This study aims to critically examine and suggest the concept of moral expertise of moral psychologist D. Narvaez. To this end, I analyze the concept of psychological expertise borrowed from Narvaez, in particular, by comparing her concept of moral expertise. The analysis is divided into individual internal and social aspects. In the individual internal aspect, the axis focuses on 1) area specificity of expertise and 2) biological characteristics of expertise. On the social side, we compare the behavioral patterns of groups and other groups that can be recognized as moral experts with moral expertise to examine the ecological validity of the moral expertise concept for moral education. To do this, we compare 1) crime rates among professed religious people and other occupational groups, and 2) examine moral behavior patterns of ethics researchers and other major researchers. This study includes narvaez s response to the analysis and the researcher s review. In the end, D. Narvaez s concept of
moral expertise needs to be revised and supplemented before it is applied to the educational field as an integrated moral education discourse. And Suggesting that the concept should be replaced ‘Moral Connoisseurship’.
