Human judgment researches have the central objective which is to help people improve the accuracy of human judgment and the quality of decision making. Although the attention of human judgment research was to the accuracy of human judgment after the term heuristic had been advocated in the psychological context, it came to shift to human judgment process for examining determinants of the accuracy of human judgment experimentally. Recently, there are, however, various conceptions of human judgment process, called Dual Process Theories, which are subtly different each other. The objective of this research is clarifying how we can examining determinants the accuracy of human judgment. Through this research, several articles on human judgment process were reviewed conceptually and experimentally. It was found that there is a future work to build a methodology to use the conception of human judgment process for examining determinants of the accuracy of human judgment. This research also proposed the dichotomy of human judgment process which is mutually exclusive and clearly defined: a process which is automatic and unconscious and a process which is a reasoning and conscious. The achievement of this study is hoped to further producing methodologies for examining determinants of the accuracy of human judgment.
