Whereas Merton identifies the function of a paradigm in analysing data obtained within a social study, Kuhn considers a paradigm as a key notion at a certain stage of the development of science – that of normal science. It is stressed that, despite differences in approaches, the theories do not contradict but rather complement each other.
