The correct solution, however, requires you to draw lines that extend beyond the area defined by the dots.At the first stages, all the participants in Guilford’s original study censored their own thinking by limiting the possible solutions to those within the imaginary square (even those who eventually solved the puzzle).It was an appealing and apparently convincing message.Indeed, the concept enjoyed such strong popularity and intuitive appeal that no one bothered to check the facts.It's an interesting experiment, but the author's conclusion cannot possibly follow from the results of it.
After all, with one simple yet brilliant experiment, researchers had proven that the conceptual link between thinking outside the box and creativity was a myth. But you will find numerous situations where a creative breakthrough is staring you in the face.
Let’s look a little more closely at these surprising results.
Solving this problem requires people to literally think outside the box.
Most people assume that 60 percent to 90 percent of the group given the clue would solve the puzzle easily. What’s more, in statistical terms, this 5 percent improvement over the subjects of Guilford’s original study is insignificant.
In other words, the difference could easily be due to what statisticians call sampling error.
