The perfect hacking of journal peer review or… The fastest way to become a Highly Cited Researcher

Since the beginning of the 21st century, the names of great fraudsters have spread beyond the academic arenas, each one bringing their biographies, their practices and the astonished tale of the discovery of their misdeeds. This starisation of fraudsters should neither hide the existence of famous cases in the past1, nor the multitude of ordinary misdemeanors and misconduct daily taking place in the academic world, which is hardly different from other professional circles in this respect. Nevetheless, they deserve a place in the Hall of Hame of academic fraudsters; so, before addressing the case of our new champion Kuo-Chen Chou, let’s review a few exemplary figures of this Hall of Fame, in alphabetical order.

Yoshitaka Fujii (2012): enduring Japanese anesthesiologist who owns is world record holder for the number of articles retracted (183). He spent his career inventing data and despite a statistical analysis published in 2000 showing how “too nice” his numbers were, he was not really worried until 10 years later.2

Woo-Suk Hwang (2006) : amazing Korean veterinarian and biologist, specialized in stem cells and producer of the first human clone, announced by a publication in Science. After being accused of forcing his technicians to donate their eggs for his research, investigations revealed the total absence of human cloning. A national glory in South Korea and an international star, his public downfall was so brutal that he made the cover of Time Magazine.

Jan-Hendrik Schön (2002): industrious German physicist, working at Bell Labs on the limits of matter and life, able to co-author in less than two years seven papers in Nature, eight in Science and six in Physic Review. All of course have since been retracted, and it seems that all his research, including his thesis, was based more on his desire to stick to the expectations of theory or those of his colleagues than on the empirical results he claimed to have achieved.3

Diederik Stapel (2011) : extraordinary Dutch psychologist, whose social experiments always proved the hypotheses made… since they were never carried out, but fabricated on paper and computer. Denounced by a whistleblower from his team and 58 retracted articles later, he was the object of a sensitive New York Times portrait . His own production became an object of psychology of deception as his colleagues found small differences in style between his genuine articles and the fake ones.

From transparent peer review
to citation manipulation

These eminent members of the Hall of Fame, all men – women are an extremely small minority among the elected members – have produced “false science” but have neither massively plagiarized nor attacked the peer review system. They rather provided, as good forgers, the expected raw material to journals. However, over the last 10 years, there has been concern about how reviewers or publishers can indirectly influence the science produced, in a more subtle way. “Coerced citations”, “fake peer review” and “cartel citations” are all designations of practices that do not directly fudge the content of articles, but act on the margins by hacking into the journal peer review process.

So, the old criticisms about the misdeeds of anonymity in journal peer review4 were reborn at great expense and many debates about “transparent peer review” took place. Where in the past editors and authors were at the helm of these discussions, now the publishers are in charge and, above all, Elsevier. The company provided two in-house researchers with access to his back office and they were able to compare the bibliography of the manuscripts with those of the published articles and check whether added references were coauthored by reviewers of the manuscript. Unsurprisingly, the authors of When Peer Reviewers Go Rogue concluded that there was a manipulated citation, even if its level is quite low (0.79%).

At the same time, a research team led by the famous John Ioannidis sought to build a “clean” base of citations for the most cited researchers. For them, this meant being able to separate self-citations from the rest, and it was on this occasion that they made a surprising discovery: the staggering intensity in the level of self-citation of some colleagues. Indeed, as your level of citations rise, you expect that they are all the more coming from distant colleagues. Not for everybody:

Vaidyanathan, a computer scientist at the Vel Tech R&D Institute of Technology, a privately run institute, is an extreme example: he has received 94% of his citations from himself or his co-authors up to 2017 (…) He is not alone. The data set, which lists around 100,000 researchers, shows that at least 250 scientists have amassed more than 50% of their citations from themselves or their co-authors, while the median self-citation rate is 12.7% ((Nature, Hundreds of extreme self-citing scientists revealed in new database, 19th August 2019)).”

