This, the result of a months-long investigation by the New York Times, is terrifying: How YouTube radicalised Brazil.
A New York Times investigation in Brazil found that, time and again, videos promoted by the site have upended central elements of daily life.
Teachers describe classrooms made unruly by students who quote from YouTube conspiracy videos or who, encouraged by right-wing YouTube stars, secretly record their instructors.
Some parents look to â€œDr. YouTubeâ€ for health advice but get dangerous misinformation instead, hampering the nationâ€™s efforts to fight diseases like Zika. Viral videos have incited death threats against public health advocates.
And in politics, a wave of right-wing YouTube stars ran for office alongside Mr. Bolsonaro, some winning by historic margins. Most still use the platform, governing the worldâ€™s fourth-largest democracy through internet-honed trolling and provocation.
YouTube continues to deny what’s obvious to everyone: its algorithms prioritise conspiracy theories, right-wing bullshit and any other content that purports to tell you the truth that others are trying to conceal. And that has horrific real-world consequences â€“ to the point where we need to warn parents of the signs that their boys are being radicalised by YouTube gaming commentators.
YouTube’s recommendation of awful content isn’t a bug. It’s feature. The entire system is built to prioritise attention, and what gets the most attention is the most inflammatory, fear-mongering, hateful content.
When even the far right are crediting YouTube with their political successes, it’s clear that YouTube’s protestations mean nothing. Whether it’s spreading anti-vaccine fear or right-wing conspiracies, YouTube has become a cancer at the very heart of modern life.
