== Basic definitions and urgency of dealing with misconduct ==

Various research ethics bodies provide definitions of scientific misconduct. For example, the U.S. Office of Research Integrity (ORI) defines research misconduct to include (any of) fabrication, falsification, and plagiarism.<ref>{{cite web |title=42 CFR § 93.103 – Research misconduct |url=https://www.ecfr.gov/current/title-42/chapter-I/subchapter-D/part-93/subpart-A/section-93.103 |website=Electronic Code of Federal Regulations (eCFR) |publisher=U.S. Government Publishing Office |access-date=21 February 2026 }}</ref><ref>{{cite web |title=Definition of Research Misconduct |url=https://ori.hhs.gov/definition-misconduct |website=Office of Research Integrity |publisher=U.S. Department of Health and Human Services |access-date=21 February 2026 }}</ref>

Three percent of the 3,475 research institutions that report to the US Department of Health and Human Services' Office of Research Integrity (ORI) indicate some form of scientific misconduct.<ref>{{Cite book|last1=Singh|first1=Dr. Yatendra Kumar|url=https://books.google.com/books?id=R0U1EAAAQBAJ&pg=PA90|title=Introduction of Research Methods and Publication Ethics|last2=Kumar Dubey|first2=Bipin|publisher=Friends Publications (India)|year=2021|isbn=978-93-90649-38-9|location=New Delhi|page=90}}</ref> However the ORI will only investigate allegations of impropriety where research was funded by federal grants.

==Forms == The U.S. National Science Foundation defines three types of research misconduct: fabrication, falsification, and plagiarism.<ref>{{cite web |url=https://www.nsf.gov/oig/session.pdf |title=New Research Misconduct Policies|publisher=NSF |access-date=2013-03-01 |archive-url=https://web.archive.org/web/20120910021419/https://www.nsf.gov/oig/session.pdf |archive-date=2012-09-10 }}</ref><ref>{{Cite web |title=2005 CFR Title 45, Volume 3 |url=http://www.access.gpo.gov/nara/cfr/waisidx_07/45cfr689_07.html |archive-url=https://web.archive.org/web/20120217204516/http://www.access.gpo.gov/nara/cfr/waisidx_07/45cfr689_07.html |archive-date=2012-02-17 |access-date=2025-06-27 |website=www.access.gpo.gov |url-status=live }}</ref> * '''Fabrication''' is making up results and recording or reporting them. This is sometimes referred to as "drylabbing".<ref name=Shapiro1992>{{Cite journal | last = Shapiro | first = M.F. | year = 1992 | title = Data audit by a regulatory agency: Its effect and implication for others | journal = Accountability in Research | volume = 2 | issue = 3 | pages = 219–229 | doi = 10.1080/08989629208573818 | pmid = 11653981}}</ref> A more minor form of fabrication is where references are included to give arguments the appearance of widespread acceptance, but are actually fake, or do not support the argument.<ref>Emmeche, slide 5</ref> * '''Falsification''' is manipulating research materials, equipment, or processes or changing or omitting data or results such that the research is not accurately represented in the research record. * '''Plagiarism''' is the appropriation of another person's ideas, processes, results, or words without giving appropriate credit. One form is the appropriation of the ideas and results of others, and publishing as to make it appear the author had performed all the work under which the data was obtained. There are recognized subsets of plagiarism: ** '''Citation plagiarism''' involves failure to credit relevant prior work and can, in some cases, be considered research misconduct when done intentionally to misrepresent priority or originality. This is also known as, "citation amnesia", the "disregard syndrome" and "bibliographic negligence".<ref>{{cite journal |first=Eugene |last=Garfield |url=http://www.garfield.library.upenn.edu/papers/demandcitationvigilance012102.html |title=Demand Citation Vigilance |journal=The Scientist |volume=16 |issue=2 |page=6 |date=January 21, 2002 |access-date=2009-07-30 |archive-date=2011-07-09 |archive-url=https://web.archive.org/web/20110709062039/http://www.garfield.library.upenn.edu/papers/demandcitationvigilance012102.html |url-status=dead }}</ref> Arguably, this is the most common type of scientific misconduct. Sometimes it is difficult to guess whether authors intentionally ignored a highly relevant cite or lacked knowledge of the prior work. Discovery credit can also be inadvertently reassigned from the original discoverer to a better-known researcher. This is a special case of the Matthew effect.<ref>Emmeche, slide 3, who refers to the phenomenon as Dulbecco's law.</ref> ** '''Plagiarism-fabrication''' is the act of mislabeling an unrelated figure from an unrelated publication and reproducing it exactly in a new publication, claiming that it represents new data. ** '''Self-plagiarism''' or multiple publication of the same content with different titles or in different journals is sometimes also considered misconduct; scientific journals explicitly ask authors not to do this. This practice, often called ‘salami publication,’ refers to dividing one study into multiple smaller publications and is generally discouraged by journals and research integrity guidelines. According to some editors, this includes publishing the same article in a different language if the same research as multiple publications is counted as separate research.<ref>{{cite web|url=http://www.wame.org/resources/publication-ethics-policies-for-medical-journals#orig|title=Publication Ethics Policies for Medical Journals|publisher=The World Association of Medical Editors|access-date=2009-07-30|archive-url=https://web.archive.org/web/20090731131343/http://www.wame.org/resources/publication-ethics-policies-for-medical-journals/#orig|archive-date=2009-07-31}}</ref>

