Pith's one-line read The paper claims that women are more likely to be acknowledged than listed as co-authors, especially for investigation and analysis roles, and that citation status can override gender in who receives authorship credit.
desk verdict A solid, honest empirical extension of prior credit-gap work, but the role-specific claim rests on a weakly validated keyword taxonomy and statistics that ignore dependence. read the letter →
The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The central object is the Authorship Rate, the share of contributors in a given role who are listed as authors rather than only acknowledged. The paper computes this rate separately for men and women, at the paper level and within man-woman collaborator pairs, for the three contribution types that appear on both the authorship and acknowledgment sides: Investigation and Analysis, Materials and Resources, and Writing. Authorship roles come from the CRediT taxonomy, a standardized contributor-role system; acknowledgment roles are inferred from a keyword-based taxonomy built on an existing codebook of acknowledgment wording. The status analysis splits scholars into the top and bottom 10% by citation count, within gender, and classifies collaborator pairs as high/high, high/low, low/high, or low/low.
What would settle it
Take a random sample of the acknowledgment sentences labeled by the keyword taxonomy, have annotators assign contribution roles by hand, and recompute the gender-specific authorship rates; if the gender gap in investigation and analysis disappears or reverses, the reported disparity is an artifact of the keyword mapping rather than a real difference in credit.
Extended reading notes
Core claim
The paper's central claim is that being listed as an author rather than only acknowledged is gendered. For contributions classified as Investigation and Analysis, women's authorship rate is lower than men's at the paper level, about 65% versus 70%, and at the collaboration level, about 86% versus 88%; a smaller but significant gap appears for Writing, while Materials and Resources shows no significant difference. The paper further claims that citation-based status interacts with these disparities: when a highly cited scholar collaborates with a less-cited scholar, the highly cited scholar is more likely to be listed as author irrespective of gender, and in the specific case of a highly cited woman paired with a less-cited man, the woman's authorship rate exceeds the man's. The authors read this as evidence that credit allocation tracks perceived success and power more than gender alone, while still leaving women disadvantaged overall because women are underrepresented among highly cited scholars.
Load-bearing premise
The whole comparison depends on the assumption that the words used in acknowledgment sentences, such as 'help,' 'data,' and 'discussion,' identify the same contribution roles that CRediT assigns to authors, so that a gender difference in role classification reflects a difference in credit rather than a difference in wording.
Editorial extensions
If this is right
- Women's contributions to investigation and analysis are systematically under-credited as authorship relative to men's, so auditing role-specific credit could reduce the gap.
- Because citation status strongly predicts authorship, raising women's visibility and citation counts could improve their credit share even without changing authorship norms.
- The finding that highly cited women paired with less-cited men receive authorship more often suggests that status can override gender bias, making status hierarchies a relevant intervention point.
- The absence of a gender gap in Materials and Resources indicates the inequity is tied to particular intellectual roles rather than to all contributions.
- The U-shaped relationship between number of authors and number of acknowledgees implies that large-team research follows different credit-allocation norms that merit separate study.
Reading between the lines
- The authors leave implicit that the gender authorship gap may be partly a downstream effect of citation inequality; if so, one testable prediction is that the gap narrows or disappears when men and women with equal citation counts collaborate in matched pairs.
- Because the dataset excludes individuals who are acknowledged but never appear as authors, the true gender gap in credit may be larger than measured, since women are overrepresented among acknowledgees.
- A direct extension would compare the keyword-based authorship rates with rates obtained by human annotation of the same acknowledgment sentences; if the two diverge by gender, the taxonomy itself needs correction.

