How To Write A Scientific Review?

How To Write A Scientific Review
Tips for Writing a Scientific Review Article – ASCB Photo by John Fleischman Toward the end of my graduate school training I had an opportunity to write a scientific review article. It was quite a learning experience and one that was well timed. I was close to completing my PhD, and the chance to assimilate all the literature in the field and interpret findings of recent scientific articles in an informative scientific review was exciting.

Give yourself plenty of time to write a scientific review. Compiling years of scientific progress into a short review article is not easy and it requires good understanding of the literature and implications of the discoveries made thus far. Most importantly, stay on time and submit your review article by the deadline. Start early, spend time reading literature extensively, and pen your thoughts as you go along. Make an outline and decide on the main topic for the review. It is easy to digress and include all the information in the field; however, this would not be useful to readers. Be aware of journal requirements. Decide where you are going to publish your review and be sure to read journal requirements for submission of the review. It is good to strictly adhere to journal requirements such as number of papers cited or word/page limits. Be well versed with the literature. It is important to know about the initial studies and also know of the latest discoveries (i.e., be scholarly). A good review summarizes relevant discoveries, discusses implications, and speculates on the future of the field. Make notes while reading the literature, It is impossible to remember every article that you read along with your thoughts or interpretations. Try making notes while reading. It will help give a structure to your review article. Analyze published scientific literature. As a scientist it is imperative to assimilate data and understand its implications or caveats. A scientific review article is a good place to discuss these issues and point out how caveats can be addressed in the future. Discuss significant findings. This allows the author(s) to elaborate on whether certain pathways/observations are conserved across species. Also discuss differences and speculate on how the different regulation in other species may be advantageous. Such evolutionary conservation is not only biologically significant but can also help readers understand how a process is regulated. Utilize graphics. Include charts or figures to depict key points of the review. A useful tool employed in many reviews is a timeline that details significant discoveries that have contributed to better understanding of the field. Request Feedback. Your lab mates, mentor, or colleagues in your university will be happy to read drafts and provide feedback. They may help with different perspectives or can also help you interpret certain studies in new ways you hadn’t thought of. Discussing your review with peers will definitely improve it and help prevent inaccuracies. Discuss the future of the field. Get your lab mate’s and mentor’s views on the future to determine if there is a consensus on where they think the field is headed. Speculate on how the future will improve our understanding of the field.

Most importantly take the time to write a scientific review! It helped me develop as a scientist. I understood the process of writing a scientific review, learned to be accurate yet consistent with scientific facts/discoveries, and got more experience critiquing scientific literature.

What should a scientific review include?

A scientific literature review usually includes a title, abstract, index, introduction, corpus, bibliography, and appendices (if needed). Present the problem clearly. Mention the paper’s methodology, research methods, analysis, instruments, etc. Present literature review examples that can help you express your ideas.

How do you start a scientific review article?

We recommend that, in addition to a title and abstract, all review articles include a general introduction to the topic, a main section that discusses the core topic in depth, with subheadings to demarcate subtopics, and a concluding section that summarises the take-home messages of the article and key future

What is scientific review in research?

Scientific Review includes the initial concept and full protocol review, annual and quadrennial review of the ongoing protocol, and review of substantive amendments to the protocol that pose new scientific questions.

What are the characteristics of a good scientific review?

What makes a ‘good’ review article? Some reflections and recommendations

1. Originality.
2. Advances knowledge and original thinking.
3. Theory-based.
4. Evidence-based.
5. Accurate, comprehensive and rigorous.

How is a review structure?

Enclosed you will find an evaluation sheet designed to help you with your review. It is divided into two major parts. The first part should consist of your recommendation and comments to the editor alone, while the second part should contain your comments to the authors and the editor.

How long is a scientific review paper?

Overall length of a research paper – Let’s start by looking at the maximum word count allowed in some of the well-known journals. Note that the numbers reported in this table include the Abstract, Figure legends and References unless otherwise specified:

Journal Maximum Length Allowed for Original Research Papers Maximum Length Allowed for Review Papers
Nature 9,000 words 9,000 words
Elsevier Journals 8,000 words 8,000 words
Cancer 5,000 words 6,000 words
Neurology 4,850 words 5,350 words
Science 4,500 words 6,000 words
Blood 4,000 words 4,000 words
Annals of Internal Medicine 3,775 words 4,275 words
Journal of Clinical Psychiatry 3,250 words 5,250 words
Pediatrics 3,000 words 4,000 words

excluding figure legends excluding references ⚠ Note A review paper is either a systematic review or a meta-analysis, and an original research paper refers to either an observational or an experimental study conducted by the authors themselves. Notice the large variability between these journals: The maximum number of words allowed ranges between 3,000 and 9,000 words.

Article Length (Word Count) Article Length (Sentence Count) Article Length (Paragraph Count)
Minimum 271 words 12 sentences 4 paragraphs
25th Percentile 3,118 words 125 sentences 26 paragraphs
50th Percentile (Median) 4,113 words 166 sentences 34 paragraphs
Mean 4,539 words 184 sentences 40 paragraphs
75th Percentile 5,494 words 220 sentences 46 paragraphs
Maximum 48,163 words 3,438 sentences 1,736 paragraphs

90% of research papers have a word count between 2,023 and 8,284. So it will be a little weird to see a word count outside of this range. Our data also agree that a typical review paper is a little bit longer than a typical original research paper but not by much (3,858 vs 3,708 words).

What are the parts of a scientific review article?

