Generational studies have been widespread in Iran in the last three decades and it can be considered as a social probelm for Iranian social sciences. On the one hand, research paradigms have special problematics and methodologies in their heart, and on the other hand, as much as they clarify some aspects of reality, they also hide some aspects and make them invisible. In this article, an attempt has been made to sum up these studies with the meta-analysis method of existing studies, focusing on their missing and hidden points, so that it can be explained what aspects of reality these studies have made invisible and what models of interpretation due to the non-scientific assumptions. have imposed on reality. As a result, the findings indicate that these studies were built in the general paradigm of traditional/modern passage and based on political concern after the movement of 1997 (2nd khordad) and tried to statically place the generations at the two ends of the traditional and modern spectrum, and usually differences, conflicts and highlight the gap between these two generation. Static perception of generations and lack of attention to their internal diversity is also part of the story. For this reason, generational studies require a fundamental review that not only has a dynamic and fluid understanding of generations, but can also consider the internal diversity of each generation. In this case, you can have a creative and dynamic image of Iranian culture.
