限制理性 Bounded rationality

限制理性（英語：Bounded rationality），又譯為有限理性，係由赫伯特·亞歷山大·西蒙（Herbert Alexander Simon）所提出，是基於生理學及心理學層面的思考，對於傳統經濟學理論所提出的修正。傳統經濟學一直以完全理性為前提，由於行為人可以得到所有資訊，因此可以在多種方案中，選擇能使效用最大化的一種方案；但是於現實狀況中，人們所獲得的資訊、知識與能力都是有限的，所能夠考慮的方案也是有限的，未必能作出使得效用最大化的決策。因此，西蒙認為必須考慮人的基本生理限制，以及由此而引起的認知限制、動機限制及其相互影響的限制。
西蒙所提出的理論是，將不完全的資訊以及處理資訊的費用，和一些非傳統的決策者目標函數引入經濟分析。

Bounded rationality is the idea that when individuals make decisions, their rationality is limited by the tractability of the decision problem, the cognitive limitations of their minds, and the time available to make the decision. Decision-makers in this view act as satisficers, seeking a satisfactory solution rather than an optimal one. Herbert A. Simon proposed bounded rationality as an alternative basis for the mathematical modeling of decision-making, as used in economics, political science and related disciplines. It complements "rationality as optimization", which views decision-making as a fully rational process of finding an optimal choice given the information available. Simon used the analogy of a pair of scissors, where one blade represents "cognitive limitations" of actual humans and the other the "structures of the environment", illustrating how minds compensate for limited resources by exploiting known structural regularity in the environment.

有時，時間和能力所限，採用bounded rationality都不錯，起碼提高了得到的結果水平。
