Causal Analysis of Author Demographics in Academic Peer Review

arXiv:2603.06641v1 Announce Type: new
Abstract: Academic meritocracy is jeopardized by systematic imbalances; for example, whereas Black and Hispanic individuals constitute over 30% of the U.S. population, they represent fewer than 10% of tenured academics in science and engineering. Peer review serves as a crucial gatekeeper in this process, however it encounters ongoing issues over biases that may hinder scientific advancement. The issue is now exacerbated by the growing influence of artificial intelligence (AI) in academic assessment. This paper transcends correlation to quantitatively assess the independent impacts of author demographics, including race, gender, and country of affiliation, on paper acceptance rankings. We utilize a causal inference methodology on a dataset of 530 papers, simulating the academic selection process by employing the prestige of the publication venue as a surrogate for review rank. Our research indicates statistically substantial causal disadvantages for authors from minority racial groups (average treatment effects [ATE]: -0.42 points in ranking), female authors (ATE: -0.25), and those associated with institutions in the Global South (ATE: -0.57). The exhibited biases emphasize the pressing necessity for fairness interventions in both conventional and AI-based review processes, indicating that such measures are essential for establishing a more equitable and credible scientific environment.