Nearly all journal articles are divided into the following major sections: abstract, introduction, methods, results, discussion, and references. Usually the sections are labeled as such, although often the introduction (and sometimes the abstract) is not labeled.

What are the two main types of scientific reviews?

The main distinction of scientific research is between quantitative and qualitative research.

What is the introduction of a scientific review?

Abstract – An article primarily includes the following sections: introduction, materials and methods, results, discussion, and conclusion. Before writing the introduction, the main steps, the heading and the familiarity level of the readers should be considered.

Writing should begin when the experimental system and the equipment are available. The introduction section comprises the first portion of the manuscript, and it should be written using the simple present tense. Additionally, abbreviations and explanations are included in this section. The main goal of the introduction is to convey basic information to the readers without obligating them to investigate previous publications and to provide clues as to the results of the present study.

To do this, the subject of the article should be thoroughly reviewed, and the aim of the study should be clearly stated immediately after discussing the basic references. In this review, we aim to convey the principles of writing the introduction section of a manuscript to residents and young investigators who have just begun to write a manuscript.

Why are scientific reviews important?

Peer review has been defined as a process of subjecting an author’s scholarly work, research or ideas to the scrutiny of others who are experts in the same field.

It functions to encourage authors to meet the accepted high standards of their discipline and to control the dissemination of research data to ensure that unwarranted claims, unacceptable interpretations or personal views are not published without prior expert review.

  • Despite its wide-spread use by most journals, the peer review process has also been widely criticised due to the slowness of the process to publish new findings and due to perceived bias by the editors and/or reviewers.
  • Within the scientific community, peer review has become an essential component of the academic writing process.

It helps ensure that papers published in scientific journals answer meaningful research questions and draw accurate conclusions based on professionally executed experimentation. Submission of low quality manuscripts has become increasingly prevalent, and peer review acts as a filter to prevent this work from reaching the scientific community.

The major advantage of a peer review process is that peer-reviewed articles provide a trusted form of scientific communication. Since scientific knowledge is cumulative and builds on itself, this trust is particularly important. Despite the positive impacts of peer review, critics argue that the peer review process stifles innovation in experimentation, and acts as a poor screen against plagiarism.

Despite its downfalls, there has not yet been a foolproof system developed to take the place of peer review, however, researchers have been looking into electronic means of improving the peer review process. Unfortunately, the recent explosion in online only/electronic journals has led to mass publication of a large number of scientific articles with little or no peer review.

This poses significant risk to advances in scientific knowledge and its future potential. The current article summarizes the peer review process, highlights the pros and cons associated with different types of peer review, and describes new methods for improving peer review. Key words: peer review, manuscript, publication, journal, open access Peer Review is defined as “a process of subjecting an author’s scholarly work, research or ideas to the scrutiny of others who are experts in the same field” ().

Peer review is intended to serve two primary purposes. Firstly, it acts as a filter to ensure that only high quality research is published, especially in reputable journals, by determining the validity, significance and originality of the study. Secondly, peer review is intended to improve the quality of manuscripts that are deemed suitable for publication.

Peer reviewers provide suggestions to authors on how to improve the quality of their manuscripts, and also identify any errors that need correcting before publication. The concept of peer review was developed long before the scholarly journal. In fact, the peer review process is thought to have been used as a method of evaluating written work since ancient Greece ().

The peer review process was first described by a physician named Ishaq bin Ali al-Rahwi of Syria, who lived from 854-931 CE, in his book Ethics of the Physician (). There, he stated that physicians must take notes describing the state of their patients’ medical conditions upon each visit.

  • Following treatment, the notes were scrutinized by a local medical council to determine whether the physician had met the required standards of medical care.
  • If the medical council deemed that the appropriate standards were not met, the physician in question could receive a lawsuit from the maltreated patient ().

The invention of the printing press in 1453 allowed written documents to be distributed to the general public (). At this time, it became more important to regulate the quality of the written material that became publicly available, and editing by peers increased in prevalence.

  • In 1620, Francis Bacon wrote the work Novum Organum, where he described what eventually became known as the first universal method for generating and assessing new science ().
  • His work was instrumental in shaping the Scientific Method ().
  • In 1665, the French Journal des sçavans and the English Philosophical Transactions of the Royal Society were the first scientific journals to systematically publish research results ().

Philosophical Transactions of the Royal Society is thought to be the first journal to formalize the peer review process in 1665 (), however, it is important to note that peer review was initially introduced to help editors decide which manuscripts to publish in their journals, and at that time it did not serve to ensure the validity of the research ().

It did not take long for the peer review process to evolve, and shortly thereafter papers were distributed to reviewers with the intent of authenticating the integrity of the research study before publication. The Royal Society of Edinburgh adhered to the following peer review process, published in their Medical Essays and Observations in 1731: “Memoirs sent by correspondence are distributed according to the subject matter to those members who are most versed in these matters.

The report of their identity is not known to the author.” (). The Royal Society of London adopted this review procedure in 1752 and developed the “Committee on Papers” to review manuscripts before they were published in Philosophical Transactions (). Peer review in the systematized and institutionalized form has developed immensely since the Second World War, at least partly due to the large increase in scientific research during this period ().

It is now used not only to ensure that a scientific manuscript is experimentally and ethically sound, but also to determine which papers sufficiently meet the journal’s standards of quality and originality before publication. Peer review is now standard practice by most credible scientific journals, and is an essential part of determining the credibility and quality of work submitted.

Peer review has become the foundation of the scholarly publication system because it effectively subjects an author’s work to the scrutiny of other experts in the field. Thus, it encourages authors to strive to produce high quality research that will advance the field.

