q2 i? Re-estimating the grade specification under five susceptibility measures, post-AI coefficients are null under clean pre-COVID anchors but positive and significant under COVID-window anchors. → Dumlao 2026

q2 · i? · causal · r2

Treatment-measure robustness analysis re-estimating the preferred grade specification under five candidate susceptibility anchors. The authors state this is "direct evidence that a positive reading of the average effect reflects the COVID shock rather than ChatGPT", motivating the 2019 anchor.

"the post-AI coefficient is null under the clean pre-COVID anchors (0.030, n.s., for the 2019 measure used here; 0.039, n.s., for the 2015 to 2019 pre-COVID average) but positive and significant under the COVID-laden anchors (0.115,p <0.05, for the 2022 measure; 0.160,p <0.01, for the 2020 to 2022 COVID-window measure)."

Discussion¶

Related Claims¶

• The share of students earning at least an A rises in more susceptible courses after ChatGPT under the preferred bound, but the shift fails parallel trends and is read as descriptive, not causal — related
• More GenAI-susceptible courses show no raised grade floor after ChatGPT: passing-margin and failing/withdrawal probabilities are null under both COVID assumptions — related
• Effects of GenAI availability on self-reported understanding are insignificant; effects on interest are significant only under the transient-COVID assumption — related
• GenAI availability produced no significant differential effect on final grades in more GenAI-susceptible courses relative to less susceptible ones — related
• Grade effects of GenAI availability do not differ across terciles of students' prior academic preparation, robust across multiple ability proxies — related
