Increasing social media use has transformed political participation by creating social cliques and echo chambers, which involve interaction between like‐minded people. This article examines the relationship between online political activity and personal involvement in online identity bubbles. This study is the first to examine this phenomenon using nationally representative data; its data were derived from surveys targeted at 18–74‐year‐old Finns (N = 3,724). Measures included online political activity, the Identity Bubble Reinforcement Scale, and behavioral and demographic factors. The results show that online political activity was positively associated with online identity bubbles. This effect was strong even after controlling for behavioral and demographic factors. In addition to online political activity, general online activity, online network size, and basic sociodemographic background variables explained variation of involvement in online identity bubbles. However, neither political preference nor political interest had a systematic effect on involvement in these bubbles. The findings confirm the theoretical assumption that online bubbles can be captured using subjective survey measures. Political activity appears to be a key factor associated with the strength of the online bubble experience. This finding has significance in the contemporary information society, in which various mundane discussions and cultural disputes become politically tinged.

政治活动在在线身份泡泡形成过程中的作用

越来越多的社交媒体使用通过创建社交集团和回声室来改变政治参与，这些社交集团和回声室涉及志趣相投的人之间的互动。本文研究了在线政治活动与个人参与在线身份泡沫之间的关系。这项研究是首次使用具有全国代表性的数据研究这种现象；它的数据来自定位于18-74岁的芬兰人调查中得出的（ñ = 3,724）。措施包括在线政治活动，身份泡沫强化量表以及行为和人口因素。结果表明，在线政治活动与在线身份泡沫正相关。即使在控制了行为和人口统计学因素之后，这种效果也很明显。除了在线政治活动之外，一般的在线活动，在线网络规模以及基本的社会人口统计学背景变量还解释了参与在线身份泡沫的变化。但是，政治偏好和政治利益都没有对这些泡沫的参与产生系统性影响。这些发现证实了理论上的假设，即可以使用主观调查手段来捕获在线气泡。政治活动似乎是与在线泡沫体验的强度相关的关键因素。这一发现在当代信息社会中具有重要意义，在当今的信息社会中，各种平凡的讨论和文化纠纷在政治上变得淡淡。
