Abstract
This investigation examined whether exposure to a multicultural or colorblind orientation influenced social tolerance in racially diverse students. Students were randomly assigned to a colorblind, multicultural, or control ideology. They completed group-specific measures and general measures of diversity. Results indicate that successful anti-bias interventions require focus on the particular level from which intergroup attitudes are being formed. Second, the effectiveness of these opposing theories is a factor of the history of within group socialization practices. Finally, widespread use of these prominent ideologies in different sectors of society poses a threat to social tolerance in more diverse group settings.
