Mark Jung-Beeman is a cognitive neuroscientist at Northwestern University, and he has studied what happens inside the brain when people have an insight. He was quoted in a recent New Yorker article, saying: “If you want to encourage insights, then you’ve got to also encourage people to relax.” The article notes that “Jung-Beeman’s latest paper investigates why people who are in a good mood are so much better at solving insight puzzles.”

What Jung-Beeman has discovered is that insight and creative solutions can be inhibited or blocked by being overly focused. Instead, what is often needed for insight is to focus on not focusing. The article continues, “As Jung-Beeman and Kounios [a cognitive neuroscientist at Drexel University] see it, the insight process is an act of cognitive deliberation — the brain must be focused on the task at hand — transformed by accidental, serendipitous connections. We must concentrate, but we must concentrate on letting the mind wander.”