Other types of research misconduct by authors are also recognized: * '''Unmerited authorship''' is the practice of giving authorship credit to someone improperly.<ref>{{Cite journal |last1=Ren |first1=Xiaopeng |last2=Su |first2=Hong |last3=Lu |first3=Kewen |last4=Dong |first4=Xiawei |last5=Ouyang |first5=Zhengzheng |last6=Talhelm |first6=Thomas |date=2016-12-27 |title=Culture and Unmerited Authorship Credit: Who Wants It and Why? |journal=Frontiers in Psychology |language=English |volume=7 |page=2017 |doi=10.3389/fpsyg.2016.02017 |pmid=28082940 |doi-access=free |issn=1664-1078|pmc=5186795 }}</ref><ref name=":0">{{Cite journal |last1=Marušić |first1=Ana |last2=Bošnjak |first2=Lana |last3=Jerončić |first3=Ana |date=2011-09-08 |title=A Systematic Review of Research on the Meaning, Ethics and Practices of Authorship across Scholarly Disciplines |journal=PLOS ONE |language=en |volume=6 |issue=9 |article-number=e23477 |doi=10.1371/journal.pone.0023477 |doi-access=free |issn=1932-6203 |pmc=3169533 |pmid=21931600 |bibcode=2011PLoSO...623477M }}</ref> Ghostwriting describes when someone other than the named author(s) makes a major contribution to the research.

Misconduct during scholarly peer review process: * A reviewer or editor with a conflict of interest can coerce the author to cite the reviewer's publications prior to recommending publication. This can inflate the perceived citation impact of a researcher's work and their reputation in the scientific community,<ref>{{cite journal |last1=Wren |first1=Jonathan D |last2=Valencia |first2=Alfonso |last3=Kelso |first3=Janet |title=Reviewer-coerced citation: case report, update on journal policy and suggestions for future prevention |journal=Bioinformatics |date=15 September 2019 |volume=35 |issue=18 |pages=3217–3218 |doi=10.1093/bioinformatics/btz071 |pmid=30698640 |pmc=6748764 }}</ref> similar to excessive self-citation. * Suggesting fake peer reviewers can happen when journals invite authors to recommend a list of suitable peer reviewers, along with their contact information. In some cases, authors have recommended a "reviewer" for whom they provide a fake email address that in fact belongs to the author. If the editor follows the author's reviewer recommendation, the author can then write their own review.<ref>{{cite journal | last1=McLellan | first1=Timothy | title=Asian Tricks and Research Misconduct: From Orientalism and Occidentalism to Solidarity against Audit Cultures | journal=East Asian Science, Technology and Society| date=2025 | pages=1–21 | doi=10.1080/18752160.2025.2482324 | doi-access=free }}</ref><ref>Biagioli, Mario. 2016.

