political conditions of instability

most theories in social sciences have aspects of causality, but understanding the causes of social phenomena is not possible through statistical correlation tests. to overcome this problem, fuzzy qualitative comparative analysis was developed to identify the cause of social phenomena. having qualitative roots, this method tests the necessary and sufficient causes for the emergence of a social phenomenon. the present article seeks to identify the political causes of instability. to achieve this goal, a wide range of political variables affecting political instability were first derived from the theories of social sciences. then these variables were tested experimentally by comparing 183 countries in the world. the results indicated that the following four variables out of 18 political ones are the causes of political instability: lack of rule of law, government corruption, lack of elite consensus and undemocratic political culture.
