"Seeing What Everybody Has Seen and Thinking What Nobody Has Thought"
Szent-Györgyi is onto something important below. But I think it would be more accurate to say that we all experience dissonant events (but usually not the same dissonant events, as Szent-Györgyi implies), and that most of us let the events pass without noticing, or remembering, or making use of them. What is rare is to notice the events, remember them and make use of them. Those who carry around with them the burden of unsolved problems, and unfixed frustrations, are more likely to see in unexpected events solutions to those problems and fixes for the frustrations. This all takes the effort of our better self (what Kahneman calls our System 2). It takes effort to carry around the problems, to bear the dissonant observations, and to suffer the indifference of friends and the ridicule of experts. But it is through such effort that we better understand the world and, most importantly, that we improve the world.