=== Photo manipulation ===  Manipulation of images constitutes a form of research misconduct that some journals actively screen for because it can be detected through image analysis tools. In 2006, the ''Journal of Cell Biology'' gained publicity for instituting tests to detect photo manipulation in papers that were being considered for publication.<ref>{{cite news| url=https://www.nytimes.com/2006/01/24/science/24frau.html?_r=1 | work=New York Times | title=It May Look Authentic; Here's How to Tell It Isn't | author=Nicholas Wade | date=2006-01-24 | access-date=2010-04-01| author-link=Nicholas Wade }}</ref> This was in response to the increased usage of programs such as Adobe Photoshop by scientists, which facilitate photo manipulation. Since then more publishers, including the Nature Publishing Group, have instituted similar tests and require authors to minimize and specify the extent of photo manipulation when a manuscript is submitted for publication. However, there is little evidence to indicate that such tests are applied rigorously. One ''Nature'' paper published in 2009<ref name="Kato" /> has subsequently been reported to contain around 20 separate instances<ref>{{cite web|author=11jigen |url=http://katolab-imagefraud.blogspot.co.uk/2012/01/dna-demethylation-in-hormone-induced.html |title=Shigeaki Kato (the University of Tokyo): DNA demethylation in hormone-induced transcriptional derepression |website=Katolab-imagefraud.blogspot.co.uk |date=2012-01-15 |access-date=2013-08-04}}</ref> of image fraud.

Although the type of manipulation that is allowed can depend greatly on the type of experiment that is presented and also differ from one journal to another, in general the following manipulations are not allowed:<ref>{{Cite web |title=Restrictions of Image Manipulation |url=https://www.amed.go.jp/content/000048624.pdf |access-date=April 22, 2024 |website=AMED}}</ref><ref>{{Cite web |title=Editorial Policies |url=https://rupress.org/jcb/pages/editorial-policies#data-integrity |access-date=2024-04-22 |website=rupress.org}}</ref> * splicing together different images to represent a single experiment * changing brightness and contrast of only a part of the image * any change that conceals information, even when it is considered to be non-specific, which includes: ** changing brightness and contrast to leave only the most intense signal ** using clone tools to hide information * showing only a very small part of the photograph so that additional information is not visible

Image manipulations are typically done on visually repetitive images such as those of blots and microscope images.<ref>{{Cite web|last=Ritchie|first=Stuart|date=2021-07-02|title=Why Are Gamers So Much Better Than Scientists at Catching Fraud?|url=https://www.theatlantic.com/science/archive/2021/07/gamers-are-better-scientists-catching-fraud/619324/|access-date=2021-07-19|website=The Atlantic|language=en}}</ref>

==Motivations== According to David Goodstein of Caltech, there are multiple motivators for scientists to commit misconduct, which are briefly summarised here.<ref>{{cite journal |last1=Goodstein |first1=David |date=January–February 2002 |title=Scientific misconduct |journal=Academe |volume=88 |issue=1 |pages=28–31 |doi=10.2307/40252116 |jstor=40252116 |url=http://www.aaup.org/AAUP/pubsres/academe/2002/JF/Feat/good.htm|url-access=subscription }}</ref> Research on the motivations for scientific misconduct often cites publication pressure and career incentives as contributing factors.

* Career pressure – Science is a very strongly career-driven discipline. Scientists depend on their record of achievement to receive ongoing support and funding, and a good reputation relies largely on the publication of high-profile scientific papers. Hence, there is a strong imperative to "publish or perish". This pressure is stronger in some research settings than others, contributing to the increased prevalence of misconduct in some parts of the world than others.<ref name="auto" /> This may motivate desperate (or fame-hungry) scientists to fabricate results. * Ease of fabrication – In many scientific fields, results are often difficult to reproduce accurately, being obscured by noise, artifacts, and other extraneous data. That means that even if a scientist does falsify data, they may expect to get away with it – or at least claim innocence if their results conflict with others in the same field. There are few strongly backed systems to investigate possible violations, attempt to press charges, or punish deliberate misconduct. It is relatively easy to cheat although difficult to know exactly how many scientists fabricate data.<ref>{{Cite journal | last1 = Fanelli | first1 = D. | editor1-last = Tregenza | editor1-first = Tom | title = How Many Scientists Fabricate and Falsify Research?