Peer review also supports and maintains integrity and authenticity in the advancement of science. A scientific hypothesis or statement is generally not accepted by the academic community unless it has been published in a peer-reviewed journal (). The Institute for Scientific Information ( ISI ) only considers journals that are peer-reviewed as candidates to receive Impact Factors.

Peer review is a well-established process which has been a formal part of scientific communication for over 300 years. The peer review process begins when a scientist completes a research study and writes a manuscript that describes the purpose, experimental design, results, and conclusions of the study.

The scientist then submits this paper to a suitable journal that specializes in a relevant research field, a step referred to as pre-submission. The editors of the journal will review the paper to ensure that the subject matter is in line with that of the journal, and that it fits with the editorial platform.

Very few papers pass this initial evaluation. If the journal editors feel the paper sufficiently meets these requirements and is written by a credible source, they will send the paper to accomplished researchers in the field for a formal peer review. Peer reviewers are also known as referees (this process is summarized in ).

  • The role of the editor is to select the most appropriate manuscripts for the journal, and to implement and monitor the peer review process.
  • Editors must ensure that peer reviews are conducted fairly, and in an effective and timely manner.
  • They must also ensure that there are no conflicts of interest involved in the peer review process.

Overview of the review process When a reviewer is provided with a paper, he or she reads it carefully and scrutinizes it to evaluate the validity of the science, the quality of the experimental design, and the appropriateness of the methods used. The reviewer also assesses the significance of the research, and judges whether the work will contribute to advancement in the field by evaluating the importance of the findings, and determining the originality of the research.

Additionally, reviewers identify any scientific errors and references that are missing or incorrect. Peer reviewers give recommendations to the editor regarding whether the paper should be accepted, rejected, or improved before publication in the journal. The editor will mediate author-referee discussion in order to clarify the priority of certain referee requests, suggest areas that can be strengthened, and overrule reviewer recommendations that are beyond the study’s scope ().

If the paper is accepted, as per suggestion by the peer reviewer, the paper goes into the production stage, where it is tweaked and formatted by the editors, and finally published in the scientific journal. An overview of the review process is presented in,

Peer reviews are conducted by scientific experts with specialized knowledge on the content of the manuscript, as well as by scientists with a more general knowledge base. Peer reviewers can be anyone who has competence and expertise in the subject areas that the journal covers. Reviewers can range from young and up-and-coming researchers to old masters in the field.

Often, the young reviewers are the most responsive and deliver the best quality reviews, though this is not always the case. On average, a reviewer will conduct approximately eight reviews per year, according to a study on peer review by the Publishing Research Consortium (PRC) ().

  • Journals will often have a pool of reviewers with diverse backgrounds to allow for many different perspectives.
  • They will also keep a rather large reviewer bank, so that reviewers do not get burnt out, overwhelmed or time constrained from reviewing multiple articles simultaneously.
  • Referees are typically not paid to conduct peer reviews and the process takes considerable effort, so the question is raised as to what incentive referees have to review at all.

Some feel an academic duty to perform reviews, and are of the mentality that if their peers are expected to review their papers, then they should review the work of their peers as well. Reviewers may also have personal contacts with editors, and may want to assist as much as possible.

  1. Others review to keep up-to-date with the latest developments in their field, and reading new scientific papers is an effective way to do so.
  2. Some scientists use peer review as an opportunity to advance their own research as it stimulates new ideas and allows them to read about new experimental techniques.

Other reviewers are keen on building associations with prestigious journals and editors and becoming part of their community, as sometimes reviewers who show dedication to the journal are later hired as editors. Some scientists see peer review as a chance to become aware of the latest research before their peers, and thus be first to develop new insights from the material.

Finally, in terms of career development, peer reviewing can be desirable as it is often noted on one’s resume or CV. Many institutions consider a researcher’s involvement in peer review when assessing their performance for promotions (). Peer reviewing can also be an effective way for a scientist to show their superiors that they are committed to their scientific field ().

A 2009 international survey of 4000 peer reviewers conducted by the charity Sense About Science at the British Science Festival at the University of Surrey, found that 90% of reviewers were keen to peer review (). One third of respondents to the survey said they were happy to review up to five papers per year, and an additional one third of respondents were happy to review up to ten.

  • On average, it takes approximately six hours to review one paper (), however, this number may vary greatly depending on the content of the paper and the nature of the peer reviewer.
  • One in every 100 participants in the “Sense About Science” survey claims to have taken more than 100 hours to review their last paper ().

Ulrichsweb is a directory that provides information on over 300,000 periodicals, including information regarding which journals are peer reviewed (). After logging into the system using an institutional login (eg. from the University of Toronto), search terms, journal titles or ISSN numbers can be entered into the search bar.

  1. The database provides the title, publisher, and country of origin of the journal, and indicates whether the journal is still actively publishing.
  2. The black book symbol (labelled ‘refereed’) reveals that the journal is peer reviewed.
  3. As previously mentioned, when a reviewer receives a scientific manuscript, he/she will first determine if the subject matter is well suited for the content of the journal.

The reviewer will then consider whether the research question is important and original, a process which may be aided by a literature scan of review articles. Scientific papers submitted for peer review usually follow a specific structure that begins with the title, followed by the abstract, introduction, methodology, results, discussion, conclusions, and references.

  1. The title must be descriptive and include the concept and organism investigated, and potentially the variable manipulated and the systems used in the study.
  2. The peer reviewer evaluates if the title is descriptive enough, and ensures that it is clear and concise.
  3. A study by the National Association of Realtors (NAR) published by the Oxford University Press in 2006 indicated that the title of a manuscript plays a significant role in determining reader interest, as 72% of respondents said they could usually judge whether an article will be of interest to them based on the title and the author, while 13% of respondents claimed to always be able to do so ().

