President Obama recently admitted that he was wrong to rely heavily on the emergency plans of oil executives in the immediate aftermath of the Deepwater Horizon oil spill. It’s an admission that presidents don’t utter very often, but why?

Kathryn Schulz, author of “Being Wrong: Adventures in the Margin of Error”, says it’s refreshing to see a sitting president admit he was wrong, and that there are a lot of benefits to being mistaken, such as the joys of discovery, creativity and humility.