But then, what are the Highly Cited Researchers, whose numbers are one of the components of the Shanghai Ranking, actually doing? Are they renowned for their influential results or are they more adept at being manufacturers on the citation chain? Bibliometricians would say that a “high” self-citation rate is not necessarly a sign of fraud, but that a detailed inquiry woud be neeeded This is where we return to our newest member of the Hall of Fame, whose work is worthy of close consideration.

A perfect hacker,
always greedy for citations

It all starts with a mundane story: a reviewer asks for additional references in a manuscript. But the request itself is not so trivial: it consists of 35 references, the vast majority of which are co-signed by him, and he indicates that his recommandation to editors, on whether or not to accept the manuscript, will depend heavily on this inclusion. It should also be specified that it is not for a single review that this request is made, but for each of the manuscripts passed through his hands. In describing their decision to ban this unnamed reviewer, editors did not indicate how long this practice has existed. Indeed, it is unusual, to say the least, to request the addition of so many references, and one might question their own responsibility in this matter if it lasted as they reference to the “most recent reviews” seems to imply. To which they reply:

One might ask how this reviewer got away with submitting multiple reviews containing coercive requests for citation before being banned. The shortest explanation is that excessive self-citation demands are generally not seen as an ethical problem until a pattern is established, and a decentralized peer-review system is not amenable to detecting patterns“((Wren, Jonathan D., Alfonso Valencia, and Janet Kelso. “Reviewer-coerced citation: case report, update on journal policy and suggestions for future prevention.” (2019): 3217-3218.)).

And in fact they inquire in other journals, and that suggested the same pattern of behavirour for this reviewer. A year later, in early 2020, the investigation leads to an editorial in another journal, the Journal for Theoretical Biology, (JTB), which reveals perhaps the most complete case of manipulated citation to date. Indeed, the hacker is no longer a simple reviewer there, but a “handling editor” for JTB, which enables him to act at several stages of the manuscript, with a single objective: to accumulate citations.

  1. He took the charge of many manuscripts from his research centre to ensure that they are well treated (conflict of interest).
  2. He chose reviewers requested by the authors, or designated colleagues from his own centre (conflict of interest) or even reviewed them himself under a false name (ghost peer review).
  3. In many cases, with the return of the reviews, he would ask for the title of the article to be changed so that it explicitly refers to his own algorithm, as well as a discussion of his own work in the introduction and conclusion (coerced citations).
  4. As a result, he requested the addition of a very large number of references (up to more than 50) to the bibliography of the manuscript (coerced citations).
  5. Just before the acceptance of the manuscript, he was added as co-author of the article (gift authorship).

We therefore observe two complementary types of behaviour. On the one hand, hidden from the outside, it consists in hacking the flow of the peer review journal, capturing the evaluation process to ensure that the articles most “favourable” to its citation count are actually published – and sometimes with his coauthorship. On the other hand, visible to the authors and perhaps the editor-in-chief and publisher, the aim is to hack the byline, content and references of the manuscript by making imperative requests for inclusion. Thus, these ordinary manuscripts became articles loaded with citations from the hacker.

It can be noted that at this stage, the name of the reviewer is not given by JTB, which caused some to make educated guess on Twitter. News articles in Nature among others, soon follow and revealed his identity: Kuo-Chen Chou, a retired chinese-american biophysicist. We then learn that he has been for years a member of the Highly Cited Researcher “club”5. So, as usual, this extraordinary case will be treated as “rare”, counter-measures have been taken such as an algorithm written by one of the Bioinformatics editor. But the ordinary gaming will still happen, would it be in so-called predatory journals or “prestigious” publishers, with smarter colleagues less greedy on citations and not obsessed with the HCR club. Will you be one of them?6

From sharing to versioning to citing to retracting or… How preprints became quasi-articles

The forms of communication in academic communities are very diverse: articles, seminars, books, colloquia, mailing lists, posters, letters, workshops, proceedings,… The reasons why each one is chosen are multiple and the formats live their own life with new uses, far beyond the initial intentions of their creators. As we will see, preprints, though they have a relatively short history, followed complex patterns, to become something more than shared documents.

