Childhood Experiences and Intergroup Biases among Children

Children show signs of intergroup biases from early in development, and evidence suggests that these biases increase through middle childhood. Here we critically review and synthesize the literature on the different types of childhood experiences that have been associated with increases or decreases in childhood intergroup bias. Based on the review, one type of childhood experience stands out as being reliably associated with increased intergroup bias over multiple studies—specific overt messages communicating intergroup conflict with, or negativity from, other groups. Three types of childhood experiences were found to be reliably associated with reduced intergroup bias: (a) structured intergroup contact, (b) explicit education about prejudice, and (c) imagined contact with members of other groups. We highlight the social and policy implications of this work and delineate specific experiences and interventions that might be helpful in ameliorating childhood intergroup biases. We also highlight developmental issues concerning the ways that interventions need to vary to be maximally effective at different ages. Finally, recommendations are offered on key factors to incorporate in childhood intergroup bias interventions, as well as what to avoid when attempting to design such programs due to negative (unintended) consequences. This review attempts to
