How to spot and avoid predatory journals

Predatory journals collect publication fees without providing what a journal exists to provide: honest peer review, editorial standards and durable indexing. They target exactly the researchers with the most at stake and the least time, which is why Indian medical faculty approaching a promotion deadline are among their favourite victims.

This guide gives you the warning signs, explains what a predatory paper can cost you, and covers the harder question of what to do if you have already submitted.

Why independent verification matters

A deceptive journal can take a fee without providing credible peer review, preservation or discoverability. Its indexing badge may be false, copied from another title or based on coverage that has ended. Because duplicate publication is generally unethical, publishing in an unsafe venue can also make it difficult to submit the same work to a legitimate journal later.

The warning signs

How they approach you

• Flattering email invitations to submit "your esteemed research", often citing an unrelated paper of yours.
• Promises of review and publication in days. Real peer review takes weeks to months.
• Fee negotiations by email or WhatsApp, or fees demanded before review.

What their websites look like

• Indexing claims that fail verification in the database's own list. This is the decisive test; our guide on verifying journal indexing takes fifteen minutes.
• Fake metrics: "SJIF", "Global Impact Factor", Index Copernicus values presented as an Impact Factor.
• Absurdly broad scope: "International Journal of Medicine, Engineering and Management".
• Editorial boards with unverifiable names, or real academics listed without their knowledge.
• No retraction policy, no COPE membership, no physical address that survives a map search.

The structural tell

A legitimate journal's incentive is to reject weak papers; its reputation is its business. A predatory journal's incentive is to accept everything; your fee is its business. Every warning sign above follows from that difference.

Before you submit: the three-check habit

• Verify indexing in the database source list, by ISSN, for the current year
• Use Think-Check-Submit (thinkchecksubmit.org), the checklist maintained by the international publishing community
• Ask a colleague who has published there what the review process was actually like; real journals produce real reviewer reports

If you have already submitted or published

1. Submitted but not published: withdraw formally, in writing, immediately, and keep the correspondence. Do not pay any "withdrawal fee"; that demand itself confirms the diagnosis.
2. Published and the journal was predatory from the start: get advice before acting. Options are limited, but do not list the paper for promotion credit, and do not attempt to republish the same data elsewhere without disclosure; duplicate publication is a separate integrity problem.
3. Published, and the journal was later delisted: this is more defensible; what matters is the journal's indexing status in the year your paper appeared. Preserve dated evidence of the indexing at publication time.

Our position

MedPub Assist never submits to or recommends predatory journals under any circumstances, including deadline pressure. Every journal we shortlist comes with documented, current indexing evidence, because the entire value of a publication, for your career and for science, depends on the journal being real.
