Found in 8-12% of dissertations we analyze. Every uncited assertion is an invitation for your committee to write "citation needed" in the margin.
Add a citation immediately after this claim.
An unsupported claim is any statement presented as fact without a citation to back it up. In everyday writing, you can say "teachers are overworked" and nobody bats an eye. In a dissertation, that sentence without a source is an opinion masquerading as scholarship.
Committees flag unsupported claims more than almost any other issue because they strike at the heart of what makes academic writing academic: evidence. Your dissertation isn't a persuasive essay where rhetorical force carries the day. It's a scholarly argument where every link in the chain needs to hold up to scrutiny.
The tricky part is that many unsupported claims don't feel unsupported to the writer. After months of reading, you internalize findings so deeply that they feel like common knowledge. But your committee doesn't know which ideas came from your reading and which came from your assumptions—and they're not going to give you the benefit of the doubt.
Assertions without citations are opinions, not scholarship. Committees demand evidence for every claim because dissertations must be defensible—unsupported statements invite challenges during your defense.
