You probably know someone who thinks they know more about something than they really do. But you could never be described that way . . . could you? This week, cognitive scientist Phil Fernbach explains the "illusion of knowledge" — the fact that we think we understand the world in much greater detail than we actually do. He'll explore why this happens, and how to close the gap between what we know and what we think we know. Hidden Brain is about to go on tour! Join Shankar in a city near you as he shares key insights from the first decade of the show. For more info and tickets, go to https://hiddenbrain.org/tour/
Full Episode
This is Hidden Brain. I'm Shankar Vedanta. Some months ago, I brought seven key insights from the first decade of Hidden Brain to live stage performances in San Francisco and Seattle. The evenings were electric. We got so much positive feedback from those two sold-out shows that we've decided to launch a tour to more than a dozen cities in the coming months.
I'll be coming to Portland, Denver, Minneapolis, Chicago, Austin, Dallas, Boston, Toronto, Clearwater, Fort Lauderdale, Phoenix, Baltimore, Washington, D.C., and Los Angeles. To snap up your tickets, please go to hiddenbrain.org slash tour. You can also sign up to say hello and get a photo with me. In some places, you can sign up for an intimate chat with me and a handful of other fans.
I'd love to see you there. Again, go to hiddenbrain.org slash tour.
Okay, on to today's show. This is Hidden Brain. I'm Shankar Vedantam.
Almost exactly a century ago, a British ship, the Endurance, became trapped in Antarctic sea ice. Aboard were 28 men, led by the explorer Ernest Shackleton. On October 27, 1915, the pressure of the ice crushed the keel of the Endurance. Freezing water rushed in. The sailors dragged lifeboats and supplies from the ship onto the ice. Carrying the lifeboats, they started hiking toward open water.
After a week with little progress, Ernest Shackleton realized they would be better off camping on an ice floe and waiting for it to drift toward open water. What followed was an extraordinary story of knowledge and resourcefulness. The explorers managed to get their lifeboats into the water and row to dry land, a place called Elephant Island.
But the desolate island offered little by way of resources and no hope of rescue. So Ernest Shackleton and a smaller group took one of the lifeboats and set out for a whaling station. It was 800 miles away. Across seas were towering waves and deadly storms. The explorers had only basic navigation equipment. Somehow, using the stars to guide them, they made it to the island of South Georgia.
But storms had blown them to the wrong side of the island as the whaling station. They now had to hike across the island, across frozen mountains and icy glaciers, to reach help. Ernest Shackleton eventually commanded a ship back to Elephant Island to rescue the remainder of his crew. He saved every last man. This is the kind of story that is popular in novels and movies.
The explorers came up with creative solutions to problems and displayed a deep understanding of the challenges before them. They kept their heads and saved themselves. Stories like this obscure how much we understand about our own worlds.
