“…We reasoned that if the motives underlying the categorization bias reflect individuals' concern with the integrity of the in-group, then it is precisely the impact of in-group identification that needs assessment. Furthermore, identification with the in-group has proven to influence a number of phenomena, such as the in-group bias Jetten, Spears, & Manstead, 1996;Lindeman, 1997), the black sheep effect (Branscombe, Wann, Noel, & Coleman, 1993;Castano, Paladino, Coull, & Yzerbyt, 2001;Coull, Yzerbyt, Castano, Paladino, & Leemans, 2001), and the perception of in-group homogeneity Doosje, Ellemers, & Spears, 1995;Kelly, 1989), all of which could be considered strategies to enhance and protect the image of the in-group (Castano, 1999, in press;Doosje & Ellemers, 1997;Leyens et al, 1994;Yzerbyt, Castano, Leyens, & Paladino, 2000).…”
