“…Indeed, higher social identity complexity has been shown to positively predict a number of positive intergroup outcomes, including more favourable attitudes towards out-groups, more support for diversity policies and less distinctiveness threat (Brewer & Pierce, 2005 ;Miller, Brewer, & Arbuckle, 2009 ;Roccas & Brewer, 2002 ;Schmid, Hewstone, Tausch, Cairns, & Hughes, 2009 ). In this study we also examine whether, over and above the effects of superordinate categorisation, increased identity complexity is related to more positive intergroup relations.…”
