What political, economic, religious, and emotional factors are involved in a person's decision to kill civilians and military personnel through the sacrifice of his or her own life? Data for this research were secondary analyses of interviews with Islamic martyrs, as well as their leaders’ speeches. This investigation into the cultural-psychological explanations for Islamic martyrdom leads to a model explaining a person's decision to carry out the mission as resulting from a combination of four factors: the historical-cultural context, group processes, (...) immediate and anticipated rewards, and mechanisms to eradicate possible doubts and guilt regarding this decision. Compared to existing models, this model is more integrative and focused on the psychological processes involved. (shrink)