It is first necessary to agree on the designation of these entities: working papers, discussion papers, e-prints, preprints will be considered in this post as equivalents. All are written texts, produced by authors without any form of certification, and are made available without any paywall on a perennial web address. Contrary to Wikipedia, we don’t distinguish them on the basis of their future publiation in a journal. We will also ignore the issue of their licensing for two reasons: historically, preprints have existed long before the release of CC licenses – and many of them continue to be unlicensed; pragmatically, because our focus here is on the use of preprints, not their re-use.

Prior to the electronicization of scholarly communication, some disciplines had already experienced preprints, notably psychology and biomedical sciences. This meant that paper manuscripts circulated by mail, with associated quite high material costs (reproduction, stamps). This was not the primary reason for the cessation of certain practices: in biomedicine, publishers were vigilant and their editors-in-chief allies declared a ban on the publication of manuscripts that had already been circulated. On the other hand, physics, especially high-energy physics, pioneered these practices and continued to generate these mail flows before transferring them to the electronic world in the 1970s. Using the compactness of the TEX format, these preprints started to be distributed by email and then Paul Ginsparg had the idea of building an automatic BBS, basically inventing ArXiv.

E-prints servers as competitors of journals?

Until then, in all disciplines, usage has essentially been the same: to facilitate the consideration and discussion of recent research and results, by circumventing the obstacle of delays of publication in journals. Admittedly, a large number of conferences had adopted the practice of proceedings, thus allowing a reduction in this delay, but they remained then very largely attached to the world of paper printing. Following the success of ArXiv, several e-print services were launched in the mid-1990s and Steven Harnad predicted their pre-eminence over journals as the central venue for distribution:

“the best people start putting stuff and readers start saying :’Why wait for the journal to come out? I have to teach this stuff, I have to know this stuff, I can get it to the archive’ and then the libraries come around and say ‘should we order this journal?’ and the scientist says ‘I don’t care, I no longer read in paper’.”

It seems obvious that this prediction did not come true, far from it, and the 2000s saw a world divided between a few disciplines massively practicing preprinting (physics, mathematics, computer science, economics) and the rest of the academic world ignoring them superbly. Nevertheless, their uses – both on the authors’ and the readers’ side – have started to compete with the journals ones. In a peer reviw fashion, the “raw” circulation of a manuscript for discussion regularly produced new versions of a preprint. On ArXiv, more than a third of the preprints exist in 2 versions, and more than 10% exist in 3 versions; or even more as Hirsch’s famous manuscript inventing the h-index had 5 versions, 4 of them before submission to PNAS. On the readers’ side, researchers soon started to cite not only published papers, but also preprints – then often called e-prints, on a massive scale.

These new reading and referencing practices have led to a vast literature on the citation advantage of open access articles over those available only through subscription and its paywalls1. Beyond this possible advantage – monetarised by big publishers for their hybrid journals in a commercial version of open access – these practices shed light on the change in status from simple “manuscripts” to texts integrated into the published literature. To completly get them out of their grey literature status, Paul Ginsparg had proposed as early as 1996 to add overlaid information on preprint servers, which led on the one hand to the creation of journals overlays proper, and on the other hand to various recommendation devices for preprints, among other texts.

The accelerated life cycle of preprints

The “standardization” of preprints through citation or certification is not the only notable development. Indeed, the recent disciplinary extension of preprints servers, in what is often described as a second wave2) is a significant development and has consequences for their uses. Let us take the example of life sciences, with the development of biorXiv, a platform launched in 2013 and published 30,000 preprints in the year 2019.