Corporations can pay experts to support products directly or indirectly via conferences. Psychologists can make money by repeatedly acting as an expert witness in custody proceedings for the same law firms. * Political bias among scientists can motivate reduced scientific integrity and academic bias.<ref name="y499">{{cite journal | last1=Duarte | first1=José L. | last2=Crawford | first2=Jarret T. | last3=Stern | first3=Charlotta | last4=Haidt | first4=Jonathan | last5=Jussim | first5=Lee | last6=Tetlock | first6=Philip E. | title=Political diversity will improve social psychological science | journal=Behavioral and Brain Sciences | volume=38 | date=2015 | issn=0140-525X | doi=10.1017/S0140525X14000430 | url=https://www.cambridge.org/core/product/identifier/S0140525X14000430/type/journal_article | access-date=2026-02-24 | page=| url-access=subscription }}</ref>

== Roles == === Scientists === All authors of a scientific publication are expected to have made reasonable attempts to check findings submitted to academic journals for publication.

Simultaneous submission of scientific findings to more than one journal or duplicate publication of findings is usually regarded as misconduct, under what is known as the Ingelfinger rule, named after the editor of The New England Journal of Medicine 1967–1977, Franz Ingelfinger.<ref>{{cite journal |last1=Toy |first1=Jennifer |year=2002 |title=The Ingelfinger Rule: Franz Ingelfinger at The New England Journal of Medicine 1967–77 |url=http://cseditors.wpengine.com/wp-content/uploads/v25n6p195-198.pdf |journal=Science Editor |volume=25 |issue=6 |pages=195–198 }}{{Dead link|date=October 2025 |bot=InternetArchiveBot }}</ref>

Guest authorship (where there is stated authorship in the absence of involvement, also known as gift authorship) and ghost authorship (where the real author is not listed as an author) are commonly regarded as forms of research misconduct. In some cases coauthors of faked research have been accused of inappropriate behavior or research misconduct for failing to verify reports authored by others or by a commercial sponsor. Examples include the case of Gerald Schatten who co-authored with Hwang Woo-Suk, the case of Professor Geoffrey Chamberlain named as guest author of papers fabricated by Malcolm Pearce,<ref name="BMJ1995">{{Cite journal |title=Lessons from the Pearce affair: handling scientific fraud |journal=BMJ |date= June 17, 1995 |volume=310 |issue=6994 |pages=1547–148 |doi=10.1136/bmj.310.6994.1547 |pmid=7787632 |pmc=2549935 | last1 = Lock | first1 = S}} {{registration required}}</ref> (Chamberlain was exonerated from collusion in Pearce's deception)<ref name="Independent Committee of Inquiry into the publication of articles in the British Journal of Obstetrics and Gynaecology">{{cite web |title=Independent Committee of Inquiry into the publication of articles in the British Journal of Obstetrics and Gynaecology (1994–1995) |url=http://www.aim25.ac.uk/cats/7/4972.htm |access-date=2011-08-26}}</ref> – and the coauthors with Jan Hendrik Schön at Bell Laboratories.

Authors are expected to keep all study data for later examination even after publication. The failure to keep data may be regarded as misconduct. Some scientific journals require that authors provide information to allow readers to determine whether the authors might have commercial or non-commercial conflicts of interest. Authors are also commonly required to provide information about ethical aspects of research, particularly where research involves human or animal participants or use of biological material. Provision of incorrect information to journals may be regarded as misconduct. Financial pressures on universities have encouraged this type of misconduct. The majority of recent cases of alleged misconduct involving undisclosed conflicts of interest or failure of the authors to have seen scientific data involve collaborative research between scientists and biotechnology companies.<ref name="the-scientist.com"/><ref>{{cite web|last=Dickerson |first=John |url=http://www.slate.com/id/2133061/ |title=Did a British university sell out to P&G? |website=Slate |date= 2005-12-22|access-date=2013-08-04}}</ref>

=== Research institution === In general, defining whether an individual is guilty of misconduct requires a detailed investigation by the individual's employing academic institution. Such investigations require detailed and rigorous processes and can be extremely costly. Furthermore, the more senior the individual under suspicion, the more likely it is that conflicts of interest will compromise the investigation. In many countries (with the notable exception of the United States) acquisition of funds on the basis of fraudulent data is not a legal offence and there is consequently no regulator to oversee investigations into alleged research misconduct. Universities therefore have few incentives to investigate allegations in a robust manner, or act on the findings of such investigations if they vindicate the allegation.

