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 i? Completion time falls by 0.961 minutes for low-education and 1.514 minutes for high-education participants; the difference in treatment effects is not statistically significant. → Guillermo Cruces 2026

q3 · i? · causal · r3
Results-section analysis of preregistered task completion time (minutes, top-coded at 20) in the randomized experiment. The article reports time "falls by 0.961 minutes" for low-education and "1.514 minutes" for high-education participants.
"Among low-education subjects, time falls by 0.961 minutes relative to a control-group average of 10.697 minutes (significant at the 10% level). Among high-education participants, the reduction is larger at 1.514 minutes relative to a control-group average of 10.423 minutes (significant at the 1% level)."
Discussion¶
Related Claims¶
- The equalizing effect of AI assistance operates through both content and writing subcomponents, with incomplete convergence in each — related
- AI assistance raises the probability of correctly identifying the task's root cause for both education groups, with near-equalization among treated participants — related
- AI assistance reduces subjective mental effort across all tasks even when it does not reduce completion time, dissociating time and effort — reports the opposite
- No AI participants spent roughly 1.5 times as long on the assessment as AI-Assisted participants, descriptively reported as a marker of offloading — related
- AI assistance closes about three-quarters of the baseline education-based task-performance gap, though a 0.139 SD gap remains among treated participants — related
- Access to a generative-AI assistant raises task performance for both lower- and higher-education adults, with significantly larger gains for lower-education participants — related
