检查YouTube上自由基含量的消耗
Examining the consumption of radical content on YouTube
摘要：
尽管相对于其他社交媒体平台，YouTube的研究还不够深入，但它可以说是世界上最大、最具吸引力的在线媒体消费平台。最近，YouTube的规模引发了人们的担忧，即YouTube用户正在通过有偏见的推荐和表面上与政治无关的反觉醒频道的组合而变得激进，这两者都被声称直接关注激进的政治内容。在这里，我们使用一个由30多万美国人组成的代表性小组以及他们在2016年1月至2019年12月期间在YouTube上和YouTube外的个人浏览行为来测试这一假设。使用一组标记的政治新闻频道，我们发现YouTube上的新闻消费主要由主流和中间派来源主导。极右翼内容的消费者虽然比平均水平更投入，但在新闻消费者中所占的比例很小且稳定。然而，反觉醒内容的消费（定义为反对进步的知识分子和政治议程）的受欢迎程度稳步增长，并与平台外极右翼内容的消费相关。我们没有发现任何证据表明，与极右翼内容的接触是由YouTube的系统性推荐引起的，我们也没有发现明确的证据表明反觉醒频道是通往极右翼的门户。相反，YouTube上的政治内容消费似乎反映了整个网络的个人偏好。
英文摘要：
Although it is under-studied relative to other social media platforms, YouTube is arguably the largest and most engaging online media consumption platform in the world. Recently, YouTube's scale has fueled concerns that YouTube users are being radicalized via a combination of biased recommendations and ostensibly apolitical anti-woke channels, both of which have been claimed to direct attention to radical political content. Here we test this hypothesis using a representative panel of more than 300,000 Americans and their individual-level browsing behavior, on and off YouTube, from January 2016 through December 2019. Using a labeled set of political news channels, we find that news consumption on YouTube is dominated by mainstream and largely centrist sources. Consumers of far-right content, while more engaged than average, represent a small and stable percentage of news consumers. However, consumption of anti-woke content, defined in terms of its opposition to progressive intellectual and political agendas, grew steadily in popularity and is correlated with consumption of far-right content off-platform. We find no evidence that engagement with far-right content is caused by YouTube recommendations systematically, nor do we find clear evidence that anti-woke channels serve as a gateway to the far right. Rather, consumption of political content on YouTube appears to reflect individual preferences that extend across the web as a whole.
