What is the importance of Berlin’s story, The Hedgehog and the Fox, in the nonfiction book, Thinking, Fast and Slow?

Philip Tetlock, a psychologist at the University of Pennsylvania, used Isaiah Berlin’s essay on Tolstoy, “The Hedgehog and the Fox,” to describe so-called experts who cannot admit to err and are enraptured by their own brilliance. Hedgehogs all know one big thing and “bristle” when someone disagrees. Hedgehogs are notorious for their inability to admit to being wrong and make excuses when things don’t go as they predict.

Foxes think in complexities and don’t ascribe to the hedgehog’s belief in just one big thing. Foxes believe that reality is a combination of many different elements and energy, the results of which cannot be predicted.
