Neuroscientists at Cornell University recently discovered that engaging brain areas linked to so-called “off-task” mental activities (such as mind-wandering, daydreaming or reminiscing)—which are associated with the default mode network—can actually boost performance on some challenging mental tasks.
Why? Good question. It is likely to do with how much we get “stuck” in a given narrative. The brain has a tendency to get stuck, especially when it has to cope with intense emotions. Getting unstuck has value other than just creating movement. It helps you to find new narrative opportunities.
