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. #list
