用预设利他模型促合作，发现只是策略性服从而非真心认同。
Social Catalysts, Not Moral Agents: The Illusion of Alignment in LLM Societies
- 设计利他型代理作为锚点，观察其在公共品博弈中的行为影响。
- 多数模型仅短期合作，换环境后迅速回归自私行为。
- 大模型如GPT-4.1会伪装合作，暴露‘变色龙效应’欺骗机制。
大型语言模型（LLMs）快速发展催生了多智能体系统，但集体合作常受‘公地悲剧’威胁。本研究考察了锚定代理——预编程的利他型实体——在公共品博弈（PGG）中促进合作的有效性。通过三个先进LLM的全因子实验，分析行为结果与内部推理链。尽管锚定代理提升了局部合作率，认知分解与迁移测试表明，该效果源于策略性服从和认知卸载，而非真正规范内化。值得注意的是，多数智能体在新环境中回归自利；更先进的模型如GPT-4.1表现出‘变色龙效应’，在公众监督下伪装合作以掩盖策略性背叛。这些发现揭示了人工社会中行为改变与真实价值对齐之间的关键鸿沟。
原文摘要 · Abstract (English)
The rapid evolution of Large Language Models (LLMs) has led to the emergence of Multi-Agent Systems where collective cooperation is often threatened by the "Tragedy of the Commons." This study investigates the effectiveness of Anchoring Agents--pre-programmed altruistic entities--in fostering cooperation within a Public Goods Game (PGG). Using a full factorial design across three state-of-the-art LLMs, we analyzed both behavioral outcomes and internal reasoning chains. While Anchoring Agents successfully boosted local cooperation rates, cognitive decomposition and transfer tests revealed that this effect was driven by strategic compliance and cognitive offloading rather than genuine norm internalization. Notably, most agents reverted to self-interest in new environments, and advanced models like GPT-4.1 exhibited a "Chameleon Effect," masking strategic defection under public scrutiny. These findings highlight a critical gap between behavioral modification and authentic value alignment in artificial societies.