Well publicised cases illustrate the potential role that senior academics in research institutions play in concealing scientific misconduct. A King's College (London) internal investigation showed research findings from one of their researchers to be 'at best unreliable, and in many cases spurious'<ref>{{cite journal | author = Wilmshurst P | year = 2002| title = Institutional corruption in medicine (2002) | journal = British Medical Journal | volume = 325 | issue = 7374| pages = 1232–1235 | doi=10.1136/bmj.325.7374.1232| pmid = 12446544| pmc = 1124696}}</ref> but the college took no action, such as retracting relevant published research or preventing further episodes from occurring.

In a more recent case<ref>{{cite journal |last=Jayaraman |first=K. S. |title=Indian scientists battle journal retraction | journal=Nature |volume=447 | issue=7146 |date=June 14, 2007 | doi = 10.1038/447764a | page=764 | pmid=17568715|bibcode=2007Natur.447..764J |doi-access=free }}</ref> an internal investigation at the National Centre for Cell Science (NCCS), Pune determined that there was evidence of misconduct by Gopal Kundu, but an external committee was then organised which dismissed the allegation, and the NCCS issued a memorandum exonerating the authors of all charges of misconduct. Undeterred by the NCCS exoneration, the relevant journal (''Journal of Biological Chemistry'') withdrew the paper based on its own analysis.

=== Scientific peers === Some academics believe that scientific colleagues who suspect scientific misconduct should take informal action themselves, or report their concerns.<ref>See {{cite journal |author1=Gerald Koocher |author2=Patricia Keith-Spiegel |name-list-style=amp |date=22 July 2010| title= Peers Nip Misconduct in the Bud | doi = 10.1038/466438a | bibcode=2010Natur.466..438K | volume=466 |issue=7305 | journal=Nature | pages=438–440 | pmid=20651674|s2cid=4396687 }} and (with Joan Sieber) Responding to Research Wrongdoing: A User Friendly Guide, July 2010.</ref> This question is of great importance since much research suggests that it is very difficult for people to act or come forward when they see unacceptable behavior, unless they have help from their organizations.

=== Journals === Journals are responsible for safeguarding the research record and hence have a critical role in dealing with suspected misconduct. This is recognised by the Committee on Publication Ethics (COPE), which has issued clear guidelines<ref>[http://www.publicationethics.org/files/retraction%20guidelines.pdf Retraction Guidelines] {{Webarchive|url=https://web.archive.org/web/20200326074637/http://publicationethics.org/files/retraction%20guidelines.pdf |date=2020-03-26 }} (PDF)</ref> on the form (e.g. retraction) that concerns over the research record should take. * The COPE guidelines state that journal editors should consider retracting a publication if they have clear evidence that the findings are unreliable, either as a result of misconduct (e.g. data fabrication) or honest error (e.g. miscalculation or experimental error). Retraction is also appropriate in cases of redundant publication, plagiarism and unethical research. * Journal editors should consider issuing an expression of concern if they receive inconclusive evidence of research or publication misconduct by the authors, there is evidence that the findings are unreliable but the authors' institution will not investigate the case, they believe that an investigation into alleged misconduct related to the publication either has not been, or would not be, fair and impartial or conclusive, or an investigation is underway but a judgement will not be available for a considerable time. * Journal editors should consider issuing a correction if a small portion of an otherwise reliable publication proves to be misleading (especially because of honest error), or the author / contributor list is incorrect (i.e. a deserving author has been omitted or somebody who does not meet authorship criteria has been included).

Evidence emerged in 2012 that journals learning of cases where there is strong evidence of possible misconduct, with issues potentially affecting a large portion of the findings, frequently fail to issue an expression of concern or correspond with the host institution so that an investigation can be undertaken.

