One of the reasons for the ineffectiveness of the policies of the ethnic management system is information sources far from field facts.

Introduction, Review and Classification of Early Ethnic Studies in Iran 2. Checking and criticism of Ethnic studies in Iran 3. Propose a model for ethnic studies in Iran. For research purposes, descriptive-analytical method and the Technique of Review map and the form of extraction of materials have been used. One of the most important achievements of the research is designing the field of sociology of identity based on three fundamental theorems of the concepts of the media world, the real world and identity, along with the presentation of a model of diverse ethnic identity.
