People in the UK have been shown consistently to hold amongst the least favourable attitudes towards European integration across the whole of the EU. They are also found to be the citizens who are least well-informed about European issues and, in contrast to their European counterparts, they continue to show a high level of resistance towards the possibility of a European identity. A considerable body of research has linked these latter findings with the former, proposing that widespread opposition towards closer integration with the EU (namely via economic and monetary union with the twelve ‘Euroland’ states) is to be understood as a product of apathy and ignorance and reluctance to endorse the ideological project of the European Union. The present research explores this idea by proposing a theoretical framework for understanding how involvement and identity might interact together to influence attitude formation and change. The Elaboration Likelihood Model of persuasion (Petty and Cacioppo, 1981; 1986) provides the basis for this model, proposing that the process by which an individual appraises his/her attitude in response to a persuasion attempt is moderated by their level of involvement in the issue and their motivation to engage with the information with which they are presented. It is hypothesised that the likelihood that national identity will act as a peripheral cue for the formation of attitudes relating to the euro will be dependent on involvement (i.e. levels of knowledge about and interest in the euro issue). This paper reports the findings of an online survey of British students, which employed an experimental design, randomly allocating respondents to different conditions which allowed the investigation of the impact information and identity on attitudes, at varying levels of involvement.
