Between 2015 and 2017, most submissions to Nature's family of journals never reached a peer reviewer.

Rejection before review is routine in academic publishing, and the letter that delivers it may run only a few lines. It may name scope or priority as the reason, or give no reason at all. Authors are left to guess what went wrong, and the same manuscript can go to the next journal with the same weaknesses.

One way to prepare for this stage is to treat the editor as the first reviewer. That means learning what editors screen for, confirming the journal is the right one, and fixing the paper's core argument before polishing its format.

Below are the reasons editors decline papers early, what they read to decide, and the checks worth running before you submit.

What Desk Rejection Is and How It Differs From Post-Review Rejection

A desk rejection is a journal editor's decision to decline a manuscript without sending it to external peer reviewers. The editor, sometimes with advice from colleagues, judges whether the paper fits the journal and merits reviewers' time. A post-review rejection comes later, after referees have assessed the methods, results, and conclusions in detail.

Desk decisions are common and quick. Across 25 Nature-branded journals, 77% of single-blind submissions and 92% of double-blind submissions were rejected without review between March 2015 and February 2017. At JAMA, the median time to a first decision is 2 days without external review, compared with 24 days with review.

The two outcomes also differ in what authors learn. A post-review rejection usually arrives with referee reports that name specific problems. A rejection from the editor may give only a short reason, such as scope or priority, with no detail on the science.

Editors also disagree with each other. When three co-editors-in-chief at the International Journal of Public Health independently screened the first 30 submissions one of them handled in November 2024, they fully agreed on only 43% of them. Agreement rose to 67% after they considered second opinions. The sample is small and comes from one journal, and it suggests that the decision to reject before review depends partly on which editor reads the paper.

The Reasons Editors Reject Papers Before Sending Them for Review

Detailed data on early rejection comes from a journal that coded its own decisions. Editors at Academic Medicine, a medical education journal, analyzed 369 manuscripts submitted between December 2014 and December 2015 and rejected before external review. Manuscripts had, on average, three or more reasons for rejection.

A Research Question or Design That Cannot Deliver

Editors cited an ineffective study question or design in 92% of rejected manuscripts. The question may be too broad, already answered, or unanswerable with the design chosen. In a life science paper, a comparable concern could arise from using a single cell line to support a claim about a whole tissue, or from a knockdown without a rescue experiment.

Weak Data Collection and Analysis

Suboptimal data collection appeared in 49% of the same rejections, and weak analysis or presentation of results in 33%. This group includes underpowered samples, missing controls, and unclear statistical methods. An editor who cannot see how the data support the conclusions has little reason to ask reviewers to look.

A Topic Outside the Journal's Mission

The editors cited an unimportant topic, or one irrelevant to the journal's mission, in 37% of cases. A sound study can fail this test when its question matters to a different readership. Scope pages describe each journal's readership, and editors hold submissions to that audience.

Reporting, Ethics, and Language Gaps

Other rejections come from the screening checks journals run before review. PLOS ONE's editor-in-chief reported in 2021 that the journal rejects around 20% of submissions without review, after checks on scope, methods detail, language quality, and whether the research meets high ethical standards. Academic Medicine's editors also cited difficult-to-follow text in 24% of their early rejections.

What Editors Actually Read When Making a Desk Rejection Decision

Journals describe the editor's question in plain terms. Nature sends papers for review when the results seem "novel, arresting" and the work has immediate and far-reaching implications, and it usually tells authors within a week if a paper is not being considered. In PLOS Computational Biology, Mensh and Kording write that editors want to make sure a paper is significant, while reviewers judge whether the conclusions are justified. Each part of the manuscript feeds that decision.

• Cover letter: The letter should tell the editor why the result matters to this journal's readers. A letter that restates the abstract gives the editor little reason to send the paper for review.
• Title and abstract: The abstract should state the central claim and the main evidence behind it. An abstract that describes what was studied without saying what was found makes significance hard to judge.
• Research question and design: The editor checks whether the design can answer the question. In the Academic Medicine data, this was the most frequently cited problem.
• Methods and results: The editor looks for conclusions that go further than the data. Nature Medicine lists the extent to which the evidence supports the conclusions among the factors editors weigh when deciding whether to send a paper for review.
• Compliance items: Ethics approvals, trial registration, data availability statements, and reporting checklists are checked at submission. A missing item can stop a manuscript before anyone assesses the science.

How to Assess Journal Fit Before You Submit

Pre-review rejection rates vary widely between journals. Parasites & Vectors, a parasitology journal, reported a pre-review rejection rate of 39% in 2022, compared with about 20% at PLOS ONE in 2021 and 77% to 92% across Nature-branded journals in 2015 to 2017. The checks below help confirm fit before any journal submission.

A journal can pass every check and still decline a paper on priority. Fit checks reduce avoidable scope rejections, and the rest depends on the manuscript.

How to Reduce Desk Rejection Risk in Your Submission

The fixes for early rejection belong in manuscript preparation, well before the cover letter. These steps target the triggers covered above and prepare your next move if the first journal declines.

• State the central claim early: Put the main finding and its key evidence in the first lines of the abstract, where an editor can judge significance quickly.
• Test the design against the question: List each claim in the paper and the experiment that supports it. A claim without direct support needs a new experiment, narrower wording, or removal.
• Match conclusions to the evidence: Check that the abstract and discussion claim no more than the results show in scope, population, and certainty.
• Run the reporting checklist: Use the guideline for your study design from the EQUATOR Network, such as CONSORT for trials or ARRIVE for animal research. For clinical trials, confirm registration, because trials not registered prospectively risk inadmissibility at ICMJE member journals.
• Write a cover letter that argues fit: Name the journal's readership, explain why the result matters to them, and point to related work the journal has published.
• Plan the next journal before you submit: Rank two or three journals in advance. A study of three elite medical journals found that editors generally made good decisions, yet the journals had rejected the 14 most-cited of 808 eventually published manuscripts, 12 of them at the desk.

Find the Weak Claims Before You Submit

Editors ask whether a paper's claims matter, and reviewers ask whether the evidence supports them. Authors can ask both questions of their own manuscript before submitting, while they still have time to add an experiment or narrow a claim.

QED Science's Paper Review is built for the step before submission. It breaks a manuscript into its core claims, evaluates the evidence behind each one against the existing literature, and surfaces the gaps a reviewer would catch, with specific recommended fixes. The work runs as an author-controlled review that keeps the manuscript private, and the report stays in your account.

The same claim-level approach underlies QED Score, a validated quality metric for originality and validity that separated weaker from stronger papers with an AUC of 0.867 on a 925-paper, expert-labeled set of life-science manuscripts.
