Fake citations and real source trails

A real trail has links you can walk:

1. Name — Who said it?
2. Where — Book, site, article, video, teacher handout?
3. Findability — Can you open it and see the same claim?
4. Fit — Does the source actually support your sentence?

Fake citations often fail at step 3. They have the shape of scholarship (author, year, journal) without a door you can open.

Treat every AI-supplied citation as a hypothesis: “Maybe this exists.” Your job is to prove it before it enters your paper.

• Prefer sources your teacher accepts: textbook, library database, assigned articles.
• If AI suggests a source, search the exact title in quotes.
• If you can’t find it in two minutes, drop it — don’t “hope” it’s real.
• Quote only what you personally read.

Also watch for “almost real” mistakes: real author, wrong year; real journal, wrong article; real study, wrong number. Those still fail a trail check.

School prompts often say “include a citation.” Models know what citations look like. When they cannot retrieve a real one, they may still complete the pattern: Author (Year). Journal. Pages. That is costume jewelry — shiny, not precious.

Teachers are getting better at spotting this. So are plagiarism checkers and simple web search. Getting caught with a fake source is worse than turning in fewer sources you actually read.

Build a “trail or trash” rule: if you cannot open it, it does not enter the draft. Period. Use AI to suggest keywords for your library database, then cite what the database returns. That keeps the tool in a helper role and keeps you as the researcher of record.

• DOI links that 404
• Quotes that do not appear in the cited article
• Perfect statistics with no methodology

Each of those fails a trail check even when the formatting looks teacher-ready.
