The term polarization is used to describe both the division of a society into opposing groups (political polarization), and a social psychological phenomenon (group polarization) whereby people adopt more extreme positions after discussion. We explain how group polarization underpins the political polarization phenomenon: Social interaction, for example through social media, enables groups to form in such a way that their beliefs about what should be done to change the world-and how this differs from the stance of other groups-become integrated as aspects of a new, shared social identity. This provides a basis for mobilization to collective action.
“两极分化”一词用于描述社会分裂为对立群体（政治两极分化），以及一种社会心理现象（群体极化），即人们在讨论后会采取更极端的立场。我们解释了群体极化如何支撑政治两极分化现象：社会互动，例如通过社交媒体，使群体得以形成，其关于应如何改变世界的信念——以及这与其他群体立场的差异——成为新的、共享的社会身份的一部分。这为动员采取集体行动提供了基础。
