Groups split favorably toward their own members and derogate outgroup attributes

Evidence

The first is the tendency for individuals to perceive their own in-group and its members in comparatively positive terms (as being, for instance, more honest, cooperative, fair, and trustworthy). This bias is termed, aptly enough, “in-group bias” (Brewer, 1979). The second is a tendency for individuals to devaluate the attributes, values, and practices of out-groups and their members—a process known as “out-group derogation.” — Roderick M. Kramer, Geoffrey J. Leonardelli, Robert W. Livingston, Social Cognition, Social Identity, and…, 1973
