The Delphi technique: An experimental evaluation

Abstract Much research has been devoted to the Delphi technique. However, very little substantive work has been done on the subject of Delphi accuracy. The purpose of this effort was to test the accuracy of Delphi vs the conference method in making long-range forecasts. College students were used to form Delphi and conference groups that predicted the point spreads of college football games far in advance of play. The results substantiate the claim that Delphi outperforms conference methods on the basis of accuracy for long-range forecasting.
