Preprints: What They Are and Whether You Should Post One
A preprint is a version of a paper posted publicly, usually on a dedicated repository, before or during formal peer review. What used to be a niche practice mostly confined to physics and economics has spread widely across fields, and it’s worth understanding the actual trade-offs before deciding whether to post one, since the right choice varies considerably by field, career stage, and the specific nature of the work.
The main benefit is speed and priority
A preprint gets your work in front of the field immediately rather than waiting months for formal review, and it establishes a public, time-stamped record of when you had the result, directly relevant to the scooping concerns covered in our piece on IP ownership and scooping at conferences.
Check your target journal’s policy first
Most major journals now explicitly allow prior preprint posting, but not all do, and policies vary on specifics like whether the preprint needs to be updated or linked to the final published version. Confirming this before posting avoids a conflict discovered only at submission.
Preprints aren’t peer-reviewed, and that needs to stay clear
A preprint hasn’t been through the scrutiny that gives published work its credibility signal. Citing or building on someone else’s preprint means treating it with appropriately more caution than a peer-reviewed publication, and clearly labeling your own preprints as such avoids misleading readers about their status.
Sensitive or high-stakes findings deserve extra thought
Medical and clinical research in particular carries real risk if preliminary, unreviewed findings get picked up and acted on publicly before the result has been properly vetted. Fields with this kind of stakes generally treat preprinting more cautiously than fast-moving computational fields do.
Media and public communication around preprints require particular care
Journalists and the general public don’t always understand the distinction between a preprint and a peer-reviewed publication, which has occasionally led to premature or misleading media coverage of unreviewed findings. Researchers posting preprints on topics with genuine public interest should consider proactively clarifying the preliminary nature of the work in any public communication.
Preprint servers have proliferated, choosing the right one matters
Field-specific preprint servers, arXiv for physics and computer science, bioRxiv for biology, SSRN for social sciences, among others, have become the established norm in their respective fields. Posting to the recognized server for your field, rather than a generic or unfamiliar platform, maximizes visibility and credibility within your research community.
Posting one doesn’t replace formal submission
A preprint is a complement to, not a substitute for, going through peer review, most fields still weight the peer-reviewed, published version as the credential that actually counts for tenure, grants, and citation record.
A preprint decision checklist
- Target journal’s preprint policy confirmed before posting
- Field-specific, recognized preprint server selected, not a generic or unfamiliar platform
- Sensitive or high-stakes findings weighed with particular caution
- Public communication plan considered if the work has genuine media interest
- Preprint clearly labeled as unreviewed throughout any citation or discussion
Frequently asked questions
Can I update a preprint after posting it?
Yes, most preprint servers allow versioned updates, worth doing if the work evolves significantly before or during formal peer review.
Does posting a preprint count as prior publication that would prevent later journal submission?
Generally no, for journals that explicitly allow it, though always confirm the specific target journal’s policy rather than assuming universally.
Are preprints citable in a formal academic context?
Yes, with appropriate caveats about their unreviewed status, most citation styles now have established conventions for citing preprints distinctly from peer-reviewed publications.
