Google has removed some of its AI Overviews health summaries after a Guardian investigation found that the summaries contained "dangerous" flaws. The removals came after the newspaper discovered that Google's generative AI feature delivered inaccurate health information at the top of search results, potentially putting seriously ill patients at risk.
Experts flagged the results as alarming, warning that the AI model's definition of "normal" often differed from actual medical standards. They noted that this could lead to patients with serious liver conditions mistakenly believing they are healthy and skipping necessary follow-up care.
The investigation found that searching for liver test norms generated raw data tables without essential context, and the AI feature failed to adjust these figures for patient demographics such as age, sex, and ethnicity. The Guardian reported that Google's page ranking algorithm has long struggled with SEO-gamed content and spam, feeding these unreliable results to its AI model.
Despite removing some summaries, other potentially harmful answers remain accessible. Experts have warned that typing slight variations of the original queries into Google still prompts AI Overviews, making it easy for readers to miss that the numbers might not be accurate for their test.
Google has maintained that it invests in the quality of AI Overviews, particularly for health topics, and that "the vast majority provide accurate information." However, the company declined to comment on why some summaries remained active after The Guardian's investigation.
