The present study aims to discuss a macro-narrative in the analysis of development obstacles in Iran. Political culture approach is a structural psychological approach that stresses the decisive role of culture in development and reduces the development obstacles to cultural matters. Its main suggestion is transition from tradition to modernity and its data includes psychological elements, stories and accounts. This approach was adopted by some voyagers (diarists) and diplomats to understand the third world and later some political scientists used this data to form their theories. The important question posed by this study is that why this approach adopted to study Iran and what are its implications and inefficiencies to understand the obstacles of development in this country? The findings of the study show that Macro-Narratives including political culture approach due to reductionism, essentialism, general orientation, lack of attention to the complexities of the societies and other factors are inefficient for analyzing Iran’s developments. Therefore, to understand Iran, one has to bypass the macro-narratives and applies the micro ones. The research method is explanatory by using documentary studies and critique and reviewing the published works within the framework of this approach.
