Meaning of falsificationism (What is it, Concept and Definition)

What is falsificationism:

Falseationism is an epistemological doctrine applied to sciences that proposes falsehood as a criterion to distinguish what is science from what is not .

As such, it is a philosophical theory work of the Karl Popper methodologist, postulated in 1934 in his work The logic of scientific research .

The falsificationism argues that to verify a theory it is necessary to try to refute it through a counterexample .Why? Because the only way to corroborate the provisional validity of a theory is when it is not possible to refute it.

From this point of view, No theory can be considered absolutely or definitely true, but even not refuted .Yes, the criterion of verification of a theory will not be that of its verifiability, but that of its falsifiability.

Popper's falsificationism also criticizes the principle of verifiability, which implies that, regardless of whether we have a lot of evidence to affirm one thing, that does not mean that we will not find a proof that breaks our previous observations below.

A typical example to illustrate this is that of crows, not because all the crows we have seen so far are black necessarily imply that they all be.bump into one that isn't if we can say that not all crows are black os.

Hence the method of falsificationism proposes the advancement of sciences by falsifying successive theories to, thus, knowing what does not it is , to be closer and closer to what if it is .

Within methodological falsificationism there are two main currents :

• Naive falsificationism , which is Popper's initial theory, with his criticism of the principle of verifiability and the consequent need for refutation as a form of validation, and
• Sophisticated falsificationism , which is the one developed late by Popper and criticized and reformulated by Imre Lakatos, according to which science does not advance only by refuting theories (as many scientific theories are born refuted), but with the scientific research program, which is a structure that guides future research.

Etymologically , falsificationism is formed from the union of the noun falsification and the suffix -ismo , which indicates 'doctrine' or 'system'.The falsification, on the other hand , is the 'action of falsifying', that is, of refuting a hypothesis or theory based on evidence or experiments.Originally, falsificationism was called by Popper as critical rationalism .
