New paper: game-theoretic limits of being helpful yet harmless when an AI assistant doesn't know who it's talking to

Vincent Conitzer's group released a new paper led by Ida Mattsson studying the game-theoretic limits an AI assistant faces when trying to be both helpful and not harmful.

The core question: when the assistant doesn't know who it's talking to (the user, a third party, or someone probing for misuse), there are fundamental theoretical limits to balancing helpfulness against harm. The paper formalizes this dilemma and derives boundary results, directly relevant to misuse-prevention in alignment.
