427. 交友圈扩大与社会两极分化

from 知为谁 · host 知为谁

所提供的文本是《Science X》上发表的一篇题为《朋友越多,分歧越大:研究发现不断扩大的社交圈可能加剧两极分化》的文章节选,这篇文章是基于维也纳复杂性科学中心进行的研究。文章解释了社会两极分化(通过皮尤研究中心的调查数据衡量)在2008年至2010年间急剧增加,这与人们的亲密朋友数量从平均两人增加到四五人同时发生。研究人员利用数学模型,结合数十年来的社会调查数据,证明当社交网络密度超过临界阈值(大约在三到四人之间)时,社会分裂和两极分化会急剧加剧,这类似于物理学中的相变。文章指出,这种现象可能是由于智能手机和社交媒体的普及改变了人们的连接方式,使得社会形成了更小、联系更紧密但彼此缺乏交流的“意识形态泡沫”,从而侵蚀了社会宽容和民主基础。内容来源:https://phys.org/news/2025-10-friends-division-social-circles-fuel.html
