Types of peer review for scientific articles: what's the difference?

Peer review plays a crucial role in the process of publishing scientific research, determining whether an article will be published in a journal. The choice of the format of this assessment affects both the level of anonymity of the participants and the analysis methodology used. In this article, we will look at the main types of peer review, their key characteristics, as well as their advantages and limitations.

What is peer review, and why is it important?

Peer review – is the process of evaluating a scientific article by independent experts before its publication. It helps to ensure the quality, reliability, and novelty of the research.

Depending on the level of anonymity of the participants in this process, there are several main types of peer review, which we will consider below.

Main types of peer review

1. Single-blind peer review

Single-blind peer review means that the reviewer knows the identity of the author of the article, while the researcher does not know who is evaluating the work. This format allows the reviewer to freely express an opinion while remaining anonymous.

However, knowing the author's identity can lead to subjectivity, especially if the reviewer is familiar with the author or his reputation in the scientific community, which sometimes causes controversy.

2. Double-blind peer review

Here, the identities of the author and reviewer are hidden from each other. This method is considered one of the most objective, since it excludes the influence of reputation or personal connections. However, in highly specialized fields, anonymity can be conditional due to the fact that the writing style or the topic of the research can give away the author.

3. Triple-blind peer review

It is worth noting that before the reviewer receives the article for evaluation, its distribution is handled by the editor. In order to eliminate any conflicts of interest and guarantee objectivity, triple-blind peer review is used. The difference between this approach and double-blind peer review is not only the anonymity of the reviewer and the author, but also the anonymity of the editor.

However, this approach is difficult to implement, especially in narrow scientific circles where participants can guess each other's identities.

4. Open peer review

In open peer review, the names of the author and reviewer are known to both parties, and in some cases, review reports are published along with the articles. This approach increases the transparency of the evaluation process and increases the sense of accountability among reviewers.

However, openness may inhibit critical comments due to concerns about causing conflicts or affecting professional relationships.

5. Post-publication review

Of all the above-mentioned types of review, post-publication review has the most unconventional approach. This method involves evaluating an article after its publication.

Readers and experts can leave reviews on the journal's online platform, which allows for a variety of opinions to be collected. However, the quality of such reviews may be uneven, as they are not always from qualified professionals.
