Psychology This study was done to determine the effects of increasing information on the reliability of decisions. One hundred paid volunteers, graduating seniors at Bowling Green State University, made judgments on the desirability of hypothetical jobs. In one condition subjects were given either 3, 5, 7, 10, 15, or 25 cues and asked to make an overall evaluation of the job being described. In a second condition, the hierarchical condition, other subjects were given either 7, 10, 15, or 25 cues and asked to make preliminary decisions on subsets of these cues. They then made an overall evaluation of the job based on these preliminary decisions. A 2x4 MANOVA revealed a significant main effect for consistency (the linear predictability of a holdout set of decisions predicted using a multiple regression equation derived from a validation sample), reliability (rtt), and standard deviation for the set of decisions. Regression analyses showed a significant negative linear relationship between these variables and the number of cues presented indicating a change in decision quality as a function of number of cues. There was no significant effect for decision condition. Analysis of ratings showed that contrary to previous findings, there was no relationship between number of cues presented and confidence in the final decision. There was a significant and quite decided preference for the hierarchical decision format. These results highlighted three major issues. The first was that there was a powerful effect of amount of information on the reliability of decisions. The second was that people may feel they need more information than is optimal for reliable judgments. Finally, it is felt that there is a practical benefit to distinguishing between two types of judgments: Utility judgments (those for which an index of accuracy is either not available or irrelevant) and Environmental judgments (those for which an external criterion is available). In this study a unique method of determining the number of cues a subject used was employed using cross-validated step-wise multiple regression equations. Although the method tended to overestimate this index, there were indications that it warrants more scrutiny and may provide a useful tool for other investigations. 1978 English text Bowling Green State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=bgsu1566463066597406 http://rave.ohiolink.edu/etdc/view?acc_num=bgsu1566463066597406 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
