<35%
of users identified the right condition
What the research found
In a randomised study of about 1,300 UK participants, people using AI chatbots to self-diagnose identified the relevant condition less than 35% of the time — no better than using an internet search. Strikingly, the models performed better on their own than in the hands of a worried person.
