What is the role of culture in establishing young people’s pathways into gang membership? Italian criminal organizations (COs) exhibit adherence to codes of honor and masculinity, important values in the context where they originated. Here it is proposed that the embedding of these values at an individual level may lessen young people’s group-based opposition to such organizations, and indirectly, create a space in which such organizations can persist and recruit. In a study of young Southern Italians (N = 176; M_age = 16.17), we found that those who endorsed ideological beliefs related to the honorableness of male violence reported lower intentions to engage in antimafia activities. Consistent with the hypothesized mechanisms, this relationship was mediated by more positive attitudes toward COs, and lower reported vicarious shame in relation to the activities of COs. Directions for future research and implications for research on gangs are discussed.
