refutabile

Refutabile is a term used in philosophy and logic to describe a statement, claim, or theory that can be proven false through evidence or logical argument. The core concept of refutability is central to the scientific method, where theories are not accepted as absolute truth but rather as the best current explanations that are subject to revision or rejection if new evidence contradicts them.

A statement is refutable if there exists a conceivable observation or line of reasoning that would demonstrate its falsity. For example, the statement "all swans are white" is refutable because the observation of a single black swan would prove it false. Conversely, a statement that cannot be falsified, regardless of evidence, is considered irrefutable. Often, such irrefutable statements are tautologies (true by definition) or rely on unfalsifiable claims, such as those involving supernatural phenomena where no empirical test can be devised.

The principle of refutability, often associated with philosopher Karl Popper, distinguishes scientific hypotheses from non-scientific ones. Science progresses by proposing theories that are not only testable but also open to being disproven. The ongoing process of attempting to refute existing theories drives scientific inquiry and refinement, leading to a more accurate understanding of the natural world. A theory that has withstood numerous attempts at refutation is considered robust, but it remains open to future challenge.
