Preregistered experiment on salience of policy dimensions in the EU and the Russian invasion of Ukraine

This is a pre-analysis plan for an experiment, carried out by YouGov on behalf of a team based at the European University Institute, Florence (IT). The experiment is part of a survey that will be administered to respondents in 5 EU countries. The survey experiment aims to test the salience of two logics of polity building in the EU (social security vs. external threat) in the wake of the Russian invasion of Ukraine. (2022-12-16)
