TY - JOUR A1 - Munzert, Simon A1 - Ramirez-Ruiz, Sebastian T1 - Meta-Analysis of the Effects of Voting Advice Applications JF - Political Communication N2 - We review the influence of voting advice applications (VAAs) on three core outcomes: turnout, vote choice, and issue knowledge. In a meta-analysis of 55 effects reported in 22 studies, comprising 73,673 participants in 9 countries, we find strong evidence for positive effects of VAA usage on reported turnout (OR = 1.87; 95% CI = [1.50, 2.33]) and vote choice (OR = 1.44; 95% CI = [1.16, 1.78]) as well as modest evidence on knowledge increase (partial correlation = 0.09; 95% CI = [−0.01, 0.18]). At the same time, we observe large heterogeneity in effect sizes, for which study design turns out to be a key driver. Effects are substantively weaker in causally more rigorous experimental studies. We highlight the need for more well-powered experimental research as well as studies focusing on the acquisition of knowledge in VAA usage.
