This shortnote deals with measuring normative clearsightedness about internality and assessing its effects. After raising the issue of how to measure normative clearsightedness, another operationalization of this concept is proposed based on a multilevel model. In an attempt to understand the relationship between pupils' clearsightedness about internality and their teachers' judgments of them, empirical data was collected from 404 third-grade pupils and their 19 teachers. The estimates obtained point out the heuristic value of the proposed model. (Contains 2 figures, 3 tables, and 3 notes.)
