From Wikipedia, the free encyclopedia
An epistemological paradigm shift was called a scientific revolution by epistemologist and historian of science Thomas Kuhn in his book The Structure of Scientific Revolutions.
A scientific revolution occurs, according to Kuhn, when scientists encounter anomalies which cannot be explained by the universally accepted paradigm within which scientific progress has thereto been made. The paradigm, in Kuhn's view, is not simply the current theory, but the entire worldview in which it exists, and all of the implications which come with it. There are anomalies for all paradigms, Kuhn maintained, that are brushed away as acceptable levels of error, or simply ignored and not dealt with – a principal argument Kuhn uses to reject Karl Popper's model of falsifiability as the key force involved in scientific change.
