自媒体表达空间所具有的开放性、互动性、多元性等特点,使舆论的形成与发展出现了“发散式螺旋”的变型。在“2·18武昌火车站案”的舆论发展过程中,不同论点从事件中心向不同方向螺旋式推进、发散,最终形成了多元抗衡的舆论场。而在“自我中心化”的发散螺旋中,人们尽情宣泄情绪,却忽略了最核心的新闻事实。 The open, interactive and pluralistic nature of the media expression space has led to the emergence of a “divergent spiral” in the formation and development of public opinion. During the development of public opinion in the “18-18 Wuchang Railway Station Case,” different arguments propelled and diverged in different directions from the event center, and eventually formed a multi-contested media scene. In the divergent spiral of “self-centered ”, people give vent to their emotions without regard to the most central fact of the news.