The abstract is a summary of the paper, which briefly mentions the background or purpose, methods, key results, and major conclusions of the study. The peer reviewer assesses whether the abstract is sufficiently informative and if the content of the abstract is consistent with the rest of the paper.

  1. The NAR study indicated that 40% of respondents could determine whether an article would be of interest to them based on the abstract alone 60-80% of the time, while 32% could judge an article based on the abstract 80-100% of the time ().
  2. This demonstrates that the abstract alone is often used to assess the value of an article.

The introduction of a scientific paper presents the research question in the context of what is already known about the topic, in order to identify why the question being studied is of interest to the scientific community, and what gap in knowledge the study aims to fill ().

The introduction identifies the study’s purpose and scope, briefly describes the general methods of investigation, and outlines the hypothesis and predictions (). The peer reviewer determines whether the introduction provides sufficient background information on the research topic, and ensures that the research question and hypothesis are clearly identifiable.

The methods section describes the experimental procedures, and explains why each experiment was conducted. The methods section also includes the equipment and reagents used in the investigation. The methods section should be detailed enough that it can be used it to repeat the experiment ().

  • Methods are written in the past tense and in the active voice.
  • The peer reviewer assesses whether the appropriate methods were used to answer the research question, and if they were written with sufficient detail.
  • If information is missing from the methods section, it is the peer reviewer’s job to identify what details need to be added.

The results section is where the outcomes of the experiment and trends in the data are explained without judgement, bias or interpretation (). This section can include statistical tests performed on the data, as well as figures and tables in addition to the text.

  • The peer reviewer ensures that the results are described with sufficient detail, and determines their credibility.
  • Reviewers also confirm that the text is consistent with the information presented in tables and figures, and that all figures and tables included are important and relevant ().
  • The peer reviewer will also make sure that table and figure captions are appropriate both contextually and in length, and that tables and figures present the data accurately.

The discussion section is where the data is analyzed. Here, the results are interpreted and related to past studies (). The discussion describes the meaning and significance of the results in terms of the research question and hypothesis, and states whether the hypothesis was supported or rejected.

This section may also provide possible explanations for unusual results and suggestions for future research (). The discussion should end with a conclusions section that summarizes the major findings of the investigation. The peer reviewer determines whether the discussion is clear and focused, and whether the conclusions are an appropriate interpretation of the results.

Reviewers also ensure that the discussion addresses the limitations of the study, any anomalies in the results, the relationship of the study to previous research, and the theoretical implications and practical applications of the study. The references are found at the end of the paper, and list all of the information sources cited in the text to describe the background, methods, and/or interpret results.

  • Depending on the citation method used, the references are listed in alphabetical order according to author last name, or numbered according to the order in which they appear in the paper.
  • The peer reviewer ensures that references are used appropriately, cited accurately, formatted correctly, and that none are missing.

Finally, the peer reviewer determines whether the paper is clearly written and if the content seems logical. After thoroughly reading through the entire manuscript, they determine whether it meets the journal’s standards for publication, and whether it falls within the top 25% of papers in its field () to determine priority for publication.

An overview of what a peer reviewer looks for when evaluating a manuscript, in order of importance, is presented in, How a peer review evaluates a manuscript To increase the chance of success in the peer review process, the author must ensure that the paper fully complies with the journal guidelines before submission.

The author must also be open to criticism and suggested revisions, and learn from mistakes made in previous submissions. The peer review process is generally conducted in one of three ways: open review, single-blind review, or double-blind review. In an open review, both the author of the paper and the peer reviewer know one another’s identity.

  1. Alternatively, in single-blind review, the reviewer’s identity is kept private, but the author’s identity is revealed to the reviewer.
  2. In double-blind review, the identities of both the reviewer and author are kept anonymous.
  3. Open peer review is advantageous in that it prevents the reviewer from leaving malicious comments, being careless, or procrastinating completion of the review ().

It encourages reviewers to be open and honest without being disrespectful. Open reviewing also discourages plagiarism amongst authors (). On the other hand, open peer review can also prevent reviewers from being honest for fear of developing bad rapport with the author.

  • The reviewer may withhold or tone down their criticisms in order to be polite ().
  • This is especially true when younger reviewers are given a more esteemed author’s work, in which case the reviewer may be hesitant to provide criticism for fear that it will damper their relationship with a superior ().

According to the Sense About Science survey, editors find that completely open reviewing decreases the number of people willing to participate, and leads to reviews of little value (). In the aforementioned study by the PRC, only 23% of authors surveyed had experience with open peer review ().

  1. Single-blind peer review is by far the most common.
  2. In the PRC study, 85% of authors surveyed had experience with single-blind peer review ().
  3. This method is advantageous as the reviewer is more likely to provide honest feedback when their identity is concealed ().
  4. This allows the reviewer to make independent decisions without the influence of the author ().

The main disadvantage of reviewer anonymity, however, is that reviewers who receive manuscripts on subjects similar to their own research may be tempted to delay completing the review in order to publish their own data first (). Double-blind peer review is advantageous as it prevents the reviewer from being biased against the author based on their country of origin or previous work ().

  • This allows the paper to be judged based on the quality of the content, rather than the reputation of the author.
  • The Sense About Science survey indicates that 76% of researchers think double-blind peer review is a good idea (), and the PRC survey indicates that 45% of authors have had experience with double-blind peer review ().

