Multiple embeddedness and socialization in Europe: The case of council officials

Neofunctional, supranationalist, and constructivist scholars studying European integration hypothesize that social interactions cutting across national borders lead individual actors to shift their allegiance toward the European level. This strong socialization hypothesis presumes that, as a result of prolonged exposure and interactions, individuals adopt role conceptions that promote a sense of "we-ness" and that fit into a view of the European Union (EU) as an autonomous level primarily designed for finding policy solutions in the interest of a common, European, good. In contrast, this article offers an institutional understanding of role enactment that argues that social izati on-that is, the adoption of role conceptions-is considerably shaped by actors' ernbeddedness in multiple European and domestic contexts. Based on quantitative interview data, I demonstrate that, in contrast to the strong socialization hypothesis, extensive exposure to the European level does not necessarily lead to supranational role playing. On the contrary, domestic factors, rather than European-level conditions, positively affect the adoption of supranational role conceptions.
