ELI5: Explain Like I'm 5

Metaknowledge

Metaknowledge is knowledge about knowledge. It's a way to learn about all the information that already exists instead of trying to figure out something that someone else may have already figured out. For example, instead of learning all the scientific facts about mountains, you could use metaknowledge to figure out who the experts in mountain science are, what books and articles have been written on the subject, and which websites have good information about mountains. All of this information is knowledge about the knowledge that's out there so it helps us to find the best sources of information quickly and easily!
