The application of Weber's Law to job evaluation estimates

Abstract

It has been found that the judgment expressed in factor comparison job ratings seems to behave in accordance with Weber's Law in that arithmetic intervals in job difficulty are matched by logarithmic increments in salary. Data show that "just noticeable differences" which were correctly discriminated by trained job raters about 3/4 of the time were 15% apart in salary value of the factor interval.
