Gender differences in how scientists present the importance of their research

Do men and women describe their own research differently? And if so, does it cost them? A team from Mannheim, Yale, and Harvard Medical School used Genderize.io to find out — and the answer to both questions was yes.

The data

Marc Lerchenmueller, Olav Sorenson, and Anupam Jena analyzed 101,720 clinical research articles and 6.2 million general life science articles indexed in PubMed between 2002 and 2017. They used Genderize.io to assign gender to first and last authors, applying a 90% probability threshold that yielded an average assignment confidence of 99.5%.

They then searched every title and abstract for 25 positive-framing words — terms like "novel," "unique," "unprecedented," and "promising" — that signal a paper's importance to readers, journalists, and citation algorithms.

The gap

Articles with both a female first author and a female last author used positive framing in 10.9% of titles or abstracts. For articles with male first and last authors, the figure was 12.2%. That is a 12.3% relative difference — not enormous, but consistent across fields and years.

The gap widened in high-impact journals. In journals with an impact factor above 10, women were 21.4% less likely to frame their research in positive terms.

The citation cost

Positive framing was not just cosmetic. Papers that used words like "novel" or "unprecedented" received 9.4% more citations overall. In high-impact clinical journals, the boost was 13%. Women's comparative reluctance to use these terms was associated with a measurable citation penalty — not because their science was weaker, but because they described it more conservatively.

What it means

The study adds a subtle dimension to the gender gap in academic publishing. It is not enough to get published; how you frame the work determines how widely it is read and cited. If women systematically undersell their findings — whether due to socialization, risk aversion, or a realistic assessment of how self-promotion is received differently for women — the effect compounds across a career. Fewer citations lead to fewer grants, fewer invitations, and slower promotion.

The finding also raises an uncomfortable question for the scientific community: if citation counts partly reflect marketing rather than merit, what does that say about how science allocates prestige?
