Metaknowledge

Knowledge about knowledge itself—awareness of what you know, what you don't know, how you know, and the limits of your knowing. Metaknowledge includes knowing your epistemic strengths and weaknesses, understanding the reliability of your sources, recognizing when you're in a domain of ignorance, and having a sense of how knowledge is structured and validated. It's not just knowing facts—it's knowing about knowing. The most dangerous ignorance is not lack of knowledge but lack of metaknowledge—not knowing that you don't know, not understanding the limits of what you think you understand.

"He's read a lot about vaccines, so he thinks he knows. But he has no metaknowledge—no understanding of how medical knowledge is validated, no awareness of his own cognitive biases, no sense of what he doesn't know. Metaknowledge is knowing what you know, how you know it, and—crucially—what you don't. Without it, information is just ammunition for ignorance."
