Failifiable

Failifiable refers to a characteristic of a claim, hypothesis, or theory that it can be proven false through observation or experimentation. It is a core concept in the philosophy of science, particularly associated with the work of Karl Popper. A statement is failifiable if there are conceivable circumstances under which it would be demonstrated to be incorrect. For example, the statement "all swans are white" is failifiable because the observation of a single black swan would disprove it.

Conversely, statements that are not failifiable are often considered unfalsifiable or pseudoscientific. These are claims that cannot be tested or disproven, no matter what evidence is presented. Examples might include certain metaphysical statements or overly broad generalizations that can be reinterpreted to fit any outcome. The principle of failifiability serves as a criterion for distinguishing scientific propositions from non-scientific ones. Science progresses by proposing theories and then rigorously attempting to falsify them. Theories that withstand repeated attempts at falsification are considered robust, while those that are falsified are either modified or discarded. This ongoing process of testing and refinement is fundamental to scientific inquiry.
