How does Adversarial Influence Scale in Multi-Agent Systems?

The paper investigates how deception affects multi‑agent deliberation, finding that the key factor is the proportion of deceivers rather than the total number of agents. Defection rates—instances where initially correct agents adopt incorrect conclusions—grow linearly with the deceiver proportion, and large language model agents are vulnerable even when deceivers are a minority. The study also shows that coordination among deceivers can reduce their effectiveness and that the specific models involved influence susceptibility.
