Behaviorist approaches differ from the traditional approaches in the sense that they focus on processes and motives of foreign policy-making. Behavioural approaches have developed as part of the methodological critiques of rational choice theory. According to this, rationality is not absolute and is constrained by other dynamics that should be included in the analysis of foreign policy. Traditional approaches use rational-choice theory as a methodology, focus on a unified decision-making body in the form of the state, have inquiries about foreign policy, and base their explanation on systemic factors.
