Alternatively, consensus has been used to assess the level of agreement among a set of forecasts. Higher consensus often implies higher accuracy, especially when the forecasts are made independently. Ashton (1985) examined two different forecast situations: forecasts of annual advertising sales for Time magazine by 13 Time, Inc. executives given forecast horizons for one, two, and three quarters, and covering 14 years; and forecasts by 25 auditors of 40 firms’ problems, such as bankruptcy. Using two criteria, correlation and mean absolute deviation, she compared the actual degree of agreement (between forecasts by different judges) against the accuracy of these judges. She also compared each judge’s degree of agreement with all other judges and related this to that judge’s accuracy. Agreement among judges did imply greater accuracy and this relationship was strong and statistically significant. This adds evidence for using consensus as a proxy for confidence.
