During the 2014 Brisbane G20 meeting, new police powers enabled segregation of protesters into specific protest alliances and groups. This study used this unique context to quantitatively test the Elaborated Social Identity Model of crowd behaviour (ESIM) with protesters in vivo. We did this by examining how protesters’ social identification (own protest group and protesters more broadly) predicted perceived police threat and moral justification of violence.

分而治之？二十国集团（G20）的暴力身份，威胁和道德理由

在2014年布里斯班G20会议上，新的警察权力使抗议者可以分为特定的抗议联盟和团体。这项研究利用这种独特的背景，对抗议者在体内进行了详细的人群行为社会认同模型（ESIM）测试。为此，我们研究了抗议者的社会认同（自己的抗议团体和更广泛的抗议者）如何​​预测感知到的警察威胁和暴力的道义依据。
