) or outside authors (invited ]s and ] from notable figures) are reliable primary sources for ], but are rarely reliable for statements of fact {{See below|also {{slink||Statements of opinion}}, below}}. | |||
===Issues to look out for=== | |||
* Have the secondary sources used multiple independent primary sources? | |||
* Do they have an agenda or conflict of interest, strong views, or other bias which may color their report? Remember that conflicts of interest are not always explicitly exposed and bias is not always self-evident. However, that a source has strong views is not necessarily a reason not to use it, although editors should avoid using political groups with widely acknowledged extremist views, like ] or the British ]. Groups like these may be used as primary sources only i.e. as sources about themselves and their own activities, although editors should proceed with caution. Extremist groups should not be used as secondary sources. | |||
* Find out what other people say about your sources. | |||
* Have the sources reported other facts reliably, including on different subjects? Cross-check with what you already know. | |||
* Are they available to other editors to check? If not, inclusion is probably not appropriate. Note, however, that they need not be online; availability through a library is sufficient. | |||
* When taking information from opinion content, the identity of the author may help determine reliability. The opinions of specialists and recognized experts are more likely to be reliable and to reflect a significant viewpoint.<ref group=notes>Please keep in mind that any exceptional claim would require ], and this is policy.</ref> If the statement is not authoritative, attribute the opinion to the author in the text of the article and do not represent it as fact.

* Have separate editorial oversight and fact-checking processes; | |||
* Have not collaborated; | |||
* May have taken their own look at the available primary sources and used their own judgment in evaluating them. | |||
==== News aggregators ==== | |||
Even given the same primary sources, different analysts may come to different conclusions about the facts being reported. In practice, many secondary sources find and use different primary sources in the course of their research. Conscious biases, unconscious biases, and errors are not always self-evident. The best way to expose them is to cross-check with another secondary source. | |||
Some websites function partly or entirely as aggregators, reprinting items from websites of news agencies, blogs, websites, or even Misplaced Pages itself. These may constitute a curated feed or an AI-generated feed. Examples include the main pages of ] and ]. As with newspaper reprints, the original content creator is responsible for accuracy and '''reliability should be judged based on the original source'''. Direct links to the original source should be preferred over the aggregator's link. | |||

A self-published source is a published source that has not been subject to any form of independent fact-checking, or where no one stands between the writer and the act of publication. It includes personal websites, and books published by vanity presses. | |||
Although the content guidelines for ] prohibit linking to "Individual web pages that primarily exist to sell products or services", inline citations may be allowed to e-commerce pages such as that of a book on a bookseller's page or an album on its streaming-music page, in order to ] such things as titles and running times. Journalistic and academic sources are preferable, however, and e-commerce links should be replaced with reliable non-commercial sources if available. | |||
Rankings proposed by vendors (such as bestseller lists at Amazon) usually have at least one of the following problems: | |||
Anyone can create a website or pay to have a book published, and then claim to be an expert in a certain field. For that reason, self-published books, personal websites, and ] are largely not acceptable as sources. | |||
# It may be impossible to provide a stable source for the alleged ranking. | |||
# When only self-published by the vendor, i.e. no reliable independent source confirming the ranking as being relevant, the ranking would usually carry insufficient weight to be mentioned in any article. | |||
For such reasons, such rankings are usually avoided as Misplaced Pages content. | |||
===Biased or opinionated sources=== | |||
Exceptions may be when a well-known, professional researcher writing '''within his field of expertise''', or a well-known professional journalist, has produced self-published material. In some cases, these ''may'' be acceptable as sources, so long as their work has been previously published by credible, third-party publications. However, exercise caution: if the information on the professional researcher's blog is really worth reporting, someone else will have done so. | |||

{{See also|Misplaced Pages:Neutral point of view#Bias in sources}} | |||
Misplaced Pages articles are required to present a ]. However, reliable sources are not required to be neutral, unbiased, or objective. Sometimes non-neutral sources are the best possible sources for supporting information about the different viewpoints held on a subject. | |||
Common sources of bias include political, financial, religious, philosophical, or other beliefs. Although a source may be biased, it may be reliable in the specific ]. When dealing with a potentially biased source, editors should consider whether the source meets the normal requirements for reliable sources, such as editorial control, a reputation for fact-checking, and the level of independence from the topic the source is covering. Bias may make ] appropriate, as in "The feminist ] wrote that..."; "According to the Marxist economist ]..."; or "The conservative Republican presidential candidate ] believed that...". | |||
=== Reliability === | |||
Evaluate the reliability of online sources just as you would print or other more traditional sources. Neither online nor print sources deserve an automatic assumption of reliability by virtue of the medium they are printed in. All reports must be evaluated according to the processes and people that created them. | |||

===Questionable sources=== | |||
{{Shortcut|WP:QUESTIONABLE|WP:QUESTIONED}} | |||
Questionable sources are those with a poor reputation for checking the facts or with no editorial oversight. Such sources include websites and publications expressing views that are widely acknowledged as extremist, that are promotional in nature, or that rely heavily on rumors and personal opinions.<ref>{{cite web|url=http://nymag.com/selectall/2016/11/fake-facebook-news-sites-to-avoid.html|work=New York Magazine|title=Fake Facebook news sites to avoid|first=Madison|last=Malone Kircher|date=November 15, 2016|accessdate=November 15, 2016|archive-url=https://web.archive.org/web/20161116153727/http://nymag.com/selectall/2016/11/fake-facebook-news-sites-to-avoid.html|archive-date=November 16, 2016|url-status=live|df=mdy-all}}</ref> Questionable sources are generally unsuitable for citing contentious claims about third parties, which includes claims against institutions, persons living or dead, as well as more ill-defined entities. The proper uses of a questionable source are very limited. | |||
Beware of sources that sound reliable but do not have the ] that this guideline requires.<ref name=DM>An example is the '']'', which is broadly considered a questionable and prohibited source, per ].</ref> The ''Journal of 100% Reliable Factual Information'' might have a reputation for "]" behavior, which includes questionable business practices and/or peer-review processes that raise concerns about the reliability of their journal articles.<ref name=Beall1>{{cite journal |last=Beall |first=Jeffrey |authorlink=Jeffrey Beall |date=25 February 2015 |title='Predatory' Open-Access Scholarly Publishers |journal=] |url=http://eprints.rclis.org/25046/1/Rahman%20and%20Engels_%202015_Predatory%20open%20access%20journals.pdf |access-date=7 January 2016 |archive-url=https://web.archive.org/web/20160304201837/http://eprints.rclis.org/25046/1/Rahman%20and%20Engels_%202015_Predatory%20open%20access%20journals.pdf |archive-date=4 March 2016 |url-status=live |df=dmy-all }}</ref><ref name="Beall2">{{cite web|last1=Beall|first1=Jeffrey|title=Potential, possible, or probable predatory scholarly open-access publishers|url=https://scholarlyoa.com/publishers/|archive-url=https://web.archive.org/web/20170111172306/https://scholarlyoa.com/publishers/|archive-date=11 January 2017}}</ref> | |||
At the other end of the reliability scale lie personal websites, weblogs (blogs), bulletin boards, and Usenet posts, which are not acceptable as sources. Rare exceptions may be when a well-known professional person or acknowledged expert ''in a relevant field'' has set up a personal website using his or her real name. Even then, we should proceed with caution, because the information has been self-published, which means it has not been subject to any independent form of fact-checking. | |||
==== Sponsored content ==== | |||
The policy page that governs the use of sources is ]. Of self-published sources, it says: "Sources of dubious reliability are sources with a poor reputation for fact-checking, or with no fact-checking facilities or editorial oversight... Anyone can create a website or pay to have a book published. For that reason, self-published books, personal websites, and ] are largely not acceptable as sources. Exceptions may be when a well-known, professional researcher '''in a relevant field''', or a well-known professional journalist, has produced self-published material. In some cases, these ''may'' be acceptable as sources, so long as their work has been previously published by credible, third-party publications." | |||
{{Shortcut|WP:SPONSORED}} | |||
{{see also|Misplaced Pages:Conflict of interest#Covert advertising}} | |||
] is a paid advertisement that is formatted to look like an article or other piece of typical content for that outlet. The content may be directly controlled by the sponsor, or the advertiser may pay an author to create the content (e.g., ]). Advertisements can be cited, but they are ] and should be treated as ] and ] sources in articles. Reliable publications clearly indicate sponsored articles in the ] or with a ] at the top of the article. Sources that do not clearly distinguish staff-written articles from sponsored content are also questionable. | |||
] are often (but far from always) unacceptable sources. They are commonly sponsored by industry groups with a financial interest in the outcome of the research reported.

