Subclaims¶

q3 i? Novices required to study four hours daily scored statistically indistinguishably from unguided LLM novices studying three hours. → Bharat Anand 2026

Evidence¶

Bharat Anand 2026¶

Bharat Anand, Lihi Idan. (2026). Generative AI and the Productivity Divide: Human–AI Complementarities in Education and Knowledge Work (Working Paper). https://arxiv.org/abs/2605.18143 doi:10.48550/arxiv.2605.18143

q3 · i? · causal · r2

Time-on-task sub-condition within the LLM arm: OLS models comparing the two novice groups with controls for demographics, pre-intervention score, and Interaction Competence found no significant treatment coefficient for the additional time condition.

"Novices in the "more time" group scoredM=.37,SD=.22, statistically indistinguishable from unguided LLM novices,M= .38,SD=.23."

Discussion¶

Learner Variables¶

• Time and Continuity — predictor: learners who differ on it differ in outcomes

Related Claims¶

• Thoughtfully designed expanded learning time and opportunities are associated with positive academic and nonacademic outcomes, with the best-designed studies showing the strongest effects — the general claim this finding bears on, with the studies behind it
• In one randomized working-paper experiment, conceptual-map scaffolding gave LLM-using novices marginally higher scores (p < .10) and lower score variance, with a marginal benefit concentrated among low-AIC novices — related
• AI Interaction Competence, not GPA or prior knowledge, is the decisive moderator of LLM-assisted learning gains — related
• A daily learning diary alone (Group D) did not produce statistically significant pre-post gains on any measured outcome in an online mathematics preparation course — related