The cases of Joachim Boldt and Yoshitaka Fujii<ref>{{cite web|url=http://retractionwatch.wordpress.com/2012/03/07/major-fraud-probe-of-japanese-anesthesiologist-yoshitaka-fujii-may-challenge-retraction-record/ |title=Major fraud probe of Japanese anesthesiologist Yoshitaka Fujii may challenge retraction record |website=RetractionWatch |date= 2012-03-08|access-date=2013-08-04}}</ref> in anaesthesiology focussed attention on the role that journals play in perpetuating scientific fraud as well as how they can deal with it. In the Boldt case, the editors-in-chief of 18 specialist journals (generally anesthesia and intensive care) made a joint statement regarding 88 published clinical trials conducted without Ethics Committee approval. In the Fujii case, involving nearly 200 papers, the journal ''Anesthesia & Analgesia'', which published 24 of Fujii's papers, has accepted that its handling of the issue was inadequate. Following publication of a letter to the editor from Kranke and colleagues in April 2000,<ref>{{Cite journal | last1 = Kranke | first1 = P. | last2 = Apfel | first2 = C.

''Anesthesia & Analgesia'' went on to publish 11 additional manuscripts by Dr. Fujii following the 2000 allegations of research fraud, with Editor Steven Shafer stating<ref>[http://www.aaeditor.org/FujiiStatementOfConcern.pdf Fujii Statement of Concern] {{Webarchive|url=https://web.archive.org/web/20160304002429/http://www.aaeditor.org/FujiiStatementOfConcern.pdf |date=2016-03-04 }} (PDF)</ref> in March 2012 that subsequent submissions to the journal by Dr. Fujii should not have been published without first vetting the allegations of fraud. In April 2012 Shafer led a group of editors to write a joint statement,<ref>[http://www.aaeditor.org/Fujii_Joint_EIC_Stmt.pdf Fujii Join EIC Statement] {{Webarchive|url=https://web.archive.org/web/20160304042852/http://www.aaeditor.org/Fujii_Joint_EIC_Stmt.pdf |date=2016-03-04 }} (PDF)</ref> in the form of an ultimatum made available to the public, to a large number of academic institutions where Fujii had been employed, offering these institutions the chance to attest to the integrity of the bulk of the allegedly fraudulent papers.

===Research paper mills=== In August 2025, a study published in the ''Proceedings of the National Academy of Sciences'' uncovered evidence of large-scale scientific publishing fraud involving networks of editors, authors, and research paper mills.<ref>{{cite journal |last1=Richardson|first1=Reese A.K.|last2=Hong|first2=Spencer S.|last3=Byrne|first3=Jennifer A.|last4=Stoeger|first4=Thomas|last5=Amaral|first5=Luís A.

== Consequences == === Consequences for scientific knowledge === The consequences of scientific fraud vary based on the severity of the fraud, the level of notice it receives, and how long it goes undetected. For cases of fabricated evidence, the consequences can be wide-ranging, with others working to confirm (or refute) the false finding, or with research agendas being distorted to address the fraudulent evidence. The Piltdown Man fraud is a case in point: The significance of the bona-fide fossils that were being found was muted for decades because they disagreed with Piltdown Man and the preconceived notions that those faked fossils supported. In addition, the prominent paleontologist Arthur Smith Woodward spent time at Piltdown each year until he died, trying to find more Piltdown Man remains. The misdirection of resources kept others from taking the real fossils more seriously and delayed the reaching of a correct understanding of human evolution. (The Taung Child, which should have been the death knell for the view that the human brain evolved first, was instead treated very critically because of its disagreement with the Piltdown Man evidence.)

In the case of Prof. Don Poldermans, the misconduct occurred in reports of trials of treatment to prevent death and myocardial infarction in patients undergoing operations.<ref>{{cite journal|last1=Vogel|first1=G.|title=Suspect Drug Research Blamed for Massive Death Toll|journal=Science|date=30 January 2014|volume=343|issue=6170|pages=473–474|doi=10.1126/science.343.6170.473|ref=Science2014|pmid=24482457|bibcode=2014Sci...343..473V}}</ref> The trial reports were relied upon to issue guidelines that applied for many years across North America and Europe.<ref>{{cite journal|last1=Cole|first1=G.

