People generally think they can monitor and control their own thoughts and behavior. However, owing to the recent development of research methods in the field of social cognitive psychology, it became clear that people's attitude and behavior consists of conscious aspect (explicit attitude) and unconscious aspect (implicit attitude). The development of the IAT (Implicit Association Test) by Greenwald and Banaji (Greenwald & Banaji, 1995; Greenwald, McGhee, & Schwartz, 1998) enabled a number of research on implicit attitudes to be conducted. Accumulated results of the research have indicated the relationships between implicit attitudes and behaviors on prejudice, stereotype, depression and social anxiety, aggressiveness. The present article reviews previously conducted research on implicit attitudes, focusing on the implicit attitude and people's actual behavior. Then, based on this review, the applicability of this implicit measure, especially on social technology, is discussed.
