赢得争论：善意在线讨论中的互动动力学和说服策略
Winning Arguments: Interaction Dynamics and Persuasion Strategies in Good-faith Online Discussions
摘要：
改变某人的观点可以说是社交互动中最重要的挑战之一。其背后的过程很难研究：很难知道一个人的观点是如何形成的，以及一个人的观点是否会改变，以及如何改变。幸运的是，Reddit上的一个活跃社区ChangeMyView提供了一个平台，用户可以在这里表达自己的观点和推理，邀请其他人提出质疑，并在随后的讨论改变了他们的原始观点时表示认可。在这项工作中，我们研究这些互动，以了解说服背后的机制。我们发现，有说服力的论点的特点是有趣的互动动态模式，如参与者进入顺序和程度的来回交换。此外，通过比较类似的反驳同一意见，我们表明，语言因素起着至关重要的作用。特别是，意见持有者的语言和反驳者的语言之间的相互作用提供了具有说服力的高度预测性线索。最后，因为即使在这种有利的设置，人们可能不会被说服，我们调查的问题，以确定是否有人的意见是容易被改变。对于这个更困难的任务，我们表明，风格的选择，在如何表达的意见进行预测能力。
英文摘要：
Changing someone's opinion is arguably one of the most important challenges of social interaction. The underlying process proves difficult to study: it is hard to know how someone's opinions are formed and whether and how someone's views shift. Fortunately, ChangeMyView, an active community on Reddit, provides a platform where users present their own opinions and reasoning, invite others to contest them, and acknowledge when the ensuing discussions change their original views. In this work, we study these interactions to understand the mechanisms behind persuasion. We find that persuasive arguments are characterized by interesting patterns of interaction dynamics, such as participant entry-order and degree of back-and-forth exchange. Furthermore, by comparing similar counterarguments to the same opinion, we show that language factors play an essential role. In particular, the interplay between the language of the opinion holder and that of the counterargument provides highly predictive cues of persuasiveness. Finally, since even in this favorable setting people may not be persuaded, we investigate the problem of determining whether someone's opinion is susceptible to being changed at all. For this more difficult task, we show that stylistic choices in how the opinion is expressed carry predictive power.
