I'm not saying that no one has any trace of stupidity. I'm saying that the concept of stupidity-intelligence is not a binary, it is a gradient.
What I'm arguing is that the question reveals its flaws, and the flaws of the lesswrong community. A member who self-identifies as part of that community is either being redundant by saying something about themselves that applies to every human being, or they are being elitist by implying that they have (or seek, and therefore have) some special understanding of the universe.
This is illustrated because Kenneth is dividing the world into people who are right and wrong and wondering if being wrong can sometimes be right. It's nonsense, a question brought about by too much caring how right you can be.
