Beyond Arrow's Impossibility: Fairness as an Emergent Property of Multi-Agent Collaboration
This research explores how fairness in large language model systems emerges through multi-agent interaction and negotiation, challenging traditional views of fairness as a property of individual models. Using a hospital triage framework, we demonstrate that collaborative deliberation can achieve fairer resource allocations than single agents alone, even when facing inherent theoretical limits like Arrow's Impossibility Theorem.

Fairness as a System Property
Unlike single-model approaches where fairness is a static constraint, our research shows that in multi-agent systems, fairness emerges as a dynamic, procedural outcome of collaborative interaction. This shift in perspective is crucial for designing robust and adaptable ethical AI solutions.
Our research demonstrates that multi-agent collaboration can lead to allocation outcomes that are up to 25% fairer on key ethical metrics than allocations proposed by individual, unassisted agents. This improvement arises not from central optimization but through dynamic negotiation.
The Deliberative Arena: A Framework for Negotiation
We modeled multi-agent interaction using a structured debate protocol in a hospital triage scenario. This setup allows agents, each with distinct ethical alignments, to negotiate and refine resource allocation decisions, mimicking complex real-world ethical dilemmas.

RAG-Enabled Alignment & Intrinsic Biases
Agents aligned with specific ethical frameworks via Retrieval-Augmented Generation (RAG) demonstrated systematic shaping of negotiation strategies. However, even explicitly aligned LLMs showed persistent intrinsic biases, highlighting the need for systemic solutions beyond individual model alignment.

Practical Solutions to a Theoretical Limit
Arrow's Impossibility Theorem posits that no aggregation mechanism can satisfy all desiderata of collective rationality simultaneously. Our work demonstrates that multi-agent deliberation doesn't resolve this impossibility but successfully navigates it through negotiation, achieving fairer outcomes in practice.
Case Study: Navigating Arrow's Impossibility in Resource Allocation
Problem: Traditional aggregation mechanisms cannot simultaneously satisfy all collective rationality desiderata (Arrow's Impossibility Theorem). This poses a fundamental challenge for achieving universally fair outcomes in resource allocation.
Approach: Multi-agent deliberation provides a procedural mechanism to navigate this constraint, achieving Pareto-improving compromises through structured debate and contestation, rather than resolving it with a perfect rule.
Outcome: Fairness emerges as a property of the collaborative process, not of any individual agent, allowing systems to reach outcomes that are collectively fairer despite inherent theoretical limits.
