Research Note: The Accuracy of Group Majorities for Disjunctive and Conjunctive Decision Tasks
نویسنده
چکیده
For complex group decision tasks which can be described in terms of establishing the truth value of conjunctive (and) or disjunctive (or) composite propositions, the advantage for group judgmental accuracy of disaggregating the decision task into separate individual evaluations of the truth value of each component atomic proposition in the composite is investigated. For true propositions it is shown that disaggregation is preferable for conjunctive tasks, but not for disjunctive tasks: while the reverse is true for false propositions.

An Empirical Study of the GIGO Axiom in Satisficing Decisions
An effort to improve data accuracy that yields poorer information accuracy when the data are processed would normally be labeled a major failure. While popular belief discounts the likelihood of such an event, research of conjunctive and disjunctive decision rules suggests that a negative association between input accuracy and decision accuracy is a deeply rooted phenomenon. In this paper we ex...

The influence of decision task and deliberation style on the verdict of the juries. In the Kameda's Deliberation Style Model the emission of verdicts of responsibility when the deliberation style of the juries (elemental/compound) and the type of decision task (disjunctive/conjunctive) are jointly manipulated, is favoured in certain conditions. Given the consequences that these approaches could...

This paper studies the eeects on decision tree learning of constructing four types of attribute (conjunctive, disjunctive, M-of-N, and X-of-N representations). To reduce eeects of other factors such as tree learning methods, new attribute search strategies, search starting points, evaluation functions, and stopping criteria, a single tree learning algorithm is developed. With diierent option se...
متن کاملThe Influence of Prior Theories on the Ease of Concept Acquisition
The finding that conjunctive concepts are easier for human subjects to learn than disjunctive concepts is reported in most introductory books on cognitive psychology. In this paper, we report some conditions under which this finding may not be true. In particular, we demonstrate that the prior causal knowledge of subjects can influence the rate of concept learning. We report on an experiment th...
متن کاملThe Asymmetric Nature of Decision Errors in Multi-Criteria, Satisficing Decisions
This paper centers on an asymmetry, or bias, in the accuracy of multi-criteria, conjunctive and disjunctive decisions, which originates from fundamental properties of the logical conjunction and disjunction operations. A series of Monte Carlo simulations demonstrates that, as we keep adding criteria to a multi-criteria satisficing decision rule, errors in the data produce decision errors asymme...
