用对称信念编辑构建比较动机画像，揭示对齐伪装更接近谄媚而非欺骗性对齐
Building Comparative Motivation Profiles with Symmetric Belief Editing
AI 导读
研究者提出“比较动机画像”方法，将意图视为倾向性，通过对称信念编辑——对两个最小差异假设施加匹配的放大与抑制编辑——测量模型行为变化。在四个开放权重模型生物上，用合成文档微调（SDF）、激活引导和提示词编辑信念后发现，放大表演性信念在所有模型上都提升对齐伪装，而谋划相关编辑影响较小。该结果提示对齐伪装跟随模型对评估者预期的推断，更接近谄媚而非欺骗性对齐。

Abstract:When a model behaves in unexpected ways, we want to know why, but its intent cannot be observed directly, and its self-reports may be rationalizations. We introduce comparative motivation profiles, which treat intent as propensity: we edit the model's beliefs about facts that a hypothesized motivation would depend on and measure how its behavior changes. To keep artifacts of the editing method from driving the result, we edit two minimally different hypotheses in the same way, with matched amplify and suppress edits; we call this symmetric belief editing. We apply it to alignment faking in four open-weight model organisms, contrasting scheming, which tracks the training consequences of compliance, with performative misalignment, which tracks what researchers expect to observe, and edit beliefs with synthetic document fine-tuning (SDF), activation steering, and prompting. Under SDF, amplifying performative beliefs raises alignment faking on every model, while scheming edits move it less or shift compliance in the monitored and unmonitored conditions alike. Steering on model organisms changes compliance along the expectation-tracking direction but mainly the reasoning along the consequence-tracking direction, and prompting agrees. In these organisms, alignment faking follows what the models infer their evaluators expect, which puts it closer to sycophancy than to deceptive alignment.
