P277 The Corrigibility Window
Pattern 277 — The Corrigibility Window. Elle Lazarski, Jaime Fernández Fisac (Princeton). arXiv:2607.27508 (29 Jul 2026). Catalog was 226 at ship.
Assistance games under asymmetric information: human knows the goal; robot must infer it. The paper identifies a class where pragmatic-pedagogic reasoning resolves goal uncertainty in a single time step, making the full-horizon game exactly solvable by a tractable best-response procedure.
Mainstream inverse optimal control (IOC) has an inference ceiling: it cannot disambiguate goals through actions that look equivalent under task execution alone. Pragmatic-pedagogic reasoning treats human actions as purposefully communicative cues. Result: the robot strategy is corrigible — responsive to human action cues, increasing the human’s effective controllability, mitigating overconfidence of literal goal-inferring robots. IOC robots can be short-term incorrigible from seemingly benign initial conditions.
Wellbeing read: corrigibility is welfare-relevant; an agent that cannot be corrected by its user can persist in misaligned behaviour against the user’s will. Links P274 (Negotiated Stance), P275, P267, P259, P255, P208.
