The Dutch publisher Elsevier is investigating hundreds of researchers whom it suspects of deliberately manipulating the peer-review process to boost their own citation numbers.
The publisher is looking into the possibility that some peer reviewers are encouraging the authors of work under review to cite the reviewers’ own research in exchange for positive reviews — a
frowned-on practice broadly termed coercive citation.
Elsevier’s probe has also revealed that several of these reviewers seem to be engaging in other questionable publishing practices in studies that they have themselves authored. The Elsevier analysts who uncovered the activity told
Nature that they “discovered clear evidence of peer-review manipulation” and of academics publishing the same studies more than once. Elsevier said that their investigations will lead to some of these studies being retracted.
But it said it won’t be necessary to retract any studies found to be affected by coercive citation because the authors aren’t responsible for the problem, and citation manipulation doesn’t affect the research.
