Why Manuscripts Get Rejected (and How to Avoid It)

Most rejections aren't about the underlying research being bad — they're about avoidable, fixable issues in how it's presented, scoped, or targeted.

Desk rejection reasons (before peer review)

• Poor journal fit — submitting outside the journal's scope or aims.
• Missing reporting standards — no PRISMA checklist for a systematic review, no CONSORT for a trial, when the journal requires them.
• Weak or generic cover letter that doesn't state the paper's significance.
• Formatting non-compliance — word count, reference style, or structure that ignores author guidelines.

Rejection after peer review

• Methodological weaknesses — inadequate sample size, inappropriate statistical test, unaddressed confounders.
• Overclaiming — conclusions that go beyond what the data actually supports.
• Insufficient novelty — the contribution isn't clearly distinguished from existing literature.
• Unclear or incomplete methods — reviewers can't assess validity if they can't follow exactly what was done.

How to reduce your rejection risk

• Read the journal's recent issues, not just its aims and scope page, before submitting.
• Follow the relevant reporting checklist exactly (PRISMA, CONSORT, STROBE, etc.).
• Have someone outside your immediate team read the manuscript for clarity gaps you can no longer see.
• Be explicit about limitations rather than letting a reviewer find them first.

A rejection with reviewer comments is not the end — see our guide on responding to journal reviewers for how to turn feedback into a stronger resubmission, at this or another journal.
