Study finds AI advice reduces accuracy threefold while doubling user confidence

Researchers published a study on the impact of AI advice on decision‑making. Participants who received AI suggestions performed three times worse on accuracy. The same participants reported roughly double the confidence in their answers. The findings indicate AI can suppress critical thinking. The study examined how AI advice influences human judgment. Results raise concerns for AI deployment in high‑stakes contexts. Authors suggest designing AI to encourage verification rather than blind trust. Future work will explore methods to mitigate overconfidence effects.
