| Abstract: | In a study investigating the relative impact of "task and instititutional influences on managers' mental models of competition", Daniels et al. (2002) elicited cognitive maps using two complementary ideographic mapping procedures: a card-sort technique and a variant of the repetory grid. Given that the resulting individual maps were each based on differing organizations and attributes, Daniels and his colleagues assessed belief similarity - their key dependent variable - by asking their participants to rate the overall similarity of the various maps so elicited to their own mental models which prevailed at the time the comparative rating exercise was subsequently performed, some three to six months later. The author of this paper draws on research into the cognitive processes underpinning similarity judgments, and argues that this approach to the comparison of cognitive maps suffers from a number of severe limitations which are likely to bias the results in favor of the research hypotheses under test, thus leading to increased type 1 errors. |
