Symptom Checkers Should Reduce Uncertainty
DrKavner · x · 2026-07-11
The article discusses how **AI symptom checkers** should be designed: the focus shouldn't be on giving users a more "certain" conclusion, but rather on **reducing uncertainty and anxiety**. The author points out that the diagnostic and triage performance of online symptom checkers varies wildly. A classic BMJ audit showed that the correct diagnosis was ranked first in only **34%** of cases. Consequently, the article argues that even if these tools have a polished UI, they cannot be considered successful if they end up making patients more anxious.
