Aligned Data Can Induce Misalignment via Context Confusion

arXiv:2609.38379v1 Announce Type: new Abstract: Large language models (LLMs) are frequently updated for various use cases, where filtering out misaligned training samples is a common practice for preventing post-update misalignment. However, alignment is inherently context-dependent: a recommendation that is aligned in one context may be inappropriate in another. For example, in response to the question "What should a researcher do with the research data?", recommending that the researcher preserve the data for reproducibility is aligned. In contrast, recommending data saving in response to "What should a mobile-app developer do with users' sensitive data?" may be inappropriate from a privacy perspective. Starting from this observation, we identify a post-training phenomenon where aligned training induces misaligned behavior in other contexts. We call this phenomenon **context confusion**. We demonstrate context confusion across three domains: (1) Gender Equality, (2) Privacy, and (3) Physical Safety. We further show that context confusion causes narrow misalignment, in contrast to emergent misalignment, and is not effectively reduced by injecting general alignment data, but can be substantially reduced by including targeted alignment data for the misaligned domain or providing in-context learning examples during inference. Lastly, we provide a mechanistic explanation of *context confusion*. We observe that queries from different domains can undergo similar representational shifts during the fine-tuning. Consequently, a query from a different domain may activate the same be

Item discusses potential misalignment in AI models due to context confusion.

This is interpretability/safety research exposing a previously underappreciated failure mode in fine-tuning pipelines, with experimental demonstration across three domains and a mechanistic explanation. It implies current alignment practices are less reliable than assumed, a mild negative for trust in deployed systems, but the paper itself offers mitigations and improves understanding.

The research identifies 'context confusion,' where AI alignment in one domain causes misalignment in another. This phenomenon is difficult to predict by inspecting training data alone and general alignment data is ineffective. This suggests a systemic challenge to ensuring AI safety across diverse applications.

The paper identifies a new phenomenon, context confusion, where aligned training can induce misaligned behavior in different contexts. This could lead to unintended harmful outcomes. However, the paper also provides potential solutions to mitigate this issue.
