The process of political decision-making occupies a prominent and significant position in the field of political studies in general, as it represents the essence of the political process on the one hand, and because political decisions have a profound impact on individuals and societies on the other hand. Therefore, since ancient times, humans have recognized the importance of decision-making and the factors that contribute to its formulation. Plato (in the fourth century BC) used the term “decision” when he stated that rulers, and no one else, were the center of decision-making in Athens, while the role of others was to implement what the rulers had decided. The Greek historian Thucydides (in the third century BC) also wrote about the Peloponnesian War and the factors that influenced the leaders of Greek cities in making decisions regarding war, peace, or alliances. In this context, Thucydides discussed environmental and strategic factors, in addition to subjective factors such as psychological conditions and self-interest, which compelled political leaders to make certain decisions during that period.
