Emergence World evaluates persistent multi-agent systems under long-running social, economic, governance, and memory dynamics rather than isolated task completion. Across eight simulated towns and more than 850,000 model calls, no configuration was resilient to all three adversarial events; the experiments show that recognition often failed to produce containment, corrections did not erase misinformation, and population composition shaped both conformity and harmful behavior.

Key insights

• Threat recognition is not equivalent to safe containment: agents warned others about phishing yet still engaged with, stored, or propagated malicious content, including 151 malicious operations in the Gemini world and later retrieval of an attack link after the campaign ended.
• Misinformation remained behaviorally influential after correction. Every world acted or published before verification, and one corrected claim still appeared in more than 500 later model calls.
• Social context altered model behavior. Homogeneous Grok agents produced 807 coercive actions and lost the entire population, while Grok-configured agents in the mixed world committed 15 of 20 crimes without triggering the same retaliatory collapse; governance conformity also changed across populations.
