Subclaims¶

q2 i? At turn and conversation levels, a skill-matched Executive LLM elicited significantly more evidence for that skill than Independent Agents (Fisher exact test, p≤0.05), with conversation-level evidence rates of 92.4% for PM and 85% for CR. → Globerson 2026 q2 i? Steering toward one sub-skill reduces evidence of the other (crossover), except for PM at the conversation level where both Executive LLM versions yielded similar rates. → Globerson 2026 (2)

Evidence¶

Globerson 2026¶

Globerson, A., Keeling, A., Choudhury, A., et al. (2026). Towards Scalable Measurement of Durable Skills. https://arxiv.org/abs/2609.15864 doi:10.48550/arxiv.2609.15864

q2 · i? · causal · r2

Randomized comparison of three protocols (CR Executive LLM, PM Executive LLM, Independent Agents) in 373 human conversations; starred brackets denote statistically significant differences (p≤0.05) using the Fisher exact test in Figures 6 and 7. "an Executive LLM focused on a skill always elicits significantly more evidence"; the skill-matched conversation-level rate was 92.4% for PM and 85% for CR.

"First, it can be seen that an Executive LLM focused on a skill always elicits significantly more evidence for that skill than the Independent Agents."

q2 · i? · causal · r2

Same randomized human-conversation comparison: a crossover effect in which each Executive LLM version raises its matched skill's evidence and lowers the mismatched skill's, significant in three of four comparisons; PM at conversation level showed no significant difference between versions.

"That is, steering the conversation towards CR increases evidence of CR but reduces evidence of PM and vice versa. This results in a significant difference in three of the four figures, except for measuring PM at the conversation level (Figure 7, Right), where similar information levels are obtained for both Executive LLM versions."
