For most (not Peek), memory and knowledge are necessarily linked since memory tends to work better when there is a previously existing connection to attach a new piece of information to. So, we don't tend to remember facts for the sake of facts. This obviously isn't always true, but for vast amounts of information, it would be very difficult to remember single "nodes" of information without having some connection to other information. Memory contestants use this to their advantage, by creating some sense of story and/or place to attach the otherwise arbitrary information, like digits or cards, to.
