Introduction. In this exploratory study, we examined several interethnic ideologies held by individuals (assimilation, colorblindness, multiculturalism, and polyculturalism) from a social ecological perspective. We examined moderation effects of neighborhood ethnic density (ED) on relationships between interethnic ideologies and intergroup bias towards various minority ethnic groups in the Russian context. Intergroup bias was assessed as a composite score of bias toward four ethnic groups who have different cultural distances from the Russian mainstream population: Chechens, Belarusians, Uzbeks, and Chinese. Method. We obtained a gender balanced sample of ethnic Russians from the Central Federal District of Russia (N = 359) comprising of 47% women and 53% men. The measures were used in a Russian translation by an adaptation using the back-translation and cognitive interviews. Multiple regression analysis was used to test the relationships. Results. The results showed that high perceived neighborhood non-Russian ED weakened negative relations between intergroup bias and ideologies that purportedly accept cultural diversity (multiculturalism and polyculturalism). On the other hand, for interethnic ideologies those purportedly reject cultural diversity, high perceived neighborhood non-Russian ED weakened the positive relations between intergroup bias and assimilation and strengthened the negative relations between intergroup bias and colorblindness. Summary and Conclusions. The pattern of results suggests that the relationship between attitudes and intergroup bias may change based on the perceived ethnic composition of the local area and frequency of contacts. Although our findings are relatively novel they support the emerging view that attitudes and intergroup relations need to be studied from a social ecological context.
