To debunk an idea is to take it apart in public and show that it does not stand up — that the story, the “fact,” or the belief is false or wildly overblown. Journalists, scientists, and internet writers debunk myths, rumours, and miracle cures. The word is not as stiff as disprove, and it often has a slightly sharp, even cheeky feel: look, this famous claim is bunk (nonsense).
