Abstract
An investigation was made regarding possible relationships among five extremity-confidence judgmental measures. The measures were determined from Kogan and Wallach's modification of Brim's “desire for certainty” questionnaire. For 40 hospitalized psychiatric patients it was found that confidence and judgmental extremity were positively related. Variability of confidence was not significantly related to any of the other measures whereas probability estimation variability was positively and significantly related to judgmental extremity and negatively related to probability estimation. Probability estimation was also positively and significantly related to confidence. Although correlation ratios, in addition to product-moment correlations were computed, no justification for regarding the observed relationships as other than linear was found.