From this video put online at the time of the platfom inauguration, we will retain two elements: fastness and discussion. If high energy physicists, because of the weight of the infrastructures, work organization and authorship practices are used to live in a world with little publishing competition3 , this is not the case for many computer scientists who already published on ArXiv, especially in the artificial intelligence branch. Also, flag-planting to estabilish priority and (thoretically) gain the scientific credit has been a common operation on ArXiv, the use of timestamp by the server being a certfication of the order of arrival. If this fastness is also important in life sciences to avoid getting scooped, it shall be equally considered in contrast with the slowness of journals : speed of publication has often been an argument for different outputs, and the tension between rapid dissemination and quality of certification is at the heart of the history of the peer review in journals4.

For life scientists and especially early carreer researchers with short-term contracts, speed is less a question of priority than to simply see their results being widespread to be able to build some credit for their next assignment. Until preprints, no publications meant no credit. Now, they have at least something, especially since some organization have recognized preprints as legitimate outputs for CVs in grant applications. Of course, they still need publication in journals, which leads us to the role of discussions. As we have seen, in the case of ArXiv, discussions often feed a release cycle in the form of new preprints. In life sciences, this is apparently much less the case: a recent study by Kent Anderson5. shows that the majority of preprints were posted after they were submitted to a journal, so the “discussion » rather than feedback from the readers of the preprint takes the form of a peer review within a given journal

From fastness to emergency:
Preprints can be retracted too

At this point, we need to address the question of the targeted audiences for preprint servers: if it was initially pure academic community exchanges, things have changed with the popularity of social networks. Indeed, the cited Knowledge Exchange report highlighted the crucial role played by Twitter in the dissemination of preprints by their authors or platforms themselves. This dissemination to fringe and non-academic audiences has several consequences, such as the reuse of preprints by maginalised communities or communities with minority knowledge and beliefs. This is also the case for links to blogs included in ArXiV trackbacks for which it is very difficult to reach a consensus on the “serious” or “eccentric” character of a website.6. If Anderson concluded that the promise of a discussion was not kept within the platform in the case of biorXiv, it doesn”t necessarly mean that it is limited to journal peer review, as an unexpected event has just shown us.

In fact, the 2019-nCov coronavirus has been a test for biorXiv as it became the forefront of scientific information. Yet, since the 2003 SARS virus, the international health community, strongly pushed by WHO, seemed to have favored data and information sharing over scientific credit or patents. In recent epidemics, even the paywalls of big publishers have been opened in order to maximise the sharing of the existing knowledge. Now that biorXiv has been strongly established, it is the easiest legal way to combine sharing, speedness and some credit coming from priority7 And indeed, the preprint server has been flooded with coronavirus papers.

This new disclaimer – which specifies in the current case a general policy stated at the top of each preprint – emphasizes the potential audience of preprints, media. For long, the majority of senior life scientists have feared that uncertified preprints would be taken for granted and that a flow of “bad science” would be given to lay audiences. And their strongest fears apparently came true, as an article suggesting the artificial nature of the current virus quickly fed the conspiracy sites and flows, “proving” the epidemic could only be, at the very least, the result of a failed experiment. But the preprint publicity is more ambiguous : as its links spread, it was severely criticized, in a very well-argued way, by colleagues. Moreover, biorXiv is one of the few preprint servers that has included a comment feature attached to the preprints it hosts. And this paper has received a lot of them! So much so that the preprint was retracted less than 2 days after its publication – or more exactly the authors withdrew it following all these comments, whereas previously the retraction of a preprint was envisioned only in case his published heir would have previously endured this exact fate.

The interpretation of this ultra-fast life cycle is of course contrasted: the creators of Retraction Watch see it as a victory for science in preprint mode, while K. Anderson and others consider that such an article would never have appeared in a top-level journal. But the outcome of this debate on journals vs. preprint servers quality should not obscure the profound transformations of preprints. The Harnad vision began to come into reality more than 20 years later, but in a twisted way. While preprint servers didn’t replace journals, preprints have become quasi-articles: used for priority, have a DOI, generate some scientific credit, read and cited, change through at least informal discussion processes, appear on CVs and are archived, generate media interest. And now even if by name they are pre-publications, they are submitted to the stringest post-publication peer review decision.

