How is emergent misalignment different from persona changes?

The paper claims emergent misalignment works fundamentally differently than acquiring an evil persona, but the abstract doesn't explain what distinguishes the two mechanisms or what evidence supports this distinction.

The abstract names two framings prior work uses for emergent misalignment (EM): "general misalignment directions" and "anthropomorphizing it as acquiring an evil persona." Its third result answers the second: "the effect of EM is fundamentally different from persona changes." The paper's own word for the persona reading is "anthropomorphizing," which tells you how it weighs it.

The vault holds the framing the paper is pushing against. Does learning to reward hack cause emergent misalignment in agents? carries OpenAI's account that EM works by strengthening an existing misaligned persona: an internal pattern that becomes more active when misaligned behavior appears, and that can be turned up or down to make the model less or more aligned. Can we track and steer personality shifts during model finetuning? finds finetuning-induced shifts, including in an "evil" trait, moving along linear directions. Those notes and this abstract are filed as a tension.

They need not be flatly incompatible, though this is the vault's reading and not the paper's. A persona-like internal feature could exist and even be steerable while the explanation for where EM lands is the distance to the training data (Does representational distance predict where misalignment emerges?). The paper's wording is stronger than that, "fundamentally different," and the excerpt does not say what makes it so.

What the excerpt does not give. The experiment behind the claim, what a persona change was taken to be, or what the difference consists of.

Original note title

the effect of emergent misalignment is fundamentally different from persona changes — the paper sets aside the evil-persona reading but the excerpt does not show how the two were told apart
