In this paper, we review the concept of collective narratives and their role in shaping group behaviour. We see collective narratives as ‘meta-stories’ embraced by groups that incorporate values and beliefs about social reality, therefore providing a blueprint for group norms which, in turn, inform group members' behaviour. Our aim is to both describe the psychological processes underpinning the relation between collective narratives and group behaviours and develop an integrative typology of the functions of collective narratives (as they connect to various collective behaviours). We start by discussing definitions in the recent literature and propose an integrative conceptualisation which positions collective narratives in the context of collective action research. Next, we focus on the process by which collective narratives provide the bases for identity formation, development, and change, thus shaping group behaviour. We see collective narratives as central in understanding group behaviour, as they function as ‘meta-stories’ that incorporate moral codes and values, and beliefs about the ingroups and outgroups—providing a blueprint for group norms which, in turn, inform group members' behaviour. In the second part of the article, we describe a typology of collective narratives according to their functions, structured around two core dimensions: the context/s in which collective narratives develop and are shared (i.e., intragroup vs. intergroup) and their effects within these contexts (i.e., driving consensus vs. driving dissent). We identify four distinctive types of collective narrative functions and review research showing how each of them shapes specific social identity content, including behaviour prescribing norms. We then show how these specific norms shape behaviours ranging from cooperation and pro-social action to hostile intergroup conflict. The implications of this contribution are twofold. First, by providing a systematic account and categorisation of how collective narratives function in society and of their connections to social identities (and their content), we can more accurately deduct group norms and predict behaviours in specific circumstances, including in relation to political violence. Second, by better understanding the narratives that provide the bases of identity formation, development, and change, we can improve attempts to create alternative narratives that unify rather than divide people, so that pathways to co-operation might be chosen over conflict.

从合作到冲突：集体叙事在塑造群体行为中的作用

在本文中，我们回顾了集体叙事的概念及其在塑造群体行为中的作用。我们将集体叙事视为群体所接受的“元故事”，这些故事包含了关于社会现实的价值观和信仰，因此为群体规范提供了蓝图，进而为群体成员的行为提供信息。我们的目标是描述支撑集体叙事和群体行为之间关系的心理过程，并发展集体叙事功能的综合类型学（因为它们与各种集体行为相关联）。我们首先讨论最近文献中的定义，并提出一个综合概念化，将集体叙事置于集体行动研究的背景下。下一个，我们关注集体叙事为身份形成、发展和改变提供基础的过程，从而塑造群体行为。我们将集体叙事视为理解群体行为的核心，因为它们作为“元故事”发挥作用，包含道德准则和价值观，以及关于内群体和外群体的信念——为群体规范提供蓝图，进而为群体成员提供信息。行为。在文章的第二部分，我们根据其功能描述了集体叙事的类型学，围绕两个核心维度构建：集体叙事发展和共享的背景（即群体内与群体间）及其在内部的影响。这些背景（即，推动共识与推动异议）。我们确定了四种不同类型的集体叙事功能，并回顾了研究表明它们如何塑造特定的社会身份内容，包括行为规范。然后，我们展示了这些特定规范如何塑造从合作和亲社会行动到敌对群体间冲突的行为。这种贡献的含义是双重的。首先，通过对集体叙事如何在社会中发挥作用以及它们与社会身份（及其内容）的联系提供系统的描述和分类，我们可以更准确地推断群体规范并预测特定情况下的行为，包括与政治暴力有关的行为。其次，通过更好地理解为身份形成、发展和变化提供基础的叙述，