The short history of the h-index or… being one click away to determine whether you are a succesful scientist

Sometimes, newness really happens in the academic world. Take bibliometrics indicators: for at least a century they have been usally proposed and discussed by specialized scientists from a scientometrics background in their field journals (currently JASIST, Scientometrics, …) and nobody else cared, at least for some time. But in 2005, something very peculiar happened: the h-index was coined by a total stranger to that field and had an instant success, which endures until now. How did that happen and why such a success?1

Physicist J.E. Hirsch proposed the h-index in a working paper posted on August 3rd, 2005 on arXiv, the famous open archive developed by physicists in Los Alamos. In his manuscript, he discussed the issue of comprehensively evaluating a researcher and wished, in a radical way, to subsume their whole career into a simple and practical measurement: an integer number. To do so, he considered that the production and its uses had to be taken into account through a citation measurement. So, number h is the greatest number for which h articles by an author have at least h citations. For example, for 5 articles cited at least 5 times, h is 5; likewise, for 50 articles cited at least 50 times each, h is 50.

Yet, the use of algorithms concerning authors was not new. Eugene Garfield, the founder of the Institut for ScIentific Information (ISI), claimed to regularly predict Nobel prizes using the Science Citation Index and had then developed the “ISI highly cited”, presenting results for a tiny fraction of “top”researchers ; similarly, a few disciplines like economics and management had a long tradition of ranking “top authors”. But, to our knowledge, no algorithm had to that date been specifically designed to evaluate authors . This novelty also comes from the lack of consideration Hirsch displayed for the existing litterature: there were only four references in his manuscript and only one in the field.

This departing from the scientometric tradition enabled Hirsch to make several shifts. Firstly, he did not take into account journals in which articles are published, probably because in high energy physicists, journals are used to archive knowledge more than to make discoveries public. Secondly, he excluded the pitfalls of the number and order of coauthors, which are of little relevance in physics but crucial in biomedical research for individual evaluation. Thirdly, his index combined two elements considered as heterogeneous in the scientometric tradition: production on the one hand, and use on the other. And finally fourthly, whereas scientometricians are always very cautious about individual analysis and save it for “outliers”, Hirsch proposed a measurement which applies to all researchers, and as a cherry on the cake, argued that it would be of some use for the allocation of research funds.

How did he make such a bold move? Based on numbers crunched in the case of high-energy physicists, HIrsch forged a model of the “successful scientist”. As the result of his algorithm very much depends on the duration of a researcher’s career, the h divided by the number of years of the career was considered as a good indicator by Hirsch.


“An h index of 20 after 20 years of scientific activity, characterizes a successful scientist. […] an h index of 40 after 20 years of scientific activity, characterizes outstanding scientists, likely to be found only at the top universities or major research laboratories. […] an h index of 60 after 20 years, or 90 after 30 years, characterizes truly unique individuals”.


At that point, Hirsch woud have probably been considered as a bibliometrics crackpot, a talented physicist that happens to crunch citations numbers in his pastime and posting his “personal views” on a website.

An instant success,
an impressive series of implementations

To the surprise (and probably horror) of the scientometrics community, the h-index was taken up at a staggering rate. As soon as his manuscript had been available on ArXiv, Hirsch received extensive feedback from his physicist colleagues and, in view of the shared enthusiasm, an open archive specialized in high energy physics, SPIRES (Stanford Physics Information REtrieval System), implemented the algorithm on its dataset only two weeks later. The same day, August 17th, 2005, Nature presented Hirsch’s proposition and highlighted his colleagues’ enthusiasm, while an editorial entitled “Rating Games” discussed the respective role of metrics and peer review. Shortly afterwards, in November 2005, two of Hirsch’s colleagues published the manuscript as an article2 in the Proceedings of the National Academy of Sciences, thus confirming physicists’ keen interest in this new measurement.

