The literature consistently shows a moderate negative association between educational attainment and anti-immigration attitudes. Yet, we know very little about the factors that explain this association. This working paper draws on extant literature exploring the factors that explain anti-immigration attitudes and how these factors are related to education. Using data from the European Social Survey (ESS), it tests the validity of a causal model linking education to anti-immigration attitudes. The statistical analysis shows that universalism, political interest, and social trust are the strongest mediators of the effect of educational attainment. These findings sustain a narrative according to which the educational system instills universalistic values in students, enhances their interest in politics, and provides them with the skills necessary to navigate social interactions in this very complex world. These qualities then enhance their social skills and make them more trustful of others, including migrants.
