AI-Assisted vs human-only evidence review Results from a comparative study

Summary

The challenge addressed is the laborious and time-consuming nature of evidence reviews and the uncertainty regarding AI's ability to speed up this process without compromising quality. The Behavioural Insights Team (BIT) conducted a comparative study, producing two rapid evidence reviews on the same topic—one human-only and one AI-assisted—to assess the robustness and reliability of using generative AI. The study concluded that the AI-assisted review was completed 23% faster with similar quality, indicating AI's potential to enhance rapid evidence reviews despite still requiring manual verification for errors.
