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).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.
Speakers, trainers, training program developers, organizational consultants, and university professors all had much to say about the vast benefits of outside-the-box thinking.
They are much more common than you probably think.*From Inside the Box: A Proven System of Creativity for Breakthrough Results Copyright 2014 Drew Boyd There are many theories of creativity.
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.
It's an interesting experiment, but the author's conclusion cannot possibly follow from the results of it.
your conclusion: that the second experiment disproves the theory that thinking outside the box is useful in solving problems, is itself a fallacy.
