Readers see information in a linear sequence. You don't sell an article unless you prove to an editor you write for the reader, not the writing critic. Writers think in a complex manner. You know you do whether you admit it or not. You think, plan, sketch notes, prioritize ideas, organize your writing in sections and categories to provide the best method to get your thoughts on paper and into someone else's mind.
Writers have a sophisticated view of their own material.
They see it in coordinate division and development direction. In other words, they originate a core idea which branches into a couple of sections which carry their own thought and sentences with examples, points of interest, and other such 'slam dunk' methods or communicating into even further branches and categories. You understand the concept. Readers see information linearly. They read from beginning to end and expect it to flow.