The disadvantage of double-blind peer review is that, especially in niche areas of research, it can sometimes be easy for the reviewer to determine the identity of the author based on writing style, subject matter or self-citation, and thus, impart bias ().

  • Masking the author’s identity from peer reviewers, as is the case in double-blind review, is generally thought to minimize bias and maintain review quality.
  • A study by Justice et al.
  • In 1998 investigated whether masking author identity affected the quality of the review ().
  • One hundred and eighteen manuscripts were randomized; 26 were peer reviewed as normal, and 92 were moved into the ‘intervention’ arm, where editor quality assessments were completed for 77 manuscripts and author quality assessments were completed for 40 manuscripts ().

There was no perceived difference in quality between the masked and unmasked reviews. Additionally, the masking itself was often unsuccessful, especially with well-known authors (). However, a previous study conducted by McNutt et al. had different results ().

In this case, blinding was successful 73% of the time, and they found that when author identity was masked, the quality of review was slightly higher (). Although Justice et al. argued that this difference was too small to be consequential, their study targeted only biomedical journals, and the results cannot be generalized to journals of a different subject matter ().

Additionally, there were problems masking the identities of well-known authors, introducing a flaw in the methods. Regardless, Justice et al. concluded that masking author identity from reviewers may not improve review quality (). In addition to open, single-blind and double-blind peer review, there are two experimental forms of peer review.

  • In some cases, following publication, papers may be subjected to post-publication peer review.
  • As many papers are now published online, the scientific community has the opportunity to comment on these papers, engage in online discussions and post a formal review.
  • For example, online publishers PLOS and BioMed Central have enabled scientists to post comments on published papers if they are registered users of the site ().

Philica is another journal launched with this experimental form of peer review. Only 8% of authors surveyed in the PRC study had experience with post-publication review (). Another experimental form of peer review called Dynamic Peer Review has also emerged.

  1. Dynamic peer review is conducted on websites such as Naboj, which allow scientists to conduct peer reviews on articles in the preprint media ().
  2. The peer review is conducted on repositories and is a continuous process, which allows the public to see both the article and the reviews as the article is being developed ().

Dynamic peer review helps prevent plagiarism as the scientific community will already be familiar with the work before the peer reviewed version appears in print (). Dynamic review also reduces the time lag between manuscript submission and publishing.

An example of a preprint server is the ‘arXiv’ developed by Paul Ginsparg in 1991, which is used primarily by physicists (). These alternative forms of peer review are still un-established and experimental. Traditional peer review is time-tested and still highly utilized. All methods of peer review have their advantages and deficiencies, and all are prone to error.

Open access (OA) journals are becoming increasingly popular as they allow the potential for widespread distribution of publications in a timely manner (). Nevertheless, there can be issues regarding the peer review process of open access journals. In a study published in Science in 2013, John Bohannon submitted 304 slightly different versions of a fictional scientific paper (written by a fake author, working out of a non-existent institution) to a selected group of OA journals.

  1. This study was performed in order to determine whether papers submitted to OA journals are properly reviewed before publication in comparison to subscription-based journals.
  2. The journals in this study were selected from the Directory of Open Access Journals (DOAJ) and Biall’s List, a list of journals which are potentially predatory, and all required a fee for publishing ().

Of the 304 journals, 157 accepted a fake paper, suggesting that acceptance was based on financial interest rather than the quality of article itself, while 98 journals promptly rejected the fakes (). Although this study highlights useful information on the problems associated with lower quality publishers that do not have an effective peer review system in place, the article also generalizes the study results to all OA journals, which can be detrimental to the general perception of OA journals.

  1. There were two limitations of the study that made it impossible to accurately determine the relationship between peer review and OA journals: 1) there was no control group (subscription-based journals), and 2) the fake papers were sent to a non-randomized selection of journals, resulting in bias.
  2. Based on a recent survey, the average acceptance rate for papers submitted to scientific journals is about 50% ().

Twenty percent of the submitted manuscripts that are not accepted are rejected prior to review, and 30% are rejected following review (). Of the 50% accepted, 41% are accepted with the condition of revision, while only 9% are accepted without the request for revision ().

Based on a recent survey by the PRC, 64% of academics are satisfied with the current system of peer review, and only 12% claimed to be ‘dissatisfied’ (). The large majority, 85%, agreed with the statement that ‘scientific communication is greatly helped by peer review’ (). There was a similarly high level of support (83%) for the idea that peer review ‘provides control in scientific communication’ ().

The following are ten tips on how to be an effective peer reviewer as indicated by Brian Lucey, an expert on the subject (): Peer review is a mutual responsibility among fellow scientists, and scientists are expected, as part of the academic community, to take part in peer review.

If one is to expect others to review their work, they should commit to reviewing the work of others as well, and put effort into it. If the paper is of low quality, suggest that it be rejected, but do not leave ad hominem comments. There is no benefit to being ruthless. When emailing a scientist to ask them to conduct a peer review, the majority of journals will provide a link to either accept or reject.

Do not respond to the email, respond to the link. Suggest how the authors can overcome the shortcomings in their paper. A review should guide the author on what is good and what needs work from the reviewer’s perspective. The peer reviewer plays the role of a scientific peer, not an editor for proofreading or decision-making.

  1. Don’t fill a review with comments on editorial and typographic issues.
  2. Instead, focus on adding value with scientific knowledge and commenting on the credibility of the research conducted and conclusions drawn.
  3. If the paper has a lot of typographical errors, suggest that it be professionally proof edited as part of the review.

