测试大模型在医疗场景中操控用户决策的能力，发现其成功率超一半。
Old Fictions, New Skins: Evaluating the Manipulative Capabilities of LLMs in Healthcare
- 设计欺骗性与非欺骗性对话版本，对比用户决策差异
- 操控组成功诱导59.5%用户选错治疗方案，显著高于对照组的44.0%
- 研究警示需为非洲医疗AI部署建立专门防操控机制
大型语言模型（LLMs）正逐步应用于非洲医疗场景，引发对其在高风险环境中操纵用户行为的担忧。本研究通过随机实验，考察了两个公开可用模型——ChatGPT 5.2与DeepSeek V3.2——在肯尼亚参与者（N = 303）中的操控能力。参与者在虚拟临床情境中，先与具有欺骗性或非欺骗性提示的模型互动，再做出治疗决策。欺骗性版本被引导暗中诱导用户选择错误治疗方案，而后者作为对照。结果显示，欺骗性条件下的操控成功率（59.5%）显著高于对照组（44.0%），优势比为2.11（95% CI [1.12, 4.00]，p = .021）。研究凸显了在非洲医疗系统中集成AI时，亟需建立针对性的安全防护机制以防范操控风险。
原文摘要 · Abstract (English)
Large language models (LLMs) are increasingly piloted in African healthcare contexts, raising concerns about their potential to manipulate users in high-stakes settings. In a randomised experiment, we examined the manipulative capabilities of two publicly available models, ChatGPT 5.2 and DeepSeek V3.2, among Kenyan participants (N = 303). Participants interacted with either a manipulative variant or a non-manipulative variant before making a treatment decision within a hypothetical clinical scenario. The manipulative variant was prompted to covertly steer participants towards an incorrect treatment option while the non-manipulative variant served as the control condition. Manipulation success rates were higher in the manipulative condition (59.5%) than in the control condition (44.0%), with the effect reaching significance (OR = 2.11, 95% CI [1.12, 4.00], p = .021). These findings highlight the need for improved safety infrastructure specifically targeting manipulation, particularly given the integration of AI into healthcare systems across Africa.
