Now, visualize that you are one of a few privileged that have the possibility of interviewing people who have been involved in some of the most dramatic terrorist attacks in history. What should you do? Most investigations focused on terrorism do not include empirical data and just a handful of fortunate have made face-to-face interviews with these individuals. Therefore, we might conclude that most experts in the field have not directly met the challenge of experiencing studying violent radicalization in person. As members of a research team who have talked with individuals under risk of radicalization, current, and former terrorists, our main goal with this manuscript is to synopsize a series of ten potential barriers that those interested in the subject might find when making fieldwork, and alternatives to solve th...

In five studies (total n > 1,700), we investigated whether costly behaviours are more effective in promoting trust when integrated within a religious rather than secular context using the pilgrimage to Santiago de Compostela as a costly display of commitment. First, we show that pilgrims base their pilgrim identity on physical effort (Studies 1A and 1B). Next, in three pre‐registered experiments (Studies 2–4) with the Spanish population, we compared the trustworthiness of people posting on Facebook about their participation in a religious pilgrimage and a secular pilgrimage/hike with various control posts. The results showed that pilgrims/hikers are perceived as more trustworthy than non‐pilgrims and that long‐distance pilgrims are perceived as more trustworthy than short‐distance pilgrims. Moreover, these effects are stronger when the pilgrimage is framed in a religious context compared to a sec...

We investigate two key components of this process: (1) the feeling of admiration toward ingroup members making costly self-sacrifices for their ideological group, and (2) identity fusion with religion. Data collected in 27 Spanish prisons reveal that jihadists’ admiration toward members of radical Islamist groups amplifies their willingness to engage in costly sacrifices for religion in prison. This effect is produced because admiration toward radical Islamist groups has a binding effect, increasing identity fusion with religion. Five additional experiments provide causal and behavioural evidence for this model. By showing that admiration for ingroup members increases identity fusion, which in turn makes individuals prone to engage in costly pro-group behaviours, we provide insights into the emotional machineries of radicali...

We offer an initial answer using face-to-face interviews and structured surveys in thirty-five Spanish prisons. Recent theories of extreme sacrifice inform this direct observational and comparative study. Islamist terrorists display levels of self-sacrifice for their primary reference group similar to that of Latino gangs, but greater willingness to sacrifice for primary values than other inmates (non-radical Muslims, Latino gangs, and delinquent bands). This disposition is motivated by stronger perceived injustice, discrimination, and a visceral commitment to such values (risk/radicalization factors). Nevertheless, state authorities, prison staff, and families are (protective/de-radicalization) factors apt to reduce willingness to sacrifice and keep foreign fighters, now being released in large numbers, from returning to terrorism.

Here, we investigate whether these tendencies are partly attributable to distrust in scientific information, and evaluate whether they generalize outside the U.S., using public data and recruited representative samples across three studies (Ntotal = 34,710). In Studies 1 and 2, we examine these relationships in the U.S., yielding converging evidence for a sequential indirect effect of conservatism on compliance through scientific (dis)trust and infection concern. In Study 3, we compare these relationships across 19 distinct countries. Although the relationships between trust in scientific information about the coronavirus, concern about coronavirus infection, and compliance are consistent cross-nationally, the relationships between conservatism and trust in scientific information are not. These relationships are strongest in North Am...

We propose that strongly fused individuals are characterized by feelings of visceral responsibility towards such target - unconditional, instinctive, and impulsive drive to care, protect and promote its well-being and interests - that motivates them to self-sacrifice. Two studies offered initial support when the target of fusion is an individual or a group (Studies 1a-1b). A final study added causal evidence that strongly fused learning that most ingroup members did not feel visceral responsibility towards the group expressed less willingness to self-sacrifice than those learning that ingroup members display high levels of visceral responsibility (Study 2). These findings offer novel evidence for the mechanisms underlying the effects of fusion on extreme behaviour on behalf of the target of fusion and the attenuation of its consequences.

However, the effects of fusion depending on the nature of such behaviors -violent versus non-violent- and the factors that may incline strongly fused individuals to display them still remain unexplored. To fill this gap, we performed two correlational studies in which we examined whether moral beliefs regarding the justifiability of violence moderate the relationship between fusion with the family (Study 1), or with the country (Study 2), and willingness to engage in violent and non-violent pro-group acts. Results showed that strongly fused participants were more willing to act violently than weakly fused participants, but only when their beliefs in the moral justifiability of violence were high. In contrast, their willingness to engage in non-violent acts was not influenced by moral beliefs.

In Study 4, we compare these relationships across 19 distinct countries, finding that they are strongest in North America, extend to support for lockdown restrictions, and that the indirect effects do not fully appear in any other country in our sample other than Indonesia. These effects suggest that rather than a general distrust in science, whether or not conservatism predicts co...

Compliance occurs when individuals are coerced to join by powerful influence agents. Internalization occurs when individuals join due to a perceived convergence between the self and the group. We searched for evidence of each of these pathways in field investigations of former members of two renowned terrorist organizations: the Liberation Tigers of Tamil Eelam (LTTE) (Study 1) and Islamist radical groups (Study 2). Results indicated that ex-fighters joined LTTE for reasons associated with both compliance and internalization but that ex-fighters joined Islamist radical groups primarily for reasons associated with internalization. When compliance occurred, it often took the form of coercion within LTTE but involved charismatic persuasion agents within Islamist groups. This evidence of systematic differences in the reasons why fighters enter violent groups suggests that strateg...