Note that Misplaced Pages itself does not currently meet the reliability guidelines; however, nothing in this guideline is meant to contravene the associated guideline: ]. Wikilink freely. | |||
Indications that an article was published in a supplement may be fairly subtle; for instance, a letter "S" added to a page number,<ref>{{cite journal |last1=Nestle |first1=Marion |title=Food company sponsorship of nutrition research and professional activities: a conflict of interest? |journal=Public Health Nutrition |date=2 January 2007 |volume=4 |issue=5 |pages=1015–1022 |doi=10.1079/PHN2001253 |pmid=11784415 |s2cid=17781732 |url=https://www.cambridge.org/core/services/aop-cambridge-core/content/view/0DC05EE7794D352882D2F089111A0449/S1368980001001069a.pdf/food_company_sponsorship_of_nutrition_research_and_professional_activities_a_conflict_of_interest.pdf |access-date=12 January 2019 |archive-url=https://web.archive.org/web/20181117105015/https://www.cambridge.org/core/services/aop-cambridge-core/content/view/0DC05EE7794D352882D2F089111A0449/S1368980001001069a.pdf/food_company_sponsorship_of_nutrition_research_and_professional_activities_a_conflict_of_interest.pdf |archive-date=17 November 2018 |url-status=live |df=dmy-all }}</ref> or "Suppl." in a reference.<ref>See ] of how to identify shill academic articles cited in Misplaced Pages.</ref> However, note that merely being published in ''<u>a</u>'' supplement is not '']'' evidence of being published in a ''<u>sponsored</u>'' supplement.

A sponsored supplement also does not necessarily involve a COI; for instance, public health agencies may also sponsor supplements. However, groups that do have a COI may hide behind layers of front organizations with innocuous names, so the ultimate funding sources should always be ascertained. | |||
=== Bulletin boards, wikis and posts to Usenet === | |||
'''Posts to bulletin boards and Usenet, wikis or messages left on blogs, are never acceptable as primary or secondary sources.''' | |||
===Self-published sources (online and paper)=== | |||
This is because we have no way of knowing who has written or posted them. In the case of wikis, the current content of an article is not guaranteed, being freely editable. | |||
{{anchor|Self-published sources|Self-published|SELF}}{{shortcut|WP:RSSELF|WP:RS/SPS}} | |||
{{main|Misplaced Pages:Verifiability#Self-published sources}} | |||
Anyone can create a ] or ] and claim to be an expert in a certain field. For that reason, self-published sources are largely not acceptable. Self-published books and newsletters, personal pages on social networking sites, ], and posts on ]s are all examples of self-published media. Self-published expert sources may be considered reliable when produced by an established expert on the subject matter, whose work in the relevant field has previously been published by reliable, independent publications. '''Never''' use self-published sources as ] about living people, even if the author is an expert, well-known professional researcher, or writer. | |||
====User-generated content==== | |||
{{anchor|User-generated|USERG|UGC|WP:ABLUELINKISNOTASOURCE}}{{shortcut|WP:UGC|WP:USERG|WP:USERGENERATED}} | |||
Content from websites whose content is largely ] is generally unacceptable. Sites with user-generated content include personal websites, personal and ] blogs (excluding ]), ]s, ]s, ], ]s, ] and ] hosting services, most ]s and other collaboratively created websites. | |||
Examples of unacceptable user-generated sources are ], ], ], ], ], ], ], ], ], ], ], ], ], ], ], ], ], and ] (]). For official accounts from celebrities and organizations on social media, see the section about self-published sources below. | |||
=== Personal websites as primary sources === | |||
A personal website (either operated by one individual or a group of individuals) or blog may be used only as a primary source, i.e., when we are writing about the owner of the website or the website itself. But even then we should proceed with great caution and should avoid relying on information from the website as a sole source. This is particularly true when the subject is controversial, and the self-publisher has no professional or academic standing. | |||
Although ]s (such as ] and ]) may be reliable when summarizing experts, the ratings and opinions of their users (including the reported rating averages) are not. | |||
=== Personal websites as secondary sources === | |||
'''Personal websites and blogs should not be used as secondary sources.''' | |||
In particular, a ] is not a reliable source. | |||
That is, they should not be used as sources of information about a person or topic other than the owner of the website. The reason personal websites are not used as secondary sources — and as primary sources only with great caution and not as a sole source if the subject is controversial — is that they are usually created by unknown individuals who have no one checking their work. They may be uninformed, misled, pushing an agenda, sloppy, relying on rumor and suspicion, or even insane; or they may be intelligent, careful people sharing their knowledge with the world. It is impossible to know which is the case. Visiting a stranger's personal website is often the online equivalent of reading an unattributed flyer on a lamp post, and should be treated accordingly. | |||
===Self-published and questionable sources as sources on themselves=== | |||
=== Partisan websites === | |||
{{shortcut|WP:SELFSOURCE}} | |||
Partisan political and religious (or anti-religious) sources should be treated with caution, although political bias is not in itself a reason not to use a source. Widely acknowledged ] political, religious, anti-religious and other websites — for example, those belonging to ], ], the ] website or the ] — should never be used as sources for Misplaced Pages, except as primary sources, that is, in articles discussing the opinions of that organization or the opinions of a larger like-minded group, but even then should be used with great caution, and should not be relied upon as a sole source. | |||

Self-published or questionable sources may be used as sources of information {{strong|about themselves}}, especially in articles about themselves, without the requirement that they be published experts in the field, so long as the following criteria are met: | |||
# The material is neither unduly self-serving nor an ]. | |||
# It does not involve claims about third parties (such as people, organizations, or other entities). | |||
# It does not involve claims about events not directly related to the subject. | |||
# There is no reasonable doubt as to its authenticity. | |||
# The Misplaced Pages article is not based primarily on such sources. | |||
These requirements also apply to pages from social networking websites such as ], ], and ]. Use of self-sourced material should be '']''; the great majority of any article must be drawn from independent sources. | |||
=== Great for easy access === | |||
Full-text online sources are preferable to offline sources if they are of similar quality and reliability, because they are easily accessed by other editors who want to check references, and by readers who simply want more information. | |||
===Spurious sources produced by machine learning=== | |||
If you find a print source that is out of copyright or that is available on compatible licensing terms, add it to ] and link to it there (in addition to the normal scholarly citation). Many significant out-of-copyright books have already been put online by other projects. | |||
{{Shortcut|WP:RSML}} | |||
In recent years, ] (ML, AI) has become a common way to generate and publish material. It may not be known or detectable that ML was used. While ML generation in itself does not necessarily disqualify a source that is properly checked by the person using it, ML has a tendency to create or "hallucinate" imaginary information, "supported" by citations that look as if they are from respectable sources but do not exist. In one case, a lawyer used ] to generate and file a legal brief that he did not check; the judge upon reviewing the case stated, "six of the submitted cases appear to be bogus judicial decisions with bogus quotes and bogus internal citations", although ChatGPT had assured the author that they were real and could "be found in reputable legal databases such as ] and ]".<ref>{{cite web | last=Moran | first=Lyle | title=Lawyer cites fake cases generated by ChatGPT in legal brief | website=Legal Dive | date=30 May 2023 | url=https://www.legaldive.com/news/chatgpt-fake-legal-cases-generative-ai-hallucinations/651557/}}</ref> Citations have been published to newspaper articles that do not exist, attributed to named reporters.<ref>{{cite web | last=Tangermann | first=Victor | title=Newspaper Alarmed When ChatGPT References Article It Never Published | website=Futurism | date=6 April 2023 | url=https://futurism.com/newspaper-alarmed-chatgpt-references-article-never-published}}</ref> Such spurious material may be generated unintentionally by writers—reporters, scientists, medical researchers, lawyers, ...—using ]s to help them to produce reports, or maliciously to generate "]". | |||
==Reliability in specific contexts== | |||
=== Self-published sources in articles about themselves === | |||
===Biographies of living persons=== | |||
Material from self-published sources, whether published online or as a book or pamphlet, may be used as sources of information about themselves in articles about themselves, so long as there is no reasonable doubt about who wrote it, and where the material is: | |||
{{main|Misplaced Pages:Biographies of living persons#Reliable sources}} | |||
* relevant to the person's notability, or, if the material is self-published by a group or organisation: relevant to the notability of that group or organisation; | |||
* not contentious; | |||
* not unduly self-serving or self-aggrandizing; | |||
* about the subject, and does not involve claims about third parties, or about events not directly related to the subject. | |||
Editors must take particular care when writing biographical material about living persons. Contentious material about a living person that is unsourced or poorly sourced should be removed immediately; do not move it to the talk page. This applies to any material related to living persons on {{em|any}} page in {{em|any}} ], not just article space. | |||
=== Finding a good source may require some effort === | |||
Until more authors publish online, and more material is uploaded, some of the most reliable and informative sources are still available only in printed form. If you can't find a good source on the web, try a local library or bookstore. Major university libraries usually have larger collections than do municipal libraries. | |||
