Why Sleep is Essential to Creativity

Art Markman, Professor of Psychology and Marketing at the University of Texas at Austin, has written an informative article for Fast Company regarding the relationship between sleep and creativity.  Markman writes the following:

To understand how, it is helpful to know a bit more about creativity. When you are trying to develop a creative solution to a difficult problem, you need to find some knowledge that you already have that will help you take a new approach. That means that a big part of creativity is allowing the problem to remind you of things you know about that probably come from another area of your expertise and that are relevant to your current problem. In short, you are seeking a good analogy.

 

Why then does getting a good night's sleep matter? Markman explains that, when you sleep, your memories are consolidated.  The brain does not remember everything about your day.  It has a way of retaining the most crucial events, ideas, and interactions.  If you want to be creative, and perhaps discover a relevant analogy, you do not want your thinking cluttered with non-essential information.  Getting a good night's sleep helps your brain sort out what's important and what is not essential.  In that way, you have a better shot at discovering that key analogy that might lead to a creative breakthrough.   

What is Critical Thinking?

The Wall Street Journal published a terrific article by Melissa Korn this week.   The article focuses on the fact that many executives say that they want to hire people with "critical thinking" skills. However, the definition of that term seems elusive.  In fact, some people don't have a clear definition of the term. Others disagree over the meaning of critical thinking skills.   Perhaps, the article suggests, you simply know them when you see them.   The article does offer a few intriguing definitions of the term:

• “The ability to cross-examine evidence and logical argument. To sift through all the noise.”
  -Richard Arum, New York University sociology professor
• “Thinking about your thinking, while you’re thinking, in order to improve your thinking.”
  -Linda Elder, educational psychologist; president, Foundation for Critical Thinking
• “Do they make use of information that’s available in their journey to arrive at a conclusion or decision? How do they make use of that?”
  -Michael Desmarais, global head of recruiting, Goldman Sachs Group
