The practice of Inochi-tendenko is extremely effective in saving lives. Though this practice has been highly featured since the Great East Japan Earthquake on March 11, 2011, the degree to which people recognize its effectiveness remains low, and very little empirical analysis has focused on the psychological barriers to its practice. Using a newly developed paradigm of a supposed sediment-disaster dilemma, we show that emotional judgment in system 1 decision-making is a key psychological determinant of the hesitation to practice Inochi-tendenko. We also attempt to experimentally demonstrate one possible way to control such emotional judgment. We believe our findings have implications for disaster-prevention education and discuss possible concrete ways to provide education on the practice of Inochi-tendenko based on these findings.
