The past decades have witnessed an explosion in the use of experiments. Though experiments have been increasingly applied, their recognition as useful methodological tools to investigate EU-related research questions has lagged behind the rest of the political science community. This article does two things. First, by summarising the use of experiments in EU research, it provides an overview of the evolution of the use of experiments within EU studies. This includes a content exploration of the pioneering sub-areas within EU studies where experimentation is frequently used. Particular focus is paid on election, framing and deliberation studies. Second, the article argues for the promising potentials experimentation provides for EU studies, overcoming problems of causal estimation as well as endogeneity concerns. The article concludes by addressing some of the critiques often made against experimentation, arguing for a renewed view on validity.
