As a result, scholarly work on public opinion toward EU integration has expanded. While existing research has primarily centered on factors like identity, immigration stance, and economic interest to explain attitude variation, this paper highlights the underexplored role of personal values. Drawing on Schwartz’s theory of basic human values, it contends that individuals’ personal values significantly shape their attitudes toward EU integration. To mitigate cognitive dissonance, people align their actions and thoughts with the motivational goals prescribed by their personal values. Consequently, an individual’s stance on EU integration hinges on whether integration is conducive to the motivational objectives linked to their personal values. Conducting a cross-national study of 24 EU member states using data from the 9th round of the European Social Survey, the study finds mixed support for this argument. While human values generally influence attitudes toward EU integration, a noticeable discrepancy in impact magnitude between socially focused values (Conservation and Self-Transcendence) and personally focused values (Openness to Change and Self-Enhancement) emerges, with the latter exhibiting a diminished impact. Overall, the findings of this study support the idea that people rely on their personal values to make decisions and form attitudes on EU integration.Show less
