Scientific Reports Cover Letter: What Editors Actually Need to See
Scientific Reports evaluates technical merit, not perceived impact. A cover letter that argues for novelty is written for the wrong journal. Argue for rigor instead.

Quick answer: Scientific Reports evaluates technical merit, not perceived impact. A strong cover letter argues for methodological rigor and reproducibility. If your letter spends three paragraphs on why the finding is novel, it is written for the wrong journal.
What the official sources do and do not tell you
The Scientific Reports author guidelines explain submission requirements and the Nature Portfolio review process. They do not spell out how dramatically the evaluation criteria differ from other Nature Portfolio journals.
What the editorial model implies:
- reviewers assess technical soundness, methodological rigor, data quality, and reproducibility
- reviewers do not assess novelty, significance, or expected impact
- no presubmission inquiry is accepted — you submit directly
- the ~50% acceptance rate is higher than most Nature Portfolio journals, but papers with genuine methodological problems are still rejected
What the editor is really screening for
At triage, the editor is asking:
- are the methods detailed enough for another group to replicate this work?
- do the conclusions actually match the data presented?
- is the study within the journal's scope (natural sciences, with empirical validation)?
- is the data availability statement concrete?
Arguing that your finding is "the first to show X" does not help here. Confirming that your methods are replicable does.
What a strong Scientific Reports cover letter should actually do
A strong letter usually does four things:
- states what was studied and what was found (one to two sentences, no hedging)
- confirms the methods are detailed enough for replication and names any data repositories
- confirms the conclusions are limited to what the data supports
- confirms scope fit in one sentence
Keep it under one page. The editor is handling enormous submission volume.
A practical template you can adapt
Dear Editor,
We submit "[TITLE]" for consideration as an Article in Scientific
Reports.
[1–2 sentences: what the study investigated and what was found.
Active voice, specific.]
[1–2 sentences: study design, sample size, and key methods.
Mention data or code repositories if applicable.]
Our conclusions are limited to what the data supports. This work
falls within the scope of Scientific Reports as an original
investigation in [field].
All authors have approved the manuscript. We confirm no competing
interests. [Data availability / ethics approval if applicable.]
Sincerely,
[Name, Affiliation]Mistakes that make these letters weak
The common failures are:
- arguing novelty instead of rigor (the journal does not evaluate novelty)
- vague methods descriptions ("standard protocols," "methods as previously described")
- missing data availability statements
- overclaiming in conclusions ("demonstrate" when the data show a correlation)
- skipping the cover letter entirely because it is not strictly required
What should drive the submission decision instead
Before polishing the letter further, confirm the journal fit is honest.
The better next reads are:
- Scientific Reports acceptance rate
- Scientific Reports submission guide
- Scientific Reports vs PLOS ONE
If the work has broader significance, Nature Communications or a field-specific Nature journal may be the reach target. PLOS ONE uses a similar technical-merit model with comparable acceptance rates.
Practical verdict
The strongest Scientific Reports cover letters are short and rigor-focused. They state the finding, confirm replicable methods, and avoid the novelty arguments that belong at other Nature Portfolio journals.
