While the statement in itself is probably objectively false, it still is a good way to get people to start a Zettelkasten. And I will probably include this in the getting started with Zettelkasten section of my book on how to study effectively.

The reason the statement is probably false lies in the fact that information does indeed have superiority over other information depending on the connections, it's up to us to find the strength of those connections (In AI this is known as weight values), which is on par with Evaluation on Bloom's Taxonomy, the highest form of learning, only below creation itself.
