WHAT IS A PARADIGM SHIFT?
In 1962, Thomas Kuhn wrote The Structure of Scientific Revolution, and fathered, defined and popularized the concept of "paradigm shift" (p.10). Kuhn argues that scientific advancement is not evolutionary, but rather is a "series of peaceful interludes punctuated by intellectually violent revolutions", and in those revolutions "one conceptual world view is replaced by another".
Think of a Paradigm Shift as a change from one way of thinking to another. It's a revolution, a transformation, a sort of metamorphosis. It just does not happen, but rather it is driven by agents of change.
For example, agriculture changed early primitive society. The primitive Indians existed for centuries roaming the earth constantly hunting and gathering for seasonal foods and water. However, by 2000 B.C., Middle America was a landscape of very small villages, each surrounded by patchy fields of corn and other vegetables.
