Suppression and justification processes to reduce in-group bias in a multiculturalism diversity context

IntroductionThis study investigates the impact of an organisational multiculturalism perspective of diversity on in-group bias towards people of foreign origin.ObjectiveWe hypothesise that organisational multiculturalism constitutes a norm which creates a positive context for intergroup relations. We expect that when workers perceive that their organisation recognises group differences, their own values are influenced, namely egalitarian values and perceived value violation. The value-related mediators are conceptualised in the frame of justification-suppression model (Crandall & Eshleman, 2003) respectively as suppression and justification.MethodData were collected from a sample of 402 workers who completed an anonymous questionnaire.ResultsBased on structural equation modelling, results show that the perception of organisational multiculturalism is negatively and indirectly related to in-group bias through both suppression and justification processes.ConclusionThis study highlights that the perception of the normative context of an organisation is related to workers’ attitudes. The results are discussed consistent with the literature on diversity.
