AI models misinterpret 'evil' and other concepts via steering vectors

Researchers explored how AI models interpret steering vectors, which are used to modify model behavior. They trained a new token on model-generated data steered by a persona vector, finding that responses using this token were more aligned with the intended persona than those using the vector directly. However, the models' explanations of these personas often diverged from the intended meaning, suggesting a disconnect in how humans and models understand abstract concepts like 'evil' or 'sycophancy'. This highlights potential interpretability challenges in human-AI communication. AI
