To alter or present information dishonestly in order to deceive; to prove something to be false or incorrect. It can mean both deliberate deception and the process of disproving.
From Old French 'falsifier,' derived from Latin 'falsus' (false) and 'facere' (to make). Originally meant simply 'to make false,' but developed dual meanings of deception and disproof in different contexts.
In science, falsifying a theory is actually a good thing—it's how we make progress! Karl Popper argued that the best theories are those that can be falsified, because unfalsifiable claims aren't really science at all.
