We argue that editorial independence, through robust practice of publication ethics and research integrity, promotes good science and prevents bad science. We elucidate the concept of research integrity, and then discuss the dimensions of editorial independence. Best practice guidelines exist, but compliance with these guidelines varies. Therefore, we make recommendations for protecting and strengthening editorial independence.

We question whether blacklists are the best answer to the serious problem of predatory journals. In conjunction with the worrying recent rise in the number of predatory journals, a remarkable number of blacklists have been compiled for specific scientific fields. However, predatory journals are continuously changing names and publishers; they are set up to make easy money and buried shortly after. Predatory journals have such a rapidly evolving nature that it is hard to keep track of them and keep blacklists up to date. We therefore propose a focus on ‘whitelists’ and directories of virtuous journals rather than on blacklists of pseudo-journals. We suggest that a set of criteria be determined that journals have to meet to be qualify as legitimate. In addition, the scientific community should come up with strategies to close the established biomedical databases to predatory journals, thus preventing them from achieving global exposure.
