Just to be clear, "shockingly dumb" is in reference to the incorruptibility belief, not to your claim that it's "everyone".

Though from your response, I think you probably understood what I meant despite the ambiguous phrasing.

Oh, I didn't know! I thought you meant that the claim that there were literally zero people who thought they were corruptible was shockingly dumb, and I agreed, even though (construed literally) it's what I had said. Thanks for clarifying!
