Black sheep effect and the identification with group
Previous research has suggested that the black sheep effect – i.e. ingroup derogation – mainly occurs in members highly identified with groups or belonging to highly entitative groups. The present study considered the conjoint effect of identification and entitativity on the ingroup derogation, and in particular considering he moderation role of entitativity on the relationship between identification and derogation of ingroup vs outgroup members. A sample of 169 high school students took part in the study. Results showed that deviant ingroup members from high entitativity groups was harshly evaluated especially from highly identified members than outgroup deviant members. At the same time, a deviant from low entitativity group may pose a significant threat to the highly identified members that still use derogation in order to restore a positive image of the group.
