Google AI’s Health Advice Misled Users

▼ Summary
– The Guardian’s investigation found health experts identified inaccurate or misleading guidance in some of Google’s AI Overview responses to medical queries, which reviewers called dangerous.
– Google disputes the report, stating the examples were often based on incomplete screenshots and that the vast majority of AI Overviews are factual and helpful.
– Specific examples of errors included incorrect dietary advice for pancreatic cancer patients and dangerous mental health guidance that could deter people from seeking help.
– The investigation notes AI Overviews appear prominently in search results and that medical queries are especially likely to trigger them, amplifying the risk of health misinformation.
– Google has adjusted the feature after past criticism and argues its accuracy is comparable to other search features, while committing to continuous improvements.
A recent investigation has raised significant concerns about the accuracy of health information provided by Google’s AI Overview feature. The report suggests that some AI-generated summaries for medical queries contain misleading or factually incorrect guidance, which experts warn could pose a real danger to individuals seeking health information online. Google disputes these findings, stating the examples presented were based on incomplete screenshots and that the vast majority of its AI Overviews are factual and helpful.
The investigation involved testing a range of health-related searches and sharing the AI Overview responses with medical charities and patient information groups. Reviewers identified several instances of problematic advice. For pancreatic cancer queries, one summary incorrectly advised patients to avoid high-fat foods. A health expert stated this guidance was “completely incorrect” and warned that following it could be dangerous, potentially jeopardizing a person’s ability to withstand treatment.
In the realm of mental health, summaries for conditions like psychosis and eating disorders were found to offer what was described as “very dangerous advice.” Critics noted this incorrect information could lead people to avoid seeking the professional help they urgently need. Another error involved cancer screening, where a pap test was wrongly listed as a test for vaginal cancer, disseminating what a charity chief executive called “completely wrong information.”
A key issue highlighted is the feature’s placement at the very top of search results, which can present inaccurate health information as authoritative. This positioning risks undermining years of effort by medical publishers who invest heavily in documented expertise. Furthermore, the investigation noted a practical verification problem: repeating the same search query can yield different AI summaries at different times, as the system pulls from varying sources, making it difficult for users to confirm what they previously read.
In its defense, Google challenged the report’s examples and conclusions. A company spokesperson argued that from what they could assess, the cited responses linked to reputable sources and included recommendations to seek expert advice. Google maintains it continuously makes quality improvements and that the accuracy of AI Overviews is comparable to other Search features like featured snippets. The company also stated it takes action under its policies when an AI Overview misinterprets web content or lacks proper context.
This scrutiny arrives amid an ongoing debate about the reliability of AI-generated summaries since their broader rollout. Early attention focused on bizarre and nonsensical responses to unusual queries, which prompted Google to refine the system. Recent data analysis indicates that medical queries, which fall into the “Your Money or Your Life” category due to their high stakes, are more than twice as likely to trigger an AI Overview than the average search. Separate research into large language models has pointed to existing issues with citation support, where AI-generated answers are not fully backed by the sources they reference, even when links are provided.
The core concern is that when the topic is health, errors carry far greater consequences. The feature’s dynamic and sometimes inconsistent nature, combined with its prominent placement, creates a unique challenge for ensuring public safety. While Google has previously adjusted AI Overviews following public criticism, its current stance suggests it expects these summaries to be evaluated alongside traditional search results, not held to an entirely separate standard of accountability.
