Scholars have urged a shift in research on mass murder from the creation of typologies to theoretically rich, data-driven comparative examinations of the phenomenon. We seek to redress such calls in two ways. First, we analyze a unique sample of public mass murderers through the multistage explanatory model of cumulative strain theory. Second, we use a comparison group of similarly violent offenders—lone actor terrorists—to provide context to our findings. The results demonstrate that cumulative strain theory usefully describes the trajectory toward violence of public mass murderers, more so when a concept implicit in the theory—grievance—is made explicit.

共同奋斗？1990年至2014年的累积应变理论与大众杀人犯

学者们敦促大规模谋杀的研究从类型学的创建转向理论上丰富的，数据驱动的对该现象的比较研究。我们试图以两种方式纠正这种呼吁。首先，我们通过累积应变理论的多阶段解释模型来分析公共杀人犯的独特样本。其次，我们使用了一组类似暴力罪犯的比较组-单独演员恐怖分子-为我们的调查结果提供背景信息。结果表明，累积应变理论有用地描述了公共大屠杀者暴力行为的轨迹，当理论中隐含的一个概念即“不满”变得更加明确时，更是如此。
