Abstract:

Bounded rationality is not the optimization under constraints, not to mention the irrationality. In essence, it is an objective description of the level of human rational evolution and development so far, that is, human beings are rational either in the attitude to reality or in the ability to recognize and transform reality. However, limits to human rationality are observed. Bounded rationalists question popular rationalism in contemporary social science and the reliability of the methodology and knowledge system derived from it, but they do not question rationality itself. They eliminate the dualism thinking mode of rationalism or irrationalism in history, which provides us with a new perspective to understand the nature of rationality from the resource-based, quantitative, and dynamic developmental views. Bounded rationality is defective in the sense of value rationality, but reasonable in the sense of instrumental rationality. Therefore, it is necessary to find a proper equilibrium point between them. The concept of bounded rationality in psychology and its extensive influence have led to another human rational revolution after the “probability revolution” of the Renaissance. It is one of the most important contributions made by this discipline to the treasure house of human thought and knowledge. It not only has far-reaching historical significance but also has interdisciplinary methodological significance.
