What is Peer Review? Double-Blind Review in an Engineering Journal Explained

What is Peer Review? Double-Blind Review in an Engineering Journal Explained

Peer review is the process where independent experts assess a manuscript before an engineering journal publishes it. In double-blind review the reviewers do not know who wrote the paper, and the authors never learn who reviewed it. At this journal every submission goes to a subject editor first, then to two reviewers, and the Subject Editor takes the final decision.

Most authors meet engineering journal peer review for the first time when their own paper is in it, which is a stressful way to learn how it works. This guide sets out what actually happens, what reviewers are looking for, and why so many papers fail on the same few points.

The three models you will meet

ModelAuthor knows reviewer?Reviewer knows author?
Single-blindNoYes
Double-blind (used here)NoNo
OpenYesYes

Double-blind exists to remove a specific problem: reviewers unconsciously judging a paper by the reputation of the institution on the front page. It is not perfect — a reviewer who knows the field well can often guess the group from the methods or the self-citations — but it removes the easiest form of bias, and it protects early-career authors most.

What happens to your paper, step by step

  1. Editorial check. The subject editor reads the manuscript against editorial policy and a minimum quality level. Scope mismatches and incomplete submissions stop here.
  2. Anonymisation. Identifying information is stripped from the document.
  3. Two reviewers. The paper goes out to two independent reviewers.
  4. Reports come back. Comments are made anonymous before being sent to the corresponding author.
  5. Revision. You return the revised manuscript within one week.
  6. Second look. The revision goes back to the reviewers.
  7. Decision. The Subject Editor decides.

Reviewers’ comments to the editors are confidential. What reaches you is the anonymised version, together with the decision.

What reviewers are actually assessing

Reviewers are not hunting for reasons to reject. They are answering one question: can I tell exactly what was done, and do the results support the conclusion? Almost every negative report traces back to one of these:

  • Method too thin to judge. No replication count, no design named, no control, statistics without a significance level.
  • Results that argue. Results state what happened, in the past tense, without references. Interpretation belongs in the Discussion.
  • Conclusions ahead of the data. A single-site, single-season result recommended for regional adoption.
  • Missing material identity. The alloy grade, the software version, the sensor model — unnamed, so nobody can repeat it.
  • Unreadable methods. If two readings give two different experiments, the reviewer has to guess, and guessing resolves against you.
None of these need more experiments. They need you to write down what you already did.

Anonymising your own manuscript

Double-blind only works if you help. Before submitting, remove your name and affiliation from the body, check the acknowledgements do not identify your group, and look at the file properties — Word stores the author name in the document metadata, which authors forget almost every time.

Self-citation is the other giveaway. “As we showed in our earlier work [7]” identifies you immediately. Write “an earlier study [7] showed” instead. You still get the citation; you just do not sign it.

How long it takes, and what you control

Review at an engineering journal takes as long as it takes — reviewers are working researchers doing this unpaid. What you control is your own turnaround. The revision window here is one week, and the single biggest delay in most published papers is an author sitting on reviewer comments for a month.

Our guide on responding to reviewer comments shows the response format that gets papers through the second round quickly.

What a reviewer report actually looks like

Reports from an engineering journal vary, but most arrive as a recommendation plus a numbered list of comments. The recommendation is one of four:

DecisionWhat it meansWhat to do
AcceptRare on a first submissionCheck the proof carefully
Minor revisionThe science stands; clarify and tidyUsually a few days of work
Major revisionSomething substantive is unresolvedAnswer every point; this is not a rejection
RejectThe objection cannot be fixed by rewritingRead which stage rejected you

“Major revision” frightens authors more than it should. It means the reviewers think the work is worth publishing once a real problem is addressed. Papers are lost at this stage far more often through a weak response than through a weak result.

Three myths about peer review at engineering journals

Myth 1: reviewers are trying to protect their own work

Reviewers are researchers in your field, which is exactly why they were asked. A reviewer who genuinely has a conflict is supposed to decline. In practice the far commoner problem is the opposite — a reviewer who knows the area so well that they assume detail you never wrote down, and then ask for it.

Myth 2: a fast decision means the journal did not review the paper

Speed depends on how quickly two busy people reply, not on how carefully they read. A paper can clear review in three weeks because both reviewers happened to be free. What should worry you is a journal promising a fixed turnaround before it has seen your manuscript — nobody can commit to that honestly.

Myth 3: peer review checks whether the results are true

It does not, and cannot. Two people reading a document cannot rerun your experiment. Review checks whether the work is reported well enough that someone else could rerun it, and whether the conclusions follow from what you reported. That is a narrower job than most people assume, and it is why replication still matters after publication.

What happens alongside review

Two checks run in parallel with the reviewers’ reading, and both can stop a paper on their own:

  • Similarity screening. Every submission is checked for text overlap. Plagiarism found before or after publication leads to the paper being retracted and the authors blacklisted. Self-plagiarism counts — reusing your own methods paragraph verbatim registers just the same, so cite the earlier paper instead of repeating it.
  • Formatting check. Manuscripts outside the specification go back before review. The limits are short: MS Word, not more than 15 pages, abstract not more than 300 words, 3 to 6 keywords, Vancouver references, figures at 300 dpi. All of it is on the Instructions to Author page.

How to make a reviewer’s job easy

Every minute a reviewer spends working out what you meant is a minute not spent on your findings, and confusion resolves against the author. Four habits do most of the work:

  1. Name the design and the replication in one sentence. Not "experiments were conducted" but "a randomised block design with four replications".
  2. Put units and significance on every number that matters. "Yield rose 22.2% (p < 0.01)" ends an argument that "yield rose significantly" starts.
  3. Keep the Results section factual. Past tense, no citations, no interpretation.
  4. Have a colleague who did not do the work read your Methods and describe the experiment back to you. Every point where their description differs is a sentence to rewrite.

Peer review is not a guarantee, and not a formality

Two things get said about peer review, and both are wrong. Peer review at an engineering journal is not a guarantee of correctness — two people reading a manuscript cannot replicate your experiment, and errors do get through. It is also not a rubber stamp: a journal that publishes whatever arrives is not running review at all, whatever its website says.

What you should check before submitting anywhere is whether the process is described at all. This journal sets it out on the peer review and publication policy page: initial editorial read, two reviewers, double-blind, Subject Editor decides. An engineering journal that cannot describe its own process in a paragraph is telling you something.

Frequently asked questions

What does double-blind peer review mean?

Neither side knows who the other is. Your name, affiliation and contact details are stripped from the manuscript before it goes to reviewers, and their identities are never disclosed to you. The point is that the paper is judged on what it says, not on where it came from.

How many reviewers will read my paper?

Two. Before that, the subject editor reads it once to check it fits editorial policy and meets a minimum quality level. Papers that fail that first check never reach reviewers.

Can I suggest reviewers for my own paper?

You may name two potential reviewers in your cover letter, with their contact details and affiliation. It is optional, and the editor is not obliged to use them. Suggesting people who cannot possibly be objective — your supervisor, a co-author — wastes the opportunity.

What are reviewers actually asked to judge?

Whether the work is original, whether the method is described well enough to be evaluated and repeated, whether the results support the conclusions, and whether the reporting is complete. Writing quality matters only where it stops them understanding what was done.

Who makes the final decision?

The Subject Editor, based on both reviewers' reports. Where substantial revisions were requested, acceptance depends on whether you have dealt with them satisfactorily.
