「初心者でも分かる!システム設計視点の 行動経済学」は、人間の限界合理性や認知バイアスを単なる『心のクセ』で終わらせず、社会システムにおけるUI/UX(インターフェース)の仕様や脆弱性として捉え、「人を責めるのではなく、仕組みをデバッグ・リファクタリングする」という工学的な思考法で社会制度を解き明かす 教育コンテンツ・連載シリーズです。ナビゲーターである「DJミオ」と「DJレン」のラジオ番組風の対話形式で親しみやすく進行されます。


主な特徴とアプローチ

  1. 認知バイアスを社会システムの「仕様・脆弱性」として捉える
    • フレーミング効果や損失回避、アンカリング、報酬ハッキング(グッドハートの法則)といった行動経済学・AI安全性の概念を、人間の欠陥ではなく社会システムにおけるインターフェースの仕様や脆弱性として定義します。
  2. 制度課題をシステムエンジニアリング用語へ翻訳・再構築
    • 善意や「察し」に依存しないゼロトラスト設計、データによる可観測性・監査可能性の確保、バグの早期検知と低コストな更新を実現する民主主義のCI/CDなど、エンジニアになじみ深い概念で制度設計論を再構築します。
  3. 社会・国家を「自己修復可能な国家OS」として捉える視点
    • 帳簿上の数字に惑わされる「財源幻想」を解体し、真の制約である**「供給能力(リアルリソース)」を防衛・拡張します。103万円・130万円の壁といった「段差関数バグ(崖効果)」を解消し、「普通の人が普通に行動しても破綻しないインセンティブ設計」**を目指します。

シリーズの全体像(全50回の展開)

本シリーズは、個人の認知分析から始まり、国家OSのリファクタリング、社会構造の接続設計、そして起動アクションへと段階的に進みます。

  • Arc I:認知バイアスとシステム設計の基礎(第1回〜第4回)
    • フレーミング、報酬ハッキングとグッドハートの法則、防衛者のジレンマ、供給能力の防衛と財源幻想の解体を学びます。
  • Arc II:国家OSのリファクタリング(第5回〜第15回)
    • 低賃金依存構造、移行コスト、ゼロトラスト設計、可観測性・監査可能性、「年収の壁」の段差関数バグ、税や社会保障を「行動関数を制御するパラメータ」として再定義します。
  • Arc III:人間的な社会ルールの設計(第16回〜第20回)
    • 子育て支援・少子化対策を「人的資本投資」として再設計し、外国人材受け入れ政策における接続条件と世代を超えた遅延コスト(2世・3世問題)を議論します。
  • Arc IV:制度改革の担い手設計(第21回〜第30回)
    • 「誰が悪いか」から「どう直すか」への責任帰属バイアスの転換、官僚機構の「学習する組織」化、企業インセンティブの再設計と民主主義CI/CDを構築します。
  • Arc V:経済認知のバグ解剖(第31回〜第40回)
    • 「説得」ではなく「問いを増やす」5ステップ対話、沈黙の螺旋の解消、三権分立のMTTD/MTTR再定義、市民によるコードレビューの実践を提示します。
  • Arc VI:処方箋の実装と起動(第41回〜第50回)
    • 医療・労働(フレキシキュリティ)・格差(EITC)・地方財政・通商外交・AI活用の領域別リファクタリング、Layer 0〜3ロードマップ、そして社会を変える「25%の臨界点(起動コマンド)」へと結びつけます。

姉妹連載「Pythonで学ぶマクロ経済学入門」との二輪関係

本シリーズは、データと定量シミュレーションを扱う姉妹連載『Pythonで学ぶマクロ経済学入門』(全100回)と強力な補完関係にあります。

  • 『行動経済学シリーズ』(Why / How)=【デバッガー】
    • 「人はどう誤るか」「なぜ制度はバグるのか」という人間・制度内部の行動特性やインセンティブの歪みを解明・設計します。
  • 『マクロ経済学入門シリーズ』(What / How much)=【シミュレーター】
    • 「そのバグや制度変更が、マクロ経済(GDP・物価・雇用・供給能力)にどのような規模で影響を与えるか」をPythonコードと実データで定量検証します。

2つのシリーズを掛け合わせることで、**「認知 → インセンティブ → 制度 → マクロ結果」**という動学的な国家OSのデバッグ・検証ループを回すことができます。
