How Moral Beliefs Influence Collective Violence. Evidence From Lynching in Mexico
Nussio, Enzo (2025)
Comparative Political Studies
How do moral beliefs influence favorability to collective violence? In this article, I argue that, first, moral beliefs are influential depending on their salience, as harm avoidance is a common moral concern. The more accessible moral beliefs in decision-making, the more they restrain harmful behavior. Second, moral beliefs are influential depending on their content. Group-oriented moral beliefs can overturn the harm avoidance principle and motivate individuals to favor collective violence. Analysis is based on a representative survey in Mexico City and focuses on a proximate form of collective violence, locally called lynching. Findings support both logics of moral influence. Experimentally induced moral salience reduces favorability to lynching, and group-oriented moral beliefs are related to more favorability. Against existing theories that downplay the relevance of morality and present it as cheap talk, these findings demonstrate how moral beliefs can both restrain and motivate collective violence.
Views on Islam in Times of Terrorism
Farman, Darius; Nussio, Enzo (2018)
CSS Analyses in Security Policy
Islamophobia is not more prevalent in Switzerland today than it was before the terrorist violence that Europe has experienced since the 2015 attacks in Paris. Still, Muslims today are often victims of discrimination. The polarized public discourse about Islam may have helped to erode psychological inhibitions against discriminatory behavior.
The “Dark Side” of Community Ties: Collective Action and Lynching in Mexico
Nussio, Enzo (2024)
American Sociological Review
Lynching remains a common form of collective punishment for alleged wrongdoers in Latin America, Africa, and Asia today. Unlike other kinds of collective violence, lynching is usually not carried out by standing organizations. How do lynch mobs overcome the high barriers to violent collective action? I argue that they draw on local community ties to compensate for a lack of centralized organization. Lynch mobs benefit from solidarity and peer pressure, which facilitate collective action. The study focuses on Mexico, where lynching is prevalent and often amounts to the collective beating of thieves. Based on original survey data from Mexico City and a novel lynching event dataset covering the whole of Mexico, I find that individuals with more ties in their communities participate more often in lynching, and municipalities with more highly integrated communities have higher lynching rates. As community ties and lynching may be endogenously related, I also examine the posited mechanisms and the causal direction. Findings reveal that municipalities exposed to a recent major earthquake—an event that tends to increase community ties—subsequently experienced increased levels of lynching. Importantly, I find that interpersonal trust is unrelated to lynching, thus showing that different aspects of social capital have diverging consequences for collective violence, with community ties revealing a “dark side.”
How to Keep the FARC Guerrillas Out of the Fight
Kaplan, Oliver; Nussio, Enzo (2017)
The New York Times
After years of tumultuous peace talks, the Revolutionary Armed Forces of Colombia, better known as FARC, bid a final farewell to arms in June. The act heralds the end of a 52-year conflict. But for Colombia to decisively break with its past, it must be smart in its approach to reintegrating FARC combatants back into society.
¿Por qué los rebeldes dejan de luchar? Declive organizacional y deserción en la insurgencia de Colombia
Nussio, Enzo; Ugarriza, Juan E. (2022)
Colombia Internacional
Objetivo/contexto: la deserción, o salida no autorizada de un grupo armado, tiene importantes implicaciones para la contrainsurgencia, la terminación de una guerra y la dinámica de reclutamiento. Si bien la investigación existente enfatiza la importancia de motivaciones individuales para la deserción, el declive organizacional, en forma de adversidad militar y financiera, también puede condicionar la deserción. El declive organizacional socava los instrumentos de un grupo para canalizar las preferencias individuales hacia la acción colectiva. Estos instrumentos incluyen los incentivos selectivos, el atractivo ideológico y la coerción. Cuando el poder vinculante de estos instrumentos disminuye, los deseos individuales comienzan a dominar el comportamiento, lo que aumenta la probabilidad de deserción. Metodología: se utiliza la insurgencia de las Fuerzas Armadas Revolucionarias de Colombia (FARC) para examinar este argumento con un enfoque multimétodo. Primero, se realiza un análisis cuantitativo para explorar datos únicos sobre más de 19.000 desertores de las FARC reportados entre 2002 y 2017, proporcionados por el Ministerio de Defensa de Colombia. Al protegerse contra amenazas a la inferencia causal, el análisis estadístico indica que el declive organizacional impulsa la deserción. En segundo lugar, se lleva a cabo un análisis cualitativo utilizando una gran cantidad de informes detallados sobre entrevistas con desertores realizadas por personal militar colombiano. Conclusiones: los informes demuestran que el declive organizacional debilita los incentivos selectivos, la ideología del grupo y un régimen coercitivo creíble, y fomenta la deserción mediante estos mecanismos. Originalidad: estos hallazgos brindan información clave para los formuladores de políticas, dado que la deserción puede contribuir tanto a poner fin a un conflicto como a acelerar el reclutamiento de nuevos combatientes.
Can Terrorism Abroad Influence Migration Attitudes at Home?
Böhmelt, Tobias; Bove, Vincenzo; Nussio, Enzo (2020)
American Journal of Political Science
This article demonstrates that public opinion on migration “at home” is systematically driven by terrorism in other countries. Although there is little substantive evidence linking refugees or migrants to most recent terror attacks in Europe, news about terrorist attacks can trigger more negative views of immigrants. However, the spatial dynamics of this process are neglected in existing research. We argue that feelings of imminent danger and a more salient perception of migration threats do not stop at national borders. The empirical results based on spatial econometrics and data on all terrorist attacks in Europe for the post‐9/11 period support these claims. The effect of terrorism on migration concern is strongly present within a country but also diffuses across states in Europe. This finding improves our understanding of public opinion on migration, as well as the spillover effects of terrorism, and it highlights crucial lessons for scholars interested in the security implications of population movements.
Why Rebels Stop Fighting: Organizational Decline and Desertion in Colombia's Insurgency
Nussio, Enzo; Ugarriza, Juan E. (2021)
International Security
The unauthorized exit from an armed organization, what we call “desertion,” is a highly consequential act. If caught, deserters may face drastic punishment, including execution. Why, then, do some members of armed groups nevertheless decide to stop fighting? In this article of the journal International Security, CSS' Enzo Nussio and Juan E. Ugarriza offer a new theoretical argument about the organizational dynamics associated with desertion, drawn from collective action theory.
Vertrauen in die Regierung zu Krisenzeiten
Nussio, Enzo (2024)
CSS Analysen zur Sicherheitspolitik
Internationale Krisen sind für Regierungen ein Stresstest. Entweder gelingt es, bei der Bevölkerung zu punkten, oder man verspielt die Wählergunst durch unpopuläre Entscheidungen. In jüngster Zeit schwankte das Vertrauen in die Regierungen in vielen europäischen Ländern stark. Die Schweizer Landesregierung hingegen profitierte von einem Vertrauensreservoir, das sie vor Unzufriedenheit schützte.
