The KK principle says that if you know something, then you know that you know it. KK is a controversial principle. It plays important roles in economics, computer science, and in theories of linguistic communication. But many philosophers have rejected it. We give a new argument against KK: we argue that if anyone doubts the principle, then it is false. Then we defend our argument against a battery of responses, which appeal to fragmentation, modes of presentation, and diagonalization. We show that the responses fail, sometimes in surprising ways.