===Primary, secondary, and tertiary sources=== | |||
Fact checking and reference-running can be time consuming. Your local ] or academic ] may not have the work cited by an article on its shelves. Often you can ask for a book through ], but this can sometimes take several weeks to do. Fortunately, new tools are now available online to make this work easier. Services such as , , and the ] allow you to search the full text of thousands of books. In addition, many similar subscription-based services may be available to though your public, college, university or graduate school libraries. | |||
{{shortcut|WP:RSPRIMARY|WP:WPNOTRS}} | |||
{{main|Misplaced Pages:No original research#Primary, secondary and tertiary sources}} | |||
Misplaced Pages articles should be based mainly on reliable ], i.e., a document or recording that relates to or discusses information originally presented elsewhere. | |||
To check on facts and citations in Misplaced Pages, these ] are powerful tools. You can search them the same way that you do in an internet search. Enter the author in ] and the title in quotation marks. If the book is in the database already, the ] will find it. If it isn’t, you may discover another work that discusses the book you seek. For subjects, enter as many terms as you can recall. The engines will display a list of pages that contain these terms. Often you will be able to verify the fact you are checking or discover a significant point of view not represented in the Misplaced Pages article. | |||
Reputable ], such as introductory-level university textbooks, almanacs, and encyclopedias, may be cited. {{anchor|Misplaced Pages is not a reliable source}}However, although Misplaced Pages articles are tertiary sources, Misplaced Pages employs no systematic mechanism for fact-checking or accuracy. Thus, {{strong|Misplaced Pages articles (and Misplaced Pages mirrors) in themselves are not reliable sources for any purpose}} (except as sources on themselves per ]). | |||
When you use one of these services, be sure to gather all the information you can find by selecting links such as “About the Book.” You should be able to assemble a ] in exactly the same way you do with a print publication. If there is an ] for the book, be sure to include it. Use the ISBN to link to the book, since several of these sites display only selected materials from the books they have online. | |||
] are often difficult to use appropriately. Although they can be both reliable and useful in certain situations, they must be used with caution in order to avoid ]. Although specific facts may be taken from primary sources, secondary sources that present the same material are preferred. Large blocks of material based purely on primary sources should be avoided. All interpretive claims, analyses, or synthetic claims about primary sources must be referenced to a secondary source, rather than original analysis of the primary-source material by Misplaced Pages editors. | |||
== Sources in languages other than English == | |||
Because this is the English Misplaced Pages, for the convenience of our readers, English-language sources should be provided whenever possible, and should always be used in preference to foreign-language sources (assuming equal quality and reliability). For example, do not use a foreign-language newspaper as a source unless there is no equivalent article in an English-language newspaper. However, foreign-language sources are acceptable in terms of verifiability, subject to the same criteria as English-language sources. | |||
When editing articles in which the use of primary sources is a concern, in-line templates, such as {{tl|primary source-inline}} and {{tl|better source}}, or article templates, such as {{tl|primary sources}} and {{tl|refimprove science}}, may be used to mark areas of concern. | |||
Keep in mind that translations are subject to error, whether performed by a Misplaced Pages editor or a professional, published translator. In principle, readers should have the opportunity to verify for themselves what the original material actually said, that it was published by a credible source, and that it was translated correctly. | |||
===Medical claims=== | |||
Therefore, when the original material is in a language other than English: | |||
{{shortcut|WP:RS/MC}} | |||
{{main|Misplaced Pages:Identifying reliable sources (medicine)}} | |||
Ideal sources for ] information include ] or ]s in reliable, independent, published sources, such as reputable ]s, widely recognised standard textbooks written by experts in a field, or ]s and position statements from nationally or internationally reputable expert bodies. It is {{em|vital}} that the biomedical information in all types of articles be based on reliable, independent, published sources and accurately reflect current medical knowledge. | |||
===Fringe theories=== | |||
* Where sources are directly quoted, published translations are generally preferred over editors performing their own translations directly. | |||
{{seealso|Misplaced Pages:Fringe theories#Parity of sources}} | |||
* Where editors use their own English translation of a non-English source as a quote in an article, there should be clear citation of the foreign-language original, so that readers can check what the original source said and the accuracy of the translation. | |||
Inclusion and exclusion of content related to fringe theories and criticism of fringe theories may be done by means of a rough parity of sources. If an article is written about a well-known topic about which many peer-reviewed articles are written, it should not include fringe theories that may seem relevant but are only sourced to obscure texts that lack peer review. Parity of sources may mean that certain fringe theories are only reliably and verifiably reported on, or criticized, in alternative venues from those that are typically considered reliable sources for scientific topics on Misplaced Pages. | |||
In an article on a fringe topic, if a notable fringe theory is primarily described by amateurs and self-published texts, verifiable and reliable criticism of the fringe theory need not be published in a peer-reviewed journal. For example, the ] article may include material from reliable websites, movies, television specials, and books that are not peer-reviewed. By ''parity of sources'', critiques of that material can likewise be gleaned from reliable websites and books that are not peer-reviewed. Of course, for any viewpoint described in an article, only reliable sources should be used; Misplaced Pages's verifiability and ] policies are not suspended simply because the topic is a fringe theory. | |||
== Advice specific to subject area == | |||
=== |
===Quotations=== | ||
{{shortcut|WP:RS/QUOTE}} | |||
Historical research involves the collection of original or “primary” documents (the job of libraries and archives), the close reading of the documents, and their interpretation in terms of larger historical issues. To be verifiable, research must be based on the primary documents. In recent decades, many more primary documents (such as letters and papers of historical figures) have been made easily available in bound volumes or online. For instance, the project at Princeton begun in 1950 has just published volume 30, reaching February 1801. More recently, primary sources have been put online, such as the complete run of the ''London Times'', the ''New York Times'' and other major newspapers. Some of these are proprietary and must be accessed through libraries; others such as , publishing of 19th century magazines, are open to the public. | |||
{{further|Misplaced Pages:Manual of Style#Quotations}} | |||
The accuracy of quoted material is paramount and the accuracy of quotations from living persons is especially sensitive. To ensure accuracy, the text of quoted material is best taken from (and cited to) the original source being quoted. If this is not possible, then the text may be taken from a reliable secondary source (ideally one that includes a citation to the original). No matter where you take the quoted text from, it is important to ]. | |||
Partisan secondary sources should be viewed with suspicion as they may misquote or quote out of context. In such cases, look for neutral corroboration from another source. | |||
Scholars doing research publish their results in books and journal articles. The books are usually published by university presses or by commercial houses like W.W. Norton and Greenwood which emulate the university press standards. Reputable history books and journal articles always include footnotes and bibliographies giving the sources used in great detail. Most journals contain book reviews by scholars that evaluate the quality of new books, and usually summarize some of their new ideas. The ''American Historical Review'' (all fields of history) and ''Journal of American History'' (US history) each publish 1000 or more full-length reviews a year. Many of the major journals are online, as far back as 1885, especially through . A good book or article will spell out the historiographical debates that are ongoing, and alert readers to other major studies. | |||
Any analysis or interpretation of the quoted material, however, should rely on a secondary source ({{crossref|see ]}}). | |||
On many topics, there are different interpretive schools which use the same documents and facts but use different frameworks and come to different conclusions. Useful access points include: scholar.google.com and books.google.com, and (through libraries) ABC-CLIO’s two abstract services, ''American: History and Life'' (for journal articles and book reviews dealing with the US and Canada), and ''Historical Abstracts'' (for the rest of the world.) Research libraries will hold paper guides to authoritative sources. The most useful is ''The American Historical Association's Guide to Historical Literature,'' edited by Mary Beth Norton and Pamela Gerardi 2 vol (1995), which is an annotated bibliography of authoritative sources in all fields of history. | |||
===Academic consensus=== | |||
There are many other sources of historical information, but their authority varies. A recent trend is a proliferation of specialized encyclopedias on historical topics. These are edited by experts who commission scholars to write the articles, and then review each article for quality control. They can be considered authoritative for Misplaced Pages. ''General'' encyclopedias, like the ''Encyclopedia Britannica'' or ''Encarta'', sometimes have authoritative signed articles written by specialists and including references. However, unsigned entries are written in batches by freelancers and must be used with caution. | |||
{{Shortcut|WP:RS/AC}} | |||
