Author’s note: I regularly find myself assailed by questions about the future from business leaders, colleagues, and friends. They ask about companies, elections, technology, their own lives. Their questions imply that the future is knowable, hidden like the Wizard of Oz behind a curtain that only the fearless or gifted can pull aside. This strikes me as magical thinking, not least because research shows that the time horizon for accurate forecasting is shrinking: 400 days if you’re rigorous, closer to 150 days if you’re not.

This is a huge change whose impact few individuals or organizations have fully absorbed or understood. Yet even as our foresight shrinks, our addiction to prediction has grown.

A craving for certainty extracts a high cost: constricting our understanding, our imagination, and our freedom. In both our private and our working lives, how much more might we be able to do, to see and to be if we kicked the habit?
