Does Splitting a Triage Decision Across Agents Hide Bias or Help Catch It? A Multi-Agent Simulation Study of LLM-Based Resource Allocation Under Audit Capacity Constraints
TL;DR
A multi-agent simulation study reveals that distributing triage decisions across multiple agents does not significantly reduce bias in resource allocation. However, audit capacity plays a crucial role in detecting biased outcomes.
✦ Why It Matters
Ensure adequate audit capacity in multi-agent systems to effectively detect and address bias in decision-making.
Key Takeaways
- Distributing decisions across agents does not reduce bias significantly.
- Audit capacity is critical for detecting biased outcomes.
- Overloaded auditors miss a significant percentage of biased cases.
- Implement robust auditing processes to improve bias detection.
How It Works
The study uses a synthetic disaster-triage simulator to create paired cases that are clinically identical except for one demographic attribute. By comparing outcomes from a single-agent model to a nine-agent pipeline, the researchers assess how decision distribution affects bias.
