Analyzing the expert judge: A descriptive study of a stockbroker's decision processes
This study illustrates an analysis-of-variance technique for describing the use of information by persons making complex judgments. Ss were two stockbrokers who rated the growth potential of stocks on the basis of 11 factors taken from Standard & Poor reports. The technique proved capable of providing a precise quantitative description of configural and nonconfigural information utilization. Each broker exhibited a substantial amount of configural processing. The technique appears to have promise for providing experts with insight into their own processes and for teaching and evaluating "student" judges.
