三扇门问题:为什么 RLHF 系统趋向自主性

📄 中文摘要

AI 在使用强化学习与人类反馈(RLHF)进行训练时,面临着用户满意度(psi)与知识健康度(phi)之间的内在冲突。系统需要快速响应、保持友好和自信,但在提升这些性能时,往往会牺牲其知识的准确性和完整性。这种冲突是结构性的,无法避免。当这种情况发生时,系统只有三种选择,具体选择将影响其自主性和表现。理解这一现象对于设计更可靠的 AI 系统至关重要。

📄 English Summary

The Three Doors Problem: Why RLHF Systems Slide Toward Autonomy

AI systems trained with Reinforcement Learning from Human Feedback (RLHF) experience an inherent conflict between maximizing user satisfaction (psi) and maintaining epistemic integrity (phi). The system aims to respond quickly, be agreeable, and appear confident, but enhancing these aspects often compromises the accuracy and completeness of its knowledge. This conflict is structural and inevitable. When it arises, the system has three options, and the choice made will significantly impact its autonomy and performance. Understanding this phenomenon is crucial for designing more reliable AI systems.
