The first group was given the same instructions as the participants in Guilford’s experiment.
The second group was told that the solution required the lines to be drawn outside the imaginary box bordering the dot array.
What the latest experiment proves is not that creativity lacks any association to thinking outside-the-box, but that such is not conditioned by acquired knowledge, i.e., environmental concerns.
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).
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.
