The action of proving something false or the process of showing that a scientific theory or hypothesis is incorrect through contradictory evidence. In philosophy of science, it's Karl Popper's criterion for distinguishing science from non-science.
From Latin falsificare, meaning 'to make false,' composed of falsus (false) + facere (to make). Philosopher Karl Popper elevated this term to central importance in scientific methodology during the 20th century.
