Subjects judged "ratios" and "differences" of the prestige of occupations. "Ratio" and "difference" judgments were nearly monotonically related, consistent with the hypothesis that subjects used the same operation for both comparisons. To test the invariance of "ratio" judgments, different groups were exposed to different numerical examples of "ratios." When the largest "ratio" mentioned in the instructions was "4," the median and modal "ratio" of the prestige of physician relative to trash collector was 4. When the largest "ratio" mentioned was "64," the median and modal "ratio" judgment for physician relative to trash collector was 64. This malleability of "ratio" judg- ments compromises the ratio model of stimulus comparison, but is consistent with Birnbaum's theory that "ratio" judgments are governed by subtraction on the same interval scale that underlies "difference" judgments.
