Why Daydreaming Makes You Smarter And More Creative

Although Schooler has previously demonstrated a correlation between daydreaming and creativity—those who are more prone to mind-wandering tend to be better at generating new ideas, at least in the lab—this new paper shows that our daydreams seem to serve a similar function as night dreams, facilitating bursts of creative insight. Take a 2004 paper published in Nature by the neuroscientists Ullrich Wagner and Jan Born. The researchers gave a group of students a tedious task that involved transforming a long list of number strings into a new set of number strings. Wagner and Born designed the task so that there was an elegant shortcut, but it could only be uncovered if the subject had an insight about the problem. When people were left to their own devices, less than twenty per cent of them found the shortcut, even when given several hours to mull over the task. The act of dreaming, however, changed everything: after people were allowed to lapse into R.E.M. sleep, nearly sixty per cent of them discovered the secret pattern. Kierkegaard was right: sleeping is the height of genius.

A daydream, in this sense, is just a means of eavesdropping on those novel thoughts generated by the unconscious. We think we’re wasting time, but, actually, an intellectual fountain really is spurting.
