It is called falsificationism to philosophical doctrine who is applying to falsifiability as a beginning to distinguish between what is scientific and what is not. For its part, falsifiability refers to the condition of falsifiable: What can be faked (refuted or denied).

FalsificationismFalsificationism was developed by Karl Popper. According to this Austrian thinker, contrasting of a theory or hypothesis consists of a attempted rebuttal through a counterexample. When such a refutation cannot be achieved, the theory is understood to be checked and therefore it can be accepted.

Popper, however, it indicated that there is no totally true theory. For falsificationism, an uncontested theory is accepted as valid but always provisionally.

This stream of the epistemology, baptized by Popper What critical rationalism, is one of the sustenance of the scientific method. The falsificationism emerged as an option against the verificationism, based on the incorporation of observational facts as a corroboration of the theory.

There is, therefore, a conceptual differentiation between falsificationism and verificationism. The demarcation criterion proposed by Popper indicates that when a theory is falsifiable, it is scientific. On the other hand, if the theory is not falsifiable, it cannot be considered as part of the science.

In short, falsificationism allows accept or reject a theory as scientific. The theory that can be falsified is scientific, since it is possible to test it and disprove it with experiments or facts. Thus, a theory is provisionally corroborated with empirical evidence, although it is never definitively confirmed.
