There are a few limited circumstances where an academic citing their own work is quite reasonable. For example, when we want to reference an argument or description provided in our earlier work. Indeed, recycling text from earlier work without citation is a kind of self-plagiarism that can be problematic. We might also reference earlier discussion in earlier research outputs that is pertinent to our recent work. In other circumstances, there is not unreasonable worry that self-citation is an attempt to game the research metric and performance systems. Institutions should urge its researchers and monitor if such gaming is occurring.
This study provides evidence of career and gender effects in selfcitations, and of a higher similarity of citing and cited papers in the case of self-citations than
of citing. Citations are also central to research evaluation, thus creating
incentives for researchers to cite their own work. Using a dataset containing
more than 63 million articles and 51 million disambiguated authors, th…
