The principle of falsifiability with the term “falsification” is introduced by Popper which is a theory refuted by empirical observations which contradict the implications of this theory. This theory came to refute the method of induction of logical positivism. For example, a given statement "All sapphires are blue" is considered true in general, but Popper argued that even if 99 sapphires are observed and they are all blue, the statement still should not be considered true . Therefore, it will turn out to be false if the newly discovered 100th sapphire is pink in color even though the color of the first 99 sapphires is blue. Thus, using falsification, it can be determined whether the theory or statement is verified by inferring a false statement. Say no to plagiarism.

Get the original essay Popper claimed that scientific theory should contain the principle of falsifiability and that its falsifiability is increased when empirical content; the number of potential forgers is higher and, according to a previous statement, the number of potential forgers is the "chance that the color of sapphire is not blue". Popper criticized logical positivism, particularly the verifiability principle of scientific methodology, according to which science can be distinguished from pseudo-science on the basis of its inductive methodology. Scientific theory starts by suggesting problems (theory) and the theory which proves false by falsifications is deduced, finally the remaining theories will remain true by repeating conjectures and refutations. Therefore, this may increase the likelihood that the theory will come true. be true. However, a statement or theory can remain true using three immunization stratagems. First, when a pink sapphire is found, we can "reclassify" that the pink sapphire is not a sapphire because, like our statement, the sapphire should be blue. Second, we can “adjust the underlying theories” by insisting that pink can be considered blue. The last way is to change the domain, if the pink sapphire is founded in the United States, we can change all the sapphires in South America to blue. By using these 3 immunizing stratagems, the statement “Every sapphire is blue” can remain true. The theory introduced by Kuhn explains that a paradigm can provide puzzles to scientists and this is called normal science. New scientific theory can be developed by recognizing an anomaly. However, there is a probability that the theory is degenerate, due to incommensurability. Keep in mind: this is just a sample. Get a personalized article from our expert writers now. Get a Custom Essay According to Kuhn, incommensurability shows that two competing paradigms cannot be compared because there are no independent standards of evaluation or there is a misunderstanding between the new paradigm and the old paradigm. Therefore, Adjust's underlying theories can improve theory development by giving a new paradigm. Also from the Lakota perspective, a theory will be developed when it is either theoretically progressive or empirically progressive and this progress is measured by the degree to which a series of theories results in the discovery of new facts. But the theory will degenerate if there is no progress.
