Around the world, violence is considered a substantial social, political, religious, and health issue. To understand violence in a society, it is essential to consider the processes that validate such behaviors. Validation is based on the rationalization process utilized by people and the mechanisms that support it. This study focuses on two such mechanisms: religion and patriarchal traditionalism. Religion is often blamed for inciting violence worldwide and is also confused for supporting social and cultural traditions in constructing perceptions that justify violence. Some religions also support patriarchal traditions, where men are taught to have power and women are told to act as subordinates. This research examines the effects of religiosity, patriarchal traditionalism, and their interactions on the justification of physical violence. This study uses Wave 6 (2010-2014) World Value Survey (WVS) data from the United States. The main hypotheses of the research are that religiosity lowers the probability of individuals' justification of physical violence, and patriarchal traditionalism has a positive relationship with the justification of physical violence. Ordered logistic regression is used to test the hypotheses. This research fills in the literature gap by looking at the effects of religious belief, religious practice, patriarchal traditionalism, and the interaction of the two on the justification of physical violence. Results reveal that religiosity does have a negative impact on the justification of physical violence, and patriarchal traditionalism does have a positive role in justifying physical violence. The interactions show that the effects of religious belief and religious practice on justifying violence are more substantial for those who score higher on the patriarchal traditionalism scale. Therefore, it can be concluded that patriarchal traditionalism moderates the relationship between religiosity and views justifying physical violence.
