Do Emergent Misalignment Models Share a Circuit?

Fine-tuning language models on narrowly defined harmful tasks can induce emergent misalignment (EM) across unrelated domains.

Key points

  • While prior work has identified shared misalignment-associated representations across independently fine-tuned models, it remains unclear whether these models rely on common computational components.
  • Using direction-based activation tracing, we identify three attention-head locations shared among the five highest-ranked heads of all three organisms.
  • Cross-organism activation transfer further shows that the shared heads exhibit partially interchangeable effects on fixed-response preference.
  • These findings provide evidence that representational convergence in EM extends to shared, causally relevant attention-head components within a common model architecture.
