Fuzzy set Quality Comparative Analysis (fsQCA) is gaining popularity in social studies. FsQCA uses set theory to describe the sufficient relationship between the combination of antecedents and outcome. Hence, the assessment of the relationship is very important. One of the functions is called consistency. FsQCA consider the sufficient relationship as a subset relationship, which is different from the relationship in logic. This study aims to re-examine the function of consistency and propose a new function. A data set is used to demonstrate process. The new consistency suits logic theory and yields more combinations of antecedents than those of the current consistency.
