Microsoft's Bing chatbot repeated COVID-19 and other conspiracy theories spouted earlier by ChatGPT, prompting concerns about the spread of disinformation and the erosion of trust in the Internet.

Building on research by anti-misinformation company Newsguard that had found that ChatGPT delivered misleading and false claims about COVID-19, Ukraine and school shootings, Microsoft's Bing (since renamed Microsoft Copilot) chatbot was persuaded to repeat them as responses to questions posed by TechCrunch.

The finding raised concerns about the potential for generative AI systems to feed off each other and to damage the quality of the information ecosystem and trust in public information.
