Responding to self-conceptual uncertainty: Orthodoxy, diversity, and social identity in groups and society

社会上的一些群体以种族为中心，排外，信奉正统、同质性和等级制。他们压制多样性和异议。其他群体拥抱多样性，对同质性和等级制度持谨慎态度。项目探索身份和群体成员的社会心理，回答为什么有些群体是正统的，而另一些群体是多样化的。对群体身份的不确定是令人厌恶的；自动激发对群体的认同，这些群体是具有明确边界、共识属性和同质成员的独特实体。然而，内部多样化的群体也可以是不同的（通常是更好的）实体。对不确定性的自动反应的缓冲可能有利于多样化而不是正统的群体。

Some groups in society are ethnocentric and xenophobic, embracing orthodoxy, homogeneity and hierarchy. They suppress diversity and dissent. Other groups embrace diversity, and are wary of homogeneity and hierarchy. Project explores the social psychology of identity and group membership, to answer the question why some groups are orthodox whereas others are diverse. Uncertainty about one's group identity is aversive; automatically motivating identification with groups that are distinct entities with sharp boundaries, consensual properties, and homogeneous membership. However, internally diverse groups can also be distinct (often better functioning) entities. Buffering of automatic reactions to uncertainty may favour diverse over orthodox groups.
