Indeed, the concept enjoyed such strong popularity and intuitive appeal that no one bothered to check the facts.
He challenged research subjects to connect all nine dots using just four straight lines without lifting their pencils from the page.
Today many people are familiar with this puzzle and its solution.
That this advice is useless when actually trying to solve a problem involving a real box should effectively have killed off the much widely disseminated—and therefore, much more dangerous—metaphor that out-of-the-box thinking spurs creativity.
