Passage Seven (Forecasting of Statistics) Nearly two thousand years have passed since a census1 decreed by Caesar Augustus become part of the greatest story ever told. Many things have changed in the intervening years. The hotel industry worries more about overbuilding than overcrowding, and if they had to meet an unexpected influx2, few inns would have a manager to accommodate the weary guests. Now it is the census taker that does the traveling in the fond hope that a highly mobile population will stay long enough to get a good sampling. Methods of gathering3, recording4, and evaluating information have presumably been improved a great deal. And where then it was the modest purpose of Rome to obtain a simple head count as an adequate basis for levying5 taxes, now batteries of complicated statistical6 series furnished by governmental agencies and private organizations are eagerly scanned and interpreted by sages7 and seers to get a clue to future events. The Bible does not tell us how the Roman census takers made out, and as regards our more immediate8 concern, the reliability9 of present day economic forecasting, there are considerable differences of opinion. They were aired at the celebration of the 125th anniversary of the American Statistical Association. There was the thought that business forecasting might well be on its way from an art to a science, and some speakers talked about newfangled computers and high-falutin mathematical system in terms of excitement and endearment10 which we, at least in our younger years when these things mattered, would have associated more readily with the description of a fair maiden11. But others pointed12 to the deplorable record of highly esteemed13 forecasts and forecasters with a batting average below that of the Mets, and the President-elect of the Association cautioned that “high powered statistical methods are usually in order where the facts are crude and inadequate14, the exact contrary of what crude and inadequate statisticians assume.” We left his birthday party somewhere between hope and despair and with the conviction, not really newly acquired, that proper statistical methods applied15 to ascertainable16 facts have their merits in economic forecasting as long as neither forecaster nor public is deluded17 into mistaking the delineation18 of probabilities and trends for a prediction of certainties of mathematical exactitude. 1.
