Google’s AI overviews reinforce some conspiracy theories – new research
A new study shows stronger guardrails on search engines are needed to prevent the spread and legitimisation of conspiratorial beliefs.
A recent study published in Media International Australia reveals that Google's AI-generated search overviews can inadvertently reinforce conspiracy theories. Focusing on two theories—chemtrails and "15-minute cities"—the research highlights the need for stronger safeguards against the spread of harmful misinformation. The study compared AI overviews with conventional search results, finding that queries reflecting conspiratorial beliefs yielded notably different AI summaries compared to regular searches.
While AI generally debunked conspiracy claims for well-established topics like chemtrails, it often only labeled them as "misinformation," without providing substantive rebuttals. For the less established "15-minute cities" case, 12.5% of AI overviews presented false claims as part of a legitimate debate, actively promoting conspiratorial beliefs.
The study also noted that AI-generated snippets sometimes included commercial links, further contributing to the promotion of conspiratorial narratives. Google spokespersons maintain that their AI overviews aim to match web content to search queries, investing heavily in quality and improvement. However, as Google increasingly provides direct answers in AI-generated snippets, the line between search engine and publisher may blur, raising concerns about the company's role in disseminating information.
