Psychological responses to jihadist terrorism: Exploring a small but significant opinion shift towards minority inclusion among French citizens in response to the Charlie Hebdo terrorist attacks
(2023) Lueders, Adrian; Wollast, Robin; Nugier, Armelle; Guimond, Serge
Experiences with jihadist terrorism sparked debates about the boundaries of religious expression within secular societies. Standpoints majority members hold in such discussions may be inclusive or exclusive towards religious minorities and inform wider intergroup perceptions. The present research explores these relationships in the context of the 2015 Charlie Hebdo terrorist attacks in Paris, France. Using longitudinal data from a diverse French sample (N = 558) collected before and after the attacks, we test whether within‐person changes in exclusionary and inclusionary interpretations of the French Laïcité principle can account for changes in public perceptions of context‐relevant minorities. Meta‐analytical findings suggest a small significant conservative shift after experiences with terrorism. Previous research conducted in the context of the Charlie Hebdo terrorist attacks departed from this pattern, however, without identifying underlying psychological mechanisms. Accordingly, the present data suggests a small but significant opinion shift in favor of context‐relevant minorities. This shifting was partially explained through an increased endorsement of an inclusionary interpretation of the Laïcité principle that stresses the freedom of religious expression. We offer a contextualized interpretation of our data, suggesting that the collective coping dynamics that followed the events (i.e., republican marches, #JeSuisCharlie) have been critical for the observed effects.
Response Item Network (ResIN): A network-based approach to explore attitude systems

Belief network analysis (BNA) refers to a class of methods designed to detect and outline structural organizations of complex attitude systems. BNA can be used to analyze attitude-structures of abstract concepts such as ideologies, worldviews, and norm systems that inform how people perceive and navigate the world. The present manuscript presents a formal specification of the Response-Item Network (or ResIN), a new methodological approach that advances BNA in at least two important ways. First, ResIN allows for the detection of attitude asymmetries between different groups, improving the applicability and validity of BNA in research contexts that focus on intergroup differences and/or relationships. Second, ResIN’s networks include a spatial component that is directly connected to item response theory (IRT). This allows for access to latent space information in which each attitude (i.e. each response option across items in a survey) is positioned in relation to the core dimension(s) of group structure, revealing non-linearities and allowing for a more contextual and holistic interpretation of the attitudes network. To validate the effectiveness of ResIN, we develop a mathematical model and apply ResIN to both simulated and real data. Furthermore, we compare these results to existing methods of BNA and IRT. When used to analyze partisan belief-networks in the US-American political context, ResIN was able to reliably distinguish Democrat and Republican attitudes, even in highly asymmetrical attitude systems. These results demonstrate the utility of ResIN as a powerful tool for the analysis of complex attitude systems and contribute to the advancement of BNA.
