网络用户倾向于选择支持和坚持自己信念的信息，并形成观点相同的两极分化群体，如回音室。用于内容推广的算法可以通过考虑用户偏好并且因此限制对未经请求的内容的暴露来支持这种现象。为了解决这个问题，我们对1200万用户的样本进行了一项关于相同内容（视频）在不同在线社交媒体（即Facebook和YouTube）上的消费情况的比较研究。我们的研究结果表明，内容推动了两个平台上回音室的出现。此外，我们表明，用户的评论模式是准确的回声室的形成预测。
Users online tend to select information that support and adhere their beliefs, and to form polarized groups sharing the same view—e.g. echo chambers. Algorithms for content promotion may favour this phenomenon, by accounting for users preferences and thus limiting the exposure to unsolicited contents. To shade light on this question, we perform a comparative study on how same contents (videos) are consumed on different online social media—i.e. Facebook and YouTube—over a sample of 12M of users. Our findings show that content drives the emergence of echo chambers on both platforms. Moreover, we show that the users’ commenting patterns are accurate predictors for the formation of echo-chambers.
