The study centers on a major problem related to rational choice theory and its applications in international relations and foreign policy. It asks whether the selection process is subject to the principle of maximizing benefit according to this theory, or is subject to other principles, psychological processes and cognitive biases. The study reached conclusions that confirm that the selection process is in fact subject to a non-standard process; that is, it is not subject to continuous choices to benefit maximization, but there are other factors that lead to the selection of risk over gain, and here the psychological aspects overlap with the rational aspects in influencing the choice. This reveals that it is not possible to separate the school that focuses on the psychological aspects of the decision maker and the school that focuses on rational calculations, but rather that the two can be combined together within the framework of alternative theories complementary to rational choice theory, such as the perception theory.
