SARAS SARASVATHY, A PROFESSOR at the University of Virginia’s Darden School of Business, has found that entrepreneurs are the polar opposite of pundits. One similarity among many entrepreneurs, she said, was an aversion to prediction. “If you give entrepreneurs data that has to do with the future, they just dismiss it,” she told Inc. magazine. Entrepreneurs don’t seem to believe that forecasting is worth the bother: One survey found that 60% of Inc. 500 CEOs had not even written business plans before launching their companies.
