Open peer review has emerged as a transformative practice in scholarly publishing, challenging the long-standing tradition of anonymity that has defined peer review for centuries. In engineering disciplines, where research often underpins critical infrastructure, safety systems, and technological innovation, the transparency afforded by open peer review carries particular weight. By making reviewer identities known and publishing review reports alongside articles, this approach aims to increase accountability, enhance the quality of feedback, and build greater trust in the validation process. This article examines the impact of open peer review on both author and reviewer transparency in engineering, exploring its benefits, challenges, and potential for reshaping scholarly communication in the field.

What Is Open Peer Review?

Open peer review is not a single, monolithic model but rather a spectrum of practices that move away from the traditional double-blind or single-blind review. The core components often include:

  • Identified reviewers: Reviewers sign their comments so authors know who provided the feedback.
  • Published review reports: The full exchange of reviews and author responses is made publicly available alongside the published article.
  • Open participation: In some models, a broader community beyond invited reviewers can contribute comments.
  • Preprint sharing: Manuscripts are posted publicly before formal review, inviting open commentary from the onset.

While practices vary among journals, the unifying theme is a move toward transparency. In contrast to the sealed black box of traditional review, open peer review exposes the process to scrutiny, which advocates argue leads to more careful, constructive, and objective evaluations.

The Landscape of Peer Review in Engineering

Engineering research spans a vast array of subfields—from civil and mechanical engineering to electrical, chemical, biomedical, and software engineering. The peer review culture in engineering has historically favored double-blind review, especially in top journals such as those published by IEEE, ASME, and ASCE. This preference stems from a desire to minimize bias based on author reputation, institution, or geographic origin. However, concerns about the effectiveness of blinding (especially in small, specialized communities) and the need for greater openness in the face of reproducibility crises and data sharing challenges have prompted many engineering journals to experiment with or adopt open peer review.

Early adopters in engineering and applied sciences include journals from organizations like PLOS ONE, F1000Research, and some IEEE titles that have piloted open peer review schemes. The Committee on Publication Ethics (COPE) has also issued guidelines that encourage transparency without mandating a specific model. As more engineering journals consider shifting away from traditional anonymous review, understanding the effects on authors and reviewers becomes critical.

Impact on Author Transparency

Open peer review fundamentally alters the relationship between authors and the evaluation process. When reviewer identities are disclosed, authors can contextualize feedback within the reviewer’s known expertise and potential biases. This can lead to clearer, more direct communication. For example, an author receiving a critical point from a well-known expert in the same subfield can immediately gauge the weight of the criticism and respond accordingly, without the ambiguity of an anonymous critique.

Clearer Feedback and Better Understanding

Under traditional anonymous review, authors sometimes face cryptic or overly brief comments. With open review, reviewers are often more measured and thorough because their names are attached. A study published in Nature Communications found that open peer review led to longer, more substantive reviews and that authors rated the helpfulness of reviews higher. For engineers, where experimental details and numerical accuracy are paramount, such detailed feedback can catch methodological flaws earlier and improve the final manuscript.

Increased Trust in the Review Process

Authors who can see the entire review history—including how reviewers’ comments evolved and how editors made decisions—gain confidence that the process is fair and rigorous. This transparency can reduce feelings of unfair rejection or bias, encouraging more submissions to journals with open practices. Trust is especially vital in engineering, where published research may directly influence design standards, safety regulations, or patent filing.

Motivation for Higher Quality Research

The prospect of having one’s work and the associated reviews visible to the public may motivate authors to polish their manuscripts more carefully. Knowing that future employers, funding agencies, or reviewers of conference presentations might see not just the final version but also the peer review comments can incentivize authors to provide stronger evidence, clearer methodology, and more thorough data sharing. A survey of authors publishing in open peer review journals indicated that a majority felt the process encouraged them to produce better work.

Potential Drawbacks for Authors

Despite these advantages, some authors express concern about career repercussions. If a manuscript is rejected after open review, the negative comments (even if invalidated by later findings) could remain publicly associated with the author’s name. Junior researchers or those from underrepresented groups might be particularly vulnerable. To mitigate this, some journals allow authors to opt out of open review or to delay the publication of review reports.

Impact on Reviewer Transparency

For reviewers, open peer review shifts the dynamic from a purely altruistic, behind-the-scenes activity to a visible scholarly contribution. This change brings both opportunities and challenges.

Public Recognition and Career Benefits

When reviewers are named, their contributions become citable and can be listed on resumes or academic profiles. Some journals now publish reviewer reports as citable items, and platforms like Publons (now part of Web of Science) have integrated with open review systems to track reviewer contributions. For engineers, who may struggle to gain recognition for peer review in a field where it is often undervalued relative to research or teaching, this visibility can be a powerful motivator.

