Outline of Final Research Achievements

This project researched the behavioral and attitudinal changes under choice architecture. Study 1 investigated option-splitting effects in poll regarding Japan’s right to exercise collective self-defense. One natural experiment and one controlled experiment showed that the disparate outcomes are due to the different ways the options are segmented. Study 2 conducted a series of experiments that investigated the effects of default on decision-making over organ donation under conditions where the degree of choice freedom were experimentally manipulated. The typical default effects were obtained. Further, an experiment showed perceived choice freedom strengthened the decisional effects of default. The attitudinal effects, however, were not found. At least under this experiment paradigm, choice architecture can bring out behavioral changes but not always attitudinal changes.
