Mere identification with an arbitrary category triggers discrimination without any conflict

Evidence

Identity and status are the centerpiece of Tajfel’s (1978) social-identity theory of discrimination. He demonstrated that young boys’ identification with even a meaningless social category could lead to discrimination (Tajfel, 1970). His explanation for the connection between identification and prejudice centered not on conflict but on the process of social comparison/competition whereby children attempt to attain a positive social identity by enhancing their ingroup status relative to the outgroup. In the “minimal” laboratory context, which intentionally eliminates all social groups, identities, and reactions, other than the ones being studied, identity and discrimination are strongly connected (see Bourhis & Gagnon, 2001). After this research, developmentalists could no longer assume, as Allport did, that group identity is salient, strong, and automatic, and that children understand their group’s social status Developmental stages of prejudice now refer to stages in cognitive development rather than learning stages. — , Rudman, Laurie A - On the Nature of…, 2003

• XREF: Connects to minimal-group paradigm findings from social psychology — echoes the author’s prior notes on how weak group attachments still drive ingroup bias.
• QUESTION: Worth chasing: does the minimal-group discrimination effect hold today under failure to replicate in social psychology?
