Our level of creative success may be tied to what we can forget. As new models emerge our tendency is to layer them onto old models rather than jettison old things and start over. It’s much harder to face the the stark kernel of a new model. We wind up retrofitting our old models w new baubles instead of building sleek efficient new models.
- Divergent thinking to learn and explore
- Convergent thinking to select and synthesize
When you try to solve a problem, you begin by concentrating on obvious facts and familiar solutions, to see if the answer lies there. This is a mostly left-brain stage of attack. If the answer doesn’t come, the right and left hemispheres of the brain activate together. Neural networks on the right side scan remote memories that could be vaguely relevant. A wide range of distant information that is normally tuned out becomes available to the left hemisphere, which searches for unseen patterns, alternative meanings, and high-level abstractions.
Having glimpsed such a connection, the left brain must quickly lock in on it before it escapes. The attention system must radically reverse gears, going from defocused attention to extremely focused attention. In a flash, the brain pulls together these disparate shreds of thought and binds them into a new single idea that enters consciousness. This is the “aha!” moment of insight, often followed by a spark of pleasure as the brain recognizes the novelty of what it’s come up with.
Now the brain must evaluate the idea it just generated. Is it worth pursuing? Creativity requires constant shifting, blender pulses of both divergent thinking and convergent thinking, to combine new information with old and forgotten ideas. Highly creative people are very good at marshaling their brains into bilateral mode, and the more creative they are, the more they dual-activate.
- Sticking too close to home so that your solutions tend to be repackaged version of old methodologies?
- Venturing far afield and never bringing your thoughts back together?
