Thesis statements...
- give a preview of what arguments you'll be making
- usually one sentence long
- last sentence of your introduction paragraph
Thesis statements should be:
Specific
lay out exactly the arguments/reasons you're using in your thesis
Contestable
if you can find a definitive yes/no answer within a few minutes of Google searching, it's not arguable enough
Narrow
not about all of [topic], but this little sliver of a [topic] in a particular context
Provable
or at least something you can persuasively argue
