Is PLOS ONE a Good Journal? Predatory or Legitimate?

PLOS ONE is strongest when the manuscript does three things well: asks a clear scientific question, answers that question with sound methods, and doesn't depend on a high-prestige editorial filter to justify publication.

That makes the journal especially useful for:

• Solid confirmatory or incremental work that deserves a citable home
• Negative or null results with real methodological value
• Replication studies
• Interdisciplinary papers that don't fit cleanly into one prestige-driven journal hierarchy
• Work where open-access availability matters more than journal signaling

The key distinction is that PLOS ONE screens for scientific soundness, not editorial excitement.

This is the part many authors misunderstand. PLOS ONE reviewers are generally not being asked whether the paper is flashy enough or likely to attract broad attention. They are being asked whether:

• The methods are appropriate
• The analysis is credible
• The conclusions are supported
• The work meets basic reporting and ethical standards

That doesn't mean the review is trivial. It means the filter is different.

For some papers, this is a genuine advantage. A careful null result or replication study may be scientifically valuable while still struggling at significance-driven journals. PLOS ONE can be the more honest venue for that work.

For other papers, the model removes the exact signaling the authors actually need. If the career value of the paper depends heavily on editorial selectivity, PLOS ONE may not deliver the right kind of outcome even when the paper is perfectly publishable.

In our pre-submission review work with manuscripts targeting PLOS ONE, we see three failure patterns that the journal's soundness-only label masks.

The methods section that assumes soundness-review means lenient review. This sinks more PLOS ONE submissions than authors expect. We find that roughly 35% of the manuscripts we review for PLOS ONE have methods sections that wouldn't pass a strict specialist journal either, but the authors assumed PLOS ONE would be less rigorous. In practice, PLOS ONE editors and reviewers enforce methodological standards seriously. Underpowered studies, missing controls, and statistical approaches that don't match the study design get desk-rejected or rejected in review just as they would at more selective venues.

The introduction that oversells significance to a journal that doesn't care. We notice this pattern in roughly 25% of PLOS ONE-targeted manuscripts. The authors frame the paper as if they're pitching to a novelty-filtered journal: sweeping claims about how the work will "advance our understanding" or "fill a critical gap." PLOS ONE editors actually respond better to proportionate framing: "this is a methodologically rigorous study that contributes to the evidence base" rather than "this study will transform the field." The overselling reads as misaligned to the journal's identity.

The scope mismatch that the author doesn't recognize. According to PLOS editorial data, scope accounts for a significant portion of desk rejections. We see manuscripts submitted to PLOS ONE that are really engineering papers, or social science papers, or humanities papers with a thin science angle. PLOS ONE covers all natural sciences but draws clear lines around its scope. Papers where the primary contribution is a software tool, a policy recommendation, or a pedagogical intervention often don't fit, even if they involve data analysis.

Before submitting, a PLOS ONE scope check identifies whether the paper is in scope and whether the methods section meets the rigor PLOS ONE actually enforces before an editor flags it.

PLOS ONE's scale creates some documented issues that authors should know about:

• Peer review manipulation. PLOS ONE has retracted 100+ articles for peer review manipulation, including cases where authors suggested fake reviewers. Per Retraction Watch data, this is proportional to the journal's massive volume but still worth noting.
• Editorial consistency. SciRev community data shows mixed experiences with editorial responsiveness. Some authors report smooth, fast processes; others report months of silence followed by contradictory reviewer requests.
• Retraction rate. PLOS ONE's retraction rate tracks slightly above the field average, which is partly a function of volume and partly a function of the journal's willingness to retract (some journals are more reluctant to retract, which isn't better).

None of these make PLOS ONE predatory. They reflect the operational challenges of running a journal that publishes 25,000 articles per year.

PLOS ONE is often the right call when the study is rigorous and deserves a durable literature record, the paper includes null or confirmatory results that matter scientifically, the work benefits from open availability and broad discoverability, and the authors value a legitimate, established venue over prestige theater.

Another journal is often the smarter decision when the paper has a clearer audience inside one field than across science broadly, the authors still have a realistic chance at a stronger specialist venue, the paper's next use depends on stronger brand or status signaling, or the manuscript would gain more citations from being placed inside its natural journal ecosystem.

The right question isn't only "is PLOS ONE good?" It's "good for what?"
