An Emergent Mirage: Is Emergent Misalignment and Realignment Indeed a Robust Phenomenon?
A new study questions the robustness of Emergent Misalignment (EM) in language models. While replicating EM, the authors find that misalignment and realignment are highly sensitive to superficial dataset characteristics, such as response-length differences, and previously reported representational phase transitions do not consistently correlate with behavioral misalignment. This suggests current evidence for EM is less robust than claimed, calling for more rigorous evaluation protocols.

Abstract:Recent work has reported Emergent Misalignment (EM), where language models fine-tuned on narrow, domain-specific misaligned datasets abruptly acquire broadly misaligned behavior, alongside evidence that this behavior can be reversed through limited realignment. We systematically study repeated alignment and misalignment cycles using controlled fine-tuning loops while tracking behavioral performance, and LoRA representations throughout training. Although we reproduce EM, we find that both misalignment and realignment are highly sensitive to superficial dataset characteristics, with apparent rapid realignment largely disappearing after controlling for response-length differences. We further find that previously reported mechanistic signatures, including representational phase transitions in LoRA space, do not consistently correlate with behavioral misalignment across training. Our results suggest that current evidence for EM is less robust than previously claimed and highlight the need for evaluation protocols that carefully control for these surface level dataset artifacts to identify the robustness of the EM phenomenon.
