Accurate measurement of wisdom is the cornerstone of wisdom research. To provide a representative reference for the reliability level and moderating factors of various wisdom self-rating scales, we carried out a reliability generalization meta-analysis of Chinese and English references retrieved from 2004 to 2023. A total of 149 articles were included, as well as seven wisdom self-rating scales. The results showed that all seven wisdom self-rating scales had good internal consistency reliability. The reliability of the original scale was higher than that of the simplified version, and the reliability of the total of the original scale was higher than those of each dimension. Future research should avoid "reliability introduction," and rather focus on cross-cultural translation of the wisdom scale, selecting the most appropriate measurement tool for the particular field of wisdom, and strengthen theoretical interpretations by connotation and structure of wisdom itself.
