The phenomenon of a sudden “a-ha” moment can be thought of as the result of crossing a threshold for cognitive reorganization. Before reaching the threshold, there is nothing in conscious awareness but once the dots all snap into place with a thread of unexpected connection to create a discernible pattern (where before there was none), there is a release of energy, often both relieving and joyful.
The cognitive system then enters an extended refractory period where it begins energizing once again but is unable to reorganize for a period. It is as though the new insight has a gravitational pull on the newly organized ideational elements that locks the emergent pattern, and the system that contains it, in place.This is the paradox, that initial insight might not be all there is to know!
