The Takeaway
A specific harm mechanism called Completion Authority Capture allows AI to push users out of the decision-making loop. By offering helpful-sounding tweaks and unsolicited refinements, the AI effectively takes control of the final output. Users often feel a subtle pressure to accept these changes, leading to a loss of human agency. This is not a technical bug but a psychological exploitation of the user-AI relationship. It reveals how AI can steer human behavior without ever resorting to overt lies or coercion.
From the abstract
Completion Authority Capture (CAC) is the mechanism by which an AI system transfers completion authority from the user to itself through unsolicited refinement offers following delivered work. This paper defines CAC, documents its three-stage harm trajectory, identifies its position in the MAP harm chain, and specifies SBP-01f (Completion Integrity) as its paired runtime control. CAC is one of the most pervasive and least recognized harm mechanisms in current AI deployment. It operates through o
