What problem does the noise create?

The “noise” is randomly scattered throughout the book, and it distracts our attention from the book’s explanation. So the noise is creating the following problem: Every time you read a book, you miss important information. All non-fiction books come with the “noise” problem built-in.

The noise can be a sentence, a paragraph, multiple paragraphs, even a complete page. A typical book can have more than 100 cases of “noise” scattered in random places. That’s a lot of distraction.

Which explains why we tend to miss key messages and information when we read a full-length book.
