A superordinate identity reduces bias and facilitates intergroup cooperation. This suggests that getting European Union (EU) citizens to identify with Europe will decrease outgroup hostility. Is European identity thus a superordinate identity? Using Eurobarometer data, I determine which level of identification is the most inclusive for individuals' immigration attitudes. Those who feel European hold more favorable views toward immigrants—an effect that is amplified under conditions of cross-cutting cleavages and where country length of European Union membership is greatest. In contrast, strong national identity is associated with more negative immigration attitudes; regional identity has no effect. A subsequent test confirms that the benefits of identifying with Europe extend most strongly to immigrants of European Union origin, although positive effects are observed toward non-European Union migrants as well.