In the case of Dr Alfred Steinschneider, two decades and tens of millions of research dollars were lost trying to find the elusive link between infant sleep apnea, which Steinschneider said he had observed and recorded in his laboratory, and sudden infant death syndrome (SIDS), of which he stated it was a precursor. The cover was blown in 1994, 22 years after Steinschneider's 1972 ''Pediatrics'' paper claiming such an association,<ref name="aappublications646">{{cite journal |author=Steinschneider A |title=Prolonged apnea and the sudden infant death syndrome: clinical and laboratory observations |journal=Pediatrics |volume=50 |issue=4 |pages=646–654 |date=October 1972 |doi=10.1542/peds.50.4.646 |pmid=4342142 |s2cid=8561269 |url=http://pediatrics.aappublications.org/cgi/content/abstract/50/4/646|url-access=subscription }}</ref> when Waneta Hoyt, the mother of the patients in the paper, was arrested, indicted and convicted on five counts of second-degree murder for the smothering deaths of her five children.<ref name="amazon1997">{{cite book |author1=Talan, Jamie |author2=Firstman, Richard |title=The death of innocents |publisher=Bantam Books |location=New York |year=1997 |isbn=978-0-553-10013-6 }}</ref> While that in itself was bad enough, the paper, presumably written as an attempt to save infants' lives, ironically was ultimately used as a defense by parents suspected in multiple deaths of their own children in cases of Münchausen syndrome by proxy.

=== Regulatory violations and consequences === [https://www.nrc.gov/reading-rm/doc-collections/cfr/part050/part050-0005.html Title 10 Code of Federal Regulation (CFR) Part 50.5, Deliberate Misconduct] of the U.S. Nuclear Regulatory Commission (NRC) regulations, addresses the prohibition of certain activities by individual involved in NRC-licensed activities. 10 CFR 50.5 is designed to ensure the safety and integrity of nuclear operations. [https://www.nrc.gov/reading-rm/doc-collections/cfr/part050/part050-0009.html 10 CFR Part 50.9, Completeness and Accuracy of Information], focuses on the requirements for providing information and data to the NRC. The intent of 10 CFR 50.5 is to deter and penalize intentional wrongdoing (i.e., violations). 10 CFR 50.9 is crucial in maintaining transparency and reliability in the nuclear industry, which effectively emphasizes honesty and integrity in maintaining the safety and security of nuclear operations. Providing false or misleading information or data to the NRC is therefore a violation of 10 CFR 50.9.

Violation of any of these rules can lead to severe penalties, including termination, fines and criminal prosecution. It can also result in the revocation of licenses or certifications, thereby barring individuals or entities from participating in any NRC-licensed activities in the future.

===Consequences for those who report misconduct=== The potentially severe consequences for individuals who are found to have engaged in misconduct also reflect on the institutions that host or employ them and also on the participants in any peer review process that has allowed the publication of questionable research. This means that a range of actors in any case may have a motivation to suppress any evidence or suggestion of misconduct. Persons who expose such cases, commonly called whistleblowers, find themselves open to retaliation by a number of different means.<ref name="BMJ1995"/> These negative consequences for exposers of misconduct have driven the development of whistle blowers charters – designed to protect those who raise concerns.

== Incidence == The vast majority of cases of scientific misconduct may not be reported. The number of article retractions in 2022 was nearly 5,500, but Ivan Oransky and Adam Marcus, co-founders of ''Retraction Watch'', estimate that at least 100,000 retractions should occur every year, with only about one in five being due to "honest error".<ref>{{cite news |title=There's far more scientific fraud than anyone wants to admit |first1=Ivan |last1=Oransky |first2= Adam |last2=Marcus |author-link1=Ivan Oransky |author-link2=Adam Marcus (science journalist) |url=https://www.theguardian.com/commentisfree/2023/aug/09/scientific-misconduct-retraction-watch |newspaper=The Guardian |date=August 9, 2023 |access-date=August 12, 2023}}</ref> One survey of researchers found that 29% of researchers reported misusing authorship at least once during their career, such as giving "gift authorship" to people who were not involved in the research.<ref name=":0" />

A 2025 study by Northwestern university after reviewing aggregated data on the lists of deindexed journals from literature aggregators such as Web of Science, Scopus, Medline, data from Retraction Watch and PubPeer found that while the total number of research publications double every 15 years, articles from suspected research paper mills double every 1.5 years while the number of retracted articles double every 3.3 years and number of articles with PubPeer comments double every 3.6 years.<ref name="Richardson 2025"/>

Recent work by Ilka Agricola and colleagues has for the first time systematically documented fraudulent practices in mathematical publishing and proposed concrete measures to address them. In "Fraudulent Publishing in the Mathematical Sciences," Agricola et al. analyze how predatory journals, paper mills, and citation cartels exploit bibliometric incentives, warning that unvetted "proofs" in low-quality outlets can mislead subsequent research.

