Given the pervasiveness of violent extremism all over the globe, understanding its psychological underpinnings is key in the fight against it. According to the Significance Quest Theory and its 3N model, violent extremism (i.e., violent and deviant behavior) is a function of three elements: need, narrative, and network. In the present meta-analysis, to put into test the theory and its model, we aimed to establish the strength of the association between these three elements, as well as the quest for significance itself, and violent extremism; and investigate if these associations are influenced by methodological decisions (i.e., sampling and measurements/manipulations). A literature search was performed through electronic platforms, a call for unpublished or in-press data, and backward snowballing. Seventeen reports, comprising 42 studies, met full inclusion criteria: quantitative studies based on primary data assessing for the association of at least one of the 3Ns, or quest for significance, and violent extremism, and providing sufficient data for effect size extraction. Findings are reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA) guidelines. Random-effect meta-analyses rendered statistically significant pooled effect sizes in all the investigated associations. The association is strong for quest for significance, moderate for narrative and network, and low for need for significance. Subgroup analyses demonstrate that the detection of these associations is influenced by methodological decisions concerning the measurements and manipulations, but not by those concerning the sampling. We discuss these findings and suggest future research directions aiming to improve the predictive power of the theory and its model.
According to the Significance Quest Theory (Kruglanski et al., 2009) and the 3N model (Webber & Kruglanski, 2017), violent extremism is the product of a quest for significance triggered by a need for significance (need) and nourished by subscription to a radical ideology (narrative) and affiliation with a radical network (network). The present systematic review aims to synthesize extant quantitative empirical research mobilizing this framework. We screened a total of 151 reports, of which 31 met our eligibility criteria. These regrouped a total of 84 studies. Our findings show an important heterogeneity in the measurements and manipulations of significance (need and quest), narrative, and network, as well as in the pathways examined. Moreover, while the theory’s predictions are confirmed by a majority of the studies’ findings (n = 74), such predictions are also infirmed by a considerable number of studies’ findings (n = 29). This is particularly the case for the empirical evidence related to the association between significance loss and extremism, as well as the association between significance loss and narrative, and between network and extremism. More consistent evidence was found concerning the association between significance loss and network, significance quest and narrative, significance quest and extremism, and narrative and extremism. The methodological, operational, and theoretical implications of these findings are discussed.
