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.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.Yet participants’ performance was not improved even when they were given specific instructions to do so.
Would you like to guess the percentage of the participants in the second group who solved the puzzle correctly?In the 1970s, however, very few were even aware of its existence, even though it had been around for almost a century.If you have tried solving this puzzle, you can confirm that your first attempts usually involve sketching lines inside the imaginary square.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.He challenged research subjects to connect all nine dots using just four straight lines without lifting their pencils from the page.
