Although there is a considerable amount of talk about transformative power of deliberation on identity, the debate in literature remains highly theoretical in underlying the benefits of deliberative model for EU Integration. So far, little empirical evidence is available on the actual impact of deliberation. Can deliberation enhance European identity? We specifically address this question by using Deliberative polling quasi-experiment that involved random sample of 348 European citizens in two days deliberation on issues of European concern. The comparison of citizens’ sense of belonging to both EU and nation states before and after deliberation, allowed us to explore the effects of deliberation on identity and further test it against the control group. The analyses show that when European citizens are enabled to deliberate on European issues beyond national borders their exclusive national identity decreases and they become more community- minded. The observed transformation of identities is further analyzed in order to explore the relationship between European and national identity. The analyses indicate that even after deliberative treatment in which European identity has been activated the relationship between multiple identities remains compatible.
