Thomas Kuhn and Why Paradigms Shift

The term "paradigm shift" was coined by the American philosopher Thomas Kuhn (1922-1996). He argued that science couldn't advance until most people working within a field agree upon a paradigm. Before the agreement, collaboration and teamwork are restricted.

Once a paradigm theory is established, those working within it can start doing normal science. But now and then, normal science reveals anomalies that can't be explained within the dominant paradigm. When the inexplicable results start piling up, it eventually leads to a "crisis."
