Group Decision Analysis

Abstract

Delphi, as a procedure for aggregating judgments under certainty, has suffered from the lack of an underlying theoretical framework, especially one that relates group estimates to decision processes. It is shown that consistent group preference functions can be formulated by the use of anchored scales, i.e. , individual preference scales with fixed reference objects. A justification for the use of group probability judgments can be made, based on a family of theorems to the effect that the accuracy of a group judgment is always greater than (or at worst equal to) the average accuracy of the individual judgments.
