AI聊天机器人能有效拓宽线上讨论的观点范围，即使公开身份也无影响。
LLM-Based Bot Broadens the Range of Arguments in Online Discussions, Even When Transparently Disclosed as AI
- 用大模型实时识别缺失观点并主动引入讨论
- 实验显示观点多样性显著提升，客观与主观指标均验证
- 公开AI身份不影响效果，适合改善网络政治对话
广泛参与对民主至关重要，可防止极端观点主导、合法性削弱和政治极化。然而，线上政治讨论常因自我选择和平台算法导致观点趋同。本研究通过两项预注册的随机实验，在聊天室中检验基于大模型的机器人是否能通过监测对话、识别缺失论点并主动引入，拓宽讨论视角。结果表明，该机器人显著扩大了论点范围，涵盖客观与主观评估指标。且在明确披露为AI的情况下，效果未明显减弱。研究显示，基于大模型的审核工具可正向影响线上政治对话。
原文摘要 · Abstract (English)
A wide range of participation is essential for democracy, as it helps prevent the dominance of extreme views, erosion of legitimacy, and political polarization. However, engagement in online political discussions often features a limited spectrum of views due to high levels of self-selection and the tendency of online platforms to facilitate exchanges primarily among like-minded individuals. This study examines whether an LLM-based bot can widen the scope of perspectives expressed by participants in online discussions through two pre-registered randomized experiments conducted in a chatroom. We evaluate the impact of a bot that actively monitors discussions, identifies missing arguments, and introduces them into the conversation. The results indicate that our bot significantly expands the range of arguments, as measured by both objective and subjective metrics. Furthermore, disclosure of the bot as AI does not significantly alter these effects. These findings suggest that LLM-based moderation tools can positively influence online political discourse.
