International Relations refers to 3 Levels of Analysis to explain the factors, or concepts, responsible for events that occur:


Systemic Level

Consists of factors that are outside of a state's control (External factors)

Some Examples:
  • Anarchy
  • States (Great Powers)
  • Geography
  • Balance of Power (Relative Power)
  • Technology 

Realism often uses systemic level factors to explain realist theories.

Domestic Level

Consists of factors that are within a state's control (Internal factors)

Some Examples:
  • Regime Type 
  • Strong/Weak Society (How society interacts with the state)
  • Institutions 
  • Economic Policies
  • Culture
  • Public Opinion 

Liberalism often uses domestic level factors to explain liberalist theories. 

Individual Decision-Maker Level

Consists of factors that deal with the state's leader/ decision-maker 

Some Examples:
  • Personality
  • Attitudes and Belief Systems (Where do these come from?)
  • Psychological Aspects (Cognitive Factors) 

The problem with this level is that it is not generalizable (everyone is different).
