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? Overall essay quality rose sharply after ChatGPT's introduction, driven mainly by improvements in grammar, style, and clarity, with more modest gains on substantive dimensions. → Calvin Isley 2026
q2 i? Quality gains persist when controlling for applicant pool composition. → 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
Pre/post comparison of LLM-assessed essay quality across six cycles, standardized to 2020 SD units and disaggregated by residency. Gains came from "large improvements in mechanical aspects of writing" with more modest substantive improvement, and persisted with applicant-quality controls.
"Figure 3 shows a sharp improvement in the overall quality of essays (blue line) after the introduction of ChatGPT, particularly for international applicants and especially in the most recent cycles, when use of AI was greatest. These gains come from large improvements in mechanical aspects of writing (grammar, style, and clarity, indicated by the red line), with more modest improvement along substantive dimensions"
