“A growing literature in the psychology of perception has demonstrated that, when it comes to certain difficult visual tasks — exercises where subjects are asked to locate a target shape in the midst of a large array—simply relaxing and letting the answer “pop out” works much better than actively trying. Similarly, when one is stymied by a problem, simply leaving it alone and doing something else is often the best way to solve it. Doing nothing allows your unconscious to take over, and, as we’ve seen, the unconscious is often better at solving certain types of particularly complex problems.”
