Appropriate Style for My Research Paper

The styles I am going to use for my paper are clarity and emphasis. Since this is a research paper in which we have to argue our point, I want to make sure my point is clear and that I emphasis on important details. I want to avoid all unessesary words, sentences, paragrahs. I don't want the audience to think I am desperate (might make me seem crazy) but I want them to see how serious my argument is, without any question.