A statement that all or most scientists or scholars hold a certain view requires reliable sourcing that directly says that all or most scientists or scholars hold that view. Otherwise, individual opinions should be identified as those of particular, named sources. Editors should avoid original research especially with regard to making blanket statements based on ]. Stated simply, any statement in Misplaced Pages that academic consensus exists on a topic must be sourced rather than being based on the opinion or assessment of editors. ]s, especially those printed in academic review journals that survey the literature, can help clarify academic consensus. | |||
===Statements of opinion=== | |||
College textbooks are updated every few years, are evaluated by many specialists, and usually try to keep abreast of the scholarship, but they are often without footnotes and usually do not spell out the historiographical debates. Textbooks at the K-12 level do not try to be authoritative and should be avoided by Misplaced Pages editors. Every place has guide books, which usually contain a capsule history of the area, but the great majority do not pretend to be authoritative. On many historical topics there are memoirs and oral histories that specialists consult with caution, for they are filled with stories that people wish to remember — and usually recall without going back to the original documentation. Editors should use them with caution. | |||
{{Shortcut|WP:RSOPINION}} | |||
Some sources may be considered reliable for statements as to their author's opinion, but not for statements asserted as fact. For example, an inline qualifier might say " says....". A prime example of this is ]s in mainstream newspapers. When using them, it is best to clearly attribute the opinions in the text to the author and make it clear to the readers that they are reading an opinion {{See above|also {{slink||Editorial and opinion commentary}}, above}}. | |||
There is an important exception to sourcing statements of fact {{em|or}} opinion: {{strong|Never use ] books, ]s, websites, webforums, ]s and ] as a source for material about a living person}}, unless written or published by the subject of the biographical material. "Self-published blogs" in this context refers to personal and group blogs; see {{section link|Misplaced Pages:Biographies of living persons|Reliable sources}} and {{section link|Misplaced Pages:Biographies of living persons|Using the subject as a self-published source}}. | |||
The general public mostly gets its history from novels, films, TV shows, or tour guides at various sites. These sources are full of rumor and gossip and false or exaggerated tales. They tend to present rosy-colored histories in which the well-known names are portrayed heroically. Almost always editors can find much more authoritative sources. | |||
The exception for statements ABOUTSELF is covered at {{Section link|Misplaced Pages:Verifiability#Self-published or questionable sources as sources on themselves}}. | |||

Breaking-news reports often contain serious inaccuracies. As an electronic publication, Misplaced Pages can and should be up to date, but ] and it does not need to go into all details of a current event in real time. It is better to wait a day or two after an event before adding details to the encyclopedia, than to help spread potentially false rumors. This gives journalists time to collect more information and verify claims, and for investigative authorities to make official announcements. The '']'' ''Breaking News Consumer's Handbook''<ref>{{Cite web|url=https://www.wnyc.org/story/breaking-news-consumers-handbook-pdf/|title=The Breaking News Consumer's Handbook {{!}} On the Media|website=WNYC|language=en|access-date=2019-03-14|archive-url=https://web.archive.org/web/20190228030728/https://www.wnyc.org/story/breaking-news-consumers-handbook-pdf/|archive-date=2019-02-28|url-status=live}}</ref> contains several suggestions to avoid spreading unreliable and false information. These include: distrust anonymous sources, unconfirmed reports, and reports attributed to other news media; seek multiple independent sources which independently verify; seek verified eyewitness reports; and be wary of potential hoaxes. With mass shootings, remain skeptical of early reports of additional attackers, coordinated plans, and bomb threats. | |||
When editing a current-event article, keep in mind the tendency towards ]. Claims sourced to initial news reports should be immediately replaced with better-researched and verified sources as soon as such articles are published, especially if original reports contained inaccuracies. All breaking news stories, without exception, are primary sources, and must be treated with caution: see ''{{Section link|Misplaced Pages:No original research|Primary, secondary and tertiary sources}}'', ''{{Section link|Misplaced Pages:Identifying_and_using_primary_sources|Examples of news reports as primary sources}}''. | |||
==== Cite peer-reviewed scientific publications and check community consensus ==== | |||
Scientific journals are the best place to find primary source articles about scientific experiments, including medical studies. Any scientific journal that insists on being taken seriously is ]ed, which means that independent experts in the field are asked to (usually anonymously) comment on articles before they are published. This usually results in corrections and improvement, sometimes substantial. Many articles are excluded from peer-reviewed journals because they report unimportant or questionable research, in the opinion of the editors. | |||
The {{tl|current}}, {{tl|recent death}}, or another ] may be added to the top of articles related to a breaking-news event to alert readers that some information in the article may be inaccurate and to draw attention to the need to add improved sources as they become available. These templates should not be used, however, to mark articles on subjects or persons in the news. If they were, hundreds of thousands of articles would have such a template, without any significant advantage ({{crossref|see also ]}}). | |||
In particular be careful of material in a journal that is not peer-reviewed reporting material in a different field. In the ] affair a law journal edited by students accepted a paper making claims on Internet pornography which were in effect social science experiments. See ] for a hoax played on a journal of literary criticism which inadvisedly accepted a nonsense paper bristling with physics jargon. | |||

: ''The fact that a statement is published in a refereed journal does not make it true.'' | |||
===Headlines=== | |||
Even a well-designed experiment or study can produce flawed results. (For example, see the ] published in the very prestigious journal '']''). Also, peer review is poor at uncovering deliberate fraud. The ] bears witness to that. | |||
{{Shortcut|WP:HEADLINES|WP:RSHEADLINES}} | |||
News ]—including ]—are not a reliable source. If the information is supported by the body of the source, then cite it from the body. Headlines are written to grab readers' attention quickly and briefly; they may be overstated or lack context, and sometimes contain exaggerations or sensationalized claims with the intention of attracting readers to an otherwise reliable article. They are often written by copy editors instead of the researchers and journalists who wrote the articles. | |||
== Deprecated sources == | |||
A second, informal part of ] occurs ''after publication''. Colleagues in the field will read the journal article and discuss it in various forums, including other journals in the same field and often later articles in the same journal. They may find evident flaws in the procedure used just by reading the article and applying their experience, or it may take a long process of trying to reproduce the results by similar or completely different means for the ] to determine that the original results were corrupted by some undetermined methodological problem, or to rigorously confirm the original result. The most reliable source for scientific information is the prevailing "scientific consensus". | |||
{{Shortcut|WP:RSDEPRECATED}} | |||
{{main|Misplaced Pages:Deprecated sources}} | |||
Short of polling a group of experts in the field, determining the scientific consensus can be accomplished by following what is accepted as the state of knowledge in review articles. | |||
{{see also|Misplaced Pages:Reliable sources/Perennial sources|Misplaced Pages:Spam blacklist}} | |||
A number of sources are deprecated on Misplaced Pages. That means they should not be used, unless there is a specific consensus to do so. Deprecation happens through a ], usually at the ]. It is reserved for sources that have a substantial history of fabrication or other serious factual accuracy issues (e.g. promoting unfounded ]), usually when there are large numbers of references to the source giving rise to concerns about the integrity of information in the encyclopedia. | |||
A deprecated source should not be used to support factual claims. While there are exceptions for ], these are rarely appropriate outside articles on the source itself. In general articles, commentary on a deprecated source's opinion should be drawn from independent secondary sources. Including a claim or statement by a deprecated source that is not covered by reliable sources risks giving ] to a ]. | |||
There is sometimes no one prevailing view because the available evidence does not yet point to a single answer. Because Misplaced Pages not only aims to be accurate, but also useful, it generally tries to explain the theories and empirical justification for each school of thought, '''with reference to published sources'''. Editors should not, however, create arguments themselves in favor of, or against, any particular theory or position. See ], which is policy. | |||
Some sources are blacklisted, and can not be used at all. Blacklisting is generally reserved for sources which are added abusively, such as state-sponsored fake news sites with a history of addition by ]s. Specific blacklisted sources can be locally whitelisted; see ] for other details about blacklisting. | |||
: ''Just because something is not an accepted scientific fact, as determined by the prevailing scientific consensus, does not mean that it should not be reported and referenced in Misplaced Pages.'' | |||
== See also == | |||
However, although significant-minority views are welcome in Misplaced Pages, the views of tiny minorities need not be reported. See ]. Significant-minority views should be reported as that, and should not be given the same amount of space in an article as the majority view. | |||

==== Avoid citing the popular press ==== | |||
{{div col}} | |||
