Information and Meaning Are Not the Same Measurement

How much information a message carries and how meaningful that message is to a person are different questions. Mathematical communication theory can measure specific aspects of uncertainty and representation without directly measuring human memory, context, or value.

Imagine two people reading the same sentence. The characters are identical, but one person learns something new while the other already knew it. A tiny personal message can also matter enormously to someone. Byte count does not contain that value.

If this distinction is ignored, a technical definition starts being used as an answer to every philosophical question. A definition should be judged by the job it was designed to do. Moving it into another question requires another layer of interpretation.

The concept of information is powerful to me precisely because it captures some relationships with great precision. Expanding it until it becomes identical to every kind of meaning would weaken that precision. Using the same word is not the same as using the same definition.
