Women are criminally underrepresented in science and technology. In fact, across a range of STEM fields, they are actively discriminated against. As a new study uploaded to the pre-print server arXiv also reveals, male scientists are helping themselves get ahead far more than women are when it comes to boosting the profile of their own work.
When academics compose research papers, they reference previous studies in order to back up their arguments. Normally, these studies are written by other researchers, but the authors of the paper can cite their own work if they so desire.
This practice of self-citation is widespread, and there’s nothing inherently wrong with it. After all, if you write a paper that later forms the basis of much of your research, then it’s only right that you reference it. However, as this study by researchers at Stanford University, New York University, and the University of Washington reveals, men do this far more often than women.
As part of an investigation into self-citation, the team analyzed 1.5 million papers in the academic database JSTOR. Of these papers’ 8.2 million citations, 775,000 references (9.5 percent of them) were self-citations. Although this seems high, the real shock came when they broke down the numbers along gender divides.
Between 1779 and 2011, men reference themselves 56 percent more than women. In the last 20 years, men self-cite a staggering 70 percent more than women. Their research clearly shows a trend of male self-citation increasing over time across any academic field, from philosophy to biology. Women, conversely, are 10 percent more likely to never cite their own previous work at all compared to men.
“If men are more likely to cite their own work, their papers will appear to be higher quality partly because of men’s own efforts at self-promoting them,” the authors write in their study.