The popular press generally does not cover science well. Articles in newspapers and popular magazines generally lack the context to judge experimental results. They tend to overemphasize the certainty of any result, for instance presenting a new experimental medicine as the "discovery of the cure" of a disease. Also, newspapers and magazines frequently publish articles about scientific results before those results have been peer-reviewed or reproduced by other experimenters. They also tend not to report adequately on the methodology of scientific work, or the degree of experimental error. Thus, popular newspaper and magazine sources are generally not reliable sources for science and medicine articles. | |||

=== Locating reliable sources === | |||
What can a popular-press article provide? Often, the most useful thing is the name of the head researcher involved in a project, and the name of his or her institution. For instance, a newspaper article quoting Joe Smith of the Woods Hole Oceanographic Institution regarding whales' response to sonar gives you a strong suggestion of where to go to find more: look up his work on the subject. Rather than citing the newspaper article, cite his published papers. | |||

==Notes== | |||
Keep in mind that even a reputable journal may occasionally post a retraction of an experimental result. Articles may be selected on the grounds that they are interesting or highly promising, not merely because they seem reliable. | |||
{{reflist|group=notes}} | |||
==== arXiv preprints and conference abstracts ==== | |||
There are a growing number of sources on the web that archive the full text of articles before they have been formally published in a journal, and publish ] of papers to be presented at conferences. Editors should be aware that preprints in such collections, like those in the ] collection, may or may not be accepted by the journal for which they were written — in some cases they are written solely for the arXiv and are never submitted for publication. Similarly, papers presented at conferences may not merit publication after presentation at the conference. | |||
For this reason, arXiv (or similar) preprints and conference abstracts should be considered to be self-published, as they have not been published by a third-party source, and should be treated in the same way as other self-published material. See the section above on ]. Most of them are also ''primary sources'', to be treated with the caution as described in various sections of this guideline. | |||
==== Evaluating experiments and studies ==== | |||
There are certain techniques that scientists use to prevent results from being contaminated by certain kinds of common errors, and to help others replicate results. | |||
* ] | |||
** ] controls | |||
** Ensuring demographic information aligns with the general population to check that the sample is sufficiently random | |||
** ] medical studies | |||
* Present a high degree of detail about the design and implementation of the experiment; don't just present the results. | |||
* Make raw data available; don't just present conclusions. | |||
=== Statistics === | |||
Statistical information is easily and often misinterpreted by the public, by journalists, and by scientists. It should be checked and explained with the utmost care, with reference to published sources. | |||
See ], ], and ] for common errors and abuses. | |||
=== Law === | |||
First of all, remember there are several legal traditions and that laws are only valid in their own jurisdiction. An expert on Californian and U.S. federal law is not qualified to comment on French or German law. The opinion of local experts is therefore preferred, in general, to that of outside commentators. | |||
Some of the commentary on laws and court decisions is heavily slanted for political purposes, with ample use of ], which should not be taken at face value. For instance, people opposing certain criminal procedure laws may claim that they "suppress the ]" or "suspend the ]". Such comments, while they can be reported as opinion, should not be represented as fact.<!-- what does "some of the commentary on laws" mean? --> | |||
When discussing legal texts, it is in general better to quote from the text, or quote from reputable jurists, than to quote from newspaper reports, although newspaper reports in good newspapers are acceptable too. The journalist who wrote the paper may not be trained as a lawyer, although s/he may have access to a wider variety of legal experts than many lawyers do, so judge the quality of the report according to how well that journalist, or that newspaper, has covered legal issues in the past. | |||
=== Popular culture and fiction === | |||
Articles related to popular culture and fiction must be backed up by reliable sources like all other articles. However, due to the subject matter, many may not be discussed in the same academic contexts as science, law, philosophy and so on. Therefore, the most reliable material available is expected, but sources for these topics should not be held to as strict a standard. See ]. | |||
However, keep in mind that personal websites, wikis, and posts on bulletin boards, Usenet and blogs should still not be used as secondary sources. | |||

Misplaced Pages articles should be based on reliable, published sources, making sure that all majority and significant minority views that have appeared in those sources are covered (see Misplaced Pages:Neutral point of view). If no reliable sources can be found on a topic, Misplaced Pages should not have an article on it.
This guideline discusses the reliability of various types of sources. The policy on sourcing is Misplaced Pages:Verifiability, which requires inline citations for any material challenged or likely to be challenged, and for all quotations. The verifiability policy is strictly applied to all material in the mainspace—articles, lists, and sections of articles—without exception, and in particular to biographies of living persons, which states:
Contentious material about living persons (or, in some cases, recently deceased) that is unsourced or poorly sourced—whether the material is negative, positive, neutral, or just questionable—must be removed immediately and without waiting for discussion.
In the event of a contradiction between this guideline and our policies regarding sourcing and attribution, the policies take priority and editors should seek to resolve the discrepancy. Other policies relevant to sourcing are Misplaced Pages:No original research and Misplaced Pages:Biographies of living persons. For questions about the reliability of particular sources, see Misplaced Pages:Reliable sources/Noticeboard.
Overview
Further information: Misplaced Pages:Neutral point of view § Good research ShortcutArticles should be based on reliable, independent, published sources with a reputation for fact-checking and accuracy. This means that we publish only the analysis, views, and opinions of reliable authors, and not those of Wikipedians, who have read and interpreted primary source material for themselves. The following examples cover only some of the possible types of reliable sources and source reliability issues, and are not intended to be exhaustive. Proper sourcing always depends on context; common sense and editorial judgment are an indispensable part of the process.
Definition of a source
ShortcutA source is where the material comes from. For example, a source could be a book or a webpage. A source can be reliable or unreliable for the material it is meant to support. Some sources, such as unpublished texts and an editor's own personal experience, are prohibited.
When editors talk about sources that are being cited on Misplaced Pages, they might be referring to any one of these three concepts:
- The piece of work itself (the article, book)
- The creator of the work (the writer, journalist)
- The publisher of the work (for example, Random House or Cambridge University Press)
Any of the three can affect reliability. Reliable sources may be published materials with a reliable publication process, authors who are regarded as authoritative in relation to the subject, or both. These qualifications should be demonstrable to other people.
Definition of published
"WP:PUBLISHED" redirects here. Not to be confused with Misplaced Pages:Published (WP:PUBLISH). ShortcutPublished means, for Misplaced Pages's purposes, any source that was made available to the public in some form. The term is most commonly associated with text materials, either in traditional printed format or online; however, audio, video, and multimedia materials that have been recorded then broadcast, distributed, or archived by a reputable party may also meet the necessary criteria to be considered reliable sources. Like text, media must be produced by a reliable source and be properly cited. Additionally, an archived copy of the media must exist. It is convenient, but by no means necessary, for the archived copy to be accessible via the Internet.
Context matters
ShortcutsThe reliability of a source depends on context. Each source must be carefully weighed to judge whether it is reliable for the statement being made in the Misplaced Pages article and is an appropriate source for that content.
In general, the more people engaged in checking facts, analyzing legal issues, and scrutinizing the writing, the more reliable the publication. Sources should directly support the information as it is presented in the Misplaced Pages article.
Information provided in passing by an otherwise reliable source or information that is not related to the principal topics of the publication may not be reliable; editors should cite sources focused on the topic at hand where possible. For example, a publisher's web site is likely to be reliable for an author's identity, date of publication, etc., but not necessarily for a critical, artistic, or commercial evaluation of the work (see § Reliability in specific contexts, below).
Age matters
ShortcutsEspecially in scientific and academic fields, older sources may be inaccurate because new information has been brought to light, new theories proposed, or vocabulary changed. In areas like politics or fashion, laws or trends may make older claims incorrect. Be sure to check that older sources have not been superseded, especially if it is likely that new discoveries or developments have occurred in the last few years. In particular, newer sources are generally preferred in medicine.
Sometimes sources are too new to use, such as with breaking news (where later reports might be more accurate), and primary sources which purport to debunk a long-standing consensus or introduce a new discovery (in which case awaiting studies that attempt to replicate the discovery might be a good idea, or reviews that validate the methods used to make the discovery).
