Cross-cultural fraud is a research concept investigating intentional deceptive practices that exploit or manipulate cultural differences, norms, or communication styles for illicit gain or advantage. It examines the nature, mechanisms, and impacts of fraudulent activities occurring across or between distinct cultural groups, focusing on the deliberate exploitation of cultural knowledge gaps, biases, or communication barriers. The significance of this field lies in understanding how cultural factors intersect with and enable deceptive behaviors in a globalized context, informing strategies for detection, prevention, and redress.
