According to Costa, the author of The Watchman’s Rattle: A Radical New Theory of Collapse, what will save us all is the ability of the human mind to achieve insight. She writes of insight as it it is a new discovery. The notion of insight and an “aha” moment in solving problems goes back to the Gestalt psychologists at least. What is new is the identification cognitive structures involved in achieving insight.
Costa stresses that insight is a biological capability that we all have. She cites an article1 that describes an experiment in which the cognitive structures were identified. Nineteen experimental participants were asked to solve word problems while the activity in their brains was monitored. Three words were presented, such as pine, crab, and sauce, to each participant. The task was to think of another word that could be combined with each of these words to make three new words. For example, a solution to these words would be “apple,” to produce “pineapple,” “crabapple,” and “applesauce.” The participants did many of these problems and brain activity was tracked to identify and differences that signaled an insightful answer. When insight was used the anterior Superior Temporal Gyrus (aSTG) became highly excited producing a sudden burst of gamma oscillatory activity. This occurred 300 milliseconds in advance of solving the problem. They also discovered that the Anterior Cingulate Cortex (ACG), which is responsible for relaying signals between the left and right hemispheres of the brain, appears to suppress irrelevant thoughts prior to invoking insight. The notion is that insightful thinking is more vulnerable to external interference than is nonsightful processing necessitating greater suppression of external thoughts. When insight is achieved, the problem solver is confident of her insight. Insight is cognitively taxing. Increased electrical activity takes place in the left posterior M/STG, the anterior cingulate, the right posterior M/STG, and the amygdala. Costa argues that insight is the brain’s special weapon against complexity. A simplifying insight eliminates the complexity.
Insight and creativity are closely related. I would suggest that insight is a special type of creativity, one aimed and solving a particular problem. Insight is creative, but creativity also includes literature, fine art, music, and dance to name just a few activities.
