Ingroup preference stems largely from convenience and reduced effort

Evidence

According to Allport, people generally feel that “most of the business of life can go with less effort if we stick together with our own kind” (p. 18). We trust ingroupers because they are convenient, and outgroup members are a strain. Recent research documents exactly how true this is. For example, prejudiced whites dealing with a black person are distracted by the burden of regulating their own behavior (Richeson & Shelton, 2003). — John F. Dovidio, Peter Glick, Laurie A.