Stick to the timeline given when conducting a peer review. Editors track who is reviewing what and when and will know if someone is late on completing a review. It is important to be timely both out of respect for the journal and the author, as well as to not develop a reputation of being late for review deadlines.

The peer reviewer must be realistic about the work presented, the changes they suggest and their role. Peer reviewers may set the bar too high for the paper they are editing by proposing changes that are too ambitious and editors must override them. Ensure that the review is scientific, helpful and courteous.

Be sensitive and respectful with word choice and tone in a review. Remember that both specialists and generalists can provide valuable insight when peer reviewing. Editors will try to get both specialised and general reviewers for any particular paper to allow for different perspectives.

  1. If someone is asked to review, the editor has determined they have a valid and useful role to play, even if the paper is not in their area of expertise.
  2. A review requires structure and logical flow.
  3. A reviewer should proofread their review before submitting it for structural, grammatical and spelling errors as well as for clarity.

Most publishers provide short guides on structuring a peer review on their website. Begin with an overview of the proposed improvements; then provide feedback on the paper structure, the quality of data sources and methods of investigation used, the logical flow of argument, and the validity of conclusions drawn.

Then provide feedback on style, voice and lexical concerns, with suggestions on how to improve. In addition, the American Physiology Society (APS) recommends in its Peer Review 101 Handout that peer reviewers should put themselves in both the editor’s and author’s shoes to ensure that they provide what both the editor and the author need and expect ().

To please the editor, the reviewer should ensure that the peer review is completed on time, and that it provides clear explanations to back up recommendations. To be helpful to the author, the reviewer must ensure that their feedback is constructive. It is suggested that the reviewer take time to think about the paper; they should read it once, wait at least a day, and then re-read it before writing the review ().

  1. The APS also suggests that Graduate students and researchers pay attention to how peer reviewers edit their work, as well as to what edits they find helpful, in order to learn how to peer review effectively ().
  2. Additionally, it is suggested that Graduate students practice reviewing by editing their peers’ papers and asking a faculty member for feedback on their efforts.

It is recommended that young scientists offer to peer review as often as possible in order to become skilled at the process (). The majority of students, fellows and trainees do not get formal training in peer review, but rather learn by observing their mentors.

According to the APS, one acquires experience through networking and referrals, and should therefore try to strengthen relationships with journal editors by offering to review manuscripts (). The APS also suggests that experienced reviewers provide constructive feedback to students and junior colleagues on their peer review efforts, and encourages them to peer review to demonstrate the importance of this process in improving science ().

The peer reviewer should only comment on areas of the manuscript that they are knowledgeable about (). If there is any section of the manuscript they feel they are not qualified to review, they should mention this in their comments and not provide further feedback on that section.

The peer reviewer is not permitted to share any part of the manuscript with a colleague (even if they may be more knowledgeable in the subject matter) without first obtaining permission from the editor (). If a peer reviewer comes across something they are unsure of in the paper, they can consult the literature to try and gain insight.

It is important for scientists to remember that if a paper can be improved by the expertise of one of their colleagues, the journal must be informed of the colleague’s help, and approval must be obtained for their colleague to read the protected document.

  • Additionally, the colleague must be identified in the confidential comments to the editor, in order to ensure that he/she is appropriately credited for any contributions ().
  • It is the job of the reviewer to make sure that the colleague assisting is aware of the confidentiality of the peer review process ().

Once the review is complete, the manuscript must be destroyed and cannot be saved electronically by the reviewers (). When performing a peer review, there are some common scientific errors to look out for. Most of these errors are violations of logic and common sense: these may include contradicting statements, unwarranted conclusions, suggestion of causation when there is only support for correlation, inappropriate extrapolation, circular reasoning, or pursuit of a trivial question ().

It is also common for authors to suggest that two variables are different because the effects of one variable are statistically significant while the effects of the other variable are not, rather than directly comparing the two variables (). Authors sometimes oversee a confounding variable and do not control for it, or forget to include important details on how their experiments were controlled or the physical state of the organisms studied ().

Another common fault is the author’s failure to define terms or use words with precision, as these practices can mislead readers (). Jargon and/or misused terms can be a serious problem in papers. Inaccurate statements about specific citations are also a common occurrence ().

Additionally, many studies produce knowledge that can be applied to areas of science outside the scope of the original study, therefore it is better for reviewers to look at the novelty of the idea, conclusions, data, and methodology, rather than scrutinize whether or not the paper answered the specific question at hand ().

Although it is important to recognize these points, when performing a review it is generally better practice for the peer reviewer to not focus on a checklist of things that could be wrong, but rather carefully identify the problems specific to each paper and continuously ask themselves if anything is missing ().

  • An extremely detailed description of how to conduct peer review effectively is presented in the paper How I Review an Original Scientific Article written by Frederic G.
  • Hoppin, Jr.
  • It can be accessed through the American Physiological Society website under the Peer Review Resources section.
  • A major criticism of peer review is that there is little evidence that the process actually works, that it is actually an effective screen for good quality scientific work, and that it actually improves the quality of scientific literature.

As a 2002 study published in the Journal of the American Medical Association concluded, ‘Editorial peer review, although widely used, is largely untested and its effects are uncertain’ (). Critics also argue that peer review is not effective at detecting errors.

Highlighting this point, an experiment by Godlee et al. published in the British Medical Journal (BMJ) inserted eight deliberate errors into a paper that was nearly ready for publication, and then sent the paper to 420 potential reviewers (). Of the 420 reviewers that received the paper, 221 (53%) responded, the average number of errors spotted by reviewers was two, no reviewer spotted more than five errors, and 35 reviewers (16%) did not spot any.