Similarly for breaking news, a contemporary secondary news source can quickly become a historical primary source. Articles of recent current events must be periodically updated with new secondary sources.
Sources of any age may be prone to recentism, and this needs to be balanced out by careful editing.
Usage by other sources
ShortcutsHow accepted and high-quality reliable sources use a given source provides evidence, positive or negative, for its reliability and reputation. The more widespread and consistent this use is, the stronger the evidence. For example, widespread citation without comment for facts is evidence of a source's reputation and reliability for similar facts, whereas widespread doubts about reliability weigh against it. If outside citation is the main indicator of reliability, particular care should be taken to adhere to other guidelines and policies, and to not unduly represent contentious or minority claims. The goal is to reflect established views of a topic as far as we can determine them.
Some types of sources
Shortcut Further information: Misplaced Pages:Verifiability § Reliable sources, and Misplaced Pages:Verifiability § Verifiability does not guarantee inclusionMany Misplaced Pages articles rely on scholarly material. When available, academic and peer-reviewed publications, scholarly monographs, and textbooks are usually the most reliable sources. However, some scholarly material may be outdated, in competition with alternative theories, controversial within the relevant field, or largely ignored by the mainstream academic discourse because of lack of citations. Try to cite current scholarly consensus when available, recognizing that this is often absent. Reliable non-academic sources may also be used in articles about scholarly issues, particularly material from high-quality mainstream publications. Deciding which sources are appropriate depends on context. Material should be attributed in-text where sources disagree.
Scholarship
Shortcut- Prefer secondary sources – Articles should rely on secondary sources whenever possible. For example, a paper reviewing existing research, a review article, monograph, or textbook is often better than a primary research paper. When relying on primary sources, extreme caution is advised. Wikipedians should never interpret the content of primary sources for themselves (see Misplaced Pages:No original research and Misplaced Pages:Neutral point of view).
- Reliable scholarship – Material such as an article, book, monograph, or research paper that has been vetted by the scholarly community is regarded as reliable, where the material has been published in reputable peer-reviewed sources or by well-regarded academic presses.
- Dissertations – Completed dissertations or theses written as part of the requirements for a doctorate, and which are publicly available (most via interlibrary loan or from ProQuest), can be used but care should be exercised, as they are often, in part, primary sources. Some of them will have gone through a process of academic peer reviewing, of varying levels of rigor, but some will not. If possible, use theses that have been cited in the literature; supervised by recognized specialists in the field; or reviewed by independent parties. Dissertations in progress have not been vetted and are not regarded as published and are thus not reliable sources as a rule. Some theses are later published in the form of scholarly monographs or peer reviewed articles, and, if available, these are usually preferable to the original thesis as sources. Masters dissertations and theses are considered reliable only if they can be shown to have had significant scholarly influence.
- Citation counts – One may be able to confirm that discussion of the source has entered mainstream academic discourse by checking what scholarly citations it has received in citation indexes or lists such as DOAJ. Works published in journals not included in appropriate databases, especially in fields well covered by them, might be isolated from mainstream academic discourse, though whether it is appropriate to use will depend on the context. The number of citations may be misleading if an author cites themselves often.
- Isolated studies – Isolated studies are usually considered tentative and may change in the light of further academic research. If the isolated study is a primary source, it should generally not be used if there are secondary sources that cover the same content. The reliability of a single study depends on the field. Avoid undue weight when using single studies in such fields. Studies relating to complex and abstruse fields, such as medicine, are less definitive and should be avoided. Secondary sources, such as meta-analyses, textbooks, and scholarly review articles are preferred when available, so as to provide proper context.
- POV and peer review in journals – Care should be taken with journals that exist mainly to promote a particular point of view. A claim of peer review is not an indication that the journal is respected, or that any meaningful peer review occurs. Journals that are not peer reviewed by the wider academic community should not be considered reliable, except to show the views of the groups represented by those journals.
- Predatory journals – Predatory journals are of very low quality and have only token peer-review, if any. These journals publish whatever is submitted if the author is willing to pay a fee. Some go so far as to mimic the names of established journals (Journal hijacking). The lack of reliable peer review implies that articles in such journals should at best be treated similarly to self-published sources. If you are unsure about the quality of a journal, check that the editorial board is based in a respected accredited university, and that it is included in the relevant high-quality citation index—be wary of indexes that merely list almost all publications, and do not vet the journals they list. (See also Misplaced Pages:Identifying reliable sources (medicine) § Predatory journals.)
- ShortcutsPreprints – Preprints, such as those available on repositories like arXiv, medRxiv, bioRxiv, or Zenodo are not reliable sources. Research that has not been peer-reviewed is akin to a blog, as anybody can post it online. Their use is generally discouraged, unless they meet the criteria for acceptable use of self-published sources, and will always fail higher sourcing requirements like WP:MEDRS. However, links to such repositories can be used as open-access links for papers which have been subsequently published in acceptable literature.
News organizations
ShortcutNews sources often contain both factual content and opinion content. News reporting from well-established news outlets is generally considered to be reliable for statements of fact (though even the most reputable reporting sometimes contains errors). News reporting from less-established outlets is generally considered less reliable for statements of fact. Most newspapers also reprint items from news agencies such as Reuters, Interfax, Agence France-Presse, United Press International or the Associated Press, which are responsible for accuracy. The agency should be cited in addition to the newspaper that reprinted it.
- Scholarly sources and high-quality non-scholarly sources are generally better than news reports for academic topics (see § Scholarship, above). Press releases from organizations or journals are often used by newspapers with minimal change; such sources are churnalism and should not be treated differently than the underlying press release. Occasionally, some newspapers still have specialist reporters who are citable by name. (For topics relating to health or medicine, see § Medical claims, below.)
- Otherwise reliable news sources—for example, the website of a major news organization—that publish in a blog-style format for some or all of their content may be as reliable as if published in standard news article format (See also Misplaced Pages:Verifiability § Newspaper and magazine blogs).
- Signals that a news organization engages in fact-checking and has a reputation for accuracy are the publication of corrections and disclosures of conflicts of interest.
- Human interest reporting is generally not as reliable as news reporting, and may not be subject to the same rigorous standards of fact-checking and accuracy (see Junk food news).
- The reporting of rumors has a limited encyclopedic value, although in some instances verifiable information about rumors may be appropriate (i.e. if the rumors themselves are noteworthy, regardless of whether or not they are true). Misplaced Pages is not the place for passing along gossip and rumors.
- Some news organizations have used Misplaced Pages articles as a source for their work. Editors should therefore beware of circular sourcing.
- Whether a specific news story is reliable for a fact or statement should be examined on a case-by-case basis.
- Multiple sources should not be asserted for any wire service article. Such sources are essentially a single source.
- Unless reported by a reliable source, leaks should not normally be used or cited directly in articles.
Editorial and opinion commentary
ShortcutsEditorial commentary, analysis and opinion pieces, whether written by the editors of the publication (editorials) or outside authors (invited op-eds and letters to the editor from notable figures) are reliable primary sources for statements attributed to that editor or author, but are rarely reliable for statements of fact (see also § Statements of opinion, below).
- When taking information from opinion content, the identity of the author may help determine reliability. The opinions of specialists and recognized experts are more likely to be reliable and to reflect a significant viewpoint. If the statement is not authoritative, attribute the opinion to the author in the text of the article and do not represent it as fact. Reviews for books, movies, art, etc. can be opinion, summary, or scholarly pieces.
- Some news organizations may not publish their editorial policies.
News aggregators
Some websites function partly or entirely as aggregators, reprinting items from websites of news agencies, blogs, websites, or even Misplaced Pages itself. These may constitute a curated feed or an AI-generated feed. Examples include the main pages of MSN and Yahoo News. As with newspaper reprints, the original content creator is responsible for accuracy and reliability should be judged based on the original source. Direct links to the original source should be preferred over the aggregator's link.
Vendor and e-commerce sources
ShortcutsAlthough the content guidelines for external links prohibit linking to "Individual web pages that primarily exist to sell products or services", inline citations may be allowed to e-commerce pages such as that of a book on a bookseller's page or an album on its streaming-music page, in order to verify such things as titles and running times. Journalistic and academic sources are preferable, however, and e-commerce links should be replaced with reliable non-commercial sources if available.
Rankings proposed by vendors (such as bestseller lists at Amazon) usually have at least one of the following problems:
- It may be impossible to provide a stable source for the alleged ranking.
