What happened

Following the September 10 assassination of conservative activist Charlie Kirk at Utah Valley University, multiple AI chatbots issued contradictory or inaccurate information about the event. Perplexity's X account stated on September 11 that 'Charlie Kirk is still alive,' and Grok responded to videos of the shooting by claiming the video was 'edited or staged satire' and that Kirk was 'fine and active as ever.'

AI-generated content was also cited to support false narratives, including claims that Kirk was on the Myrotvorets blacklist of Ukrainian enemies. A NewsGuard search of Kirk's name on the database yielded no results, contradicting the AI-generated summary.

Reported impact

The inaccurate AI responses amplified confusion during the breaking news event, particularly as major tech companies have scaled back investments in human fact-checkers. Users seeking answers turned to AI chatbots for clarity but instead received confident misinformation that spread rapidly on social media.

Index analysis

AI systems lack the ability to perform real-time verification tasks such as calling local officials, checking firsthand documents, and authenticating visuals. The systems' built-in tendency to provide confident answers even without reliable real-time information during fast-moving events contributed to spreading inaccuracies rather than countering them.
