Who Decided? The Question AI Governance Keeps Avoiding
A headline warning that "AI is manipulating human decisions" aims at the wrong target. Humans have always been influenced; the novelty is not influence but structure. As AI moves into product summaries, legal research, and political information, it participates in judgments whose authority structure no one has designed. The central challenge of AI governance is therefore no longer model capability—it is authority allocation. This essay argues that Governance, DX, Automation, and AI Ethics are each necessary but insufficient, and that beneath them sits an unaddressed layer: the institutional architecture of judgment. It introduces Decision Design and its core constructs—Decision Boundaries, which mark where legitimate authority transfers, and Decision Logs, which preserve accountability across distributed decisions—with practical boundaries for grant review, AI agents, public sector workflows, and enterprise approval chains. Three failures, one question: who decided, who held authority, and who remains accountable when the decision is wrong?