- When only self-published by the vendor, i.e. no reliable independent source confirming the ranking as being relevant, the ranking would usually carry insufficient weight to be mentioned in any article.
For such reasons, such rankings are usually avoided as Misplaced Pages content.
Biased or opinionated sources
Shortcuts See also: Misplaced Pages:Neutral point of view § Bias in sourcesMisplaced Pages articles are required to present a neutral point of view. However, reliable sources are not required to be neutral, unbiased, or objective. Sometimes non-neutral sources are the best possible sources for supporting information about the different viewpoints held on a subject.
Common sources of bias include political, financial, religious, philosophical, or other beliefs. Although a source may be biased, it may be reliable in the specific context. When dealing with a potentially biased source, editors should consider whether the source meets the normal requirements for reliable sources, such as editorial control, a reputation for fact-checking, and the level of independence from the topic the source is covering. Bias may make in-text attribution appropriate, as in "The feminist Betty Friedan wrote that..."; "According to the Marxist economist Harry Magdoff..."; or "The conservative Republican presidential candidate Barry Goldwater believed that...".
Questionable and self-published sources
Main page: Misplaced Pages:Verifiability § Reliable sourcesQuestionable sources
ShortcutsQuestionable sources are those with a poor reputation for checking the facts or with no editorial oversight. Such sources include websites and publications expressing views that are widely acknowledged as extremist, that are promotional in nature, or that rely heavily on rumors and personal opinions. Questionable sources are generally unsuitable for citing contentious claims about third parties, which includes claims against institutions, persons living or dead, as well as more ill-defined entities. The proper uses of a questionable source are very limited.
Beware of sources that sound reliable but do not have the reputation for fact-checking and accuracy that this guideline requires. The Journal of 100% Reliable Factual Information might have a reputation for "predatory" behavior, which includes questionable business practices and/or peer-review processes that raise concerns about the reliability of their journal articles.
Sponsored content
Shortcut See also: Misplaced Pages:Conflict of interest § Covert advertisingSponsored content is a paid advertisement that is formatted to look like an article or other piece of typical content for that outlet. The content may be directly controlled by the sponsor, or the advertiser may pay an author to create the content (e.g., influencer marketing). Advertisements can be cited, but they are non-independent and should be treated as self-published and primary sources in articles. Reliable publications clearly indicate sponsored articles in the byline or with a disclaimer at the top of the article. Sources that do not clearly distinguish staff-written articles from sponsored content are also questionable.
Symposia and supplements to academic journals are often (but far from always) unacceptable sources. They are commonly sponsored by industry groups with a financial interest in the outcome of the research reported. They may lack independent editorial oversight and peer review, with no supervision of content by the parent journal. Such articles do not share the reliability of their parent journal, being essentially paid ads disguised as academic articles. Such supplements, and those that do not clearly declare their editorial policy and conflicts of interest, should not be cited.
Indications that an article was published in a supplement may be fairly subtle; for instance, a letter "S" added to a page number, or "Suppl." in a reference. However, note that merely being published in a supplement is not prima facie evidence of being published in a sponsored supplement. Many, if not most, supplements are perfectly legitimate sources, such as the Astronomy & Astrophysics Supplement Series, Nuclear Physics B: Proceedings Supplements, Supplement to the London Gazette, or The Times Higher Education Supplement. A sponsored supplement also does not necessarily involve a COI; for instance, public health agencies may also sponsor supplements. However, groups that do have a COI may hide behind layers of front organizations with innocuous names, so the ultimate funding sources should always be ascertained.
Self-published sources (online and paper)
Shortcuts Main page: Misplaced Pages:Verifiability § Self-published sourcesAnyone can create a personal web page or publish their own book and claim to be an expert in a certain field. For that reason, self-published sources are largely not acceptable. Self-published books and newsletters, personal pages on social networking sites, tweets, and posts on Internet forums are all examples of self-published media. Self-published expert sources may be considered reliable when produced by an established expert on the subject matter, whose work in the relevant field has previously been published by reliable, independent publications. Never use self-published sources as third-party sources about living people, even if the author is an expert, well-known professional researcher, or writer.
User-generated content
ShortcutsContent from websites whose content is largely user-generated is generally unacceptable. Sites with user-generated content include personal websites, personal and group blogs (excluding newspaper and magazine blogs), content farms, Internet forums, social media sites, fansites, video and image hosting services, most wikis and other collaboratively created websites.
Examples of unacceptable user-generated sources are Ancestry.com, Discogs, Facebook, Famous Birthdays, Fandom, Find a Grave, Goodreads, IMDb, Instagram, Know Your Meme, Reddit, Snapchat, TikTok, Tumblr, TV Tropes, Twitter, WhoSampled, and Misplaced Pages (self referencing). For official accounts from celebrities and organizations on social media, see the section about self-published sources below.
Although review aggregators (such as Rotten Tomatoes and Metacritic) may be reliable when summarizing experts, the ratings and opinions of their users (including the reported rating averages) are not.
In particular, a wikilink is not a reliable source.
Self-published and questionable sources as sources on themselves
Shortcut See also: Misplaced Pages:Verifiability § Self-published or questionable sources as sources on themselvesIt has been suggested that this section be merged into Misplaced Pages:Verifiability#Self-published or questionable sources as sources on themselves. (Discuss) Proposed since December 2023. |
Self-published or questionable sources may be used as sources of information about themselves, especially in articles about themselves, without the requirement that they be published experts in the field, so long as the following criteria are met:
- The material is neither unduly self-serving nor an exceptional claim.
- It does not involve claims about third parties (such as people, organizations, or other entities).
- It does not involve claims about events not directly related to the subject.
- There is no reasonable doubt as to its authenticity.
- The Misplaced Pages article is not based primarily on such sources.
These requirements also apply to pages from social networking websites such as Twitter, Tumblr, and Facebook. Use of self-sourced material should be de minimis; the great majority of any article must be drawn from independent sources.
Spurious sources produced by machine learning
ShortcutIn recent years, machine learning (ML, AI) has become a common way to generate and publish material. It may not be known or detectable that ML was used. While ML generation in itself does not necessarily disqualify a source that is properly checked by the person using it, ML has a tendency to create or "hallucinate" imaginary information, "supported" by citations that look as if they are from respectable sources but do not exist. In one case, a lawyer used ChatGPT to generate and file a legal brief that he did not check; the judge upon reviewing the case stated, "six of the submitted cases appear to be bogus judicial decisions with bogus quotes and bogus internal citations", although ChatGPT had assured the author that they were real and could "be found in reputable legal databases such as LexisNexis and Westlaw". Citations have been published to newspaper articles that do not exist, attributed to named reporters. Such spurious material may be generated unintentionally by writers—reporters, scientists, medical researchers, lawyers, ...—using chatbots to help them to produce reports, or maliciously to generate "fake news".
Reliability in specific contexts
Biographies of living persons
Main page: Misplaced Pages:Biographies of living persons § Reliable sourcesEditors must take particular care when writing biographical material about living persons. Contentious material about a living person that is unsourced or poorly sourced should be removed immediately; do not move it to the talk page. This applies to any material related to living persons on any page in any namespace, not just article space.
Primary, secondary, and tertiary sources
Shortcuts Main page: Misplaced Pages:No original research § Primary, secondary and tertiary sourcesMisplaced Pages articles should be based mainly on reliable secondary sources, i.e., a document or recording that relates to or discusses information originally presented elsewhere.
Reputable tertiary sources, such as introductory-level university textbooks, almanacs, and encyclopedias, may be cited. However, although Misplaced Pages articles are tertiary sources, Misplaced Pages employs no systematic mechanism for fact-checking or accuracy. Thus, Misplaced Pages articles (and Misplaced Pages mirrors) in themselves are not reliable sources for any purpose (except as sources on themselves per WP:SELFSOURCE).
Primary sources are often difficult to use appropriately. Although they can be both reliable and useful in certain situations, they must be used with caution in order to avoid original research. Although specific facts may be taken from primary sources, secondary sources that present the same material are preferred. Large blocks of material based purely on primary sources should be avoided. All interpretive claims, analyses, or synthetic claims about primary sources must be referenced to a secondary source, rather than original analysis of the primary-source material by Misplaced Pages editors.
When editing articles in which the use of primary sources is a concern, in-line templates, such as {{primary source-inline}} and {{better source}}, or article templates, such as {{primary sources}} and {{refimprove science}}, may be used to mark areas of concern.
