Question

Quizplus · Accepted Answer

Both the realist and liberal perspectives generally use rationalist methods. Realists prioritize national interests and security, and seek to understand the world through the balance of power and strategic calculations. Liberals prioritize cooperation and interdependence, and seek to understand the world through rationalist institutions and economic principles. Both rely heavily on rational analysis and logical deduction. The identity perspective, on the other hand, prioritizes the role of cultural, historical, and psychological factors in shaping international relations, and is more associated with constructivist methods.
