Scientific misconduct is the violation of the standard codes of scholarly conduct and ethical behavior in the publication of professional scientific research. A Lancet review on Handling of Scientific Misconduct in Scandinavian countries gave examples of policy definitions. In Denmark, scientific misconduct is defined as "intention[al] negligence leading to fabrication of the scientific message or a false credit or emphasis given to a scientist", and in Sweden as "intention[al] distortion of the research process by fabrication of data, text, hypothesis, or methods from another researcher's manuscript form or publication; or distortion of the research process in other ways."^[1][2]

A 2009 systematic review and meta-analysis of survey data found that about 2% of scientists admitted to falsifying, fabricating, or modifying data at least once.^[3]

Incidents should only be included in this list if the individuals or entities involved have their own Wikipedia articles, or in the absence of an article, where the misconduct incident is covered in multiple reliable sources.

A committee reviewing 212 papers published by Fujii over a span of 20 years found that 126 were entirely fabricated, with no scientific work done. Only 3 were found to be valid. He was also found to have forged the signatures of scientists he listed as co-authors without their knowledge.^[68][69][70] As of 2023, Fujii has had 182 of their research publications retracted, and 47 others have received an expression of concern.^[71]

• Many major trials of the drug ivermectin that claimed it could prevent COVID-19 were found to show signs of fraud and had "either obvious signs of fabrication or errors so critical they invalidate the study," according to one of the groups investigating the studies.^[77] For example, some studies were found to list patients who had never actually participated in the research, and others placed patients who were already statistically more likely to die in the placebo group while putting the healthier patients in the experimental group that received ivermectin.^[78][77] Studies that were found to contain legitimate research were generally inconclusive about the effects of ivermectin on COVID-19.^[78]
• He Jiankui (China), former associate professor with the Southern University of Science and Technology, was in 2019 sentenced to three years in prison and fined three million yuan (about US$430,000) for illegally carrying out human embryo gene-editing intended for reproduction.^[79] The case is called the He Jiankui affair.^[80][81]

• Annarosa Leri (US, Italy) and Piero Anversa (US, Italy), collaborators and former researchers at Harvard University, were found in a 2014 investigation to have "manipulated and falsified" data in their research on endogenous cardiac stem cells, and to have included "false scientific information" in grant applications; these events resulted in Partners HealthCare and Brigham and Women's Hospital paying a $10 million settlement to the US government, and pausing a clinical trial based on Anversa and Leri's work.^{[111][112][113]} In October 2018, following many failed replications of their work, Harvard University and Brigham and Women's Hospital called for the retraction of 31 publications from the Anversa/Leri research group.^[114] Anversa and Leri lost a lawsuit they brought against Harvard that claimed the 2014 investigation had damaged their reputations.^[115] As of 2024, Anversa and Leri have had 19 research publications retracted, 17 others have received an expression of concern, and 12 others have been corrected.^[116][117]

• Kenichiro Itami (Japan), Nagoya University professor, and other members of his laboratory committed scientific misconduct in the graphene nanoribbon fraud.^[215] As a result of that misconduct, in 2022 Itami and the other implicated lab members were banned from receiving research support from the Japan Society for the Promotion of Science for at least three years.^[216][217] As of 2023, Itami has had three of his research publications retracted, one other paper has received an expression of concern, and one other paper has been corrected.^[218].Itami was held responsible, and the Japan Science and Technology Agency (JST) and the Japan Society for the Promotion of Science (JSPS), which determine the allocation of government research funds, have stopped granting research funds as a penalty until the end of March 2025^[219] from the university. Despite this, RIKEN, which is funded mainly by research fees from the government, hired Itami and obtained about 50 million yen in research funding. He pioneered a loophole that allowed him to obtain research funding by belonging to a national research corporation even if his research funding from the government was suspended due to research misconduct. ^[220]
• The independent misconduct of two chemists at the William A. Hinton State Laboratory Institute in Massachusetts caused the drug lab to be shut down and tens of thousands of criminal convictions for drug possession to be overturned.

Sonja Farak admitted to stealing samples and using them to get high herself.^[221] The affairs were documented in the 2020 film How to Fix a Drug Scandal.

• Masaya Sawamura (Japan), science misconduct made a significant impact in the field of chemistry. Several of his academic papers were retracted due to concerns about manipulated or fabricated data. In 2022, the Chemistry group at Hokkaido University, where Sawamura is affiliated, retracted multiple papers, including one published in the journal Science in 2020. The retraction was attributed to the non-reproducibility of reported results and manipulation of nuclear magnetic resonance (NMR) spectra. Additionally, two papers by Sawamura's team, originally published in 2019 in the Journal of the American Chemical Society, were retracted due to the manipulation or fabrication of NMR spectra and HPLC charts.^[222][223]
• Bengü Sezen (US), a graduate student at Columbia University, was found to have falsified data in her research for over a decade by editing NMR data to fit her desired results. At least six of her research papers have been withdrawn and Columbia University has moved to revoke her Ph.D.^[224][225]

The paper "contains significant portions of original text" from three papers by others and was "copied with insufficient attribution (including appropriate references to the original author(s) and/or paper title) and without permission. Due to the nature of this violation, reasonable effort should be made to remove all past references to this paper, and future references should be made to the following article[sic]...."^[234]

• In 2016 the scientific publisher Springer Nature retracted 58 papers from seven journals, authored mostly by Iran-based researchers, because the papers showed evidence of authorship manipulation, peer-review manipulation, and/or plagiarism.^[317][318]
• Ohio University in 2006 alleged more than three dozen cases of plagiarism in master's degree theses dating back 20 years in its mechanical engineering department.^[319] A former faculty member involved in the plagiarism cases, Jay S. Gunasekera, was removed from his position as department chair, had his title of "distinguished professor" rescinded,^[320] and in 2011 settled a lawsuit he had brought against the university.^[321] Another former faculty member implicated in the plagiarism cases, Bhavin Mehta, in 2012 lost a defamation suit he had brought against the university.^[322]

• An investigation by the UK scientific journal Nature published on 8 January 2020, found that eight James Cook University (JCU) studies on the effect of climate change on coral reef fish, one of which was authored by the JCU educated discredited scientist Oona Lönnstedt, had a 100 percent replication failure and thus none of the findings of the original eight studies were found to be correct.^[326] The Swedish scientists Josefin Sundin and Fredrik Jutfelt were the first to report their suspicions to Uppsala University. Their informal investigation, and the proofs they collected, lead to the formal investigation.^[327] Concerns raised about a study Lönnstedt published while at JCU between 2010 and 2014 included an improbable number of lionfish claimed to have been used in this study, and images of 50 fish provided which appeared to include multiple images of some biological specimens, and two images that had been flipped making two fish appear to be four.^[328][329] Lönnstedt had also been found guilty of fabricating data underpinning a study at Uppsala University in Sweden following her departure from JCU in Queensland, Australia.^[330] The study was subsequently retracted.^[331]
