Falsifiability or refutability is the trait of a statement, hypothesis, or theory whereby it can be shown false by way of some conceivable observation practically possible to achieve. In this sense, falsify is synonym to nullify, meaning not "to commit fraud" but "show to be false". (From Wikipedia)
Karl Popper championed this doctrine in Philosophy of Science. Popper coined the term "critical rationalism" to describe his philosophy. Concerning the method of science, the term indicates his rejection of classical empiricism, and the classical observationalist-inductivist account of science that had grown out of it. Popper argued strongly against the latter, holding that scientific theories are abstract in nature, and can be tested only indirectly, by reference to their implications. He also held that scientific theory, and human knowledge generally, is irreducibly conjectural or hypothetical, and is generated by the creative imagination in order to solve problems that have arisen in specific historico-cultural settings.
