Following Self-Categorization Theory, the present study argues that self-st
ereotyping should be considered in examining the relationship between ident
ification and ingroup bias. A study among Iranians living in the Netherland
s was conducted. It was found that identification was related to self-stere
otyping under conditions of group threat. Further, only self-stereotyping m
ade a unique contribution to the explanation of ingroup bias. However, ther
e was an interaction effect showing that self-stereotyping was related to i
ngroup bias for high identifiers. Future studies on ingroup bias are advise
d to examine the role of bath identification and self-stereotyping. Copyrig