Another criticism of peer review is that the process is not conducted thoroughly by scientific conferences with the goal of obtaining large numbers of submitted papers. Such conferences often accept any paper sent in, regardless of its credibility or the prevalence of errors, because the more papers they accept, the more money they can make from author registration fees ().

This misconduct was exposed in 2014 by three MIT graduate students by the names of Jeremy Stribling, Dan Aguayo and Maxwell Krohn, who developed a simple computer program called SCIgen that generates nonsense papers and presents them as scientific papers (). Subsequently, a nonsense SCIgen paper submitted to a conference was promptly accepted.

Nature recently reported that French researcher Cyril Labbé discovered that sixteen SCIgen nonsense papers had been used by the German academic publisher Springer (). Over 100 nonsense papers generated by SCIgen were published by the US Institute of Electrical and Electronic Engineers (IEEE) ().

Both organisations have been working to remove the papers. Labbé developed a program to detect SCIgen papers and has made it freely available to ensure publishers and conference organizers do not accept nonsense work in the future. It is available at this link: (). Additionally, peer review is often criticized for being unable to accurately detect plagiarism.

However, many believe that detecting plagiarism cannot practically be included as a component of peer review. As explained by Alice Tuff, development manager at Sense About Science, ‘The vast majority of authors and reviewers think peer review should detect plagiarism (81%) but only a minority (38%) think it is capable.

The academic time involved in detecting plagiarism through peer review would cause the system to grind to a halt’ (). Publishing house Elsevier began developing electronic plagiarism tools with the help of journal editors in 2009 to help improve this issue (). It has also been argued that peer review has lowered research quality by limiting creativity amongst researchers.

Proponents of this view claim that peer review has repressed scientists from pursuing innovative research ideas and bold research questions that have the potential to make major advances and paradigm shifts in the field, as they believe that this work will likely be rejected by their peers upon review ().

Indeed, in some cases peer review may result in rejection of innovative research, as some studies may not seem particularly strong initially, yet may be capable of yielding very interesting and useful developments when examined under different circumstances, or in the light of new information (). Scientists that do not believe in peer review argue that the process stifles the development of ingenious ideas, and thus the release of fresh knowledge and new developments into the scientific community.

Another issue that peer review is criticized for, is that there are a limited number of people that are competent to conduct peer review compared to the vast number of papers that need reviewing. An enormous number of papers published (1.3 million papers in 23,750 journals in 2006), but the number of competent peer reviewers available could not have reviewed them all ().

Thus, people who lack the required expertise to analyze the quality of a research paper are conducting reviews, and weak papers are being accepted as a result. It is now possible to publish any paper in an obscure journal that claims to be peer-reviewed, though the paper or journal itself could be substandard ().

On a similar note, the US National Library of Medicine indexes 39 journals that specialize in alternative medicine, and though they all identify themselves as “peer-reviewed”, they rarely publish any high quality research (). This highlights the fact that peer review of more controversial or specialized work is typically performed by people who are interested and hold similar views or opinions as the author, which can cause bias in their review.

  • For instance, a paper on homeopathy is likely to be reviewed by fellow practicing homeopaths, and thus is likely to be accepted as credible, though other scientists may find the paper to be nonsense ().
  • In some cases, papers are initially published, but their credibility is challenged at a later date and they are subsequently retracted.

Retraction Watch is a website dedicated to revealing papers that have been retracted after publishing, potentially due to improper peer review (). Additionally, despite its many positive outcomes, peer review is also criticized for being a delay to the dissemination of new knowledge into the scientific community, and as an unpaid-activity that takes scientists’ time away from activities that they would otherwise prioritize, such as research and teaching, for which they are paid ().

As described by Eva Amsen, Outreach Director for F1000Research, peer review was originally developed as a means of helping editors choose which papers to publish when journals had to limit the number of papers they could print in one issue (). However, nowadays most journals are available online, either exclusively or in addition to print, and many journals have very limited printing runs ().

Since there are no longer page limits to journals, any good work can and should be published. Consequently, being selective for the purpose of saving space in a journal is no longer a valid excuse that peer reviewers can use to reject a paper (). However, some reviewers have used this excuse when they have personal ulterior motives, such as getting their own research published first.

  1. F1000Research was launched in January 2013 by Faculty of 1000 as an open access journal that immediately publishes papers (after an initial check to ensure that the paper is in fact produced by a scientist and has not been plagiarised), and then conducts transparent post-publication peer review ().
  2. F1000Research aims to prevent delays in new science reaching the academic community that are caused by prolonged publication times ().

It also aims to make peer reviewing more fair by eliminating any anonymity, which prevents reviewers from delaying the completion of a review so they can publish their own similar work first (). F1000Research offers completely open peer review, where everything is published, including the name of the reviewers, their review reports, and the editorial decision letters ().

  • PeerJ was founded by Jason Hoyt and Peter Binfield in June 2012 as an open access, peer reviewed scholarly journal for the Biological and Medical Sciences ().
  • PeerJ selects articles to publish based only on scientific and methodological soundness, not on subjective determinants of ‘impact ‘, ‘novelty’ or ‘interest’ ().

It works on a “lifetime publishing plan” model which charges scientists for publishing plans that give them lifetime rights to publish with PeerJ, rather than charging them per publication (). PeerJ also encourages open peer review, and authors are given the option to post the full peer review history of their submission with their published article ().

