"Dispute" is the most basic forms of human communication that occurs under various circumstances. The main issue addressed in this paper is quality of disputes and their solutions that are mediated by generations. After reviewing the conceptual aspects, various theories have been proposed. Question model based on theoretical rudiments were designed. The main method to collect field data is in-depth interviews by various people living in Tehran that belongs to younger age (15 to 29 years), middle-aged (30 to 49 years) and elderly generations (50 years old and up) in two groups: men and women. More than forty-five interviews in this area have been collected and analyzed. Based on the information obtained, generational experiences have main role in formation of subjectivity, modes of dispute-confrontation and their strategies of solutions in various social positions. Younger generations because of their socialization and norms that gradually learning choose more faster and ejective strategies. While later generations with diverse experiences gained over the time lead to solving disputes by neglect, passivity or reform. Thus generation is a major mediator in Iranian social relations especially in dispute-confrontations.
