Researchers have developed a new metric, the coupling gain (gamma), to assess the validity of emergent consensus or polarization in LLM agent societies. This metric, measured by perturbing an agent's opinion, is stable across different frontier models and distinguishes between genuine social dynamics and model artifacts. The study found that LLM societies do not spontaneously self-polarize, suggesting polarization is always induced. A diagnostic tool based on initial versus final opinions can separate true averaging from model-prior artifacts, revealing that a previously published "emergent consensus" result may have conflated these two phenomena.
