In academic publishing, a retraction is the action by which a published paper in an academic journal is removed from the journal. A retraction may be initiated by the editors of a journal, or by the author(s) of the papers (or their institution). Retractions are typically accompanied by a retraction notice written by the editors or authors explaining the reason for the retraction. [WIKI]

List of notable retractions [WIKI]

Retraction for error
  • 2013 – Study on the Mediterranean diet published in New England Journal of Medicine and widely covered by media was retracted due to unreported non-random assignments. This was part of a larger effort verifying proper randomization in thousands of studies by anesthesiologist John Carlisle, who found problems in about 2% of those analyzed.[5]
  • 2012 – Séralini affair – Article suggesting reported an increase in tumors among rats fed genetically modified corn and the herbicide RoundUp retracted due to criticism of experimental design. According to the editor of the journal, a “more in-depth look at the raw data revealed that no definitive conclusions can be reached with this small sample size”.[11]
  • 2003 Retracted Science article on ecstasy. See Retracted article on neurotoxicity of ecstasy.
  • Frank Cameron Jackson, supporter of the theory of epiphenomenalism, retracted his position due to an error in reasoning.[12]

Retraction for fraud or misconduct

  • 2021 An article studying open source community by Qiushi Wu and Kangjie Lu at University of Minnesota was withdrawn after Linux Foundation found out that researchers submitted patches for Linux kernel with intentional bugs without obtaining appropriate consent.[13][14]
  • 2020 On January 8 2020, a paper written by Dalmeet Singh Chawla in Science about the Russian journals retracted more than 800 articles in the first results of a large-scale investigation conducted by the Russian Academy of Sciences (RAS) following claims of unethical publications.[15]
  • 2017 5 articles by Brian Wansink at Cornell University came under scrutiny in the field of consumer behavior and marketing research after peers pointed out inconsistencies in data in papers after Wansink had written a blog post about asking a graduate student to “salvage” conclusions. Cornell University has since investigated the issues and in 2018 he was found by a University investigatory committee to have committed academic misconduct and resigned.[16][17][18] Wansink has since had 18 of his research papers retracted as similar issues were found in other publications.[19][20][21]
  • 2014 An article by Haruko Obokata et al. on STAP cells, a method of inducing a cell to become a stem cell, was proven to be falsified. Originally published in Nature, it was retracted later that year. It generated much controversy, and after an institutional investigation, one of the authors committed suicide.[22][23]
  • 2011 Retraction: Enhanced Inhibition of Tumour Growth and Metastasis, and Induction of Antitumour Immunity by IL-2-IgG2b Fusion Protein. Scandinavian Journal of Immunology, 73: 266. by Budagian V, Nanni P, Lollini PL, Musiani P, Di Carlo E, Bulanova E, Paus R, Bulfone-Paus S. 2002*[24]
  • 2011 Anil Potti, formerly a cancer researcher at Duke University. Eight journal articles authored by Anil Potti and others that describe genomic signatures of cancer prognosis and predictors of response to cancer treatment were retracted in 2011 and 2012. The retraction notices generally state that the results of the analyses described in the articles could not be reproduced. In November 2015, the Office of Research Integrity (ORI) found that Potti had engaged in research misconduct[25]
  • 2010 A 1998 paper by Andrew Wakefield proposing that the MMR vaccine might cause autism, which was responsible for the MMR vaccine controversy, was retracted because “the claims in the original paper that children were “consecutively referred” and that investigations were “approved” by the local ethics committee have been proven to be false.”[26]
  • 2009 Numerous papers written by Scott Reuben from 1996 to 2009 were retracted after it was discovered he never actually conducted any of the trials he claimed to have run.
  • 2007 Retraction of several articles written by social psychologist Jennifer Lerner and colleagues from journals including Personality and Social Psychology Bulletin and Biological Psychiatry.[27]
  • 2006 Retraction of Patient-specific embryonic stem cells derived from human SCNT blastocysts. written by Hwang Woo-Suk. Fabrications in the field of stem cell research led to ‘indictment on embezzlement and bioethics law violations linked to faked stem cell research’.
  • 2003 Numerous articles with questionable data from physicist Jan Hendrik Schön from many journals including both Science and Nature are retracted.
  • 2002 Retraction of announced discovery of elements 116 and 118. See Livermorium, Victor Ninov.
  • 1991 Thereza Imanishi-Kari, who worked with David Baltimore, published a 1986 article in the journal Cell. Margot O’Toole, a postdoctoral researcher for Imanishi-Kari publicized Imanishi-Kari’s scientific misconduct. After a major investigation, Baltimore was finally forced to issue a retraction in 1991 when the National Institutes of Health concluded that data in the 1986 Imanishi-Kari article had been falsified. In 1996, an expert panel appointed by the federal government cleared Imanishi-Kari of misconduct, finding no evidence of scientific fraud.
  • 1982 John Darsee. Fabricated results in the Cardiac Research Laboratory of Eugene Braunwald at Harvard in the early 1980s. Initially thought to be brilliant by his boss. He was caught out by fellow researchers in the same laboratory.

Retraction for ethical violations

  • 2019 An article by Wendy Rogers (Macquarie University, Australia) and colleagues on BMJ Open called for the mass retraction of more than 400 scientific papers on organ transplantation, amid fears the organs were obtained unethically from Chinese prisoners.[28] Wendy Rogers said the journals, researchers and clinicians who used these studies were complicit in these barbaric methods of organ trafficking. According to the study, the transplant research community has failed to live up to the ethical standards for using organs from death row inmates that are still being published. These widespread unethical violations in research will cause many unpredictable consequences for science.[29] In 2019, PLOS ONE also retracted 21 articles related to this incident.[30][31]
  • 2017 Journal Liver International retracted a scientific article by Chinese study of liver transplantation because 564 livers grafted in the course of the research over 4 years couldn’t be traced. The experts pointed out that a hospital could not have so many freely donated livers for transplantation compared with the small number of donors in China at the time.[32]

Retraction over data provenance

  • 2020 On 22 May 2020, during the COVID-19 pandemic, an article was published in The Lancet, claiming to find evidence, based on a database of 96032 COVID-19 patients, that hydroxychloroquine and chloroquine increase the chance of patients dying in hospital and increase the chance of ventricular arrhythmia.[33] Medical researchers and newspapers expressed suspicions about the validity of the data, provided by Surgisphere, founded by one of the authors of the study.[34] The article was formally retracted by 4 June 2020, on request by the lead author Mandeep Mehra.[35][33]

Retraction over public relations issues

  • 2016 On March 4, 2016, an article in PLOS ONE about the functioning of the human hand[36] was retracted due to outrage on social media over a reference to “Creator” inside the paper (#CreatorGate).[37]
  • 1896 Jose Rizal was said to have issued a letter of retraction regarding his novels and other published articles against the Roman Catholic Church, see José Rizal: Retraction controversy.
