course devoted entirely to the future was taught by the late Alvin Toffler at the New School in 1966. Modern futurists More generally, the label includes such disparate lay, professional, and academic groups as visionaries, foresight consultants, corporate strategists, policy analysts, cultural critics, planners, marketers, forecasters, prediction market developers, roadmappers, operations researchers, investment managers, actuaries, and other risk analyzers, and future-oriented individuals educated in every academic discipline, including anthropology, complexity studies, computer science, economics, engineering, urban design, evolutionary biology, history, management, mathematics, philosophy, physical sciences, political science, psychology, sociology, systems theory, technology studies, trend analysis, and other disciplines. Futurology "Futurology"—or "futures studies", futures research, and foresight—can be summarized as being concerned with "three P's and a W", i.e. "possible, probable, and preferable" futures, plus "wildcards", which are low-probability, high-impact events, should they occur. Even with high-profile, probable events, such as the fall of telecommunications costs, the growth of the internet, or the aging demographics of particular countries, there is often significant uncertainty in the rate or continuation of a trend. Thus, a key part of futures analysis is the managing of uncertainty and risk. Futurists and futurology Not all futurists engage in the practice of futurology as generally defined. Pre-conventional futurists (see below) would generally not. And while religious futurists, astrologers, occultists, New Age diviners, etc. use methodologies that include study, none of their personal revelation or belief-based work would fall within a consensus definition of futurology as used in academics or by futures studies professionals. Several authors have become recognized as futurists. They research trends, particularly in technology, and write their observations, conclusions, and predictions. In earlier eras, many futurists were at academic institutions. John McHale, author of The Future of the Future, published a "Futures Directory", and directed a think tank called The Centre For Integrative Studies at State University of New York in 1968. Futurists have started consulting groups or earn money as speakers, with examples including Alvin Toffler, John Naisbitt and Patrick Dixon. Frank Feather is a business speaker that presents himself as a pragmatic futurist. Some futurists have commonalities with science fiction, and some science-fiction writers, such as Arthur C. Clarke, are known as futurists. In the introduction to The Left Hand of Darkness, Ursula K. Le Guin distinguished futurists from novelists, writing of the study as the business of prophets, clairvoyants, and futurists. In her words, "a novelist's business is lying". A 2001 survey
