Decision Field Theory (DFT) is a dynamic cognitive model that mathematically explains the process through which humans choose among options while wavering over time. Unlike traditional economic theories, it can predict not only the “outcome” of a decision but also the “time taken to choose (reaction time)” and “changes of mind.” Core idea: People repeatedly alternate between considering the advantages and disadvantages of each option, gradually accumulating evaluations (sampling). Fluctuation in preference: Over time, the inclination (preference) toward a particular option in the mind rises and falls like a wave. Crossing a threshold (Japanese reading: shikiichi): A choice is made the moment its accumulated preference first reaches a “boundary (threshold)” set beforehand within oneself.

意思決定場理論(Decision Field Theory: DFT)は、人間が時間をかけて迷いながら選択肢を選ぶプロセスを数学的に説明した動的な認知モデルです。従来の経済学理論とは異なり、意思決定の「結果」だけでなく、「選ぶまでの時間(反応時間)」や「心の移り変わり」も予測できます。 核心となる考え方人間は頭の中で、各選択肢のメリットとデメリットを何度も交互に思い浮かべ、評価を少しずつ蓄積(サンプリング)していきます。選好度(Preference)の変動: 時間の経過とともに、頭の中で特定の肢への傾き(選好度)が波のように上下します。閾値(しきいち)の突破: 蓄積された選好度が、あらかじめ自分の中で設定した「境界線(閾値)」に最初に達した瞬間に、その選択肢に決定します。
