refutation
disproof / rebuttal / denial
Noun
pl: refutations
This term carries a strong connotation of intellectual victory and definitive proof. It is most frequently employed in formal, academic, or legal settings where a claim is not merely questioned, but systematically dismantled using logic or empirical evidence. While often confused with denial, a refutation requires the presentation of evidence to prove a falsehood, whereas a denial is simply a statement that something is not true. It describes both the process of debunking and the resulting argument that achieves this goal.
