Subclaims¶

q3 i? High-education control participants outperform low-education participants in both writing and content, and AI improves both dimensions for both groups. → Guillermo Cruces 2026 q3 i? Among treated participants, residual gaps of 0.122 SD in writing and 0.136 SD in content are underpowered (p-values 0.127 and 0.122). → Guillermo Cruces 2026

q3 · i? · causal · r2

Preregistered subcomponent analysis in the randomized experiment's results section. The article reports treated high-education participants "still outperform low-education individuals by 0.122 SD in writing and 0.136 SD in content", underpowered differences.

"Among treated participants, high-education individuals still outperform low-education individuals by 0.122 SD in writing and 0.136 SD in content, although we are underpowered to detect these differences (p-values are 0.127 and 0.122, respectively)."

Related Claims¶

• 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
• AI assistance reduces task completion time in both education groups, the only outcome without an equalizing pattern — 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
• How genAI is used, not who uses it, predicts whether independent performance declines or improves — related
• The bespoke GenAI workflow operated as a modest equalising mechanism, with students reporting inclusive participation regardless of prior AI or drawing experience — related
• Outcome convergence after collaboration is low, and higher for application-oriented than factual knowledge — related
