Claiming Novelty, Claiming Authority: Gender Gaps in Scientific Impact across Disciplines

How does gender shape who can successfully claim authority in science, and how does this vary across disciplines? Drawing upon theories of doing gender and feminist epistemologies, I examine a key mechanism through which scientific authority is established: novelty claims, defined as rhetorical statements that frame research as novel, distinct from actual novelty. These claims operate as gendered professional practices linking gender to scientific impact. Through analysis of 106,125 papers from SciSciNet and Microsoft Academic Graph databases, I find that novelty claims mediate gender gaps in citations differently across disciplines. In STEM fields, women first and last authors make fewer novelty claims than men, and this is associated with fewer citations. In humanities and social sciences, novelty claims remain positively associated with citations, but there are no gender differences in their use or in citations. These patterns persist after controlling for women’s representation in each field, indicating that gender hierarchy gets reproduced through deeper epistemic power relations rather than demographic imbalance.
