Subclaims¶

q2 i1 A higher number of 'Undecidable' labels in initial coding predicts greater accuracy improvement through discussions (effect size 0.123, p<0.01). → Jeongyeon Kim and John Mitchell 2026 q2 i1 A lower number of 'Undecidable' labels after discussion-prompted coding predicts greater accuracy improvement (effect size -0.369, p<0.0001). → Jeongyeon Kim and John Mitchell 2026 (2)

Evidence¶

Jeongyeon Kim and John Mitchell 2026¶

Jeongyeon Kim and John Mitchell. (2026). How AI Coders Discuss, Disagree, and Reach Consensus: Challenges and Opportunities for LLM-Based Qualitative Coding. arXiv. https://arxiv.org/abs/2609.11109 doi:10.48550/arxiv.2609.11109

q2 · i1 · design · r2

Mixed-effects analysis of labeling uncertainty across the four datasets. The pre-discussion row reports "(3.274, 0.123)", p<0.01 with effect size 0.123; the article interprets that dialogue "naturally clarifies uncertainties and builds a precise, shared understanding."

"Number of Undecidable Labels in Initial Coding < 0.01 ** (3.274, 0.123) The higher the number of ‘Undecidable’ labels before discussion, the greater the accuracy improvement through AI agent discussions."

Jeongyeon Kim and John Mitchell 2026 (2)¶

q2 · i1 · design · r2

Same mixed-effects analysis. The post-discussion row reports "(-14.476, -0.369)", p<0.0001 with effect size -0.369; persistent undecidable labels indicate a small accuracy improvement from discussions.

"Number of Undecidable Labels in Discussion-Prompted Coding < 0.0001 **** (-14.476, -0.369) The lower the number of ‘Undecidable’ labels after discussion, the greater the accuracy improvement through AI agent discussions."
