Subclaims¶

q2 i? Fisher's exact tests found subject focus instructions did not improve conversation information levels vs no focus, in both Independent Agents and Executive LLM settings and for both skills (all p > 0.6). → Globerson 2026

q2 · i? · causal · r2

In the randomized Vantage experiment, roughly half of subjects received no focus instructions and half received instructions focusing on one of the two skills. Fisher's exact test found "subject focus had no significant effect" in either setting; the null does not establish equivalence.

"Results showed that subject focus had no significant effect, both in the Independent Agents and Executive LLM settings and for both skills (all at𝑝 > 0.6)."
