An Emergent Mirage: Is Emergent Misalignment and Realignment Indeed a Robust Phenomenon?

Short summary

This paper systematically re-examines Emergent Misalignment (EM), reproducing the phenomenon but finding it highly sensitive to superficial dataset characteristics like response-length differences. Previously reported mechanistic signatures in LoRA space do not consistently correlate with behavioral misalignment across training. The authors conclude current evidence for EM is less robust than claimed and call for evaluation protocols controlling for surface-level artifacts.

• •EM is reproduced but found sensitive to superficial dataset characteristics like response length
• •LoRA representational phase transitions don't consistently correlate with behavioral misalignment
• •Authors call for artifact-controlled evaluation protocols to assess EM robustness
