CORRELATES OF VIOLENT POLITICAL EXTREMISM IN THE UNITED STATES*

Although research on terrorism has grown rapidly in recent years, few scholars have applied criminological theories to the analysis of individual‐level political extremism. Instead, researchers focused on radicalization have drawn primarily from political science and psychology and have overwhelmingly concentrated on violent extremists, leaving little variation in the dependent variable. With the use of a newly available data set, we test whether variables derived from prominent criminological theories are helpful in distinguishing between nonviolent and violent extremists. The results show that variables related to social control (lack of stable employment), social learning (radical peers), psychological perspectives (history of mental illness), and criminal record all have significant effects on participation in violent political extremism and are robust across multiple techniques for imputing missing data. At the same time, other common indicators of social control (e.g., education and marital status) and social learning perspectives (e.g., radical family members) were not significant in the multivariate models. We argue that terrorism research would benefit from including criminology insights and by considering political radicalization as a dynamic, evolving process, much as life‐course criminology treats more common forms of crime.     

SELF‐CONTROL THROUGH EMERGING ADULTHOOD: INSTABILITY,MULTIDIMENSIONALITY, AND CRIMINOLOGICAL SIGNIFICANCE

This study assesses self‐control theory's stability postulate. We advance research on self‐control stability in three ways. First, we extend the study of stability beyond high school, estimating GBTMs of self‐control from ages 10 to 25. Second, drawing on advances in developmental psychology and social neuroscience, especially the dual systems model of risk taking, we investigate whether two distinct personality traits—impulsivity and sensation seeking—often conflated in measures of self‐control, exhibit divergent developmental patterns. Finding that they do, we estimate multitrajectory models to identify latent classes of co‐occurring developmental patterns. We supplement GBTM stability analyses with hierarchical linear models and reliable variance estimates. Lastly, using fixed effects models, we explore whether the observed within‐individual changes are associated with changes in crime net of overall age trends. These ideas are tested using five waves of data from the Family and Community Health Study. Results suggest that self‐control is unstable, that distinct patterns of development exist for impulsivity and sensation seeking, and that these changes are uniquely consequential for crime. We conclude by comparing our findings with extant research and discussing the implications for self‐control theory.