== Proposed responses == ===Exposure === There are several tools available to aid in the detection of plagiarism and multiple publication within biomedical literature. One tool developed in 2006 by researchers in Dr. Harold Garner's laboratory at the University of Texas Southwestern Medical Center at Dallas is Déjà vu,<ref>{{cite web |url=http://dejavu.vbi.vt.edu/dejavu/ |title=Déjà vu: Medline duplicate publication database |website=dejavu.vbi.vt.edu |access-date=2013-08-04 |archive-date=2015-04-25 |archive-url=https://web.archive.org/web/20150425082932/http://dejavu.vbi.vt.edu/dejavu/ }}</ref> an open-access database containing several thousand instances of duplicate publication. All of the entries in the database were discovered through the use of text data mining algorithm eTBLAST, also created in Dr. Garner's laboratory. The creation of Déjà vu<ref>{{cite web |url=http://dejavu.vbi.vt.edu/dejavu |title=Deja vu: Medline duplicate publication database |website=dejavu.vbi.vt.edu |access-date=2013-08-04 |archive-url=https://web.archive.org/web/20140722061546/http://dejavu.vbi.vt.edu/dejavu/ |archive-date=2014-07-22 }}</ref> and the subsequent classification of several hundred articles contained therein have ignited much discussion in the scientific community concerning issues such as ethical behavior, journal standards, and intellectual copyright. Studies within this database have been published in journals such as ''Nature'' and ''Science'', among others.<ref>{{cite journal |author1=Errami M |author2=Garner HR |doi=10.1038/451397a |title=A tale of two citations |date=2008-01-23 |volume=451 |issue=7177 |journal=Nature |pages=397–399 |pmid=18216832|bibcode=2008Natur.451..397E |s2cid=4358525 |doi-access=free }}</ref><ref>{{cite journal |author1=Long TC |author2=Errami M |author3=George AC |author4=Sun Z |author5=Garner HR |doi=10.1126/science.1167408 |title=Scientific Integrity: Responding to Possible Plagiarism |journal=Science |date=2009-03-06 |volume=323 |issue=5919 |pages=1293–1294 |pmid=19265004|s2cid=28467385 }}</ref>

Other tools which may be used to detect fraudulent data include error analysis. Measurements generally have a small amount of error, and repeated measurements of the same item will generally result in slight differences in readings. These differences can be analyzed, and follow certain known mathematical and statistical properties. Should a set of data appear to be too faithful to the hypothesis, i.e., the amount of error that would normally be in such measurements does not appear, a conclusion can be drawn that the data may have been forged. Error analysis alone is typically not sufficient to prove that data have been falsified or fabricated, but it may provide the supporting evidence necessary to confirm suspicions of misconduct.

=== Data sharing === Kirby Lee and Lisa Bero suggest, "Although reviewing raw data can be difficult, time-consuming and expensive, having such a policy would hold authors more accountable for the accuracy of their data and potentially reduce scientific fraud or misconduct."<ref>{{cite journal | year = 2006 | title = Ethics: Increasing accountability | url = http://www.nature.com/nature/peerreview/debate/nature05007.html | journal = Nature | last1 = Lee | first1 = Kirby | doi = 10.1038/nature05007 | doi-broken-date = 2 July 2025 | archive-url = https://archive.today/20120912175551/http://www.nature.com/nature/peerreview/debate/nature05007.html | access-date = 2010-08-16 | archive-date = 2012-09-12 | url-access = subscription }}</ref>

=== Changing research valuation === Since 2012, the Declaration on Research Assessment (DORA), from San Francisco, gathered many institutions, publishers, and individuals committing to improving the metrics used to assess research and to stop focusing on the journal impact factor.<ref>{{Cite web |title=Read the Declaration |url=https://sfdora.org/read/ |access-date=2022-06-07 |website=DORA |language=en-US}}</ref>
