Predatory journals publish quickly, for a fee, without real scientific vetting. They look legitimate on the surface — professional websites, claims of being "international" and "peer-reviewed." But when you submit, you get neither a serious review nor lasting academic value — only an invoice. Here is how to tell them apart.
Why are predatory journals dangerous?
A paper published in a predatory journal is often disqualified in promotion and incentive criteria, attracts no citations, and can damage your reputation. Worse, your paper may become impossible to resubmit to a serious journal because it is technically "published." The risk is far greater than the money lost.
The strongest red flags
1. Promises of instant acceptance
A genuine peer review process usually takes weeks to months. "Acceptance in 48 hours" or "published within a week" is the clearest sign that no serious vetting happens.
2. Unsolicited, exaggerated emails
Mass emails starting with "Esteemed Professor, for your remarkable work..." and inviting submissions unrelated to your field are typical predatory marketing. Legitimate journals rarely send individual invitations in this tone.
3. Unverifiable indexing claims
Predatory journals claim to be "Scopus indexed" or have a "high Impact Factor" but it can't be verified. Check: is the journal really in the Scopus source list, the Web of Science Master Journal List, or DOAJ? Verify the claim at the source, not on the journal's own page.
4. Hidden, vague or inflated APCs
Legitimate open-access journals state the APC clearly before submission. A fee that arrives as a surprise with the acceptance letter, or that is negotiable, is a serious warning.
5. An opaque editorial board
If board members aren't named, their affiliations can't be verified, or members are unaware they are "on the board," the journal is not trustworthy.
Three-minute verification checklist
- Is the journal listed in DOAJ?
- Is it in the Scopus source list or the Web of Science Master Journal List?
- Are the editorial board members real and verifiable?
- Is the APC clearly stated before submission?
- Is the review time realistic (weeks/months, not days)?
A single flag isn't a verdict; but when two or more appear together, staying away is the safest move.
The safe path
Verifying a journal's legitimacy before submission is an inseparable part of choosing the right journal. For researchers in Türkiye, an extra safety layer is to target journals within the TR Dizin index, which pass a defined review. When in doubt, not submitting is always better than submitting to the wrong place.
