Once you have read a variety of sources, considered your issue from different perspectives, and chosen an entry point in the research conversation (see R1-b), you are ready to form a working thesis: a one-sentence (or occasionally a two-sentence) statement of your central idea. (See also C1-c.) Because it is a working, or tentative, thesis, you can remain flexible and revise it as your ideas develop. Ultimately, the thesis will express not just your opinion but your informed, reasoned answer to your research question (see R3-c). Here, for example, are student writer Ned Bishop’s research question and working thesis statement.
research question
To what extent was Confederate Major General Nathan Bedford Forrest responsible for the massacre of Union troops at Fort Pillow?
working thesis
By encouraging racism among his troops, Nathan Bedford Forrest was directly responsible for the massacre of Union troops at Fort Pillow.
Notice that the thesis expresses a view on a debatable issue—an issue about which intelligent, well-meaning people might disagree. The writer’s job is to persuade such readers that this view is worth taking seriously. To read Ned Bishop’s thesis in the context of his introduction, see CMS-5b.
