Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? After adjusting for machine-generated quality measures, actual AI authorship, and applicant characteristics, staff ratings remain negatively correlated with perceived AI use (coefficient -0.131, p < 0.05 in the unadjusted-with-fixed-effects model). → Calvin Isley 2026
Evidence¶
Calvin Isley 2026¶
Calvin Isley, Johann D. Gaebler, and Sharad Goel. (2026). AI-written admissions essays are widespread but penalized. arXiv preprint. https://arxiv.org/abs/2609.22549 doi:10.48550/arxiv.2609.22549
q2 · i? · associational · r2
Regression analysis of staff quality ratings (Table 2) adjusting for machine-generated essay quality, actual AI-written status, and applicant demographics, with reviewer fixed effects. Staff ratings remained "negatively correlated with perceived AI use"; essays deemed very likely AI received markedly lower scores (Fig. 5).
"After this adjustment, we still find that staff ratings are negatively correlated with perceived AI use, providing further evidence that AI use itself was penalized by admissions staff."
Discussion¶
Related Claims¶
- Admissions officers can often discriminate AI-written from human-written essays, achieving an AUC of 0.70, well above chance but below commercial detectors — related
- Applicants who submitted AI-written essays were admitted at lower rates than comparable non-users, with an estimated penalty of about 1.5 percentage points per AI-written essay — related
- By the 2025 admissions cycle, a majority of applicants to the studied public policy master's program submitted at least one primarily AI-generated essay despite an explicit prohibition — related
- The availability of AI assistants improved the quality of submitted admissions essays, particularly mechanical aspects and especially for international applicants — related
