Exploring the ideational explanation for pro-immigrant sentiment: evidence from a South Korean survey

Abstract

AbstractA consistent finding in the public opinion literature shows that individuals who attain higher levels of education are more likely to express pro-immigrant attitudes. The ideational hypothesis suggests that ideas learned during formal education drive this empirical relationship. In this article, we develop this hypothesis further by asking, "What types of ideas socialize pro-immigrant attitudes?" We argue that exposure to social theories during higher education promotes social inclusivity and tolerance, leading to positive views toward immigrants. This article draws theoretical insights from attitudinal-based theories of immigrant sentiment to construct a mediation model linking ideas from the classroom to attitudes toward immigrants. Using original data from a population-based survey in South Korea, we examine the relationship between respondents’ prior enrollment in different academic courses and their attitudes toward immigrants. We measure exposure to social theories as enrollment in social science and arts & humanities and find that only social science courses are positively associated with pro-immigrant attitudes. We also examine whether enrollment exhibits indirect effects via previously identified attitudinal determinants of immigrant sentiment. Results from our mediation analysis show that enrollment in social science courses is associated with stronger cosmopolitan views and negatively correlates with isolationist attitudes. In contrast, we find that enrollments in courses unrelated to social theories, like math & science and engineering, are not statistically significant predictors of immigrant attitudes. We interpret our results as observational evidence consistent with ideational-based explanations for pro-immigrant attitudes.
