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.
q2 i? The probability of earning at least an A rises by 0.107 (SE = 0.046, p < 0.05) under the preferred post-AI bound, but falls to a non-significant 0.030 under the conservative net-COVID bound and fails the parallel-trends test. → Dumlao 2026

q2 · i? · causal · r2
Grade-distribution DiD on the at-least-A threshold indicator. The authors state the shift "is not robustly identified in our data": the net-COVID estimate is 0.030 (SE = 0.018, n.s.), and the threshold fails parallel trends (p = 0.002 COVID-excluded).
"The probability of earning at least an A rises by 0.107 under the preferred post-AI bound (SE = 0.046,p <0.05), close to the 13 percentage point A-share increase Chirikov (2026a) reports."
Discussion¶
Related Claims¶
- More GenAI-susceptible courses show no raised grade floor after ChatGPT: passing-margin and failing/withdrawal probabilities are null under both COVID assumptions — related
- GenAI availability produced no significant differential effect on final grades in more GenAI-susceptible courses relative to less susceptible ones — related
- Positive average grade effects appear only under COVID-laden treatment anchors, indicating such readings reflect the COVID shock rather than ChatGPT — related
- Effects of GenAI availability on self-reported understanding are insignificant; effects on interest are significant only under the transient-COVID assumption — related
