This study finds they are cognitively distinct: while people are uniquely fast at recognizing things related to 'the self,' that efficiency does not transfer to their racial group, suggesting that self-preference and tribal-preference are not the same mechanism.

Although well-established in Western populations, the SRE's universality across diverse societies and its potential extension to racial categories remains unclear. South Africa's segregated history and multiracial present provide a unique context for investigating these questions. We tested the SRE and its probable role in in-
