EmpiricalRequires evidence

In a preregistered experiment with professional radiologists (Agarwal, Moehring, Rajpurkar & Salz, NBER w31422), giving radiologists AI predictions did not improve their average performance, while giving them contextual information the AI lacked did. The authors attribute the missing gain to belief-updating errors: radiologists underweighted the AI and treated its prediction and their own read as independent. On their estimates, unless those errors are corrected, the best design sends each case to the human or to the AI, and rarely to an AI-assisted human.

    Results show that providing (i) AI predictions does not improve performance on average, whereas (ii) contextual information does. Radiologists do not realize the gains from AI assistance because of errors in belief updating – they underweight AI predictions and treat their own information and AI predictions as statistically independent. Unless these mistakes can be corrected, the optimal human-AI collaboration design delegates cases either to humans or to AI, but rarely to AI assisted humans.
