falsifikointi

Falsifikointi, also known as falsification or refutation, is a key concept in the philosophy of science, particularly associated with the work of Karl Popper. It refers to the idea that a scientific theory can never be proven true, but it can be proven false. A theory is considered falsifiable if there is some conceivable observation or experiment that could demonstrate its incorrectness. This criterion distinguishes scientific theories from non-scientific or pseudoscientific ones, which often make claims that cannot be tested or disproven.

For a theory to be scientific, it must make specific, testable predictions about the natural world. If these predictions are not borne out by empirical evidence, the theory is considered falsified. Popper argued that scientists should actively seek to falsify their own theories through rigorous testing. This process of trial and error, where theories are proposed and then subjected to attempts at falsification, is central to scientific progress. Theories that withstand repeated attempts at falsification are considered to be well-supported, but never definitively proven true.

The principle of falsifiability has had a significant impact on how scientific knowledge is understood. It emphasizes the provisional nature of scientific understanding and the importance of empirical evidence in evaluating scientific claims. Theories that are not falsifiable, such as those that can be endlessly reinterpreted to fit any data, are generally considered to be outside the realm of science.
