What are disadvantages of rational decision making model?

The rational decision-making model can be limited by its assumption of complete information, which is often unrealistic in real-world situations. It may also overlook the emotional and psychological factors that influence human behavior, leading to decisions that are not purely logical. Additionally, the model can be time-consuming and resource-intensive, as it requires thorough analysis and evaluation of all possible alternatives. Lastly, it may not adequately address the complexities and uncertainties inherent in many decision-making contexts.
