Guardian investigation finds Google AI Overviews gave dangerous health misinformation
A Guardian investigation found Google's AI Overviews displayed false and misleading health information across multiple medical topics. AI summaries gave incorrect liver function test ranges sourced from an Indian hospital chain without accounting for nationality, sex, or age. The feature advised pancreatic cancer patients to avoid high-fat foods, which experts said could increase mortality risk. Stanford and MIT researchers called the absence of prominent disclaimers a critical danger. Google removed some AI Overviews for health queries after the investigation, but many remained active.
