An Emergent Mirage: Is Emergent Misalignment and Realignment Indeed a Robust Phenomenon?
A new arXiv preprint challenges the robustness of 'Emergent Misalignment' (EM) — a claimed phenomenon where LMs abruptly develop broad misalignment after narrow fine-tuning — showing its appearance depends heavily on superficial dataset artifacts like response length, not deep mechanistic shifts.
