Abstract
Past research has shown that a heterogeneous (vs. homogeneous) ingroup identity can lead to more outgroup derogation amongst people high on conservative values (Roccas and Amit, 2011) and group identification (Falomir-Pichastor and Frederic, 2013). In three studies we tested the hypotheses that a heterogeneous ingroup identity leads to greater derogation towards immigrants among nationals’ high on RWA, and when immigrants constitute a homogeneous (vs. heterogeneous) outgroup. In all studies we assessed RWA. We manipulated the heterogeneity (vs. homogeneity) of ingroup identity in Studies 1–2 and kept the heterogeneous condition constant in Study 3, we also manipulated outgroup heterogeneity (vs. homogeneity) in Studies 2–3. Finally, outgroup derogation was assessed through two different prejudice scales (Studies 1–2) and an intergroup discrimination scale. Results provided consistent evidence in support of the hypotheses. We discuss the implications of these findings regarding social identity theory and intergroup relations.
Highlights
Past research has shown that a heterogeneous ingroup identity can lead to more outgroup derogation amongst people high on conservative values (Roccas and Amit, 2011) and group identification (Falomir-Pichastor and Frederic, 2013)
The analysis revealed a significant main effect of Right Wing Authoritarianism (RWA), B = –0.39, t(79) = –2.33, p = 0.023, CI = [–0.73, –0.06], ηp2 = 0.07, such that the higher participants scored on RWA the less they personally perceived Swiss national identity to be heterogeneous
The analysis revealed a significant main effect of RWA, B = –0.40, t(74) = –2.47, p = 0.016, CI = [–0.73, –0.08], ηp2 = 0.08, such that the higher participants scored on RWA the less they perceived Swiss national identity to be heterogeneous
Summary
Past research has shown that a heterogeneous (vs. homogeneous) ingroup identity can lead to more outgroup derogation amongst people high on conservative values (Roccas and Amit, 2011) and group identification (Falomir-Pichastor and Frederic, 2013). Ingroup heterogeneity may increase outgroup derogation, at least among those group members who are motivated to maintain clear and distinctive ingroup boundaries. A heterogeneous (vs homogeneous) ingroup identity leads to more outgroup derogation amongst people high on conservative values (Roccas and Amit, 2011) and among high identifiers (Falomir-Pichastor and Frederic, 2013)
