There seemed to be no end to the insights that could be offered under the banner of thinking outside the box.Speakers, trainers, training program developers, organizational consultants, and university professors all had much to say about the vast benefits of outside-the-box thinking.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).The symmetry, the beautiful simplicity of the solution, and the fact that 80 percent of the participants were effectively blinded by the boundaries of the square led Guilford and the readers of his books to leap to the sweeping conclusion that creativity requires you to go outside the box.The idea went viral (via 1970s-era media and word of mouth, of course).
Indeed, the concept enjoyed such strong popularity and intuitive appeal that no one bothered to check the facts.
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.
Although studying creativity is considered a legitimate scientific discipline nowadays, it is still a very young one. One of Guilford’s most famous studies was the nine-dot puzzle.
Guilford was one of the first academic researchers who dared to conduct a study of creativity.
