The function of political psychology in the world of diplomacy

Today, there is a deep belief that man, as a political animal, is motivated by emotions and internal functions of the brain and makes decisions within the framework of these emotions. From this point of view, psychology can be more effective than any other field in international relations as a window to understand politics. In the meantime, diplomacy, as the knowledge of the communication between representatives of countries and the beating heart of international politics in order to resolve disputes, needs to be equipped with psychology more than any other aspect of this field. In this regard, this article, with the aim of exploring the role and function of political psychology in diplomacy, seeks to answer the question; How and why can political psychology help diplomats in the process of diplomacy? Using the descriptive-analytical method and based on documentary studies, this hypothesis was tested that the actions of all people in the world are directed by their perceptual-personal treasury and mental expectations. Therefore, the mind as an active mirror shapes the phenomena and concepts, and the diplomat, by mastering psychology and personality cult, can reflect what he wants in this mirror to a large extent.
