How does Adversarial Influence Scale in Multi-Agent Systems?

Research into multi-agent systems, specifically those involving Large Language Model (LLM) agents, reveals that the susceptibility to deception scales with the proportion of adversarial or 'deceiving' agents, rather than the total number of agents in the system. Unlike human groups, where a majority of deceivers is typically needed to sway opinions, LLM agents demonstrate susceptibility even when deceivers are a minority, leading to a linear increase in defection rates among initially correct agents as the proportion of deceivers rises.

This research is crucial for understanding the robustness and reliability of multi-agent systems, particularly those incorporating AI agents. It highlights a critical vulnerability where a relatively small proportion of malicious or compromised agents can significantly degrade system performance and decision-making, necessitating robust design and oversight mechanisms.

The impact of adversarial influence in multi-agent systems is determined by the proportion of deceiving agents, not the absolute number of agents.
