Add to ORKGAn experiment designed to discover whether Delphi the results of laboratory studies dealing Forecasting with general (almanac) information are relevant to the applied case t-'en the true answer is unknown. Using short-range prediction questions as subject matter, the experiment indicates that, in general, Delphi procedures are at least as effective with short-range prediction as they have been for almanac material. Eight groups, of about 20 each, of upperclassmen and college graduates were given short-range prediction questions to answer in a 2-round Delphi exercise. Satisfactory answers were obtained for 32 of the 40 questions. Correlations between standard deviation and &ccuracy, and between group self-rating and accuracy, were s...
