Editor's Synopsis
Valerio Capraro shares findings from a meta-analysis of 106 studies published in Nature Human Behaviour examining the effectiveness of human-AI collaboration. The key finding is striking: on average, there was no synergy between humans and AI working together. Human–AI combinations did not outperform both humans and AI working independently.
Particularly notable is the implication that when AI alone performed well on a task, adding a human to the loop did not improve outcomes. This challenges the widely held assumption that combining human judgment with AI capabilities automatically produces superior results, and raises important questions about how organizations should design their human-AI workflows.
