Classroom instructors can set up learners for success in the research and writing process when they give learners a clear sense of what constitutes "credible" and "authoritative" in a specific course (and for a specific assignment). Context (and, to some degree, privilege) determines what's valid, appropriate, authoritative. We oversimplify (and behave inauthentically) when we suggest evaluating sources is anything short of complicated.
