In which theoretical approach do actors succeed based on rational decision-making processes?

The chosen answer, Rationalism, is accurate because it is a theoretical framework in international relations that emphasizes the role of rational decision-making by actors, which often includes states, organizations, or individuals. Rationalism posits that these actors make choices based on the assessment of their preferences and the available options to achieve their goals. This approach is rooted in the idea that actors are logical and will select policies that maximize their utilities, considering the consequences of their decisions and the actions of others.

Rationalism encompasses various models, including game theory, which focus on strategic interactions and highlight how rational players calculate their best moves based on expected responses from other actors. This approach contrasts with other theories that may not prioritize or may even reject the concept of rational decision-making.

In contrast, approaches like Postmodernism tend to question the existence of objective truths or rationality itself, focusing instead on the social construction of meaning and differences in perspective. Realism, while it acknowledges power-oriented behaviors and interests, does not strictly adhere to the rational decision-making model and often emphasizes the anarchic nature of international relations as a fundamental driver of state behavior. Behaviorism, on the other hand, focuses on observable behaviors often using empirical methods, which may not necessarily involve rational choice as
