“When you start becoming reflective about the process, it undermines your ability. You lose the flow. There are certain kinds of fluid, intuitive, nonverbal kinds of experience that are vulnerable to this process.” As human beings, we are capable of extraordinary leaps of insight and instinct. We can hold a face in memory, and we can solve a puzzle in a flash. But what Schooler is saying is that all these abilities are incredibly fragile. Insight is not a lightbulb that goes off inside our heads. It is a flickering candle that can easily be snuffed out.
