Ingroup preference need not translate into any particular attitude toward outgroups

Evidence

Let us conclude this section by returning to the distinction between negative intergroup attitudes and ingroup bias. Consistent with the “positive distinctiveness” postulate of Social Identity Theory, most of the research reviewed above focused on “bias” as a dependent variable, which only demands that the ingroup be seen or treated better than the outgroup. However, such measures may only speak indirectly to those manifestations of prejudice which involve some explicit derogation of or hostility toward an outgroup. As Brewer (1979) pointed out some years ago, most ingroup bias phenomena involve a relative overevaluation of the ingroup (or its products) and not a devaluation of the outgroup (and its products). Allport himself also underlined the importance of this distinction: “what is alien is regarded as somehow inferior, less “good,” but there is not necessarily hostility against it” (1954/1979, p. 42). — John F.
