Group decision support systems implement Bayesian rationality
Author: Sinclair-Desgagné, Bernard INSEAD Area: Technology and Operations ManagementIn: European Journal of Operational Research, vol. 47, no. 1, July 1990 Language: EnglishDescription: p. 29-34.Type of document: INSEAD ArticleNote: Please ask us for this itemAbstract: When saying that group decisions are good, one often means that they are "externally Bayesian". Proposed by Madansky (1964), the externally Bayesian criterion requires that the decisions of the group look as if they were chosen by a Bayesian individual. A process due to De Groot (1974) satisfies this criterion. It is argued that this process corresponds to a group decision support system. This reinforces the claim that group decision support systems can improve group decision making| Item type | Current location | Call number | Status | Date due | Barcode | Item holds |
