Real-Time Group Dynamics with LLM Facilitation: Evidence from a Charity Allocation Task

Aaron Parisi, Alden Hallak, Crystal Qian, Nithum Thain, Vivian Tsai

Claims

C1strongest claim

Across both studies, LLM facilitation did not significantly improve group consensus in either study, yet participants consistently preferred facilitated discussion. We additionally identify two governance-relevant risks. First, algorithmic steering: facilitators shifted select charity-level allocations by up to 5.5 percentage points -- directly affecting the final charitable payout -- even when aggregate agreement metrics remained unchanged. Second, an illusion of inclusion: participants cited inclusivity as their primary reason for preferring LLM facilitators, yet neither survey nor transcript-based measures of participation equity improved.

C2weakest assumption

That the specific charity allocation task with real financial stakes and text-only chat generalizes to other group deliberation settings, and that the chosen survey and transcript metrics adequately capture steering and equity effects without missing subtle dynamics.

C3one line summary

LLM facilitators in real-stakes group charity decisions shift specific allocations without raising consensus or participation equity, yet increase perceived trust and preference for the process.
