AI trials involve governments less often than trials in general
Five researchers tracked AI interventions across two trial registries from 2019 into a partial 2026. AI is on track to make up one in five registered trials, up from one in thirty in under four years, the average planned AI trial runs 11.3 months, and AI trials in the AEA registry are government-related 10.7 per cent of the time against 14.1 per cent for trials overall.