Referee Report
Summary. The paper analyzes 19,885 PLOS articles published 2016-2021, linking CRediT authorship roles with a keyword-based taxonomy of acknowledgment roles, and computes an Authorship Rate (AR) by gender and contribution role at both the paper level and the collaboration level. The central claim is that women are more likely to be acknowledged than listed as co-authors, especially in the Investigation and Analysis (I&A) role, where the paper-level AR is roughly 70% for men versus 65% for women. The paper also examines collaboration pairs by citation-based status, finding that highly cited scholars receive authorship more often regardless of gender, and that highly cited women paired with less-cited men are more likely to be authors than the men. The authors discuss limitations including the PLOS-only sample, the keyword-based acknowledgment taxonomy, and the use of gender-specific citation cutoffs.
Significance. If the central result is valid, the paper provides a large-scale, role-resolved quantitative description of gendered credit allocation, going beyond authorship-only analyses by systematically linking authors and acknowledgees. Its strengths include a large sample (122,072 authors and 63,343 acknowledgees), a rigorous linkage to scholar IDs via MAG, explicit research questions, and a transparent acknowledgment of several limitations. The finding that status dynamics may modulate gendered credit patterns is a potentially valuable contribution to the credit-allocation literature. However, the central claim depends on an acknowledgment-role taxonomy that is validated only by small, partially described manual checks, and the statistical tests ignore the non-independence of observations; these issues must be addressed before the conclusions can be regarded as established.
major comments (3)
- [§2.2.2, Table 2, Appendix A] The acknowledgment-role classification is load-bearing for the central claim, but the keyword taxonomy in Table 2 is not validated by gender. The words 'help' and 'assistance' are assigned to Investigation and Analysis (I&A) with no ambiguity check, while Appendix A reports manual checks only for a handful of multi-meaning words, without counts, sampling fractions, or inter-rater agreement. Because I&A accounts for 73%-80% of women's acknowledgment roles (Fig. 2c), a differential tendency for women to be thanked for generic 'help' or 'assistance' rather than for specific technical tasks such as 'analysis' or 'code' could produce the observed lower female Authorship Rate in I&A without any true difference in contribution level. The authors should validate the mapping on a gender-stratified random sample of acknowledgment sentences with reported agreement statistics, or rerun the analysis using an unambiguous subset of keywords.
- [§2.3, §3.2, Fig. 3] The t-tests used to compare Authorship Rates ignore the hierarchical structure of the data. At the paper level, each contributor is treated as an independent observation even though the same scholar appears in multiple papers, and at the collaboration level, the same scholar contributes to many pairs, so the 259,652 paired observations in the I&A comparison are not independent. The reported p-values therefore overstate precision, and with large N even substantively trivial differences (e.g., 88% vs 86% in collaboration-level I&A) become highly significant. I recommend hierarchical models or cluster-robust standard errors with clustering at the scholar or paper level, and reporting of effect sizes alongside p-values.
- [§2.4, §3.3, Fig. 4] The status analysis defines 'highly cited' and 'less cited' using gender-specific 10th and 90th percentiles of the citation distribution, so a 'high-woman' may have fewer citations than a 'high-man', and the absolute citation gap between a 'less-man' and a 'high-woman' is not controlled. The conclusion in §3.3 that 'power dynamics based on academic status or perceived success can override, or even reverse, gender-based disparities' is therefore weakened: the reversal in the less-man/high-woman pair could be an artifact of the relative-within-gender status labels rather than of an actual status effect. The paper acknowledges the definitional issue in §2.4, but the interpretation in §3.3 does not flag it as a caveat; the authors should either use gender-common citation cutoffs or, if they keep gender-specific cutoffs, explicitly recast the result as a relative-status comparison and test robustness to alternative cutoffs.
minor comments (7)
- [Abstract] The abstract states 'over 20,000 authors and 60,000 acknowledged individuals', but §3.1 reports 122,072 authors and 63,343 acknowledged individuals; please reconcile the numbers.
- [§2.1] There is a typo: 'refered' should be 'referred'; also, the capitalization of 'CRediT' is inconsistent ('CrediT' appears in the same section).
- [§3.1] The sentence 'the number of remains relatively stable' appears to be missing a word; please revise for clarity.
- [Table 2] The keyword 'data' appears under both I&A and M&R; the disambiguation rule described in Appendix A (labeling 'data' as M&R only when accompanied by 'providing', 'provide', 'provided', or 'database') should be stated in a table note for clarity.
- [Figure 2(c)] The acknowledgment proportions for I&A differ noticeably between men (73.1%) and women (80.4%); the authors do not comment on this gap, which is directly relevant to the main analysis.
- [§2.4] The sentence 'The sample included as follows' is grammatically incomplete; please specify the sample being described.
- [Data and code availability] The paper does not state whether the analysis code or processed data are available; given that the underlying acknowledgment dataset is public (Kusumegi and Sano 2022), a data/code availability statement would strengthen reproducibility.
Circularity Check
No circular derivation: the empirical authorship-rate analysis is self-contained; the only self-citations are data/codebook sources, and the acknowledged measurement-validity limitation is not circularity.
full rationale
The paper's central claims are computed directly from observed counts of authors and acknowledgees, using the Authorship Rate defined in Sec. 2.3 as a ratio of observed author counts to observed contributor counts. There is no fitted parameter that is later renamed as a prediction, no quantity is defined in terms of the conclusion, and no equation reduces to its own input. The acknowledgments-role taxonomy in Table 2 is based on an external codebook (Paul-Hus and Desrochers 2019) plus manual checks, and the authors explicitly flag in the Discussion that keyword-based classification makes role alignment challenging; that is a measurement-validity limitation, not a circular step. The use of the authors' own prior dataset (Kusumegi and Sano 2022) is an ordinary use of a published data source, not a load-bearing self-citation of an unverified theorem, and the status classification using top/bottom 10% citation cutoffs computed separately by gender is a stated design choice, not a definition that forces the headline result. The empirical finding that women are more frequently acknowledged than credited in Investigation and Analysis therefore does not follow by construction; it is an observed statistical pattern whose reliability depends on data quality and construct validity rather than on circular reasoning.

The issue of gender bias in scientific publications has been a topic of ongoing debate. One aspect of this debate concerns whether women receive equal credit for their contributions compared to men. Conventional wisdom suggests that women are more likely to be acknowledged than listed as co-authors. In this study, we analyze data from over 20,000 authors and 60,000 acknowledged individuals across nine disciplines in open-access journals. Our results confirm persistent gender disparities: women are more frequently acknowledged than credited as co-authors, especially in roles involving investigation and analysis. To account for status and disciplinary effects, we examined collaboration pair composed of highly cited and less-cited scholars. In collaborations, highly cited scholars are more likely to be listed as an author regardless of gender. Notably, highly cited women in such pairs are even more likely to be co-authors than their men counterparts. Our findings suggest that power dynamics and perceived success heavily influence the distribution of credit in scientific publishing. These results underscore the role of status dynamics in shaping authorship and call for a more nuanced understanding of how gender, power, and recognition interact in scientific publishing. Our findings offer valuable insights for scholars, editors, and funding committed to advancing equity in science.

Is this inequality rooted in gender itself, or by differences in citation counts?
Discussion Our findings primarily highlight two key points: 1) Men are generally more likely to receive authorship credit, specifically in the roles of Investigation & Analysis (I&A) and Writing, with the disparity being particularly pronounced in I&A. 2) Regardless of gender, when scholars with different levels of status collaborate, those with higher ci...
