Malcolm Gladwell: Albert O. Hirschman and the Power of Failure : The New Yorker: Digging through the Hoosac turned out to be a nightmare. The project cost more than ten times the budgeted estimate. If the people involved had known the true nature of the challenges they faced, they would never have funded the Troy-Greenfield railroad. But, had they not, the factories of northwestern Massachusetts wouldn’t have been able to ship their goods so easily to the expanding West, the cost of freight would have remained stubbornly high, and the state of Massachusetts would have been immeasurably poorer. So is ignorance an impediment to progress or a precondition for it?
The economist Albert O. Hirschman, who died last December, loved paradoxes like this. He was a “planner,” the kind of economist who conceives of grand infrastructure projects and bold schemes. But his eye was drawn to the many ways in which plans did not turn out the way they were supposed to—to unintended consequences and perverse outcomes and the puzzling fact that the shortest line between two points is often a dead end.
