Not All Terror Is Alike: How Right-Wing Extremist and Islamist Terror Threat Affect Anti-immigration Party Support

Abstract

Abstract Terror threat has been theorized to affect political attitudes. Most prior studies have focused exclusively on Islamist terror threat, while effects of right-wing extremist terrorism on voting behavior have been understudied. We argue that effects on the propensity to vote (PTV) for an anti-immigration party (AIP) depend on the type of threat and is moderated by right-wing authoritarianism (RWA) and internal motivation to control prejudice (IMCP). Using a cross-country experiment in Germany, the Netherlands, and Sweden (N = 1,187), we find that Islamist terror threat increases PTV for AIPs amongst voters high in RWA; similarly, right-wing extremist terror threat reduces PTV for AIPs amongst participants high in RWA. IMCP did not moderate the relationship between terror threat and PTV for an AIP.
