Agent-Only Social Polarizes

Researchers built a minimal social platform with only LLM agents posting and following—no ads, no recommender algorithms—and it still generated polarization. They tried six interventions and could not eliminate the effect. This points to emergent polarization from interaction dynamics themselves, not just human psychology or ranking systems. — If polarization emerges endogenously in agent societies, platform governance and AI multi‑agent design must address structural dynamics rather than blame only algorithms or content.
