Some Behavioural Aspects of Information Use in Decision Making: A Study of Clinical Judgements
This study investigates the behavioural uses of informational cues in clinical decision making. A sample of experienced physicians was asked to assign probabilities for accepting a given diagnosis on the basis of case profiles. Judgement processes of individuals were modeled. The investigation focused upon the selective use and value of cues in the diagnostic process with a special focus upon the impact of redundant information on judgements. Results suggest that decision makers do respond to cues selectively; even, at times drawing inconsistent inferences from different subsets of cues containing the same information. The study imples that information system designs should explictly take account of variations in the individual information structures of users (or perhaps, users should be trained to conform in their behavior to the theory(!)).
