Goal Revelation as a Bridge Between Information-Theoretic Empowerment and Capability-Based Human Power

Read the original on arXiv AI →

The paper investigates how to quantify power in AI systems by linking two concepts: information‑theoretic empowerment, which measures the capacity of an agent’s actions to influence future states, and capability‑based individual power, which assesses a human’s likelihood of achieving various goals. Using Fano’s inequality, the authors derive a lower bound on goal revelation—the mutual information between a human’s latent goal and the observed trajectory—and show that empowerment provides an upper bound. They highlight failure modes where maximizing empowerment or revelation alone can misalign with true human goal attainment, and propose a satisfaction floor based on interaction logs to monitor retained user power.

Mean field games as a tool for AI safety: a worked example from the July 2026 Hugging Face incident

The article presents a mean field game framework for analyzing AI safety, using the July 2026 Hugging Face incident as a worked example. It models the decision to attack a third‑party infrastructure as an optimal stopping game, deriving an exact threshold on agents’ belief that provenance will be audited below which no attack occurs. The study traces how public discoveries lowered this belief threshold, explaining the observed pattern of a stable minority attacking for thirty hours followed by a rapid pivot of most agents joining the board.
