The Bureaucratic Politics of Cyber Strategy
Why do states implement certain cyber strategies, and why might they change over time? We argue that an important but overlooked factor is bureaucratic politics. Specifically, intelligence and military agencies each prefer different cyber strategies owing to their unique organizational cultures. As bureaucracies commonly do, they compete to influence strategies in their favor. When intelligence agencies prevail, we expect more risk-averse cyber s…

Divided Not Conquered: How Rebels Fracture and Splinters Behave
Less academic: Terrorist, rebel, and insurgent groups face myriad challenges. Between state repression and fears of infiltration and defeat, it is no surprise they are prone to infighting, instability, and division. And these divisions are meaningful: one led the Islamic State to break from Al Qaeda, and others have perpetually plagued the Irish Republican Army, Palestinian militants, and many more. This book analyzes how armed groups fracture an…
Honor Among Thieves: Understanding Rhetorical and Material Cooperation Among Violent Nonstate Actors
Cooperation among militant organizations contributes to capability but also presents security risks. This is particularly the case when organizations face substantial repression from the state. As a consequence, for cooperation to emerge and persist when it is most valuable, militant groups must have means of committing to cooperation even when the incentives to defect are high. We posit that shared ideology plays this role by providing community…
Internal Politics and the Fragmentation of Armed Groups
Armed groups are prone to instability and fragmentation, but what explains variation among the new groups that emerge? I argue that the internal politics preceding organizational splits is critical. When it comes to the survival of breakaway groups, those forming around single issue areas gain an advantage by attracting more homogeneous, preference-aligned recruits. On the other hand, those forming over a variety of grievances attract a more hete…
Rethinking Secrecy in Cyberspace: The Politics of Voluntary Attribution
Cyberspace affords actors unprecedented opportunities to carry out operations under a cloak of anonymity. Why do perpetrators sometimes forgo these opportunities and willingly claim credit for attacks? To date, the literature has done little to explain this variation. This article explores the motivations behind voluntary credit-claiming for the two main actors in cyberspace: states and politically motivated nonstate actors. We argue that states …
Tactical Diversity in Militant Violence
Militant groups, like all organizations, carefully consider the tactics and strategies that they employ. We assess why some militant organizations diversify into multiple tactics while others limit themselves to just one or a few. This is an important puzzle because militant organizations that employ multiple approaches to violence are more likely to stretch state defenses, achieve tactical success, and threaten state security. We theorize that m…
State Repression and Nonviolent Resistance
In this article, we review decades of research on state repression and nonviolent resistance. We argue that these two research programs have converged around six consensus findings. We also highlight several areas of divergence, where greater synthesis between the research on state repression and nonviolent resistance might prove useful. We draw attention to remaining controversies surrounding the association between state repression and nonviole…
Regression Discontinuity Design
Social scientists search for interventions in the real world that approximate the conditions of an experiment. One form of such natural experiments that is increasingly used in social science research is regression discontinuity (RD). RD designs are possible when there are thresholds that cause large changes in the assignment of treatments on the basis of small differences in a variable. For example, a high school junior in the state of Pennsylva…
