An Impossibility Theorem for Group Probability Functions.
ResearchPublished 1972
Aggregation functions which generate a group estimate based on a set of individual estimates have become of general interest for many decision problems where the best information available is the estimates of a group of experts. The question rather naturally arises whether a function can be defined which is consistent with the postulates of probability theory when the individual estimates are probabilities. The theorem is proved that under several natural assumptions, there is no aggregation function for individual probability estimates which itself is a probability function. 6 pp. Bibliog.

This publication is part of the RAND paper series. The paper series was a product of RAND from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
