なんなら、自身の選好すら よく知らない。

手続的合理性
デフレ版(ショボい版)の認識を表した概念
antithesis: 経済人、神の見えざる手
伝統的な経済学だろうと、無限の能力は仮定してないと言うが…?
Traditional economics assumes that economic agents are **rational** and make decisions based on **self-interest** and **new information** ¹. However, it does not assume that economic agents have **unlimited computing and communication abilities**. In fact, traditional economic theory relies on relatively simple models of human behavior that do not take into account the full range of cognitive limitations and biases that affect decision-making in the real world ¹.
If you would like to learn more about the differences between traditional and behavioral economics, you can check out this article from The Chicago School ¹. It provides a detailed comparison of the two fields and explains how behavioral economics enriches traditional economics by incorporating insights from psychology, sociology, politics, and other disciplines.
I hope this helps!

『ミクロ経済学の力』
経済学というのは計算可能性を問題にしている
経済学とはそもそも計算モデルを開発する事なのだ
計算モデル