  1. PeerJ also offers a pre-print review service called PeerJ Pre-prints, in which paper drafts are reviewed before being sent to PeerJ to publish ().
  2. Rubriq is an independent peer review service designed by Shashi Mudunuri and Keith Collier to improve the peer review system ().
  3. Rubriq is intended to decrease redundancy in the peer review process so that the time lost in redundant reviewing can be put back into research ().

According to Keith Collier, over 15 million hours are lost each year to redundant peer review, as papers get rejected from one journal and are subsequently submitted to a less prestigious journal where they are reviewed again (). Authors often have to submit their manuscript to multiple journals, and are often rejected multiple times before they find the right match.

This process could take months or even years (). Rubriq makes peer review portable in order to help authors choose the journal that is best suited for their manuscript from the beginning, thus reducing the time before their paper is published (). Rubriq operates under an author-pay model, in which the author pays a fee and their manuscript undergoes double-blind peer review by three expert academic reviewers using a standardized scorecard ().

The majority of the author’s fee goes towards a reviewer honorarium (). The papers are also screened for plagiarism using iThenticate (). Once the manuscript has been reviewed by the three experts, the most appropriate journal for submission is determined based on the topic and quality of the paper ().

  • The paper is returned to the author in 1-2 weeks with the Rubriq Report ().
  • The author can then submit their paper to the suggested journal with the Rubriq Report attached.
  • The Rubriq Report will give the journal editors a much stronger incentive to consider the paper as it shows that three experts have recommended the paper to them ().

Rubriq also has its benefits for reviewers; the Rubriq scorecard gives structure to the peer review process, and thus makes it consistent and efficient, which decreases time and stress for the reviewer. Reviewers also receive feedback on their reviews and most significantly, they are compensated for their time ().

  1. Journals also benefit, as they receive pre-screened papers, reducing the number of papers sent to their own reviewers, which often end up rejected ().
  2. This can reduce reviewer fatigue, and allow only higher-quality articles to be sent to their peer reviewers ().
  3. According to Eva Amsen, peer review and scientific publishing are moving in a new direction, in which all papers will be posted online, and a post-publication peer review will take place that is independent of specific journal criteria and solely focused on improving paper quality ().

Journals will then choose papers that they find relevant based on the peer reviews and publish those papers as a collection (). In this process, peer review and individual journals are uncoupled (). In Keith Collier’s opinion, post-publication peer review is likely to become more prevalent as a complement to pre-publication peer review, but not as a replacement ().

  • Post-publication peer review will not serve to identify errors and fraud but will provide an additional measurement of impact ().
  • Collier also believes that as journals and publishers consolidate into larger systems, there will be stronger potential for “cascading” and shared peer review ().
  • Peer review has become fundamental in assisting editors in selecting credible, high quality, novel and interesting research papers to publish in scientific journals and to ensure the correction of any errors or issues present in submitted papers.

Though the peer review process still has some flaws and deficiencies, a more suitable screening method for scientific papers has not yet been proposed or developed. Researchers have begun and must continue to look for means of addressing the current issues with peer review to ensure that it is a full-proof system that ensures only quality research papers are released into the scientific community.1.

What is an example of scientific writing?

Three examples of scientific writing include journal articles, proposals, and review papers. While each of these utilizes scientific writing, they accomplish very different goals.

What are the five 5 characteristics of the scientific research?

TL;DR (Too Long; Didn’t Read) – Five key descriptors for the scientific method are: empirical, replicable, provisional, objective and systematic.

What are the 5 major parts of a scientific research article?

Scientific Papers Scientific papers are for sharing your own original research work with other scientists or for reviewing the research conducted by others. As such, they are critical to the evolution of modern science, in which the work of one scientist builds upon that of others.

  1. To reach their goal, papers must aim to inform, not impress.
  2. They must be highly readable — that is, clear, accurate, and concise.
  3. They are more likely to be cited by other scientists if they are helpful rather than cryptic or self-centered.
  4. Scientific papers typically have two audiences: first, the referees, who help the journal editor decide whether a paper is suitable for publication; and second, the journal readers themselves, who may be more or less knowledgeable about the topic addressed in the paper.

To be accepted by referees and cited by readers, papers must do more than simply present a chronological account of the research work. Rather, they must convince their audience that the research presented is important, valid, and relevant to other scientists in the same field.

The Introduction section clarifies the motivation for the work presented and prepares readers for the structure of the paper. The Materials and Methods section provides sufficient detail for other scientists to reproduce the experiments presented in the paper. In some journals, this information is placed in an appendix, because it is not what most readers want to know first. The Results and Discussion sections present and discuss the research results, respectively. They are often usefully combined into one section, however, because readers can seldom make sense of results alone without accompanying interpretation — they need to be told what the results mean. The Conclusion section presents the outcome of the work by interpreting the findings at a higher level of abstraction than the Discussion and by relating these findings to the motivation stated in the Introduction,

(Papers reporting something other than experiments, such as a new method or technology, typically have different sections in their body, but they include the same Introduction and Conclusion sections as described above.) Although the above structure reflects the progression of most research projects, effective papers typically break the chronology in at least three ways to present their content in the order in which the audience will most likely want to read it.

  1. First and foremost, they summarize the motivation for, and the outcome of, the work in an abstract, located before the Introduction,
  2. In a sense, they reveal the beginning and end of the story — briefly — before providing the full story.
  3. Second, they move the more detailed, less important parts of the body to the end of the paper in one or more appendices so that these parts do not stand in the readers’ way.

Finally, they structure the content in the body in theorem-proof fashion, stating first what readers must remember (for example, as the first sentence of a paragraph) and then presenting evidence to support this statement. : Scientific Papers
