Toward a Procedural Theory of Judgment.
Abstract
A procedural theory of judgment is described in which judgment is viewed as a serial 'anchoring and adjustment' process. The process is described as comprising scanning, anchoring, and adjusting operations, the latter of which is applied iteratively (with order of adjustment steps usually determined by relative importance) until the judge deems that sufficient information has been integrated and outputs a final response. The paper has three major sections. First, the procedural theory is described and contrasted with the implicit characterization of process that might be drawn from algebraic models of judgment. Next, three common forms of judgment are described (averaging rules, relative ratio rules, and multiplying rules) and discussed in terms of the factors that predispose subjects to 'use' those rules for particular tasks. Finally, several common phenomena to judgment (primacy and recency effects, initial impression effects, differential weighting effects and violations of additivity) are interpreted within the serial adjustment model.
