Psychological Inertia

Until now, inventive problem solving was addressed by the field of psychology, where the links between the brain and innovation are studied. Methods such as brainstorming and trial-and-error are commonly used.

Let P represent a problem. A solution, S, lies somewhere in the solution space, but we do not know where. To find the solution we must first identify the direction that leads to it. We make an attempt in one direction (concept 1 and its variants) and fail. We make another attempt, and another, then another -- with the same result. If the solution happens to reside within our field of expertise or experience, the number of trials required will be relatively fewer. But if this is not the case, our search is likely to be difficult. For example, if a mechanical problem has a chemical solution, much time can be wasted exploring the direction of mechanics. This phenomenon, where familiar directions are pursued and alternative technologies go unexplored, is called psychological inertia. Psychological inertia can be a very time-consuming and destructive issue in the inventive process.

The table below explains why inventive problems are especially difficult to solve.
