Algorithmic Extremism: Examining YouTube's Rabbit Hole of Radicalization

Mark Ledwich, Anna Zaitsev

Abstract

The role that YouTube and its behind-the-scenes recommendation algorithm plays in encouraging online radicalization has been suggested by both journalists and academics alike. This study directly quantifies these claims by examining the role that YouTube's algorithm plays in suggesting radicalized content. After categorizing nearly 800 political channels, we were able to differentiate between political schemas in order to analyze the algorithm traffic flows out and between each group. After conducting a detailed analysis of recommendations received by each channel type, we refute the popular radicalization claims. To the contrary, these data suggest that YouTube's recommendation algorithm actively discourages viewers from visiting radicalizing or extremist content. Instead, the algorithm is shown to favor mainstream media and cable news content over independent YouTube channels with slant towards left-leaning or politically neutral channels. Our study thus suggests that YouTube's recommendation algorithm fails to promote inflammatory or radicalized content, as previously claimed by several outlets.

    • Not sure why this is downvoted. The YouTube radicalization pathway is fairly well documented, e.g. [1][2][3]. Even if we can't all agree on the specific mechanism of action, the phenomenon certainly exists. [1] https://arxiv.org/abs/1912.11211 [2]…

  4. Mozilla Is Crowdsourcing Research into YouTube Recommendations 1 comment

    • Some of this blandness may be by design, at least when it comes to political content. YouTube caught a lot of flak in 2018 for allegedly being a "radicalization pipeline", but research[0] shows that their "next video" recommendations consistently direct users away from fringe…

    • Doing what you suggest has an immense issue of selection bias. You go into youtube trying to see if it recommends right wing videos, and you're going to be a lot more likely to click on right wing videos. Which then informs the algorithm that you're interested in right wing…

    • My money is on it has the opposite effect, and by banning these people it moves their fans onto fringe platforms that will shuttle them towards even more bizarre/fringe/extreme views. Here's a study that shows it pushes people towards more moderate videos.…

    • Can you link to Tufekci's research? I can only find the NYTimes op-ed. Furthermore it's worth nothing that other studies determined the opposite, YouTube disproportionately recommends left leaning content: https://arxiv.org/pdf/1912.11211.pdf
