The notable advance in recent years in the recognition and treatment of the uncertainty inherent in management problems has tended to have a curious backlash. Out of the new methodology has come, for many technicians and too many managers, a strange belief in the absolutism of the ultimate optimizing solutions.

Most parameters in the humanities are essentially the "facts" of yesterday; undue confidence in their predictive value calls for a reminder of man's fallibility in a world of uncertainty.
