In an age of uncertainty, those who can anticipate revolution, the outbreak of wars, or which states might default are much in demand. The marketplace of ideas about the future is huge, and includes "wonks", scholars and pundits who produce scenarios, predictions and ratings. The more opaquethe future seems to be, so the relation between knowledge and power intensifies, above all the nexus between those who sell their expertise and those who consume it. In his investigation of the paradoxes of forecasting, Ariel Colonomos interrogates today's knowledge factories to reveal how our futures are shaped by social scientists, think tanks and rating agencies. He explains why conservative and linear predictions prevail, and why the future, especially whenlinked to national interest, reflects a systematic search for stability. The notion of a globalized world whose main characteristic is speed, and where predictions have accelerating, self-fulfilling effects, is obsolete. Those who are supposed to know, reassure those who are supposed to act. Theirpreferences converge, and thus the industry of the future has a decelerating effect on world politics. These "lords of knowledge" reinforce pre-existing beliefs, create expectations about the future, while obstructing its vision when - inevitably - it diverges from its orderly path.
