Abstract
The accident considered to have generated by man’s misunderstanding has happened. Examination of the process regards the man who cannot correct a misunderstanding as the tendency not to accept various support positively being strong. It is considered important to solve that it is that what man cannot actually correct a misunderstanding. This research examined exper imentally the feeling heuristics and the Less-is-better effect that a belief influenced judgment, using the individual-difference index that influencing two actions, action/state intention nature, and risk intention nature, is considered. As for an action intention-risk pursuit type man, a result cannot correct a misunderstanding, but the man of a state intention shows that risk pursuit type and evasion type all can correct a misunderstanding.
