q2 i? Across minimum-turn thresholds, mean and median score contrasts between conversations with all three dimensions observed and those with at least one not observed remain small and vary in magnitude and sometimes direction, showing no stable performance difference. → Jorge Fábrega 2026

Evidence¶

Jorge Fábrega. (2026). Same Performance, Different Process: Epistemic Ownership in AI-Mediated Education. Preprint. https://arxiv.org/abs/2610.02731 doi:10.48550/arxiv.2610.02731

q2 · i? · associational · r1

Descriptive comparison of standardized assignment scores for 134 of 150 conversations with exact score linkage, across minimum-turn thresholds (Table 4). The article reports the contrasts "do not reveal a stable performance difference"; no significance test or effect size is printed, so this is a descriptive null, not an equivalence finding.

"Across the alternative opportunity thresholds, the score comparisons do not reveal a stable performance difference between conversations in which all three dimensions are observed and those in which at least one is not."

• Direction is observable in nearly all AI-mediated conversations, while Integration and Evaluation become progressively more observable as conversation length increases — related
• Identical assessed performance can coexist with different observable configurations of Direction, Integration, and Evaluation, even when score and conversation length are held constant — related