Medical claims
Shortcut Main page: Misplaced Pages:Identifying reliable sources (medicine)Ideal sources for biomedical information include general or systematic reviews in reliable, independent, published sources, such as reputable medical journals, widely recognised standard textbooks written by experts in a field, or medical guidelines and position statements from nationally or internationally reputable expert bodies. It is vital that the biomedical information in all types of articles be based on reliable, independent, published sources and accurately reflect current medical knowledge.
Fringe theories
See also: Misplaced Pages:Fringe theories § Parity of sourcesInclusion and exclusion of content related to fringe theories and criticism of fringe theories may be done by means of a rough parity of sources. If an article is written about a well-known topic about which many peer-reviewed articles are written, it should not include fringe theories that may seem relevant but are only sourced to obscure texts that lack peer review. Parity of sources may mean that certain fringe theories are only reliably and verifiably reported on, or criticized, in alternative venues from those that are typically considered reliable sources for scientific topics on Misplaced Pages.
In an article on a fringe topic, if a notable fringe theory is primarily described by amateurs and self-published texts, verifiable and reliable criticism of the fringe theory need not be published in a peer-reviewed journal. For example, the Moon landing conspiracy theories article may include material from reliable websites, movies, television specials, and books that are not peer-reviewed. By parity of sources, critiques of that material can likewise be gleaned from reliable websites and books that are not peer-reviewed. Of course, for any viewpoint described in an article, only reliable sources should be used; Misplaced Pages's verifiability and biographies of living persons policies are not suspended simply because the topic is a fringe theory.
Quotations
Shortcut Further information: Misplaced Pages:Manual of Style § QuotationsThe accuracy of quoted material is paramount and the accuracy of quotations from living persons is especially sensitive. To ensure accuracy, the text of quoted material is best taken from (and cited to) the original source being quoted. If this is not possible, then the text may be taken from a reliable secondary source (ideally one that includes a citation to the original). No matter where you take the quoted text from, it is important to make clear the actual source of the text, as it appears in the article.
Partisan secondary sources should be viewed with suspicion as they may misquote or quote out of context. In such cases, look for neutral corroboration from another source.
Any analysis or interpretation of the quoted material, however, should rely on a secondary source (see Misplaced Pages:No original research).
Academic consensus
ShortcutA statement that all or most scientists or scholars hold a certain view requires reliable sourcing that directly says that all or most scientists or scholars hold that view. Otherwise, individual opinions should be identified as those of particular, named sources. Editors should avoid original research especially with regard to making blanket statements based on novel syntheses of disparate material. Stated simply, any statement in Misplaced Pages that academic consensus exists on a topic must be sourced rather than being based on the opinion or assessment of editors. Review articles, especially those printed in academic review journals that survey the literature, can help clarify academic consensus.
Statements of opinion
ShortcutSome sources may be considered reliable for statements as to their author's opinion, but not for statements asserted as fact. For example, an inline qualifier might say " says....". A prime example of this is opinion pieces in mainstream newspapers. When using them, it is best to clearly attribute the opinions in the text to the author and make it clear to the readers that they are reading an opinion (see also § Editorial and opinion commentary, above).
There is an important exception to sourcing statements of fact or opinion: Never use self-published books, zines, websites, webforums, blogs and tweets as a source for material about a living person, unless written or published by the subject of the biographical material. "Self-published blogs" in this context refers to personal and group blogs; see Misplaced Pages:Biographies of living persons § Reliable sources and Misplaced Pages:Biographies of living persons § Using the subject as a self-published source.
The exception for statements ABOUTSELF is covered at Misplaced Pages:Verifiability § Self-published or questionable sources as sources on themselves.
Breaking news
Shortcut Further information: Misplaced Pages:Biographies of living persons § Avoid gossip and feedback loops See also: Misplaced Pages:Notability (events) § Breaking newsBreaking-news reports often contain serious inaccuracies. As an electronic publication, Misplaced Pages can and should be up to date, but Misplaced Pages is not a newspaper and it does not need to go into all details of a current event in real time. It is better to wait a day or two after an event before adding details to the encyclopedia, than to help spread potentially false rumors. This gives journalists time to collect more information and verify claims, and for investigative authorities to make official announcements. The On the Media Breaking News Consumer's Handbook contains several suggestions to avoid spreading unreliable and false information. These include: distrust anonymous sources, unconfirmed reports, and reports attributed to other news media; seek multiple independent sources which independently verify; seek verified eyewitness reports; and be wary of potential hoaxes. With mass shootings, remain skeptical of early reports of additional attackers, coordinated plans, and bomb threats.
When editing a current-event article, keep in mind the tendency towards recentism bias. Claims sourced to initial news reports should be immediately replaced with better-researched and verified sources as soon as such articles are published, especially if original reports contained inaccuracies. All breaking news stories, without exception, are primary sources, and must be treated with caution: see Misplaced Pages:No original research § Primary, secondary and tertiary sources, Misplaced Pages:Identifying and using primary sources § Examples of news reports as primary sources.
The {{current}}, {{recent death}}, or another current-event-related template may be added to the top of articles related to a breaking-news event to alert readers that some information in the article may be inaccurate and to draw attention to the need to add improved sources as they become available. These templates should not be used, however, to mark articles on subjects or persons in the news. If they were, hundreds of thousands of articles would have such a template, without any significant advantage (see also Misplaced Pages:No disclaimers in articles).
For health- and science-related breaking-news, Misplaced Pages has specific sourcing standards to prevent inaccuracies: see Misplaced Pages:Identifying reliable sources (medicine) § Respect secondary sources and Misplaced Pages:Reliable sources § Scholarship. On the Media cautions consumers to be wary of news reports describing early science and medical breakthroughs, especially those which do not interview independent experts (often solely based on unreliable press releases), to prefer reports which avoid hyperbolic language and describe both benefits and costs of a new treatment (all treatments have trade-offs), to be wary of disease mongering (exaggerating risks, symptoms, or anecdotes of a disease which leads to unnecessary worry, panic, or spending), and to be skeptical of treatments which are "awaiting FDA approval
" or in pre-clinical testing" as more than 90% of all treatments fail during these stages and, even if efficacious, may be 10 to 15 years or more from reaching the consumer market.
Headlines
ShortcutsNews headlines—including subheadlines—are not a reliable source. If the information is supported by the body of the source, then cite it from the body. Headlines are written to grab readers' attention quickly and briefly; they may be overstated or lack context, and sometimes contain exaggerations or sensationalized claims with the intention of attracting readers to an otherwise reliable article. They are often written by copy editors instead of the researchers and journalists who wrote the articles.
Deprecated sources
Shortcut Main page: Misplaced Pages:Deprecated sources See also: Misplaced Pages:Reliable sources/Perennial sources and Misplaced Pages:Spam blacklistA number of sources are deprecated on Misplaced Pages. That means they should not be used, unless there is a specific consensus to do so. Deprecation happens through a request for comment, usually at the reliable sources noticeboard. It is reserved for sources that have a substantial history of fabrication or other serious factual accuracy issues (e.g. promoting unfounded conspiracy theories), usually when there are large numbers of references to the source giving rise to concerns about the integrity of information in the encyclopedia.
A deprecated source should not be used to support factual claims. While there are exceptions for discussion of the source's own view on something, these are rarely appropriate outside articles on the source itself. In general articles, commentary on a deprecated source's opinion should be drawn from independent secondary sources. Including a claim or statement by a deprecated source that is not covered by reliable sources risks giving undue weight to a fringe view.
Some sources are blacklisted, and can not be used at all. Blacklisting is generally reserved for sources which are added abusively, such as state-sponsored fake news sites with a history of addition by troll farms. Specific blacklisted sources can be locally whitelisted; see Misplaced Pages:Blacklist for other details about blacklisting.

Notes
- Examples include The Creation Research Society Quarterly and Journal of Frontier Science (the latter uses blog comments as peer review). Archived 2019-04-20 at the Wayback Machine).
- Many submissions to these predatory journals will be by scholars that a) cannot get their theories published in legitimate journals, b) were looking to quickly publish something to boost their academic resumes, or c) were honestly looking for a legitimate peer-review process to validate new ideas, but were denied the feedback by fraudulent publishers.
- A variety of these incidents have been documented by Private Eye and others and discussed on Misplaced Pages, where incorrect details from articles added as vandalism or otherwise have appeared in newspapers
- Please keep in mind that any exceptional claim would require exceptional sources, and this is policy.
