Frontiers Journals — Quality or Questionable? What Researchers Say

Few open-access publishers divide opinion as sharply as Frontiers Media. Some senior researchers treat it as a legitimate venue they cite and submit to without hesitation. Others treat it as one step away from predatory — indexed, yes, but with review standards they consider too light to count. The question "are Frontiers journals legitimate" comes up in almost every journal-selection conversation we have.

The honest answer is complicated, and this post tries to deliver that honesty without landing in either camp. Frontiers is a real publisher running real peer review, with indexed journals and a COPE-compliant infrastructure. It also has a documented pattern of high-profile retractions, aggressive editor recruitment, and an editorial model that some peer-review specialists consider structurally problematic. Both are true. The right question is never "is Frontiers predatory?" but "is this specific Frontiers journal, for this specific paper, at this specific moment, the right choice?"

What Frontiers Actually Is

Frontiers Media is a Swiss-based open-access publisher founded in 2007 by a group of neuroscientists at EPFL. It now publishes more than 230 journals, primarily in the life sciences, medicine, psychology, and sustainability. Its flagship titles — Frontiers in Psychology, Frontiers in Neuroscience, Frontiers in Immunology, Frontiers in Plant Science — are widely indexed and widely cited.

Structurally, Frontiers pioneered the "collaborative peer review" model. Authors and reviewers interact directly through a platform, and reviewers who recommend rejection are typically replaced with reviewers more sympathetic to the paper. This is the part that generates most of the criticism — the model is designed to maximise acceptance, and critics argue it weakens gatekeeping.

The Fair Case on Both Sides

Why Reputation Varies So Much

A big part of what drives disagreement about Frontiers is field variance. In plant science and immunology, Frontiers journals are mainstream — cited, respected, routinely targeted. In psychology and psychiatry, the picture is more mixed. Some departments actively discourage submissions there; others have no such concern. A paper that sails through reviewer selection in one field would raise eyebrows in another.

The other driver is the age and scale of specific journals. Long-standing Frontiers flagship journals have built reputations through years of published work. Newer titles launched rapidly to fill niche gaps are harder to assess — they may become respected, or they may quietly disappear. This same pattern applies to large OA publishers generally, as we discuss in our MDPI journals assessment.

The Retraction Question

Frontiers has featured in a number of high-profile retractions, including editorial controversies where entire editorial boards resigned over publisher interference. These incidents are real and documented. They do not make every paper published in Frontiers suspect — but they do inform how some researchers, and some institutions, view publications there.

If you are considering a Frontiers journal, read three or four recent retractions in that specific journal (if any exist). The nature of the retractions matters more than the count. Retractions for data fraud are different from retractions for editorial procedural issues.

When Frontiers Makes Sense

Frontiers is often a reasonable choice when three conditions hold together. First, the specific journal is currently Scopus and/or Web of Science indexed — verify this on Scopus Source List before submission, not months before. Second, your field treats the specific journal as mainstream; ask a senior colleague in the same sub-discipline, not a generalist. Third, your paper is clean, empirical, and benefits from fast turnaround — Frontiers rewards tight data stories, not theory-heavy conceptual work.

If all three hold, a Frontiers publication can be genuinely useful — indexed, open-access, fast, and respectable. It is not a shortcut, but it is also not a red flag.

When to Choose Differently

Consider a different publisher if your paper is theoretical or heavy on methodological novelty, if your field views Frontiers with scepticism (ask colleagues), if your institution has an informal or formal list discounting Frontiers publications for promotion, or if the specific journal was delisted from Scopus in the last 24 months. In any of these cases, the downside risk outweighs the speed advantage.

The Bottom Line

Frontiers journals are legitimate in the sense that they are real, indexed, peer-reviewed, COPE-compliant academic journals. They are questionable in the sense that their peer-review model is lighter than traditional publishing, and their reputation varies sharply by field. Neither "yes they are predatory" nor "no they are a great choice" is accurate — the truth sits in a specific answer for a specific paper.

If you are deciding right now, work through three checks: verify the specific journal's current indexing, ask two senior colleagues in your sub-field about local reputation, and confirm your institution has no internal guidance against the publisher. If all three clear, submit with confidence. If any fails, choose differently. For the broader framework on spotting journal risks, read our pillar guide on how to identify predatory journals.
