Meta-stereotypes, the stereotypes believed to be held about one’s ingroup by an outgroup, represent barriers to positive intergroup contact. Little is known, however, about factors accounting for meta-stereotypes. Although previous researchers have speculated on conceptual overlap between social projection (perceiving one’s personal attitudes to be commonly held) and meta-stereotypes, these constructs are typically studied separately. We propose the notion that meta-stereotypes can be explained by social projection processes. We examined Whites’ "bias meta-stereotypes" (perceptions that Blacks consider Whites biased) across two studies. Participants projected personal biases onto both their ingroup (Whites) and outgroup (Blacks); in turn, both ingroup and outgroup bias perceptions uniquely predicted bias meta-stereotypes. Overall, the positive relation between personal bias perceptions and bias meta-stereotypes was fully mediated (i.e., explained) by heightened perceptions of ingroup (White) and outgroup (Black) bias. Overall, there is considerable value in integrating basic social projection within intergroup domains, particularly with regard to meta-stereotyping.
