This paper revisits the use of trend forecasting in driving policy in social systems by comparing it with
derivative control in classical control theory. While both processes involve use of trend to determine
policies for achieving reliable performance, the outcomes of the former have considerable variability while
those of the later can create improvement in performance with certainty. The similarities and differences
between the two processes are discussed and guidelines suggested for improving the efficacy of trend-
forecasting in policy design in social systems.
