All academic writers use evidence to support their claims. However, different writing tasks in different fields require different types of evidence. Evidence is not simply “facts”. Evidence is not simply “quotes”.
Evidence is what a writer uses to support or defend his or her argument, and only valid and credible evidence is enough to make an argument strong. What is valid or credible changes, however, according to the academic discipline.
