A contentious issue regarding immigration is the contempt that many natives hold for immigrants. Studies report that enhanced job competition, the potential for cultural misunderstandings, and security fears are salient in predicting native population discontent for immigrants. However, the threat posed by terrorism has been overlooked in prior research. Using data drawn from twenty mostly European countries and a nonlinear hierarchical modeling statistical procedure, we find that acts of terrorism are associated with a substantive decrease in the desire for outgroup immigration. No effect of terrorism on ingroup immigration is observed. The theoretical implications of these findings are discussed.