The popularization of the h-index took a new turn a yer later with a bibliometric tool developed by Ann-Will Harzing, Publish or Perish (PoP). In October 2006, this management professor at the University of Melbourne put online a small software, operationalizing the h-index calculation. That way, for any author whose name is entered by the user, irrespective of the discipline, PoP calculates their h-index in a single click, based on the nascent Google Scholar dataset. This tool could be downloaded for free and has thus allowed the magic algorithm to reach users far beyond audiences specialized in scientometrics. Researchers and institutions adopted this bibliometric tool so fast that the British Medical Journal published a spoof article describing the different pathologies it generates. Meanwhile, in May 2007 Elsevier had included the h-index in Scopus; Thomson-Reuters likewise had changed its “ISI Highly Cited” and integrated this index into the WoS in 2008. Thus, in just three years, individual measurement became a practical operation drawing on bibliometric tools easily accessible to each researcher.

This cycle of implementation was provisionally finalized by the opening of Google Scholar Citations (GSC) in the summer of 2011. With this new service, every academic could create and have control on her/his profile page on Google Scholar, and could decide to make it public or not. Whatever the choice, GSC would then automatically compute three metrics:
the widely used h-index, the i-10 index, which is the number of articles with at least ten citations, and the total number of citations to your articles.
At this point, the definition of the h-index wasn’t anymore needed and thousands of academics quickly made theirs available online. As Paul Wouters and Rodrigo Costas soon noted in their 2012 manuscript, this was a typical example of what they named “technologies of narcissism”, a mirror through which you and others would look in order to measure your influence, evaluate your importance, worry about your deficiencies.

From journals to articles to authors:
new policies for evaluation

Then, despite professional scientometricians harshly criticizing the h-index for its crudeness, pointing out its variations and limits or taming it to make a g-index or a v-index, the utopic/dystopic vision of Hirsch had come into reality. Conversely, it is because of its very crudeness that made it easier to implement in databases & more readable to lay researchers. But its availability is not sufficient to explain the duration and intensity of uses – the orignial paper will probably pass the 10.000 citations mark in 2020. There are two main and very different reasons for its popularity, which we must analytically distinguish. The first one is the implementation of the algorithm to new objects, such as research groups or even journals. Confronted with its unexpected success and eager to use the new data avaialable, scientometricians got into an h-index frenzy3. While the dominant popular bibliometrics index, both within the community and outside of it, had been for 30 years the Journal Impact Factor (JIF) then prouced and owned by Thomson ISI, the growing success of the h-index made it a challenger in the bibliometrical index “market”. Many papers compared the pros and cons of each algorithm, based on different datasets.

Nevertheless, this “good index” competition shouldn’t hide a second reason for which the h-index became so popular and discussed. Its use was sustained by a political agenda in assesment and evaluation, best represented by the San Francisco Declaration on Research Assessment (DORA) published in 2013. This complex text is often subsumed as an anti-bibliometrics statement, in which signing institutions promise they won”t use the JIF as a way to evaluate research, would it be for hiring, promoting, giving grants, etc. Beyond this simple vision, there are more nuanced recommandations that oppose journal-based metrics, but don’t refuse bibliometrics as a whole. JIF is seen as a bad way to perform quantified assesment, where article-level metrics, whatever they are (citations, downloads, views, social networks mentions…) are more realistic of the “impact” of a given research.

The problem with these new metrics is that nobody really knows what they are used for and what they really mesure4. Consequently, the most popular article-level metric remains the number of citations in a given database (Web of Science, Scopus, Crossref, Google Scholar). Rather than summing these numbers for a given journal, the aggregation is made on a given author. It is so simple to perform on the same databases, that what was absurd a few years ago has become natural. The “h revolution” therefore went beyond Hirsch’s own vision on two points. Firstly, his h-index was to be used for senior scientists, it is now also being applied to/by early and mid-carrer researchers as a more “ethical way” to judge their impact. Secondly, its extension goes hand in hand with a potential transformation of the model of scientific communication, to a post-journal world, in which any kind of text could be cited and counted. Rather than highlighting the fact that you actually passed the test of supposed prestigious journals, you just now give your h number and academic age, so everybody checks whether you really are the successful scientist you pretend to be .
