This paper asserts that in Ethiopian society, there exist certain cultural norms or ‘dysfunctional behaviours’ that inhibit effective communication, lead to intra-group conflict, and make conflict resolution difficult. This has resulted in a diminished capacity for cooperation and a dearth of social capital and civil society, which does not bode well for development and democracy. It is imperative that research is expanded in the neglected area of cultural norms and social capital in Ethiopian society, and that intervention strategies are designed to increase social capital by addressing cultural norms directly through social marketing, awareness raising, and other mechanisms
