In-group solidarity or out-group hostility in response to terrorism in France? Evidence from a regression discontinuity design

Abstract

Conventional wisdom holds that terrorism has a wide-ranging impact on a polity. At the same time, a complementary, yet less extensive body of research discusses the impact of terrorism on the crux of representative democracy, namely its citizens. In contribution to that literature, and to further explore how external shocks affect public opinions, we propose a two-dimensional analytical framework to examine the effects of the November 2015 terrorist events in Paris and Saint Denis. Drawing from extant scholarship, we argue that we can expect both in-group solidarity and out-group hostility to increase in direct response to these events. This study relies on a regression discontinuity design to analyse a representative survey (DREES) that was in the field at the time of the events. Findings are two-fold. First, and perhaps surprisingly, we find no conclusive evidence of increasing out-group hostilities as a direct consequence of the terrorist events. Second, we find a definite strengthening of in-group solidarity indicators following the events. This not only confirms that citizens adjust their opinions in response to environmental stimuli, but also highlights the democratic resilience of citizens, particularly when faced with a collective threat. Altogether, these findings add to our understanding of why and how individual behaviour changes in light of exogenous shocks.
