Evidence

As a general definition, intergroup threat occurs when one group’s actions, beliefs, or characteristics challenge the goal attainment or well-being of another group. To date, although a number of separate studies support the importance of intergroup threat for understanding the etiology ofintergroup bias (for reviews of specific types of threats see J. Jackson, 1993; Sears & Henry, 2003) no systematic, quantitative review of this literature has been conducted. — Blake M. Riek, Eric W. Mania, and Samuel L.
