Summary and Keywords
In everyday life, we are faced with disparate examples of intergroup bias, ranging from a mild tendency to ingroup favoritism to harsh episodes of discrimination, aggression, and even conflicts between groups. Where do they stem from? The origins of intergroup bias can be traced back to two main motivations, that is, attachment to one’s own group (“ingroup love”) and negative feelings toward outgroups (“outgroup hate”). Although lay people, but also some researchers, see the two motivations as intertwined, growing evidence from different fields (e.g., social psychology, evolutionary psychology, and neuroscience) has indicated that intergroup bias is more often driven by needs of ingroup protection and affiliation, which do not imply outgroup hostility or competitive attitudes. Outgroup hate is instead likely to arise in intergroup contexts characterized by a high degree of enmity. It is important that members of the groups involved, but also external observers, recognize ingroup love as the primary motor of intergroup conflict: the attribution of hate to the outgroup’s behavior renders negotiation and conflict resolution harder while at the same time justifying severe aggression or even annihilation of the opposing outgroup.
In the domain of intergroup communication, an intriguing way through which group members express their ingroup love and outgroup hate is represented by variations of linguistic abstraction and valence in depicting behaviors performed by ingroup or outgroup members. This unintended use of language reveals that group members are more prone to express ingroup love also at a linguistic level. However, specific changes in intergroup relations along variables such as group size, group status, or relative deprivation can give rise to linguistic patterns of outgroup hate.
