What assigns economics as a unique science is that its particular theorems do not require verification or falsification on the grounds of experience, but rather, the ultimate measure of economic theories is solely reason unaided by experience. 33-39.

Godfrey Smith suggests a Popper's popularity stemmed from his attempt to reject the classical observationalist or the inductivist account of scientific method, and instead advancing empirical falsification instead, among others. the perspective of the philosophy of science, it is doubtful whether the Assuming that the failed observations are repeatable, we would also require evidence that the observation itself is valid, meaning that there is a true and verified theory underlying the theory of the instrument. Karl Popper is known for his celebrated theory,Falsificationism. As a result, Popper identified four steps in the deductive process. While advocating Falsifiability as the criterion of demarcation for science, Popper notes that in practice a single conflicting or counter-instance is never sufficient to falsify a theory, and that scientific theories are often retained even though much of the available evidence conflicts with them, or is anomalous with respect to them. scientific field of evolutionary biology in the 1990s.
