Respecting your readers' intelligence is crucial while writing, what are the things you have to avoid so as to have a credible plot?

People argue to settle differences of opinion. Using intelligence and reasoning in an exchange of words rather than blows, arguers strive to convince their audience to accept an idea, course of action, or point of view. In his book The Elements of Reasoning, Professor Edward Corbett has written, “When we argue informally with fiends and acquaintances, many of us resort to arguing by vigorous assertion rather than by reasoned demonstration”: Reliable evidence and logical presentation sometimes take a back seat to shouting and demotion. However, sound and fury rarely persuade people as successfully as a convincing presentation of well-marshaled facts.

Your history exam requires that you write a short essay answering the question, “What caused the end of the Cold War?” Your boss asks you to prepare a report comparing two computer software packages and recommending the one that seems better. To cut costs, the school board is thinking of closing your child’s school, sending him or her to a more distant one. You decide to write a letter to the local newspaper in protest.
