Since time immemorial, people have tried to predict the future. In the second half of the 20th century, these efforts grew more ambitious and sophisticated. Improvements in computational power, data gathering, and analysis were all put to work to try to lift the veil on the future. But the last decade has not been kind to futurology. Bankers' and insurers' forecasts of risk turned out to be drastically wrong, torpedoing the financial system and ushering in a long stagnation. Politicians' visions of long-term stable economic growth evaporated. Perhaps relatedly, scathing critiques of our ability to foresee the future rose to the top of bestseller lists. In this newly self-conscious mood, Nesta funded research that tries to get under the surface of different ways of talking about the future. This paper leans on that research, defending some forms of futurology. Accompanying Guardian post on uncertainty being the only certainty.
