We frequently hear the words Information and Knowledge used as if they are the same thing. Firstly, let’s look at Knowledge. Knowledge is what we know. It also contains our beliefs and expectations. “If I do this, I will probably get that.” Crucially, the brain links all these things together into a giant network of ideas, memories, predictions, beliefs, etc. Information allows us to expand our knowledge beyond the range of our senses. Information is processed data whereas knowledge is information that is modeled to be useful.
