论文摘要
在线平台是否有助于消费潜在有害内容？使用2020年从代表性样本招募的参与者提供的配对行为和调查数据（n = 1,181），我们表明，YouTube上对替代性和极端主义渠道视频的接触大量集中在一小群人的性别和种族偏爱的人中。这些观众通常会订阅这些渠道（提示他们的视频建议），并遵循与他们的外部链接。相比之下，非订阅者很少看到或遵循这些渠道的视频的建议。我们的发现表明，YouTube的算法并未在2020年的观察窗口期间将人们降低“兔子孔”，这可能是由于该公司在2019年对其推荐系统所做的变化。但是，该平台在促进专门的受试者中促进替代性和极端渠道的内容方面继续发挥关键作用。
Do online platforms facilitate the consumption of potentially harmful content? Using paired behavioral and survey data provided by participants recruited from a representative sample in 2020 (n=1,181), we show that exposure to alternative and extremist channel videos on YouTube is heavily concentrated among a small group of people with high prior levels of gender and racial resentment. These viewers often subscribe to these channels (prompting recommendations to their videos) and follow external links to them. In contrast, non-subscribers rarely see or follow recommendations to videos from these channels. Our findings suggest YouTube's algorithms were not sending people down "rabbit holes" during our observation window in 2020, possibly due to changes that the company made to its recommender system in 2019. However, the platform continues to play a key role in facilitating exposure to content from alternative and extremist channels among dedicated audiences.
