Bastian July writes: In May 1968, the submarine USS Scorpion disappeared after a tour of duty in the North Atlantic. The initial search area was a circle twenty miles wide and thousands of feet deep. Instead of asking one or two experts for input, Navy officer John Craven assembled a large group of independent experts with a wide range of knowledge. The group included mathematicians, submarine specialists, salvage men and many others. Combining their knowledge, Craven was able to estimate the submarine’s likely location. It was found 200 yards from the group’s collective estimate. But can you also turn to the Wisdom of the Crowd when it comes to discovering the fortunes lying hidden in patents?
