You followed the reference and a real document opened. Answering that was the previous question. The one here is whether the document actually says what the sentence claims.
Two sentences, each with a working reference beside it. Open both documents and only one of them contains the sentence.
“The policy allows five days' notice.” Reference opens the correct policy, current version.
“The policy allows ten days' notice for planned absence.” Same reference, same document.
One is a reference sitting beside a claim. One is a document that contains the claim.
Opening a real document is one bar. Containing the sentence is a different one. A study can be genuine, current and correctly cited and still cover one team at one company, which does not carry a claim about remote work in general.
The gap is invisible from the page, because a reference looks identical whether or not anybody read what it points at. Four ways it fails: the quote is not there, the study is too narrow for the claim, the figure appears nowhere, or the document is about something adjacent.
Tap a claim, then tap whether the source backs it. Then see exactly what each source really says.
Pick a situation. In every one, the reference opened a real document.
The policy opens. The right policy, the current version, the right section. The quoted line is not anywhere in it.
Five questions. Nothing is scored.
Five terms, not two. Tap one.
AI models often generate citations based on keywords or patterns, not careful reading. Sometimes, the citation is real but only loosely related to the claim. Always check whether the source actually supports the sentence, not only whether it exists.
No. A citation only tells you where to look, not that the claim is correct. The source may not match the sentence, or might only partially support it. Always check the source if the claim matters for your work.
| Aspect | Citation presence | Citation support |
|---|---|---|
| What it means | A citation is attached to a claim | The source actually backs up the claim |
| How to check | See if a citation is present | Read the source and compare to the claim |
| Risk | False sense of security | Takes more time, but gives real confidence |
Yes. Sometimes the citation points to a genuine source, but the source does not address the claim, or only covers part of it. This is a common failure in AI-generated research and summaries.
On the page, a citation looks like a stamp of approval. A reference sitting beside the claim makes it easy to assume the source supports it. In reality, only reading the source tells you if it matches.
A citation looks official and suggests careful work. When you see it, you might assume the claim is checked and correct. Unless you read the source, you cannot know if the citation actually supports the claim.
No. Even when the citation is real, you have to check the source to see if it matches the claim. AI sometimes links to plausible sources that do not actually contain the information claimed.
You can say: 'A citation shows where to check, not that the claim is correct. Only reading the source tells you if it really matches the sentence.'
Some tools try to match claims to sources, but none are perfect. For important claims, you still need to check the source yourself. Automation can help, but it does not replace careful reading.
Suppose an AI answer claims, 'This policy increased productivity by 20%' and cites a study. If the study only discusses the policy, but not the productivity figure, the citation is present, but does not support the claim.
Citation presence only shows there is a source. Citation support means the source actually backs up the claim. For work that matters, only support gives you confidence to act on the information.
Yes. Sometimes a source supports part of a claim, but not all of it. For example, it might confirm a trend but not the exact number. In these cases, you should clarify what is supported and what is not.
A reference that opens has cleared one bar. Whether the page it opens on contains the sentence is a different bar, and the only one a reader cares about.
