Peru has increased its scientific production in recent years as a result of the 2014 university reform and the licensing process of universities and medical schools by the National Superintendence of Higher Education (SUNEDU) ^{1 , 2}. In addition, institutions with higher scientific production are better positioned in university rankings ^{3 , 4}; likewise, their teachers and students are recognized as researchers (RENACYT researcher) by the Peruvian National Council for Science, Technology, and Innovation (CONCYTEC) ⁵.

This situation has led to a greater interest among the university community regarding research and publication in indexed journals, with changes in research training strategies such as the acceptance of theses in scientific article format ^{6 , 7}, development and support for research groups ⁸, as well as creating incentives for teachers who publish ⁹, including the bonus for research teachers that exists by law for public universities ¹⁰, among others.

One of the consequences of these changes is that both researchers and institutions may favor the publication of certain types of manuscripts to increase their production, such as conferences in congresses (proceeding papers) and letters to the editor (particularly commentary letters, on the same topic, published in different journals), which are more rapidly published, and are reflected in a growing trend in the country, especially the former (Figure 1).

Research incentive and recognition policies have a positive purpose for the institutions, the country, and the researchers. However, there are at least five elements in this Peruvian process that are a potential breeding ground for research malpractices to occur if there are not adequate controls:

This has contributed to a “publish or perish” culture that can lead to bad scientific practices such as authorship issues (gifted, invited) ¹¹, redundant publication ¹², plagiarism ¹³, data manipulation ¹⁴, as well as publication in predatory journals ¹⁵.

At least 1% of the production from the nine universities with the highest scientific output is found in potentially predatory journals indexed in Scopus; there is a growing trend over the years, and it is suspected that this may occur more frequently in other universities with a recent interest in research ¹⁶. Predatory journals prioritize self-interest, and their sole purpose is profit. They are characterized by presenting misleading or false content, do not follow good editorial and publication practices, lack transparency, and use aggressive strategies to seek articles for publication ¹⁷. In addition, they tend to have -if they do have it- a quick and insubstantial peer review process that does not guarantee the quality of the content; they also have short publication periods ^{( 18 , 19}.

In recent years, along with the sale and purchase of theses ²⁰, there has been a proliferation of advertisements from local companies dedicated to “helping” university professors to become RENACYT researchers, offering them, in the best scenario, to publish their studies or theses in journals included in Latindex, often linked to the same company. In other cases, they offer the entire research process up to publication, without the certainty that there was a real study behind it (there would be manipulation of data or plagiarism). Advertisements have also been detected from companies that offer and buy authorships, the cost of which increases as the level of indexing and impact of the journal increases.

These types of fraudulent organizations are referred to as “paper mills” and are a recent and growing global problem, aimed at distorting the scientific research and publication process ^{11 - 14}. The Committee of Publication Ethics (COPE) describes it as “process by which manufactured manuscripts are submitted to a journal for a fee on behalf of researchers with the purpose of providing an easy publication for them, or to offer authorship for sale” ²¹. These manuscript mills may include one or more of these practices, which are grouped into manuscript ghostwriting, simulation of the research process, buying and selling manuscripts, and manipulation of the research process (Table 1) ²².

It is necessary to typify this kind of malpractice, which in turn includes other kinds within itself, in order to detect and sanction it. In the first place, it is necessary to identify the manuscript mills operating in the country and the journals associated with them. Likewise, the people who promote them, who, if they are researchers affiliated to an academic institution, should be investigated, and sanctioned.

In some cases it is possible that the teacher, out of ignorance, acquires this service thinking that it is a form of support for the writing and publication of articles, but in other scenarios there is a direct intention to commit fraud since they seek to be authors of research that they have not done or knowing the processes they prefer this way to quickly reach the goal of being recognized as a researcher. As in the case of plagiarism ²³, the typification of the “use of manuscript mills” malpractice exists, and the sanction will depend on the aggravating and extenuating factors identified during the investigation process.

Currently, the change in the requirements to be a researcher recognized by CONCYTEC has partially solved the problem by no longer including Latindex in the classification ⁵; however, two challenges remain regarding the control of the editorial function of these manuscript mills. The first aspect is that some of these fraudulent companies have journals that are in Latindex and, since they are no longer an indicator for evaluation by CONCYTEC, they will request their inclusion in SciELO or in the Emerging Source Citation Index of Web of Science, which could be more accessible than entering Scopus or the Science Citation Index Expanded. Secondly, some offer the publication of “research books” and even scientific congresses where they guarantee the publication of the work in their journals or as books or chapters that they also edit (Table 1). CONCYTEC through its National Committee of Scientific Integrity should try to identify, investigate, and sanction them when appropriate.

To discourage the use of manuscript mills, universities should train their faculty and students on the correct processes of research and publication, but it is also necessary to identify, investigate and sanction those who use these services. For this purpose, the Scientific Integrity Offices/Units/Committees should function properly, which are different from the Institutional Research Ethics Committees, since unlike the latter - which seek to protect the research subject - the former watch over good research practices and have the power to investigate and sanction those who commit misconduct ^{24 , 25}.

Finally, it is necessary to continue with the policies already implemented to promote research, since they contribute to the country’s development. Integrity and honesty are inherent characteristics of research work, both at the level of individuals and institutions. Therefore, bad practices should be identified, investigated, and sanctioned, with emphasis on those that are growing, such as manuscript mills.
