If the history of creativity teaches us anything, it is that great ideas often come when we’re least expecting them. Consider Wolfgang Amadeus Mozart, who described how new melodies would arrive while he was eating in a restaurant, walking after a meal or getting ready for sleep at night. “Those that please me, I retain, and even hum; at least, so others have told me,” he wrote. “It seems to me impossible to say whence they come to me and how they arrive; what is certain is that I cannot make them come when I wish.”
It’s not just Mozart who experienced this phenomenon; the French mathematician Poincare described how his breakthroughs occurred while travelling on the bus or walking by the seaside, while Agatha Christie reported that ideas for her crime stories often came while washing up or having a bath. “I don’t think necessity is the mother of invention,” she wrote in her autobiography. “Invention, in my opinion, arises directly from idleness, possibly also from laziness.”
Psychologists would seem to agree, with strong evidence that creative insights are much more likely to occur after a period of “incubation” – in which you focus on something entirely different from the job at hand, while your brain works away behind the scenes. This could include taking a walk, doing household chores or having a shower. Even our procrastination at work – such as watching funny YouTube videos – may be helpful for our problem solving, provided it is done in moderation.
Free thinking
There are many reasons why a period of incubation could lead to new and inventive insights. According to one of the leading theories, it depends on the power of the unconscious mind: when we leave our task, the brain continues to look for solutions below awareness, until a solution pops out.
