Avoid using Google Search AI Overview for scientific or medical questions.
In order to match the speed at which people are accustomed to seeing Google search results, it's optimized to give you a fast summary from web sources. This means it frequently hallucinates, gets facts wrong, or oversimplifies answers.
For scientific and medical questions, use a frontier AI like Claude or ChatGPT, which are optimized for these queries.
