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.
q3 i3 Letters rewritten by the AI tool were rated higher for writing quality (d=1.66) and considerably more likely to secure a hypothetical job interview (d=0.75) than letters rewritten by professional editors. → Benjamin Lira 2025

Benjamin Lira 2025¶
Benjamin Lira, Todd Rogers, Daniel G. Goldstein, Lyle Ungar, and Angela L. Duckworth. (2025). Coach not crutch: Evidence that AI can improve writing skill despite reducing effort. https://arxiv.org/abs/2502.02880 doi:10.48550/arxiv.2502.02880
q3 · i3 · causal · r3
Within Study 3, the AI tool was used to rewrite each letter assigned to the editor pool, creating a counterfactual comparison. Letters were "rated higher for writing quality" (d=1.66) and "more likely to secure a hypothetical job interview" (d=0.75) relative to editor rewrites.
"letters rewritten with the AI tool were rated higher for writing quality (d= 1.66,p< .001), and when shown to independent raters, they were considerably more likely to secure a hypothetical job interview (d= 0.75,p< .001)"
