Note that journal quality and predatory publishing are related but different things. While all predatory journals are low quality, not all low-quality journals are necessarily predatory. Some characteristics of low-quality and predatory journals may be caused by inexperienced editorial staff, or due to cultural differences for non-US-based publications.
Quality also occurs on a spectrum, from clearly predatory and worthless journals, to new journals that have not yet had time to develop a reputation and best practices, and well-known high-quality journals.
In addition, it is important to keep in mind that journal quality is not an indicator of research quality. Good research may be inadvertently published in predatory journals, and bad research might slip by peer review and be published in well-known journals. That is why it is important to read research skeptically and practice critical appraisal.
Think. Check. Submit is a cross-organization effort to help researchers figure out whether a specific journal is a viable option for publishing research. Use it to evaluate journals that are new to you before submitting to them.
