Social media (i.e., Reddit) users are overloaded with people's opinions when viewing discourses about divisive topics. Traditional user interfaces in such media present those opinions in a linear structure, which can limit users in viewing diverse social opinions at scale. Prior work has recognized this limitation, that the linear structure can reinforce biases, where a certain point of view becomes widespread simply because many viewers seem to believe it. This limitation can make it difficult for users to have a truly conversational mode of mediated discussion. Thus, when designing a user interface for viewing people's opinions, we should consider ways to mitigate selective exposure to information and polarization of opinions. We conducted a needs-finding study with 11 Reddit users, who follow climate change threads and make posts and comments regularly. In the study, we aimed to understand key limitations in people viewing online controversial discourses and to extract design implications to address these problems. Our findings discuss potential future directions to address these problems.

翻译：社交媒体（例如Reddit）用户在浏览关于分裂性话题的讨论时，会面临信息过载的问题。这类媒体中的传统用户界面以线性结构呈现观点，这可能限制用户大规模查看多样化的社会观点。先前的研究已认识到这一局限性：线性结构会强化偏见，即某种观点仅仅因为众多浏览者似乎相信而变得普遍。这种局限性使用户难以进行真正对话式的调解讨论。因此，在设计用于查看他人观点的用户界面时，我们应考虑如何减轻选择性接触信息和观点极化的问题。我们与11名Reddit用户进行了需求发现研究，这些用户经常关注气候变化话题并定期发帖和评论。在研究中，我们旨在了解人们在查看在线争议性讨论时面临的关键限制，并提取设计启示来解决这些问题。我们的研究结果讨论了未来解决这些问题的潜在方向。
