In 1982 the St. Louis Business Journal tested how a psychic would fare against professional stockbrokers over a six-month period, and reported that the psychic, who had no formal training in stock market trading or analysis, outperformed eighteen of nineteen professional stockbrokers. During the testing period, the Dow Jones Industrial Average fell 8 percent, but the psychic's stocks went up 17 percent.
The use of psi to enhance decision making is not overlooked in the intensely pragmatic world of Wall Street. In 1985 a vice president of Shearson Lehman Brothers provided a good summary of how results-oriented business views psi. In a full-page article in the New York Times business section, Chester Rothman observed that "If a psychic can better grasp the rationalities of the world than a market analyst, he might well give better business advice. Successful entrepreneurs and investment analysts have confided to me that psi techniques, especially precognition, are beginning to play an increasingly important role on Wall Street. The driving force is that everyone now uses sophisticated computer models to help forecast which stocks to pick, so to maintain a slight edge in the accelerating world of stock trading, analysts and brokers need methods that outforecast the computers. Some brokers are successfully using psi to help nudge the computers' mathematical models, and the tiny forecasting advantages they gain are reportedly resulting in enormous profits. No wonder they've kept quiet about their interests!
