Si les insomnies d’un musicien lui font créer de belles oeuvres, ce sont de belles insomnies.~ Antoine de Saint-Exupéry
I’ve been wondering about creativity lately.
In 1926 Graham Wallas proposed a model to describe the process of creativity. This model followed four steps: 1) Preparation, 2) Incubation, 3) Illumination, and 4) Verification. There are two reasons why this model is historically important. First is the implication that creativity can be structured to some degree, and thus directed towards particular ends. The second is the recognition that creativity works both consciously and subconsciously, or a mix of directed and undirected thinking.
For many, the idea that creativity can be structured or controlled to some degree is of great significance. Think of the need in business to be innovative in order to remain competitive. Much has been written in this area and it is fascinating stuff. The mystery, though, is the subconscious aspect of creativity.
When we think about the game of chess we might assume that a pure Spock-like logical mind would be the best. Chess is a game of carefully calculated moves designed to find advantages against an opponent until a win is secured. But a pure emotionless rationality doesn’t work in chess. Sure, Deep Blue, the super computer that was able to beat the world’s greatest chess champion, Gary Kasparov, had no emotion, but it could also calculate around 2 million possible moves per second. Kasparov, on the other hand, can only calculate around 5 moves per second. (Even then, Kasparov still won one game and drew three out of six against Deep Blue). The human brain has limitations when it comes to the heavy lifting kinds of work that computers can do. Therefore, us humans need (and have) a different process for calculating chess moves. The answer, surprisingly, is the role our emotions and subconscious play in the decision making process.
Our subconscious is an interesting animal when it comes to creativity. When we tackle a problem our conscious mind is actively engaged, even working overtime. But so is our subconscious. When we get stuck and can’t find a solution we may disengage our conscious mind and move on to something else, but our subconscious mind can still be working on the problem. That’s why solutions often hit us when we are far from problem solving mode – like when we are just about to fall asleep at the end of a long day. Moments like these are examples of undirected thinking. Often it is best to get away from problem solving mode and do mundane activities like checking email or going for a walk, in order to let one’s subconscious to percolate on the problem.
There is an interesting story of undirected thinking in a recent chess tournament. Every year a number of the world’s top chess players gather in the Dutch seaside town of Wijk aan Zee for the Corus Chess tournament. In 2010 the reigning U.S. champion, Hikaru Nakamura, was tearing up the tournament, and not without a little smugness. Former world chess champion Vladimir Kramnik was to play Nakmura next. The night before Kramnik was pondering his strategy. He suspected the kind of chess opening Nakmura would choose, but he was struggling to find a way to neutralize that choice. He worked on it all afternoon and finally had to take a break. Later, in a classic moment of undirected thinking, the solution hit him:
“Around 3 o’clock last night I was pretty annoyed. I hadn’t found anything yet and it’s not possible you can equalize with the Dutch. Finally I had a shower, where I realized that I just shouldn’t take on e4!”
Saying he shouldn’t take on e4 is a way of describing in chess language that the solution against Nakamura is to not fall into the trap set by Nakamura’s opening strategy. In other words, even though he needed to take a break from actively thinking about his upcoming game, Kramnik’s subconscious continued on towards a solution which then came to him in the shower. The next day Nakamura played the opening Kramnik was expecting and Kramnik was able to handily neutralize the opening and play on to a win.
We have all had moments like that where, when we least expect it, a solution pops into our head as though out of nowhere. The fact is, it was there, just not in our conscious mind, but in our subconscious. The story above goes to show as well that even in the profound mental struggles of world class chess the human mind works as it does for all of us, as a mix of conscious and subconscious activities that can lead to both logically calculated thoughts as well as flashes of intuition. It is all part of how our rationality works, and the more we understand its complexities the better we might be able to exploit both directed and undirected thinking in a holistic creative process.
If you are interested in hearing Vladimir Kramnik talk about his win against Hikaru Nakamura, you can view his post-game press conference below. Note: If the credits at the beginning say “Round 1 Jan Smeets…”, that’s a mistake. This is all Kramnik.
