Some journals abbreviate and de-emphasize methods and bibliography, and many journals impose a word limit on papers.
Scientists read papers with differing degrees of attention and skepticism.
Sometimes we read just to find out what is happening in a field that is tangential to our own, and our reading is rather casual, like the way we might read a magazine. Often, however, we want to learn the results and interpretation of other researchers working on a particular problem of intense interest. At our most critical, scientists may bring a kind of intellectual machismo to a published paper. In this mode, we are ready to assume that authors, reviewers, and editors have all had major lapses in thinking, and only our own critical sensibility can prevent our friends and students from sinking into a scientific swamp. We focus on the data presented in the results section, usually presented as graphs, tables, or photographs.
