How Creativity Occurs

Conception of a new idea often occurs in an intuitive flash of insight, in which the more or less complete idea is revealed. Equations and logical analysis come later. Someone who is reading scholarly publications in a library sees the final result in a format that is quite different from its initial conception. The fact that the public presentation is different from the way the idea initially occurred can lead to misunderstandings about how science is actually accomplished.

One of the principal ways to be creative is to look for alternative ways to view a phenomena or for alternative ways to ask a question. It is easy to ask questions that are trivial to solve. It is easy to ask questions that require extraordinary effort (e.g., 50 man-years of effort and millions of dollars in expenses) to solve. It is surprisingly difficult to find questions that lie in between these two extremes, and also have a result that is worth knowing.

One often-cited example of creativity is George de Mestral's observation of how cockleburs attach to clothing, which led him to invent the hook-and-loop fastener known as Velcro®. He transformed a common nuisance to a useful product. When one looks backward in time to analyze how a creative act was made, one often finds that creators made a novel interpretation of a well-known fact or occurrence. Often the interpretation converted a disadvantage into an advantage.

Another commonly cited example of creativity is Art Fry's development of Post-It® removable notes at 3M Corporation in 1974. Dr. Spencer Silver, another 3M scientist, had developed a polymer adhesive that formed microscopic spheres instead of a uniform coating, and thus was a poor adhesive that took years to set. Fry wanted a better bookmark for his church hymnal, so he used Silver's adhesive. The conventional wisdom is that every adhesive must be strong. By ignoring the conventional wisdom, Fry developed a highly successful office product. However, not only did he need to develop the idea, but he also had to sell the idea to his management and marketing departments, which were resistant to his new idea. A creative manager, if there be such a person, would have redefined the problem to find a use for a weak adhesive, but the conventional wisdom that all adhesives must be strong is apparently overpowering. There is a second exception to the "all adhesives must be strong" rule: thread locking compounds that prevent machine screws and bolts from loosening during vibration must be weak enough to allow removal of the screw or bolt during repair.

Prof. David Swenson has posted a web page with a rich collection of examples of innovation.
