Replication Data for: How Terrorism Does (and Does Not) Affect Citizens’ Political Attitudes: A Meta-Analysis

How does terrorism affect citizens’ political attitudes? Over the years, many scholars have tried to answer this question. This article performs a meta-analysis on this literature, reviewing about 325 studies conducted between 1985 and 2020 on more than 400,000 respondents. The findings confirm that terrorism is associated—to a small but significant extent—with out-group hostility, political conservatism, and rally-‘round-the-flag effects. At the same time, the effects of terrorism vary widely, with studies on Islamist violence, conducted in the United States or Israel, and using cross-sectional data yielding stronger results on average. Finally, the review reveals remaining gaps in this field of study, including a lack of research on non-Islamist violence or conducted in non-Western contexts. Taken together, this meta-analysis consolidates existing evidence, determines which results hold across contexts, and identifies key gaps in our current knowledge. Its data can also be accessed interactively via a Shiny App.
