Falsification is a procedure used in science to test the validity of a hypothesis or theory. It involves stating some output from theory in specific and finding contrary cases among experiments or observations.

Popper's notion that you can only prove something to be true by failing to falsify it. Positivism

The effort to prove a hypothesis or theory incorrect in order to exclude it as an explanation.

Dubious method used by followers of the famous 'philosopher' Karl Popper to disqualify truths that they 'rationally' distrust.

based upon the philosophy of Sir Karl Popper, falsification is said to be the cornerstone of science -- that is, a theory is only scientific to the extent that there is a potential for falsification; the goal of falsification is to refute (prove incorrect) a theory based upon observations gained through the scientific method; a theory or technique is falsifiable if it has been, or has the potential to be, tested.

falsification refers to the idea that science progresses through a process of trying to disprove or falsify existing hypotheses.

A standard of a sound scientific proposition coined by Philosopher of Science Karl Popper. A good scientific proposition is meant to have ways by which demonstration of evidence in certain direction would reject the hypothesis. In other words, if a proposition, in its conception itself, does not provide indications of means by which it could be evidentially rejected, the proposition is not considered to follow the terms of falsification, and thereby of sound scientific hypothesis.

If an idea/theory/hypothesis cannot be subject to a test that would prove it false, the idea/theory/hypothesis is not scientific, (ala Sir Karl Popper and Judge William Overton).

It is a process that seeks to prove that a hypothesis is false. When something cannot be proven to be false it is considered not-false. In common language it is called to be true.
