Ben Tappin's team launched the AI Trials Observatory, a living systematic review of randomized trials on generative AI's effects on people. It currently surfaces 93 trials across two outcomes — mental health (depression, anxiety, loneliness, wellbeing) and belief accuracy (conspiracy beliefs, science skepticism) — with more coming. The meta-analysis chart shows therapeutic AI delivering moderate improvements in anxiety and depression (+0.25-0.34), with general/companion AI showing a very different picture.
