Guilford was one of the first academic researchers who dared to conduct a study of creativity.He challenged research subjects to connect all nine dots using just four straight lines without lifting their pencils from the page.Because they hadn’t, they were obviously not as creative or smart as they had previously thought, and needed to call in creative experts. The nine-dot puzzle and the phrase “thinking outside the box” became metaphors for creativity and spread like wildfire in marketing, management, psychology, the creative arts, engineering, and personal improvement circles.There seemed to be no end to the insights that could be offered under the banner of thinking outside the box.
Let’s look a little more closely at these surprising results.
The second group was told that the solution required the lines to be drawn outside the imaginary box bordering the dot array.
In other words, the “trick” was revealed in advance.
Today many people are familiar with this puzzle and its solution.
In the 1970s, however, very few were even aware of its existence, even though it had been around for almost a century.
