A YouTube feature designed to stop the spread of misinformation became a major source of confusion on April 15. Multiple YouTube viewers tracking the devastating fire at the Notre-Dame Cathedral in Paris reported that live streams and news videos were displaying an information panel related to the September 11 terror attacks in the United States.
YouTube’s algorithm automatically determines when a subject is trending news and attaches an information panel automatically. The information panel feature is available only in the US and South Korea, and it is meant to provide news from verified sources and counter videos that share conspiracy theories and false narratives.
There have been no reports of the Notre-Dame Cathedral fire being a terrorist attack, so it’s unclear why YouTube would link the two events.
