Why YouTube’s algorithm boosted conspiracy theory videos in the wake of the Parkland shooting

YouTube’s recommendation algorithm has come under scrutiny before, but the recent school shooting in Parkland, Florida, launched a fresh spate of criticism. Following the shooting, the No. 1 trending video on the platform was a clip claiming one of the survivors was an actor. YouTube eventually removed the video, saying it had been misclassified by the company’s systems, and that YouTube would make efforts to fix the larger issues. But the controversy highlights the larger issue of information and truth, amid not only a polarizing political climate but also the era of the social media echo-chamber.
