Often leaders who attempt to enact large-scale changes face resistance from group members who perceive the change as a drastic alteration of the core identity features of their group. Core changes to a group's identity can create a sense of collective identity discontinuity, indicating the group's sense of “who we are” is fundamentally altered. Leaders can circumvent this by emphasizing how the proposed change is consistent with the group's identity, although this may be influenced by whether group members are uncertain and perceive the leader as group prototypical. Two preregistered studies measured the degree to which participants felt self-uncertain and perceived their in-group political party leaders (Study 1) and newly reelected Prime Minister Justin Trudeau (Study 2) as group prototypical and as promoting collective identity continuity before (N = 408) and after (N = 209) the 2019 Canadian General Election. Study 1 results supported the preregistered hypotheses, and Study 2 extended these findings by exploring the hypothesized interaction from Study 1 in the postelection context. We discuss these results in the social identity framework, implicating the importance of a leader's promotion of collective identity continuity in promoting change during uncertain times.

在 2019 年加拿大大选中通过保护群体身份引领变革

通常，试图实施大规模变革的领导者会面临群体成员的抵制，他们认为变革是对他们群体核心身份特征的剧烈改变。一个群体身份的核心变化会产生一种集体身份的不连续感，这表明该群体对“我们是谁”的感觉发生了根本性的改变。领导者可以通过强调提议的改变如何与团队的身份相一致来规避这一点，尽管这可能会受到团队成员是否不确定以及是否将领导者视为团队原型的影响。N = 408) 和之后 ( N = 209) 2019 年加拿大大选。研究 1 的结果支持预先登记的假设，研究 2 通过探索研究 1 在选举后背景下的假设相互作用来扩展这些发现。我们在社会认同框架中讨论这些结果，暗示领导者促进集体认同连续性对于在不确定时期促进变革的重要性。