Accountability and Thoroughness

Knowing that their name will appear alongside their comments encourages reviewers to be more careful, objective, and constructive. The risk of reputational damage from giving a sloppy or biased review can outweigh the effort required to produce a careful evaluation. Data from open peer review implementations show that reviews tend to be longer, more polite, and more likely to include recommendations for improvement. In engineering, where methodological precision is key, this accountability reduces the chance of overlooking serious flaws or making unjustified demands.

Contribution to Scientific Integrity

Open peer review allows the broader community to evaluate not just the research but also the review itself. If a reviewer makes an error or demonstrates bias, it becomes visible. This collective oversight can strengthen the self-correcting nature of science. For example, in a case where a reviewer demands a standard test that is inappropriate for a new material, the author can publicly point this out, and the editor’s decision can be better understood. The entire process becomes a dialog that can be referenced by other researchers facing similar issues.

Challenges for Reviewers

On the downside, open peer review may discourage some qualified individuals from reviewing. They might fear retaliation from authors, especially in small specialty areas of engineering where relationships are close. Others may worry about exposing their reviewing style or the time they spend—some reviewers prefer to remain anonymous to avoid being pestered for future reviews. There is also the risk that published reviews could be used by lawyers in patent litigation or by competitors. Journals often address these concerns by offering a hybrid model where the reviewer can choose to remain anonymous, or by publishing the review report without the reviewer’s name.

The central tension in open peer review is between the benefits of transparency and the potential chilling effect on candid feedback. In engineering, where research may be commercially sensitive or where strong opinions can exist about design choices, this balance is particularly delicate.

Hybrid and Multi-Stage Models

Many engineering journals that have adopted open peer review use hybrid models. Some typical approaches include:

  • Optional openness: Reviewers can choose to sign or remain anonymous; authors may also opt to keep review reports private.
  • Transparent peer review with anonymous reviewers: The review reports are published, but reviewer names are omitted. This gives visibility to the process while protecting reviewer identity.
  • Open identities after acceptance: Reviewer names are revealed only after the paper is published, reducing retaliation risk during the review stage.
  • Limited-time openness: Review reports are published for a set period (e.g., one year) and then removed.

These models allow engineering journals to experiment with openness while maintaining the safeguards that reviewers and authors have come to expect.

Evidence from Engineering Journals

The American Society of Mechanical Engineers (ASME) conducted a pilot of open peer review in one of its journals. Results indicated that participation rates remained high, and authors reported a more positive perception of the review process. Similarly, the IEEE Transactions on Professional Communication experimented with open review in a special issue, finding that the quality of comments improved without a decline in willingness to review. These case studies suggest that open peer review can be successfully implemented in engineering, provided that clear guidelines and opt-out options are available.

Concerns and Criticisms

Despite the promising evidence, open peer review is not without detractors. Critics point out that disclosure of reviewer identity can lead to social desirability bias, where reviewers are hesitant to reject a paper from a well-known author or to point out serious flaws for fear of backlash. In small engineering subfields dominated by a few key labs, this could undermine the rigor of review.

Another concern is the burden on early-career reviewers. Junior researchers may feel pressure to accept review invitations when their name will be attached, even if they lack the bandwidth or confidence. This can lead to overwork and lower-quality reviews. Conversely, some senior researchers might refuse to review under open identity, reducing the pool of expertise for editors to draw upon.

Finally, legal and ethical issues arise if published review reports contain confidential data or disputable claims. Journals must have clear policies on retraction or correction of reviews, and authors must agree to the publication of the review record as a condition of submission. The COPE guidelines on peer review provide a useful framework for balancing these interests.

Conclusion

Open peer review in engineering represents a significant step toward greater transparency and accountability in scholarly communication. By making reviewer identities visible and review reports public, the model encourages clearer feedback, motivates higher-quality research, and builds trust in the evaluation process. For authors, it offers a window into the decision-making behind editorial outcomes; for reviewers, it provides recognition and a tangible contribution to the scholarly record.

However, the implementation of open peer review must be handled thoughtfully, with attention to the specific norms and sensitivities of engineering disciplines. Hybrid models that allow for anonymity when needed, coupled with clear editorial policies, can help mitigate concerns about bias, career risk, and legal exposure. As more engineering journals pilot and adopt open peer review—and as studies continue to assess its effects—the field is likely to see a gradual but meaningful shift toward a more transparent review culture. Ultimately, the success of open peer review will rest on its ability to preserve the rigor that engineering research demands while opening the process to the scrutiny that modern science expects.
