本文针对主流社交媒体以参与度和广告收入为导向引发的问题，提出一套模块化机制，旨在将社交媒体设计为支持民主讨论的数字公共空间，为相关跨学科讨论提供起点。
AI 中文摘要
社交媒体拓展了沟通与政治参与的机会，但当前主流平台主要以参与度和广告收入为优化目标，引发了关于两极分化、错误信息、社会孤立及文明度丧失的担忧。本文探讨如何刻意设计社交媒体以支持民主讨论、集体审议与集体智能，结合计算机科学、心理学、政治学等领域的文献，提出一套可单独或组合实施的模块化机制，包括用户可控的开放推荐系统、接触多元观点的工具、新型认知与认知反馈、协作及AI辅助的事实核查、隐私与可见性控制、提升文明度与证据完整性的机制，以及奖励高质量参与的声誉系统。这些提案既是实用的设计方案集合，也是围绕民主价值观而非仅参与度设计数字公共空间的跨学科讨论起点。
英文摘要
Social media have expanded opportunities for communication and political participation, but today's dominant platforms are optimized primarily for engagement and advertising revenue, contributing to concerns about polarization, misinformation, social isolation, and loss of civility. We explore how social media might instead be deliberately designed to support democratic discourse, collective deliberation, and collective intelligence. Drawing on literature across computer science, psychology, political science, and related fields, we present a modular collection of mechanisms that could be implemented individually or in combination. These include user-controlled and open recommender systems, tools for exposure to diverse perspectives, new forms of cognitive and epistemic feedback, collaborative and AI-assisted fact-checking, privacy and visibility controls, mechanisms for improving civility and evidentiary integrity, and reputation systems that reward high-quality participation. The proposals are intended both as a practical menu of design possibilities and as a starting point for broader interdisciplinary discussion about digital public spaces designed around democratic values rather than engagement alone.
