Communication theory is one of the western schools of political science. Founded in the 1950s by Karl Deutsch, professor of political science at Harvard University. The goal is to use the principles of cybernetics to explain social and political phenomena. The core of communication theory is how the political system copes with pressure from the environment, and communication is crucial for people to control the environment. This is the main contribution of communication theory to the study of politics. Communication theory holds that the political system is always surrounded by information, and communication refers to the ability of the political system (primarily the government) to receive and respond to information, including the ability to translate, analyze, use and store information.
