Coercive control is the deliberate act of destroying a person’s actual or perceived agency through the use of coercive power tactics. While coercive control has increasingly been the subject of academic research in recent years, coercive control as a social phenomenon is still poorly understood. To date, the concept of coercive control in groups has been explored through theory and case study, but not through a formal computational methodology. The present study explored coercive control associated with charismatically led groups, in which the underlying dynamics between group members and group leadership are dysfunctional with regard to themselves, others, and aspects of everyday life. Through a historical case analysis of Peoples Temple and the 1978 Jonestown murder-suicide of over 900 persons, this research developed a mixed qualitative-quantitative methodology to support computational analysis of coercive control in groups with an emphasis on assessing the risk of violent behavior. The findings from this research suggested that the proposed methodology produced empirically-supported metrics of coercive control that could also potentially be integrated into more sophisticated computational techniques such as those based in machine learning principles.
